After tendon transfer surgery for upper limb motor dysfunction
Conditions
Interventions
Surface electrodes are placed on the skin overlying the muscle bellies of the flexor carpi radialis and flexor carpi ulnaris. To suppress wrist joint movement and avoid compensatory MP joint motion ca
s voluntary movement intention. Training is initiated after confirming the absence of abnormal movements or pain. Joint motion assistance is provided in synchrony with the voluntary movement intention

Inclusion criteria
Inclusion criteria: Individuals aged 20 years or older at the time of obtaining informed consent Patients in the chronic phase who have undergone tendon transfer surgery for upper limb motor dysfunction (finger MP joint extension impairment) and are at least 6 months postoperatively Patients with persistent upper limb motor dysfunction, including impaired finger MP joint extension, after tendon transfer surgery Patients who are medically judged by a physician to be eligible for training using the medical single-joint type Hybrid Assistive Limb (HAL) Individuals who fully understand the purpose and procedures of this study and have provided written informed consent of their own free will
Exclusion criteria
Exclusion criteria: Individuals with severe pain, skin disorders, wound infection, severe joint contracture, or other conditions at the HAL attachment sites (upper limb) that would prevent safe device application or training Individuals with severe cognitive impairment or psychiatric disorders that would make it difficult to understand the study procedures or comply with instructions Individuals with severe cardiovascular, respiratory, or neuromuscular diseases for whom exercise loading is medically considered inappropriate Individuals who plan to participate in other interventional studies during the study period Individuals who are otherwise deemed unsuitable for participation in this study by the principal investigator or co-investigators
