OYFM-7000 finger motion trainer can be controlled via an APP or remote control, enabling the user's hand to perform repetitive passive flexion and extension within a 0~70° range, thereby promoting rehabilitation for individuals with hand motor dysfunction. Simultaneously, the device uses sensors to collect electromyographic (EMG) signals from the user's upper limbs, performs feature recognition of the user's gestures, identifies hand movement intentions, and drives the motion components via a motor. This assists the user's hand in completing grasping motions, compensates for hand function, and to some extent, helps users achieve self-sufficiency in daily living.
