This single-center, prospective, comparative study aims to compare hand function, quality of life, patient satisfaction, task completion time, fatigue, and compensatory elbow, shoulder, and cervical movements in individuals with transradial amputation or wrist disarticulation who use either standard myoelectric or bionic hand prostheses. The primary research questions are:
1. Are there differences in patient satisfaction, quality of life, and hand function between individuals using standard myoelectric and bionic hand prostheses? 2. Do individuals using standard myoelectric and bionic hand prostheses exhibit different kinematics in terms of compensatory shoulder, elbow, and neck movements? Could bionic hand prostheses with their diverse grasping capabilities lead to fewer compensatory movements compared to standard myoelectric hand prostheses? 3. Can fatigue induced by performing specific activities of daily living alter hand function and upper extremity-neck kinematics in individuals using either standard myoelectric or bionic hand prostheses? 4. Can cognitive and physical fatigue following activities of daily living lead to different levels of changes in hand function and upper extremity-neck kinematics in individuals using standard myoelectric and bionic hand prostheses?
Having a transradial amputation or wrist disarticulation due to acquired or congenital causes,
Using a standard myoelectric or bionic hand prosthesis for at least 6 months,
Being between the ages of 18 and 65,
Having no neurological or cognitive disorders, rheumatic diseases, or other upper extremity dysfunction that could affect test results, and
Individuals younger than 18 or older than 65,
Those with additional musculoskeletal or neurological conditions preventing them from completing the tests and scales,
Those with psychiatric disorders or cognitive impairments preventing them from completing the questionnaire and assessment scales,
Those with stump or upper extremity conditions preventing them from using their prosthesis.
