Hemiplegic forearm function recovery training device and method

Abstract

A hemiplegic forearm function recovery training device includes a forearm mounting part () on which a forearm (S) is to be mounted. The forearm mounting part () includes a mounting body (), an inner frame portion (B), an outer frame portion (A), and a control part. The mounting body () has a forearm fixing portion () on which the forearm (S) is mounted and a gripping mechanism () capable of being gripped by a hand of the forearm (S). The inner frame portion (B) is fitted to the mounting body () and is rotatable around the forearm (S). The outer frame portion (A) guides the inner frame portion (B) in a rotation direction thereof. The control part performs a series of controls that repeatedly causes normal rotation, stop, reverse rotation, and stop of the inner frame portion (B) while acquiring rotation angle information of the inner frame portion (B). In the normal rotation the control part controls angular velocity or acceleration of the inner frame portion (B) to stimulate a training target muscle of the forearm (S) and in the reverse rotation the control part provides resistance to the inner frame portion (B) to sustain stimulation to the training target muscle to maintain muscle tone.
