Description

The present invention is used, for example, in gait training (rehabilitation) for patients with foot paralysis due to cerebral infarction, gait training after orthopedic treatment by fracture, or gait training for elderly people, and the effects of gait training are numerically The present invention relates to a foot pressure measuring device to be evaluated and a foot pressure measuring method using the same.

For example, when a physical therapist gives walking guidance during recovery training for patients with foot paralysis, the physical therapist objectively determines whether the gait trainer is training as directed by the physical therapist. There is a problem that it is difficult to judge. For this reason, the results of gait training depend on the sensuous judgment of the physical therapist, and in particular, the judgment of the transition of the training step is often based on the empirical criteria of the physical therapist, and the objective judgment of the gait training result There is a need for quantitative criteria for In addition, there is a large difference in the contents of walking guidance among physical therapists, especially between new physical therapists and skilled physical therapists. There is a need for a device that can be used supplementarily to display the walking motion of a walking trainer quantitatively (objective result determination is possible).
In addition, when a physical therapist gives walking guidance during convalescent gait training after orthopedic treatment, there is a possibility that the fracture will recur if the treated foot is overloaded, but how to apply the load to the treated foot Depending on the case, there is a possibility that the foot load may exceed the allowable range in the recovery period, and there is a problem that it is difficult to determine the criteria for how to apply the load. For this reason, gait training is required so that a foot load exceeding an allowable range is not applied to the treated foot.

Therefore, as a device that can quantitatively display the walking motion of a gait trainer, a foot pressure measurement device that measures foot pressure during walking and displays it as a foot pressure distribution has been proposed. Here, the foot pressure measuring device is roughly divided into a fixed type in which a sensor for detecting foot pressure is installed on the floor that is like a walking path, and a movable type in which a sensor for detecting foot pressure is attached to the bottom of footwear such as shoes. However, when gait training is performed, the degree of freedom of assistance when the physical therapist assists the trainee is high, that it is easy to secure a fixed length of the walking path, and aids such as handrails A movable foot pressure measuring device is used from the viewpoint that it is difficult to be restricted by the installation of the foot. In a movable foot pressure measuring device, a sensor that detects a foot pressure is generally incorporated in an insole of a shoe (see, for example, Patent Document 1 and Non-Patent Document 1).

The left electrical component 25 (the same applies to the right electrical component 26) is configured to convert an analog signal from each of the left load sensors 13 to 20 transmitted through the signal line 23, that is, an analog left load signal into a digital signal, That is, it has pressure distribution data conversion means 33 which is an example of an A / D converter for converting into a digital left load signal. In the pressure distribution data conversion means 33, for example, when each analog left load signal from the load sensors 13 to 20 is input via the signal line 23, for example, the load sensor 13, the load sensor 14,. In the order of the load sensor 20, the analog left load signal is converted into the digital left load signal, and the formation of the left digital signal group composed of the digital left load signals is repeated.

The filter means 34 and the pressure distribution data storage means 35 are each equipped with a program for removing noise from the left load information and a program for saving the left load information subjected to the noise removal processing. Can be configured.

As shown in FIG. 5, the monitor unit 29 receives the left and right load information transmission signals transmitted from the left and right electrical components 25 and 26, and forms the left and right load information reception signals. And a pressure distribution data storage means 36 that combines left and right load information output from the receiver 28 and stores them as load information for walking. In addition, the monitor unit 29 sequentially extracts the walking load information stored in the pressure distribution data storage unit 36, and a plurality of specific parts set in advance in the left and right insoles 11 and 12, for example, left, A region P (hereinafter referred to as the thumb part P) where the thumb is in contact with the front side of the right insole 11 and 12, a region Q (hereinafter referred to as the little finger part Q) where the little finger is contacted, a region R (hereinafter referred to as the finger part Q) , Heel region R), region S corresponding to the arch (hereinafter referred to as arch region S), and time T of the load value applied to the region T outside the arch (hereinafter referred to as outer region T) Each load value in a specific part selected from a plurality of specific parts, for example, the thumb part P, the little finger part Q, the heel part R, and the outer part T is sequentially output (with time). Along with the load value of the selected specific part That is, each time the load values in the thumb part P, the little finger part Q, the heel part R, and the outer part T reach a preset value, an arrival detection signal is output, and when walking ends, for example, , Pressure distribution data display control means 37 for calculating the average value of the load values at the thumb part P, the little finger part Q, the heel part R, and the outer part T and outputting the results.

Furthermore, the monitor unit 29 displays a display 38 (see FIG. 1B) that displays the time change of the load value for each selected specific portion output from the pressure distribution data display control means 37 as the load change of the sole. ) And sound data storage means 39 for outputting a sound forming signal corresponding to a preset sound in response to each arrival detection signal output from the pressure distribution data display control means 37, and output from the sound data storage means 39 Sound data reproducing means 40 for outputting an analog signal of sound corresponding to the generated sound forming signal, and a speaker 41 for generating sound from the analog signal of sound from the sound data reproducing means 40.

Here, the pressure distribution data storage means 36 combines the left and right load information output from the receiver 28 and stores it as the load information for walking, and the pressure distribution data display control means 37 is selected. Each load value of the specific part is sequentially acquired and output from the pressure distribution data storage means 36, and an arrival detection signal is output every time the acquired load value of each specific part reaches a preset value. When the program is completed, it can be configured by installing a program for calculating an average value of the obtained load values of each specific part and outputting the result, in each microcomputer. Thereby, the monitor unit 29 can be a dedicated portable terminal.

Further, the sound data storage means 39 stores a digital signal of sound informing that the load values of the selected specific parts have reached a preset value together with the corresponding arrival detection signal, and the arrival detection signal is received from the outside. A program that outputs a digital signal of a corresponding sound when it is input can be configured by installing in a microcomputer. Further, the sound data reproducing means 40 is configured using, for example, a D / A converter that converts a digital signal of sound output from the sound data storage means 39 into an analog signal and an amplifier that amplifies the analog signal.

From the characteristics of walking, the left and right load information is a collection of intermittent left and right digital signal groups in terms of time, and the right digital signal in the time zone where the left digital signal group exists. There is no group, and the left digital signal group does not exist in the time zone in which the right digital signal group exists. For this reason, the load information of a walk is comprised by arranging the left and right load information output from the receiver 28 in order. The order of the digital left and right load signals constituting the left and right digital signal groups is determined by the pressure distribution data converting means 33 by converting the analog left and right load signals from the load sensors 13 to 20 into pressure distribution data conversion means 33. Corresponds to the order of digital signals.
Therefore, by extracting the load signals corresponding to the load sensor 13, the load sensor 14,..., The load sensor 20 from the load signals constituting the left and right digital signal groups, the load sensors 13 It is possible to reproduce the time change of the load value respectively detected at -20, and by superimposing these, the load change of the sole during walking can be obtained.

For example, the time change of the load value applied to the thumb part P during walking is the change of the load detected by the load sensors 13 and 14 respectively. Further, the time change of the load value applied to the little finger part Q is an overlap of the load changes detected by the load sensors 15 and 16, respectively, and the time change of the load value applied to the outer part T is the load value detected by the load sensor 20. The change and the time change of the load value applied to the heel region R are superimposed on the load changes detected by the load sensors 17 and 18, respectively. Therefore, the load values applied to the thumb part P, the little finger part Q, the heel part R, and the outer part T are determined in advance from the changes in the load values applied to the thumb part P, the little finger part Q, the heel part R, and the outer part T. It is possible to determine whether or not the set value has been reached.

Next, a foot pressure measuring method using the foot pressure measuring device 10 according to the first embodiment of the present invention will be described.

And as shown to FIG. 1 (A), (B), FIG. 3, several in the range of the toe part from the buttocks of the left and right insoles 11 and 12 with which it attaches to the shoes which a walk trainer uses. The load sensors 13 to 20 are distributed and analog signals output during walking from the load sensors 13 to 20 arranged on the left and right insoles 11 and 12, respectively, are applied to the left and right ankles of the walking trainer. The left and right electrical components 25 and 26 attached to the digital signals are converted into digital signals, and the load information formed from the obtained digital signals is transmitted to the transmitters 24 provided on the left and right electrical components 25 and 26, respectively. The transmission signal is converted into a wireless transmission signal via the receiver, and the transmission signal is received by the receiver 28 provided in the monitor unit 29 attached to the lower left arm of the physical therapist to form a reception signal, Multiple specific parts set in advance in the insole 11, 12 from the received signal For example, the time change of the load value applied to the thumb part P, the little finger part Q, the heel part R, the arch part S, and the outer part T is obtained and displayed on the display 38 of the monitor unit 29 as the load change of the sole. Each time the load value applied to the selected thumb part P, little finger part Q, heel part R, and outer part T reaches a preset value, a sound is generated from the speaker 41 provided in the monitor unit 29. Yes. Details will be described below.

The left and right insoles 11 and 12 provided with load sensors 13 to 20 are attached to shoes used by the walking trainer, and the left and right electrical parts 25 and 26 are attached to the left and right ankles of the walking trainer. On the other hand, the monitor unit 29 is attached to the lower left arm of the physical therapist who gives walking guidance. Then, the physical therapist operates an operation panel (not shown) of the monitor unit 29 to obtain the thumb part P, the little finger part Q, the heel part R, the arch part S, and the outer part T obtained by the pressure distribution data display control means 37. It is set so that the change over time of the load value applied to each is displayed on the display 38. When the gait trainer starts gait training under the guidance of the physical therapist, for example, by stepping on the left foot, the heel region R of the left sole is first grounded, and then the outer region T, the little finger region Q, The thumb part P is sequentially grounded. When the heel part R, the outer part T, the little finger part Q, and the thumb part P are grounded, the weight of the gait trainer moves from the heel part R to the little finger part Q and the thumb part P, and the gait trainer moves to the right It becomes possible to step on. In walking training, the stepping action of the left and right feet shown above is repeated.

Therefore, as shown in FIG. 6, when the walking training is started (S-1), the monitor unit 29 starts to acquire walking load information formed in the pressure distribution data storage unit 36, and the load sensors 13, 14.

Then, it is determined whether or not the load value applied to the outer part T is greater than or equal to the set value (S-9). If the load value applied to the outer part T is greater than or equal to the set value, the load value applied to the outer part T is set. The arrival detection signal 2 indicating that the value has been reached is output (S-10). When the arrival detection signal 2 is output, the corresponding sound 2 digital signal is output in the sound data storage means 39, and the sound data reproduction means Sound 2 is generated from the speaker 41 through 40 (S-11). For this reason, the gait trainer can confirm that the movement of the body weight from the heel region R to the little finger region Q and the thumb finger region P according to the gait instruction of the physical therapist is executed. It can be confirmed that the gait trainer is performing the movement of weight according to the walking instruction.

Then, it is determined whether or not the load value applied to the little finger part Q is greater than or equal to the set value (S-14). If the load value applied to the little finger part Q is greater than or equal to the set value, the load value applied to the little finger part Q is set. The arrival detection signal 3 indicating that the value has been reached is output (S-15). When the arrival detection signal 3 is output, the corresponding sound 3 digital signal is output in the sound data storage means 39, and the sound data reproduction means Sound 3 is generated from the speaker 41 through 40 (S-16). For this reason, the gait trainer can confirm that the movement of the body weight to the little finger part Q according to the walking instruction of the physical therapist is executed, and the physical therapist follows the walking instruction of the walking trainer. It can be confirmed that the movement of weight is being performed.
