About

This observational study aims to compare myoelectric and bionic hands in terms of upper extremity function, body image and satisfaction.

The main questions it aims to answer are:

- Does upper extremity function differ between bionic and myoelectric hands?

• Individuals with unilateral upper limb amputation
• Regular use of a prosthetic device for at least 6 months
• Use of a semi-electronic elbow joint prosthetic component

Trial design

20 participants in 2 patient groups

Bionic Prosthetic Hand Group

Description:

Participants use advanced myoelectric prosthetic hands with multi-articulating structures and enhanced control features designed to improve functional performance.These devices are designed to enhance hand function, dexterity, and user interaction beyond conventional myoelectric control.

Myoelectric Prosthetic Hand Group

Description:

Participants in this group are individuals with upper limb amputation who use a myoelectric prosthetic hand controlled by surface electromyographic signals from residual limb muscles. These devices provide electrically powered hand movement and basic grasp functions without advanced bionic or sensor-integrated features.
