The control unit 39 of the device 1 controls the operation of the motor 13 based on items such as the exercise time set by the setting unit 36, and receives the signal from the sensor unit 29 and operates the electrical stimulation generator 5. Control.

  When the sensor unit 29 detects that the rotation shaft 13a of the motor 13 has been rotated to a preset rotation position, that is, the board 2 has moved to a predetermined movement position, a detection signal from the sensor unit 29 is detected. Is transmitted to the control unit 39. Upon receipt of the signal, the control unit 39 operates the electrical stimulation generator 5 instantaneously, and applies electrical stimulation by current pulses to the user M via the electrode 31.

  In the present embodiment, the timing of operating the electrical stimulation generator 5 is set at both end positions in the movement range of the boarding plate 2, that is, the end position on the side where the boarding plate 2 approaches the drive mechanism unit 3 (hereinafter, one predetermined position). ) And the end position on the side away from the drive mechanism unit 3 (hereinafter referred to as the other predetermined position). Of course, the electrical stimulation generator 5 may be configured to operate when the boarding board 2 moves to one of the predetermined positions.

  Next, the operation of the electrical stimulation combined exercise apparatus 1 will be described. Before starting the exercise, the cover 33 is opened, and the amplitude adjustment means 24 is used to set an amplitude suitable for the user M. The user M gets on the boarding board 2 while holding the holding member 35. A suitably selected number of electrodes 31 are attached to a place (lumbar region or lower limb) where electrical stimulation is to be applied. For example, when electrical stimulation is applied to the lower limbs, an appropriate number of electrodes 31 are attached to either the main muscle or antagonist muscle, or both the main muscle and antagonist muscle, and each muscle is electrically stimulated. Can be provided. In the present embodiment, when the boarding board 2 is moved to one predetermined position, electrical stimulation is applied to the quadriceps femoris muscle, which is the main muscle, via one electrode 31, 31, and when it is moved to the other predetermined position, it is antagonized. Electrical stimulation is applied to the hamstrings, which are muscles, via the other electrodes 31 and 31.

  The first output intensity setting unit 46 sets the current pulse intensity, and the exercise time setting unit 49 sets the exercise time. A motion start switch (not shown) provided in the operation unit 38 is pressed to operate the drive mechanism unit 3 to reciprocate the board 2.

  At the same time that the sensor unit 29 detects that the boarding board 2 has moved to one predetermined position and the other predetermined position, the electrical stimulation generator 5 is activated, and electrical stimulation is applied to the lower leg of the user M via the electrode 31. . When the boarding board 2 moves to one predetermined position, electrical stimulation is applied to the quadriceps femoris muscle, which is the main muscle, and when the boarding board 2 moves to the predetermined position, electrical stimulation is applied to the hamstrings, which are antagonistic muscles. According to the present embodiment, since electrical stimulation can be applied to the waist or lower limb of the user M in response to the movement of the boarding board 2, the waist or lower leg using both the reciprocating movement of the boarding board 2 and electrical stimulation by current. The slow and fast muscles can be stimulated, and the exercise effect can be further improved.

  When it is detected that an unillustrated timer built in the apparatus 1 has reached a set exercise time, the operation of the motor 13 is stopped by the control unit 39, and the movement of the board 2 is stopped. The user M descends from the boarding board 2 and moves while properly holding the grip portion 35b.

  In the above-described first embodiment, the example in which the sensor unit 29 is the encoder 30 has been described. However, the present invention is not limited to the encoder, and other means such as an optical sensor may be used. In short, any means may be used as long as the movement position of the boarding board 2 can be detected. Further, a stop button that can temporarily stop the electrical stimulation from the electrical stimulation generator 5 by the intention of the user M during the reciprocating movement of the boarding board 2 may be provided on the operation unit 38. Further, as an adjustment item related to the movement of the boarding board 2 other than the amplitude, for example, an inverter that varies the frequency of the power supplied to the motor is provided in the apparatus, and the rotational speed of the motor is controlled by the inverter to increase / decrease the boarding board. You may comprise so that a movement period (movement time) can be variably adjusted.

  In addition, when a user M such as an elderly frail person or a paralytic disease patient uses the device 1 and the knee board is broken due to the movement of the boarding board 2, the standing posture cannot be maintained on the boarding board 2. Control may be performed to change the output so as to increase the intensity of the electrical stimulation applied to the quadriceps side of user M as follows.

  That is, the knee flexion angle measuring means 51 measures the change related to the instantaneous knee joint flexion angle of the user M, and the control unit 39 calculates the change related to the knee joint flexion angle based on the measurement result. In addition, the change amount calculated by the control unit 39 (hereinafter referred to as “calculated change amount”) is compared with the change amount set by the change amount setting unit 50 (hereinafter referred to as “set change amount”). When it is detected that the amount has reached the set change amount or more, an electrical stimulus whose output has been changed to a high intensity is applied from the electrical stimulus generator 5 to the quadriceps muscle of the user M. By applying high-intensity electrical stimulation and contracting the quadriceps more effectively, it is possible to avoid a dangerous situation in which the user M falls on the boarding board 2 due to knee breakage, and can exercise safely. become. Hereinafter, the configuration and operation of changing the intensity of the electrical stimulation applied to the quadriceps muscle when the calculated change amount related to the knee joint flexion angle exceeds the set change amount will be described with reference to FIG.

  The knee flexion angle measuring means 51 is measured by a known analog knee joint angle meter 52 that can be mounted on the knee of the user M and that measures the flexion angle of the knee joint of the user M, and the knee joint angle meter 52. The AD converter 53 converts an analog signal related to the knee joint flexion angle into a digital signal. The digital signal converted by the AD converter 53 is input to the control unit 39.

  The set change amount related to the knee joint flexion angle is input into the control unit 39 via the change amount setting unit 50, and the calculated change amount calculated by the control unit 39 reaches the set change amount or more due to the occurrence of knee bending. In this case, the intensity of the electrical stimulation given to the user M is set by the second output intensity setting unit 48. The intensity of the electrical stimulation set by the second output intensity setting unit 48 is set higher than the intensity set by the first output intensity setting unit 47.

  The control unit 39 sequentially reads the measurement signal of the knee joint angle meter 52 digitized by the AD converter 53, and determines the knee joint flexion angle with the zero reference as the start of exercise (for example, immediately after the start of movement of the boarding board 2). The amount of change related to the bending angle is calculated from the bending angle of the knee joint during exercise (user M who is riding on the moving board 2), and the calculated change amount and change amount setting unit 50 The set change amount that has been set is sequentially compared. When the control unit 39 detects that the calculated change amount has reached or exceeded the set change amount, the control unit 39 applies electrical stimulation corresponding to the intensity set by the second intensity setting unit 48 to the quadriceps muscle of the user M. Control to give.

  At the start of exercise, the knee joint angle meter 52 is attached to at least one knee of the user M. During exercise, the knee joint angle meter 52 sequentially measures the flexion angle of the knee joint of the user M. If the control unit 39 detects that the calculated change amount related to the knee joint flexion angle is less than the set change amount when the boarding board 2 moves to one predetermined position, the first output intensity setting is performed. An electrical stimulus having an intensity corresponding to the intensity set by the unit 47 is output.

  When the control unit 39 detects that the calculated change amount related to the knee joint flexion angle is equal to or greater than the set change amount, the control unit 39, when the boarding board 2 moves to a predetermined position, The high-intensity electrical stimulation set by the output intensity setting unit 48 is changed and output. The quadriceps muscle is effectively contracted by the electrical stimulation changed and output with high strength, and the knee break of the user M can be suppressed, and the fall of the user M during the exercise can be prevented.

  When the calculated change amount related to the knee joint flexion angle falls below the set change amount due to the electrical stimulation applied to the quadriceps muscle of the user M, the intensity of the output of the electrical stimulation applied to the user M Is automatically changed to the intensity (weak intensity) set by the first output intensity setting unit 47 by the control unit 39.

  The change amount (calculation change amount) related to the knee joint flexion angle calculated by the control unit 39 is set as a change amount per unit time, and the user M exercises while slowly bending the knee on the boarding board 2 on which the user M moves. In addition, when the control unit 39 detects that the calculated change amount exceeds the set change amount, a high-intensity electrical stimulus is given to the user M, and at the same time, the safety of the user M In consideration of this, the operation of the motor 13 may be stopped and the movement of the boarding plate 2 may be stopped.

  In the second embodiment, the center-of-gravity movement detecting unit 40 detects the center-of-gravity movement of the waist that is induced by the reciprocating movement of the boarding board 2, and the control unit 39 controls the operation of the electrical stimulation generator 5 based on the detection result. It controls and gives an electric stimulus to the user M.

  Specifically, the center-of-gravity movement detection unit 40 is an acceleration sensor 41 that can be attached to the waist of the user M. The center-of-gravity movement amount setting unit 54 of the setting unit 36 sets a center-of-gravity movement amount as a threshold value as to whether or not to operate the electrical stimulation generator 5 in the control unit 39 in advance.

  The control unit 39 operates the electrical stimulation generator 5 to perform electrical stimulation when the amount of center of gravity movement obtained by integrating the output from the acceleration sensor 41 exceeds the amount of center of gravity movement set by the center of gravity movement amount setting unit 54. Grant to user M. Needless to say, the acceleration sensor 41 may be configured to be attached to an appropriate portion of the lower limb instead of the waist.

  Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 5 is a block diagram showing an electrical configuration of a main part of the electrical stimulation combined exercise apparatus 1 according to the third embodiment. In FIG. 5, the same or equivalent components as those in FIG. 2 are denoted by the same reference numerals, and the description of the components is omitted unless particularly required.

  In the third embodiment, a change in the surface myoelectric potential of the muscles of the lower limbs induced by the reciprocating movement of the boarding board 2 is detected, and the electrical stimulation generator 5 is operated based on the detection result to apply the electrical stimulation. It is.

  Changes in the surface electromyogram in the muscles of the lower limbs are detected by the myoelectric potential detector 42. Specifically, the myoelectric potential detection unit 42 is an electromyograph 43. A pair of myoelectric potential measuring electrodes 44 are attached to appropriate portions of the lower limbs of the user M, and the boarding board 2 is reciprocated while measuring the surface myoelectric potential between the electrodes 44. The measurement result of the surface electromyogram by the electromyograph 43 is sequentially input to the control unit 43.

  In the myoelectric change range setting unit 55 of the setting unit 36, a range related to a change in surface myoelectric potential that is a criterion for determining whether or not to activate the electrical stimulation generator 5 is set in the control unit 39. When the control unit 39 determines that the surface myoelectric potential of the lower limb muscle has changed beyond the range of surface myoelectric potential set by the myoelectric change range setting unit 55 due to the reciprocating movement of the boarding board 2, The stimulus generator 5 is activated to apply electrical stimulation to the user M. Of course, it is possible to measure not the surface myoelectric potential of the lower limb muscles but the change of the surface myoelectric potential of the lumbar muscles to apply electrical stimulation.

  It goes without saying that the present invention is not limited to the above-described first to third embodiments, and can be appropriately changed without departing from the spirit of the present invention.
