Hemiplegic forearm function recovery training device and method

Abstract

Provided is a hemiplegic forearm function recovery training device comprising a forearm mounting part (2) on which to mount a forearm (S), the forearm mounting part (2) comprising: a mounting body (20) comprising a forearm fixing part (22) on which to mount the forearm (S) and a grip mechanism (23) capable of being gripped with the hand of the forearm (S); an inner frame part (2B) capable of fitting with the mounting body (20) and rotating about the forearm (S); an outer frame part (2A) for guiding the inner frame part (2B) in the rotation direction thereof; and a control part for carrying outa series of control of, while acquiring rotation angle information relating to the inner frame part (2B), repeatedly carrying out normal rotation, stop, reverse rotation, and stop of the inner framepart (2B), controlling the angular velocity or acceleration of the inner frame part (2B) in the normal rotation so as to stimulate a training target muscle on the forearm mounting part (2), the training target muscle inducing muscle tone and stress reflex upon the muscle tone, and in the reverse rotation, imparting to the inner frame part (2B) resistance to sustain the stimulus to the training target muscle and maintain the muscle tone.

Description

technical field [0001] The invention relates to a training device and method for recovering the function of the hemiplegic forearm. Background technique [0002] In the event of a stroke, one of the left and right sides of the body may be left paralyzed. Paralysis left on one side of the left and right side of the body is called hemiplegia. With respect to this hemiplegia, some functions can be recovered through rehabilitation. This rehabilitation is performed by the hands of skilled doctors and therapists. However, since the training spans a long period of time, it puts a heavy burden on the body of doctors and therapists. Various training devices have been proposed for the purpose of eliminating this burden (for example, refer to Patent Documents 1 to 3). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2012-061101 [0004] Patent Document 2: International Publication No. 2014 / 092076 [0005] Patent Document 3: Japanese Patent Laid-Open No. 2016-101497 [0...

AI Technical Summary

Problems solved by technology

[0006] However, in the training devices disclosed in the above-mentioned Patent Documents 1 to 3, it is necessary to place the forearm on the device, but the shape and state of the forearm vary depending on the subject. Muscle atrophy and it is difficult to extend the wrist straight

Therefore, the work of placing the forearm on the device is very complicated, and since this work takes time, there is a concern that the efficiency of training will be reduced.
