Description

The present invention relates to a medical or training device that uses physical therapy, particularly electrical stimulation, to treat, restore, improve, or train weak, dysfunctional, or paralyzed body parts, particularly wrists and fingers.

Current stimulation based on physical therapy, particularly electrical treatment devices, has been put to practical use. Low-frequency electrical signals are often used in physical therapy using current stimulation, and are used to treat joint injuries, improve muscle fatigue, or prevent injuries. On the other hand, electrical signals are also applied to muscles to move them and strengthen them as training equipment. Using this principle, devices have been proposed for rehabilitating fingers whose function has been reduced due to paralysis, and devices that provide virtual sensations, such as the one in Patent Document 1.

Japanese Patent Application Laid-Open No. 7-020978

In order to send electrical signals to muscles and ensure efficient muscle contraction, it is necessary to supply an appropriate current to the so-called motor points, which are specific points unique to each muscle and provide efficient muscle contraction. Motor points exist individually for each muscle, and their positions and required currents vary slightly depending on age, sex, individual differences, and other factors. For example, the motor points for bending a paralyzed finger may be different for each person depending on the reason for paralysis, the duration and degree of paralysis. Furthermore, motor points for muscles that bend or straighten a finger individually may exist individually for each finger. Furthermore, it should be considered that these multiple motor points may exist very close to each other. Therefore, when performing training, exercises, treatment, or rehabilitation (hereinafter collectively referred to as training) that moves each finger individually, it is necessary to accurately identify these multiple motor points and reliably apply an appropriate stimulation current only to the necessary motor points. However, it is difficult to identify each motor point and the required current value, and there is a problem that the desired training cannot be performed efficiently or the efficiency of these cannot be improved.

In order to solve the above problems, the present invention provides the following means: (1) a current stimulation device including a base, one or more fixing belts for fixing the base to the forearm, and an appliance having an electrode belt on which a plurality of electrodes are arranged, the base having a positioning device for determining the relative position of the appliance and the forearm, the electrode belt being attached to the base by a fixture, the base having an attachment part for attaching the fixture, and the electrode belt being capable of changing the relative position of the electrode belt with respect to the forearm by the attachment part and the fixture.

Furthermore, the present invention is characterized in that (2) the orthosis is connected to an output unit, and the output unit outputs an electrical signal required for a selected operation to a specific electrode among the multiple electrodes .

The present invention is further characterized in that (3) the output unit is connected to a control unit, and the control unit is used to determine the specific electrodes capable of supplying electrical signals to the motor points and the electrical signals required for the selected operation .

The present invention provides a device that can be used for training to achieve a desired movement by applying a stimulation current to a specific motor point, thereby improving the efficiency of the training.

[First embodiment]
1 shows a training device 1 according to the present invention. As described below, the training device 1 includes an orthosis 11, an output unit 12, a control unit 13, an electrode belt R24 attached to the orthosis 11, a cable A14 connecting the electrode belt R24 and the output unit 12, a cable B15 connecting the output unit 12 and the control unit 13, an elbow electrode 17, and a cable C16 connecting the elbow electrode 17 and the output unit 12.

Figure 2 shows the brace 11. In Figure 2, (a) is a top view, (b) is a bottom view, (c) is a front view, (d) is a rear view, (e) is a left side view, and (f) is a right side view. The brace 11 has fixing belts A22 and B23 at both ends of the base 21, and the fixing belts A22 and A22 are wrapped around the forearm of the trainee to fix the brace 11 to the forearm of the trainee. The fixing belts A22 and B23 are preferably attached to the wrist or a part very close to the wrist, or to the elbow or a part very close to the elbow so as not to interfere with the movement of the forearm muscles, the identification of motor points, or the attachment of electrodes. Furthermore, the brace 11 has a positioning means, a positioning device 29, at the tip of the base 21 on the wrist side. In this embodiment, for convenience, the trainee receiving the training is described as the user of the training device 1.

A cushion 28 is provided on the surface of the fixing belt A22 facing the forearm. The fixing belt A22 is wrapped around the forearm and used to fix the brace 11 to the forearm, so the cushion 28 is provided to reduce the burden on the forearm. The cushion 28 is preferably made of a foam material such as sponge, but it can also be made of urethane or silicone, cotton, cloth, or an airbag. An electrode belt R24 for the right hand, for example, as described below, is attached to the attachment part A26 of the brace 11 by a fixing device R25. The electrode belt A24 can be fixed to any position on the attachment part A26 by the fixing device R25.

The present invention is not limited to using only one electrode belt R24, and multiple electrode belts having a similar structure to electrode belt R24 may be used in combination, i.e., two or more electrode belts may be used. Electrode belt R24 is an electrode belt for the right hand, and by attaching electrode belt L27 for the left hand instead of electrode belt R24, the orthosis 11 can also be worn on the left hand. The electrode belt L27 for the left hand may also be configured in the same manner as electrode belt R24 for the right hand, and its shape may be configured to be symmetrical on the left and right sides to be worn on the left hand. Multiple electrode belts for the left hand may also be used.

Figure 3 shows the electrode belt R24. In Figure 3, (a) is a top view, (b) is a bottom view, (c) is a front view, (d) is a rear view, (e) is a left side view, and (f) is a right side view. The electrode belt R24 is composed of a belt base material 31, an electrode holding portion 32 formed on the belt base material 31, a plurality of conductive electrode portions 33 on the electrode holding portion 32, a belt fixing portion A34, a belt fixing portion B35, a belt fixing portion C36, a belt end portion A37, a belt end portion B38, etc. Each electrode portion 33 is connected to the output unit 12 via a cable A14 by a harness (not shown) arranged in the belt base material 31. In Figure 3, 14 electrode portions 33 are arranged, but the present invention is not limited to this number, and may be 13 or less or 15 or more.

The electrode belt R24 is used by wrapping it around the right arm. First, as shown in FIG. 3(a), the electrode belt R24 is placed so that the electrode portion 33 faces upward. At this time, the electrode body 53 described below is placed on each electrode portion 33. Next, the arm is placed so that the electrode body 53 and the forearm are in contact, and the belt base material 31 is wrapped around the arm, bringing the belt end A37 and the belt end B38 close to each other, and the belt fixing part A34 is placed on the surface of the belt end B38 opposite the electrode body 53. The belt fixing part A34 and the belt end B38 form a hook-and-loop fastener, and the electrode belt R24 is wrapped around the arm and fixed by fixing the belt end B38 and the belt fixing part A34. When removing the electrode belt R24, the belt fixing part A34 is not peeled off from the belt end B38, but the belt fixing part B35 is removed from the belt fixing part C36.

The belt fixing part B35 and the belt fixing part C36 are simply fixed to each other by making one of them, for example, the belt fixing part B35 a magnet and the other, for example, the belt fixing part C36 a magnetic material such as stainless steel. Therefore, it is much easier to remove the belt fixing part B35 from the belt fixing part C36 than to peel off the belt fixing part A34, which constitutes the hook-and-loop fastener, from the belt end part B38, and the electrode belt R24 can be removed from the arm very easily. The configuration of the belt fixing part B35 and the belt fixing part C36 is not limited to a configuration using a magnet, and may be a configuration such as a snap button, as long as the force of fixing them to each other is weaker than that of the hook-and-loop fastener. In this way, two types of means for wrapping the belt around the forearm and fixing it are provided, and by changing the fixing force of these means, the length of the belt can be easily adjusted to suit the thickness of the user's arm, and it is also possible to make it extremely easy to put on and take off the belt. In other words, the part with the stronger fixing force is used to adjust the length of the belt, and after adjustment, the part with the weaker fixing force can be used to put on and take off the belt, making it easy to both adjust the length and put it on and take it off. On the other hand, if there is only a hook and loop fastener, it is very easy to adjust the length of the belt, but it may not be easy to remove it; for example, when fixing one arm as in this device, the hook and loop fastener must be removed only with the other arm, which is not easy. Conversely, if there is only a snap button, for example, it is very difficult to adjust the length. The configuration shown in Figure 3 can solve both of these problems at the same time.

Figure 4 shows a conceptual cross section for simply explaining the attachment of the electrode belt R24 to the attachment part A26 by the fixing device R25. Note that other components of the electrode belt R24 are omitted in Figure 4 to avoid the illustration becoming too complicated. A protrusion A41 is provided at the bottom of the fixing device R25. The electrode belt L27 for the left hand also has a protrusion B42 (not shown) at a position opposite to the fixing device R25 of the electrode belt R24. These protrusions A41 and B42 fit into the edges A43 and B44 provided on both sides of the attachment part A26 in Figure 4, so that the electrode belt R24 and the electrode belt L27 can be easily attached to any position of the attachment part A26, and the electrode belt R24 and the electrode belt L27 do not easily come off the attachment part A26 during training. In addition, a magnet 47 is attached to the bottom surface A45 of the fixing device R25, and the bottom surface B46 of the mounting part A26 is made of, for example, stainless steel, so that the fixing device R25 is attracted to the mounting part A26 by magnetic force, and the electrode belt R24 can be placed at any position on the mounting part A26.

Since training is repeated daily or periodically, the equipment used, for example the brace 11, is attached to and detached from the forearm each time. It is desirable to attach the brace in the same position each time, but the relative positions of the electrode body and the motor point often shift even slightly. Therefore, it is preferable to make the electrode somewhat large so that the desired current flows correctly to the desired motor point even if the positions of the motor point and the electrode shift slightly. However, if the motor point that moves a specific finger is very close to the motor point that moves another finger, if the electrode used is too large, when a current flows through the motor point that moves the specific finger, the current will unintentionally flow through the motor point of the other finger, causing the other finger to move as well. In this case, the desired training cannot be performed efficiently or the efficiency of these training cannot be improved.

On the other hand, it was revealed that motor points that can move fingers individually, i.e., motor points that can be used to train fingers, are not concentrated in a specific area of the forearm, such as the area near the elbow, but are distributed over a wide area of the forearm.

Therefore, it is desirable to have a configuration that allows motor points to be identified and used throughout the entire forearm. However, it is not desirable to place electrodes over the entire forearm, i.e., to increase the number of electrodes. Increasing the number of electrodes causes problems such as complication in handling the electrodes, attaching or mounting them to the forearm, and wiring for connection to the output unit 12.

In order to place electrodes over the entire forearm without changing the number of electrodes, it is possible to enlarge the electrodes. However, as mentioned above, it is necessary to avoid making the electrodes placed at the motor points larger than necessary. If electrodes are placed over the entire forearm without changing the number or size of the electrodes too much, the spacing between the electrodes will become larger. If the spacing between the electrodes becomes too large, it will be impossible to identify or use the motor points between the electrodes, which will cause the desired training to be performed efficiently or to be inefficient. Therefore, as in this embodiment, it is desirable to have a configuration in which the electrode belt R24 can be attached to any position of the attachment part A26 by the fixing device R25, and if the motor points cannot be detected or identified properly, the electrode belt R24 can be moved to detect and identify the motor points as if the electrode body 53 was placed at all positions on the forearm. In other words, since the electrode body 53 can be moved, there is no need to make the electrode body 53 larger, and all motor points can be detected and used regardless of the configuration of the brace 11, and this configuration can improve the efficiency of training.

When removing the fixing device R25 from the attachment part A26, it can be easily removed by lifting the part of the fixing device R25 that is close to the edge part B44 side and does not have the convex part A41 in the direction of arrow A in Figure 4. Conversely, when attaching the fixing device R25 to the attachment part A26, first engage the convex part A41 with the edge part A43, and then push the fixing device R25 in the opposite direction to the arrow in Figure 4, thereby attaching the fixing device R25 to the attachment part A26. The electrode belt L27 for the left hand performs the opposite operation.

Figure 5 shows an electrode pad 51 attached to the electrode belt R24. In Figure 5, (a) is a top view, (b) is a bottom view, (c) is a front view, (d) is a rear view, (e) is a left side view, and (f) is a right side view. The electrode pad 51 includes an electrode frame 52 and an electrode body 53 attached to the electrode frame 52. The electrode frame 52 separates each electrode body 53 from the adjacent electrode body 53 and holds each electrode body 53 at a fixed interval. The electrode frame 52 may be made of, for example, silicone, urethane, or natural rubber.

The electrode body 53 is a solid gel having electrical conductivity or extremely low electrical resistance and elasticity, and applies an electrical signal from the electrode section 33 to the forearm. The electrode body 53 is configured to have the same shape as the electrode section 33 and is equal to or larger than the electrode section 33, and further has some adhesiveness. Since the electrode body 53 has adhesiveness, not only can the electrode body 53 be fixed to the electrode section 33 without using adhesive means such as adhesive or double-sided tape, but the electrode material having elasticity and adhesiveness in this way also adheres well to human skin, preventing separation or poor contact between the electrode body and the skin due to training or muscle movement, which occurs even when the electrode belt is wrapped around the arm, and can avoid problems due to such separation or poor contact, such as the inability to properly supply current to the motor point, or the inability to secure a sufficient contact area, which makes the current path small and narrow, and thus pain and burns due to an increase in current density. For example, AquaJoint (registered trademark No. 5467295) manufactured by Nissan Chemical Industries, Ltd. can be used as such an electrode body 53.

The electrode pad 51 has the same number of electrode bodies 53 as the electrode parts 33 of the electrode belt R24, for example 14 electrode bodies 53, arranged by the electrode frame 52 so that they are in the same positions as the electrode parts 33 of the electrode belt R24. Therefore, by attaching the electrode pad 51 to the electrode belt R24, the electrode bodies 53 are reliably arranged on each electrode part 33 at the same time. This configuration not only eliminates the trouble and hassle of arranging the electrode bodies 53 one by one on the electrode parts 33, but also reduces the time required to arrange the electrode bodies 53 one by one on the electrode parts 33, thereby shortening the time required to prepare for training and improving the efficiency of the overall training.

Figure 6 shows a cross section to show the concept of the configuration of one opening 63 of the electrode body 53 and the electrode frame 52. The electrode pad 51 has a plurality of electrode frames 52 and electrode bodies 53, for example 14 pieces, arranged as shown in Figure 5, arranged as shown in Figure 6. The electrode body 53 is composed of electrode gel A61 and electrode gel B62. The electrode frame 52 has openings 63 smaller than the electrode body 53 and the electrode parts 33 at positions corresponding to the electrode parts 33 arranged on the electrode belt R24, and the same number of openings 63 as the electrode parts 33. By forming the electrode body 53 by matching the electrode gel A61 and the electrode gel B62 from both sides of the opening 63 as shown in Figure 6 (a), the periphery 64 of the electrode frame 52 is sandwiched between the electrode gel A61 and the electrode gel B62 as shown in Figure 6 (b), and the electrode body 53 is fixed to the electrode frame 52 to form the electrode pad 51. In addition, in Fig. 6, electrode gels of the same shape are used as the electrode gel A61 and the electrode gel B62, but this is not limited thereto, and the shape, adhesiveness, elasticity, or hardness of the electrode gel may be appropriately changed between the side in contact with the skin and the side in contact with the electrode section 33. For example, by making the adhesive strength of the electrode gel B62 arranged on the electrode section 33 side greater than that of the electrode gel A61 in contact with the skin of the forearm, when the electrode belt is removed from the forearm, the adhesive strength between the electrode body 53 and the skin becomes stronger than the adhesive strength between the electrode section 33 and the electrode body 53, so that the electrode pad 51 can be prevented from coming off the electrode belt R24, and the electrode belt R24 can be easily removed. In this embodiment, the electrode gel A61 and the electrode gel B62 are made of the same material and have the same adhesive strength, and the adhesive strength of both sides of the electrode body 53 is initially set to be the same. However, in actual use, due to sebum, dust, etc., the adhesive strength of the electrode body 53 to the skin becomes weaker than the adhesive strength of the electrode body 53 to the electrode part 33, and the adhesive strength of the electrode body 53 to the skin can be substantially made weaker than the adhesive strength of the electrode body 53 to the electrode part 33, which is desirable because it reduces the number of types of parts. Figure 6(c) shows a top view of the electrode gel A61, (d) a left side view, and (e) a front view. The top view, bottom view, front view, back view, left side view, and right side view of the electrode gel A61 have the same shape when drawn, so the bottom view, back view, and right side view are omitted. The shape of the electrode body is elongated in the direction that allows the electrode belt to move along the attachment part A26, so that even if the attachment position of the electrode belt RA81 or electrode belt RAB82 to the attachment part A26 shifts slightly, the electrode body can be reliably positioned on the motor point, and even if the brace 11, electrode belt RA81, or electrode belt RB82 is repeatedly put on and taken off, the electrode body will not shift relative to the motor point, and the efficiency of training is not reduced or can be improved.

Figure 7 shows a conceptual diagram of the positioning device 29. As shown in Figure 7, the base 73 of the thumb 72 on the palm 71 side is placed on the positioning device 29 to determine the relative position of the brace 11 and the forearm. The brace 11 is then fixed to the forearm by wrapping the fixing belt A22 around it. Using the positioning device 29 is desirable because it ensures that the relative position of the brace 11 and the forearm can be reproduced even if the brace 11 is repeatedly put on and taken off from the forearm. The degree of bending of the positioning device 29 may be adjusted by the individual user, and may also be adjusted appropriately for the same user depending on the level of training and the degree of recovery of paralysis and function.

In this embodiment, the positioning member 29 is initially straight as shown in FIG. 2, but is bent as shown in FIG. 7 during use. The positioning member 29 should be easily bent or stretched, or the degree of curvature should be easily adjustable, and should not easily deform when the brace 11 is repeatedly worn or trained; for example, a material with shape memory properties is desirable. Shape memory resins and shape memory metals can be used as materials with shape memory properties. A typical material with shape memory properties is, for example, a shape memory resin that can be easily deformed at temperatures of about 45°C to 50°C, but becomes very hard at room temperature and cannot be easily deformed.

Other materials that can be used for the positioning member 29 include, for example, a metal plate. If a metal plate is used, it becomes difficult to straighten or finely adjust the metal plate when the user cannot use both hands freely, for example, when training paralyzed fingers. If a metal that is relatively easy to bend is used to make it easy to straighten or adjust the metal plate with one hand, the metal plate will easily deform when repeatedly putting on and taking off the brace 11, making it difficult to accurately determine and maintain the relative position between the forearm and the brace 11. Therefore, in order to determine the relative position between the brace 11 and the forearm, a shape-memory resin is preferable as in this embodiment, or a shape-memory alloy or other material with shape-memory properties is preferable.

Figure 8 shows the state in which the brace 11 is worn on the forearm of the user. The figure shows an example in which two electrode belts R24 are used. However, the present invention is not limited to this, and one electrode belt R24 or three or more electrode belts R24 may be used. For convenience in the figure, the two electrode belts R24 are shown as electrode belt RA81 and electrode belt RB82, and the electrode bodies 53 arranged on the electrode belt RA81, which in this embodiment are 14, are referred to as electrode body AA801, electrode body AB802, electrode body AC803, ... electrode body AG807, electrode body AH808, electrode body AJ809, electrode body AK810, electrode body AL811, electrode body AM812, electrode body AN813, and electrode body AP814, and the electrode bodies 53 arranged on the electrode belt RB82 are referred to as electrode body BA821, electrode body BB822, electrode body BC823, ... electrode body BG827, electrode body BH828, electrode body BJ829, electrode body BK830, electrode body BL831, electrode body BM832, electrode body BN833, and electrode body BP834. In the figure, the electrodes AG807 to AP814 and the electrodes BG827 to BP834 are located in positions that cannot be shown, for example, on the back of the hand of the forearm, so they are omitted from the illustration. The electrode belt RB82 is wrapped around the elbow side of the forearm. The thickness of the part of the forearm close to the elbow is thicker than that of the wrist side, so the electrode frame 52 is longer than the electrode belt RA81, and the sizes of the electrodes BA821, BB822, BC823, ... and BP834 may be larger than the electrodes AA801, AB802, AC803 ... and AP814 of the electrode belt RA81, and for example, the width of the electrode 53 may be about 30% larger. This level of size difference can minimize both the risk of applying an electric signal to multiple motor points with one electrode and the risk of not being able to use the motor points well due to the presence of motor points between the electrodes, thereby improving the efficiency of the entire training. By making the electrode body placed on the electrode belt worn closer to the elbow larger than the electrode body placed on the electrode belt worn on the wrist side, it is possible to identify or detect and use all motor points without increasing the number of electrodes used, and the efficiency of training can be improved or not reduced. If the electrode body 53 used is extremely large, there is a possibility that an electrical signal will be applied to unintended motor points as mentioned above, but if the width of the electrode body 53 is increased by about 30% as in this embodiment, this possibility is minimized and is desirable.

Next, the elbow electrode 17 is attached to the elbow, and the cable C16 is connected to the output unit 12. The elbow electrode 17 may be a conductive adhesive pad. The electrode belt RA81 and the electrode belt RB82 are connected to the output unit 12 by the cable A14. The output unit 12 is further connected to the control unit 13 by the cable B15. The output unit 12 may be connected to, for example, a household outlet by a power cord to supply power. In this embodiment, for example, an AC adapter is connected to the outlet, and DC 12V from the AC adapter is supplied to the output unit 12. The output unit 12 also supplies a portion of the supplied power to the control unit 13 by the cable B15. However, the control unit 13 may also be supplied with power by a separate power cord. Alternatively, a battery may be arranged in the output unit 12, and a configuration without a power cord may be used. The battery may be a dry cell battery, or a secondary battery that can be repeatedly used by charging, such as a lithium-ion battery.

Figure 9 is an explanatory diagram of the output unit 12. Figure 9 shows the output unit 12 in (a) a top view, (b) a bottom view, (c) a front view, (d) a rear view, (e) a left side view, and (f) a right side view. The output unit 12 is supplied with power by a power cord connected to the power supply connection part 91. The elbow electrode connection part 92 is connected to a cable C16, which is electrically connected to the elbow electrode 17. The control unit connection part A93 is connected to a cable B15, which enables communication with the control unit 13. The output A94 and the output B95 are each connected to one cable B15, which is connected to the electrode belt R24 (electrode belt RA81 and electrode belt RB82) and the electrode belt L27, etc. The power button A96 controls the ON/OFF power supply of the output unit 12. The display unit A97 displays various information necessary for operating the training device 1, such as the settings of the output unit 12, the output state, or the communication state with the control unit 13. The display unit A97 may be configured using, for example, a liquid crystal panel or an EL panel. In this embodiment, the display unit A97 also functions as a touch panel and also serves as an operating means for the output unit 12. This allows the display unit A97 to be used to set the electrical signal described below and the training time. When the output button A912 is pressed, an electrical signal described below is supplied, and when pressed again in this state, the electrical signal stops. The UP button 98 and DOWN button 99 are used to adjust the amplitude of the electrical signal to be output. The UP button 98 is used to increase the output of the electrical signal, and the DOWN button 99 is operated to decrease the output.

Figure 10 shows the control unit 13. Figure 10 shows the control unit 13 in (a) a top view, (b) a bottom view, (c) a front view, (d) a rear view, (e) a left side view, and (f) a right side view. The display unit B101 displays the settings of the output unit 12, the output state, the communication status with the output unit 12, and other various information necessary for operating the training device 1. The display unit B101 may be configured using, for example, a liquid crystal panel or an EL panel. In this embodiment, the display unit B101 also functions as a touch panel and also serves as an operating means for the control unit 13. This allows the display unit B101 to be used to perform various settings and operations such as the settings of electrical signals and training time, which will be described later. The power button B102 controls the ON/OFF of the power of the control unit 13. The output unit connection unit B103 is connected to a cable B15 and communicates with the output unit 12 to control the output unit 12.

Figure 11 shows a block diagram of the output unit 12. The output unit 12 is configured to include at least some or all of the control unit A1103, user IF unit A1102, waveform generation unit 1101, power supply unit A1106, storage A1107, timer A1104, communication unit A1105, etc. The waveform generation unit 1101 has a total of 28 outputs, CH1 to CH14, CH21 to CH34, and the output of CH1 is connected to, for example, electrode AA801, CH2 to electrode AB802, CH3 to electrode AC803, ... CH14 to electrode AP814, and similarly, the output of CH21 is connected to, for example, electrode BA821, CH22 to electrode BB822, CH23 to electrode BC823, ... CH34 to electrode BP834 via cable B15 or the like, so that an electrical signal can be supplied individually to each electrode.

The control unit A1103 has a built-in interface unit for connecting with each unit in addition to a CPU and memory, and controls the output unit 12. The memory stores various parameters related to the output electrical signal, such as the frequency and pulse width. In this embodiment, the memory is described as being located in the control unit A1103, but is not limited to this and may be provided outside the control unit 402. Furthermore, the memory may be a non-volatile semiconductor memory, or may be configured as a removable and easily rewritable storage medium such as an SD card, allowing various parameters of the electrical signal to be freely rewritten for use.

The output unit 12 is provided with a storage A1107, which may also store information about the electrical signal output from the output unit 12, such as various parameters such as the frequency and pulse width of the electrical signal to be output, information about motor points to be described later, information about training, and information about the user. In this embodiment, the storage A1107 is described as being located in the output unit 12, but this is not limited to this and may be located outside the output unit 12. Furthermore, the storage A1107 may be a non-volatile semiconductor memory, or may be configured as a removable and easily rewritable storage medium such as an SD card, and may be configured to freely rewrite various parameters of the treatment waveform and user information for use. The communication unit A1105 exchanges information about electrical signals such as various parameters, information about motor points, information about training movements, or information about the user with the control unit 13 via the cable B15.

The user IF unit A1102 is connected to the display unit A97, power button A96, UP button 98, DOWN button 99, and output button A912, and acquires information indicating that the user has operated these buttons, and notifies the control unit A1103 of the content of the user's operation. Furthermore, the user IF unit A1102 instructs the display unit A97 to notify the user of the necessary information according to instructions from the control unit A1103.

The power supply unit A1106 converts the supplied power to match the power input specifications of each part, for example 5V or 12V, and supplies power to each part in a stable manner. Furthermore, this power may also be supplied to the control unit 13, or only a portion of this electrical power, for example 12V power, may be supplied to the control unit 13. In this embodiment, it is assumed that only 12V power is supplied to the control unit 13.

Figure 12 shows a block diagram of the control unit 13. The control unit 13 is configured to include at least some or all of the control unit B1203, the user IF unit B1202, the power supply unit B1206, the storage B1207, the communication unit B1205, the timer B1204, etc.

The control unit B1203 includes a CPU, memory, and an interface unit for connecting with each unit, and controls the output unit 12. The storage B1207 records information about the electrical signal output from the output unit 12, such as various parameters related to the electrical signal output, such as the frequency and pulse width, as well as information about the motor points (described later) and information about training. In this embodiment, the storage B1207 is described as being located in the control unit 13, but is not limited to this and may be provided outside the control unit 13. Furthermore, the storage B1207 may be a non-volatile semiconductor memory, or may be configured as a removable and easily rewritable storage medium, such as an SD card, and may be configured to freely rewrite various parameters of the electrical signal and user information for use.

The user IF unit B1202 is connected to the display unit B101 and the power button B102, and acquires information indicating that the user has operated these, and notifies the control unit B1203 of the content of the user's operation. Furthermore, the user IF unit B1202 instructs the display unit B101 to notify the user of the necessary information according to the instructions of the control unit B1203. The power supply unit B1206 converts the power supplied from the output unit 12 via the cable B15 to a voltage that matches the power input specifications of each unit, for example 5V or 12V, and supplies a stable supply of power to each unit. The communication unit B1205 exchanges information regarding electrical signals such as various parameters, information regarding the identification of motor points, and information regarding the user with the output unit 12 via the cable B15.

Figure 13 shows an electrical signal supplied to the human body. The horizontal axis indicates time, and the vertical axis indicates the amplitude of the current. The electrical signal is composed of a first signal that continues for time T1 and has an increasing amplitude, a second signal that follows the first signal and has a constant amplitude for time T2, and a third signal that follows the second signal and has a decreasing amplitude for time T3. If the electrical signal composed of the first, second, and third signals is called a fourth signal, the fourth signal is output every time T5, and is ultimately output repeatedly at time T5, in other words, repeatedly at cycles T5. The fourth signal may be output repeatedly immediately, or may be output after time T4 has elapsed from the third signal. In this case, the state from T1 to T5 is shown in Figure 13(a). If the fourth signal is output repeatedly without the off time T4, T4=0 may be set. Figure 13 shows the electrical signals used in an easy-to-understand manner, and each electrical signal is composed of several pulses, but in reality, more pulses than those shown in Figure 13 may be output. Furthermore, the electrical signal used is not limited to a square pulse as shown in FIG. 13, but may be a triangular wave, a sine wave, a step wave, an impulse train, etc., as long as it is possible to reliably control the frequency and the amplitude, such as increasing the amplitude, keeping the amplitude constant, or decreasing the amplitude. Note that while FIG. 13 shows the current value as the vertical axis, this is not limited, and control may be performed using the voltage value.

Furthermore, the electric signal may be a bipolar electric signal as shown in FIG. 13(a), a unipolar negative electric signal as shown in FIG. 13(b), or a unipolar positive pulse. In this embodiment, a negative pulse as shown in FIG. 13(b) is used. That is, it shows an electric signal output by the output unit 12 and supplied to the human body via the electrode body AA801 and other electrode bodies 53 arranged on the electrode belt RA81, etc. The first and third signals are not limited to changing as shown in FIG. 13, and may change their amplitude linearly at a constant rate over time, change nonlinearly, or be controlled in a stepped or step-like manner. The electric signal flows between each electrode body 53 and the elbow electrode 17.

The method of using the training device 1 will now be described. The electrode pad 51 is attached, for example, to the electrode belt RA81 or electrode belt RB82, and the brace 11 is attached to the forearm as shown in FIG. 8. The electrode belt RA81 or electrode belt RB82 is then connected to the output unit 12 via a cable A14. For example, the electrode belt RA81 is connected to output A94, and the electrode belt RB82 is connected to output B95, both of which are connected to the output unit 12. The elbow electrode 17 is attached to the elbow, and is then connected to the output unit 12 via a cable C16. The output unit 12 and the control unit 13 are connected to each other via a cable B15.

When the power button B102 and power button A96 are pressed to turn on the control unit 13 and output unit 12, that information is sent by the user IF section B1202 and user IF section A1102 to the control section B1203 and control section A1103, respectively, and the control section B1203 and control section A1103 light up the display section B101 and display section A97 to notify the user that the power has been turned on.

First, the user operates the display B101 of the output unit 12 to set the parameters of the electrical signal to be used. The parameters of the electrical signal include T1 to T5 in FIG. 13, the pulse frequency, and the pulse width. For example, T1 and T3 can be set to values between 0 and 3 seconds, T2 to values between 0.5 and 30 seconds, and T4 to values between 0 and 30 seconds. In this embodiment, T1 is set to 0.5 seconds, T2 to 5 seconds, T3 to 1 second, and T4 to 4.5 seconds, and other parameters such as a pulse width of 100 μsec and a frequency of 100 Hz are used. It is recommended that these parameters be changed as appropriate depending on the user's sensitivity to electrical signals and their perception of pain.

Figure 14 shows the screen of the control unit 13 used to identify motor points. When using the training device 1 for the first time, the motor points of each finger are identified first. The display unit B101 displays an electrode number display 1401, an output display 1402, an electrode number change display 1403, an output change display 1404, an output control display 1405, and a registration display 1406, as shown in Figure 14(a).

Pressing "Plus" on the electrode number change display 1403 increases the electrode number by one, and pressing "Minus" decreases it by one. This allows one electrode body 53 to be selected for use in identifying the motor point. Similarly, pressing "Plus" on the output change display 1404 increases the amplitude of the current output to the selected electrode body by 1 mA, and pressing "Minus" decreases it by 1 mA. This controls the strength of the current output to the electrode body used to identify the motor point. The amplitude value of the output current is displayed on the output display 1402. Note that the output displayed or controlled here is the amplitude of the second signal in FIG. 13.

When the output control display 1405 is pressed, output is started, but the current value immediately after the output control display 1405 is pressed is set to the initial value of 0 mA or a very weak current value, for example, 1 mA. In this embodiment, 1 mA is set as the initial value. When the output control display 1405 is pressed, the output change display 1404 becomes active, and output control becomes possible. When the output control display 1405 is pressed again, output stops. Note that when the output control display 1405 is pressed, the number of the electrode body with the smallest number is displayed. In this embodiment, for example, 801 for electrode body AA801 is displayed. Other numbers, for example, serial numbers 1 to 28, may be associated with electrode bodies AA801 to BP834, and for example, 1 may be displayed instead of 801, 2 may be displayed instead of 802, 3 may be displayed instead of 803, ..., for example, 15 may be displayed instead of 821, for example, 16 may be displayed instead of 822, ..., for example, 28 may be displayed instead of 834.

The user first presses the output control display 1405. Immediately afterwards, the electrode 53 with the smallest number, for example electrode AA801, is selected and 801 is displayed, so the output change display 1404 is controlled for that electrode AA801 to gradually increase the output. If there is no movement such as bending or extension in any of the fingers, the user presses the "plus" on the electrode number change display 1403 to select the next electrode, for example electrode AB802. If a new electrode is selected and the display on the electrode number display 1401 is changed, that is, if the electrode number change display 1403, which is the means for selecting the electrode 53, is operated, the output is set to the above-mentioned initial value of 1 mA and output.

The output is gradually increased using the output change display 1404 for a new electrode, for example electrode body AB802, and observations are made to see if there is any movement in any of the fingers. For example, if there is movement in the fifth finger, for example bending, at an output of -10 mA, this indicates that there is a motor point in the area of the electrode used, in this case electrode body AB802, that is causing bending in the fifth finger. The user presses the registration display 1406 to register this information.

Figure 14(b) shows the display used to register the motor point. For example, a display corresponding to each finger is displayed, such as the fifth bend display 1410 corresponding to the fifth finger. In this display, the first finger bend display 1411 is displayed for the first finger, the second finger bend display 1407 is displayed for the second finger, the third finger bend display 1408 is displayed for the third finger, the fourth finger bend display 1409 is displayed for the fourth finger, the fifth finger bend display 1410 is displayed for the fifth finger, and the wrist bend display 1412 is displayed for the wrist fingers. When registering a motor point, by pressing "Bend" or "Extend" in the bend display for each finger, the fact that the electrode body is placed at the motor point, that bending or extending can be given, and the amplitude of the required electrical signal are registered. In the above example, that is, the fifth finger is bent with -10 mA to the electrode body AB802, so by pressing "Bend" in the fifth bend display 1410, it is registered that the fifth finger is bent by passing -10 mA to the electrode body AB802. If the fifth finger is extended by applying minus 10 mA to the electrode AB802, pressing "extension" on the fifth bend display 1410 registers that the fifth finger will be extended by applying minus 10 mA to the electrode AB802. Pressing the first bend display 1411, the second bend display 1407, the third bend display 1408, the fourth bend display 1409, or the fifth bend display 1410 automatically returns the screen to FIG. 14(a). Furthermore, when the display returns to that of FIG. 14(a), the electrode number may be automatically advanced by one, and the output value may also be reset to an initial value. Such a setting that automatically returns the electrode number and output value to an initial value can simplify the operation related to the identification of the motor point, which ultimately improves the efficiency of training. In this way, the motor point identification task is applied to all 28 electrodes, thereby identifying the motor points for all fingers. If motor points for all fingers cannot be adequately identified, the positions of the electrode belt RA81 and the electrode belt RB82 are shifted forward or backward to attempt to identify the motor points again. In the training device 1 of the present invention, by shifting the electrode belt RA81, etc., forward or backward, motor points can be identified over the entire forearm without changing the number or size of the electrodes, and the motor points can be reliably identified and used for training, improving the efficiency of training.

In each screen such as that shown in FIG. 14, a menu 1414 is displayed, and pressing the menu 1414 can switch to the screen shown in FIG. 14(a) or FIG. 14(b), a screen for setting parameters for electrical signals, or a screen used for training, which will be described later.

Figure 15 shows an example of information related to identified motor points. The information is stored in storage B 1207 or storage A 1107 of the control unit 13 or output unit 12. The results of identifying such motor points may vary depending on the user, or even for the same user depending on the level of training, so it is necessary to redo the identification of motor points every time a new user of the training device 1 is used, or periodically. Note that in this embodiment, the electrical signal used is a unipolar signal of negative polarity as shown in Figure 13(b), so the numbers indicate negative amplitude.

Figure 16 shows a screen used for training using the motor points identified in the above manner. This screen displays a first action display 1601, a second action display 1602, a third action display 1603, a count display section 1604, and a count setting section 1605. The first action display 1601, the second action display 1602, and the third action display 1603 are assigned the actions of rock, paper, and scissors, respectively. When the user selects one and presses one of the display sections, the pressed display section is inverted to indicate that the action has been selected. For example, if rock is selected, the user presses the first action display 1601, and the color of the first action display 1601 is inverted to indicate that rock has been selected. When the first action display 1601 is pressed, for example, 5 is displayed in the count display section 1604. When the plus in the count setting section 1605 is pressed, the count is displayed one by one, that is, 6, 7, 8, .... This display indicates the number of times the selected action is to be repeated. For example, when the color of the first action display 1601 is inverted and 7 is displayed in the number of times display section 1604, this indicates that training will be performed in which the rock action assigned to the first action display 1601 is repeated seven times. Once the action and number of times have been set, pressing the OK button 1606 causes this information to be saved in storage A 1107, or in storage A 1107 and storage B 1207.

In FIG. 16, three types of actions are displayed, but the present invention is not limited to this, and four or more types of actions may be displayed and selected. Furthermore, although the present invention is not limited to this, the present invention may be configured so that only one type of action can be set, but the present invention is not limited to this, and two or more actions may be selected and set.

When the motor points have been identified and their operation settings have been completed, press the power button B102 to turn off the control unit 13, and disconnect the cable C16 to disconnect the control unit 13 from the output unit 12. When the connection is disconnected, the display A97 of the output unit 12 changes.

Figure 17 shows the switched display of the display unit A97. As shown in Figure 17, an action display 1701 showing the selected action, a training count display 1702, and a training time display 1703 are displayed. When the output button A912 is pressed, an electrical signal that gives the set action to the fingers is output to the selected electrode. The action display 1701 only needs to show what the training action is, and if the selected action is "rock", the character "rock" may be displayed, or an image of a rock may be displayed, or an animation or video of the fingers bending to make a rock may be displayed repeatedly.

Figure 18 shows information about the electrical signal that provides the selected movement (information about the training movement), and indicates the channel and amplitude value of the electrical signal output to each electrode 53. Now, since the rock movement is set, the waveform generating unit 1101 selects the electrode number that provides the flexion of each finger and the current value of the electrical stimulation from Figure 15. The output channel number of the waveform generating unit 1101 that applies the electrical signal to each electrode is also specified by specifying the electrode body. For example, since the first finger is flexed for the rock movement, the electrode body BF826 that provides the flexion of the first finger is selected from Figure 15, and the current amplitude value minus 10 mA is set to CH26 to which the electrode body BF826 is connected. Similarly, the channel that provides the flexion of each finger and the amplitude of the electrical signal are set, and these are summarized as Figure 18. In this embodiment, the output unit 12 that receives information about the motor points in Figure 15 and information about the movement and number of times used in training from the control unit 13, specifically the control unit A1103, performs the setting as shown in Figure 18. Alternatively, the control unit 13, specifically the control unit B1203, may be configured to make settings as shown in FIG. 18 and send the information in FIG. 18 to the output unit 12, and the output unit 12 may output an electrical signal to each electrode based on that information.

Before training begins, the training count display 1702 displays the number of trainings set by the control unit 13, for example, 7. When the number of trainings is set, an electrical signal is output every T5, so the training time is determined according to the set value of T5, and the total training time is displayed on the training time display 1703. In this embodiment, T1 is set to 0.5 seconds, T2 is set to 5 seconds, T3 is set to 1 second, and T4 is set to 4.5 seconds, so T5 is set to 12 seconds, and this is repeated 7 times, so the total training time is displayed as 84 seconds. When the output button A912 is pressed, the fourth signal is output from each channel to the forearm by the electrode body according to the preset parameters as set in FIG. 18. Each time the fourth signal is output once, the number displayed on the training count display 1702 decreases by one, and the training time display 1703 also decreases by T5, and when the training count and training time reach zero, the output is stopped.

During training, if the strength of the electrical signal being output, i.e., the output, is weak or strong, the amplitude of the electrical signal can be adjusted using the UP button 98 or DOWN button 99. Pressing these buttons once increases or decreases the amplitude of the electrical signal by 0.5 mA. For example, each time the UP button 98 is pressed once, the amplitude of the second signal of the electrical signal being output from the waveform generating unit 1101 increases by 0.5 mA, and each time the DOWN button 99 is pressed, it decreases by 0.5 mA.

In this embodiment, rock is used as the motion used for training, but when changing the motion for training from rock to another motion, for example, paper, the following is performed. First, the control unit 13 and the output unit 12 are connected with the cable B15, and the power of the control unit 13 is turned on by the power button B102. Next, the information of FIG. 15, which is information regarding the motor points, is read from the output unit 12. If the information is stored in the control unit 13, that information may be used. Next, the motion to be used for training is selected by the control unit 13 using the display of FIG. 16. Now, when selecting rock as the motion, the third motion display 1603 is pressed as above, and further the number of times is set by the number of times setting unit 1605, and the OK button 1606 is pressed, and the information regarding the selected motion is transferred to the output unit 12. When the information regarding the electrical signal that provides the selected motion, as shown as an example in FIG. 18, is generated by the output unit 12, the control unit 13 does not need to read the information regarding the motor points as in FIG. 15 from the output unit 12, and it is sufficient to transfer the selected motion and the number of times to the output unit 12. On the other hand, when the control unit 13 generates information about the electrical signal that provides the selected action, the control unit 13 reads out information about the motor points as shown in FIG. 15 from the output unit 12, or when the control unit 13 holds information about the motor points, it uses that information to generate information about the electrical signal that provides the selected action, the paper movement, and transfers it to the output unit 12. After that, the paper movement is trained by the output unit 12 in the manner described above.

The electrode belt RA81 and electrode belt RB82 used in this embodiment may be just the right length for an adult male, but may be too long for a child or woman. In this case, the electrode belt R24 may be used by removing a part of the electrode body 53, such as the electrode body AP814 or the electrode body AN813, i.e., a part of the electrode body 53 may not be used. When the electrode body AP814 or the electrode body AN813 is removed and used, the electrode number 813 or 814, which is the number of the electrode body AP814 or the electrode body AN813 that is not used, may be configured not to be displayed on the electrode number display 1401 even if the electrode number change display 1403 is operated in FIG. 14, in other words, the electrode number that is not used may not be displayed on the electrode number display 1401 even if the electrode number change display 1403 is operated. In other words, it may be configured so that settings for electrodes that are not used cannot be made. In this case, the user will not mistakenly have to identify motor points for electrode body AP814 or electrode body AN813 that are not being used, preventing a decrease in the efficiency of the entire training and improving the efficiency of the entire training.

Furthermore, prior to identifying the motor point, a weak current that cannot be detected by the user, for example 0.5 mA, may be output to all electrodes, and if the voltage value at that time is above a certain level, it may be determined that there is a problem with the contact between the electrode and the forearm, and the electrode with the problem may not be used. In this case, it may be configured so that the number of the problematic electrode cannot be set even if the electrode number change display 1403 in FIG. 14 is operated for that electrode. Alternatively, the number of the problematic electrode 53 may be displayed on display unit B101 or display unit A97, encouraging the user to reattach the electrode belt R24 or replace the electrode pad 51.

In the above embodiment, when training is performed, an electrical signal is output at regular time intervals, for example, at a cycle T5, to perform training, but the present invention is not limited to this. A separate switch that starts output may be provided, and training may be performed by operating the switch to output an electrical signal each time the switch is operated. This configuration is more preferable because training can be performed at the user's own pace. For example, the switch may be a separate switch display displayed on the display unit A97, which is operated with the opposite hand. Alternatively, a foot switch may be used and operated with the foot. In addition, in the case where the user controls whether or not to output an electrical signal, and an animation or video is displayed on the operation display 1701, the animation or video may start moving the fingers in accordance with the operation of the switch, that is, the animation or video may start playing. In addition, when the control unit 13 and the output unit 12 are connected, the output unit 12 cannot control the output of electrical signals. For example, the output button A912, the UP button 98, and the DOWN button 99 can be disabled, or only the output button A912 can be disabled. This can prevent electrical signals from being output unintentionally by the user due to erroneous operation of the output unit 12.

In this embodiment, the value of the information on the motor points is used as the current value used for training. For example, when paying attention to the current value in the information on the electrical signal that provides the selected motion (information on the training motion) as shown in FIG. 18, the current that provides flexion to the first finger is set using 10 mA, which is the current value of electrode number 826 in the flexion of the first finger in FIG. 15, and the same is true for the other fingers. The present invention is not limited to this, and the amplitude of the electrical signal used in the information on the training motion exemplified by FIG. 18 may be determined by a determination method based on the information on the motor points. For example, the information on the training motion as shown in FIG. 18 may be created by subtracting a certain value, for example 1 mA, from the current value that provides flexion or extension of each finger, which is information on the motor points. In this case, the current values for providing flexion in the information on the motor points are 10 mA, 5 mA, 11 mA, 7 mA, and 10 mA, respectively, so 1 mA may be subtracted from each of these to set 9 mA for the first finger, 4 mA for the second finger, 10 mA for the third finger, 6 mA for the fourth finger, and 9 mA for the fifth finger as information on the training motion. The method of setting the information on the training motion is not limited to this, and may be determined using a certain coefficient, for example, 0.8. In this case, the current values for providing flexion in the information on the motor points are 10 mA, 5 mA, 11 mA, 7 mA, and 10 mA, respectively, so 0.8 may be multiplied to set 8 mA for the first finger, 4 mA for the second finger, 8.8 mA for the third finger, 5.6 mA for the fourth finger, and 8 mA for the fifth finger as information on the training motion. Furthermore, the information on these training motions may not use one value for each finger, but may change the above-mentioned certain value or certain coefficient depending on the finger. Furthermore, while the above method of determination was to make the current value in the information related to the training movement smaller than the current value in the motor point information, a method of determination that makes it larger on the other hand, such as adding a constant value, dividing by a coefficient smaller than 1, or multiplying by a coefficient larger than 1, may also be used. During training, as described above, the supply of electrical signals to each finger almost simultaneously can cause pain that was not felt when the motor points were identified or detected, so it is desirable to make the amplitude of the electrical signal used for the information related to the training movement smaller than the current value in the information related to the motor points.

In the above, it has been described that both the control unit 13 and the output unit 12 are set and used by the user, but the present invention is not limited to this, and for example, the control unit 13 may be set by a qualified person such as a doctor or physical therapist, and the trainee receiving the training may use the output unit 12. With the above-mentioned configuration, training can be efficiently carried out using the training device 1 that applies electrical signals to training, and the efficiency of the training can be improved directly or indirectly or as a whole.
The present invention is also characterized in that it provides an orthosis having a base, one or more fixing belts for fixing the base to the forearm, and an electrode belt having a plurality of electrodes arranged thereon, wherein the electrode belt is attached to the base by a fixing device, the base has an attachment part for attaching the fixing device, and the electrode belt has an orthosis that can change the relative position of the electrode belt with respect to the forearm by the attachment part and the fixing device.
Furthermore, the present invention is characterized in that the appliance is connected to an output unit, and the output unit outputs an electrical signal required for a specific electrode.
Furthermore, the present invention is characterized in that the output unit is connected to a control unit, which is used to supply electrical signals to the electrodes in order to identify motor points and the required electrical signals to be supplied to the motor points, and to identify the specific electrical signals and outputs required for the desired training.
