Motor imagery, function, and proprioception in people with below-elbow amputation who use myoelectric prostheses
Investigation of the Effect of Motor Imagery Ability on Upper Extremity Functionality and Proprioception in Transradial Amputees Using Myoelectric Prostheses
We will test whether people with a unilateral transradial amputation who use a myoelectric prosthesis differ from people without amputation in motor imagery ability and whether that ability relates to prosthesis function and limb position sense.

What this trial studies
This observational study compares adults with unilateral transradial amputation who have used a myoelectric prosthesis for at least six months to matched control participants. Participants must pass brief cognitive and mood screens and will complete motor imagery tasks, functional prosthesis tests, and proprioception measures. The study aims to relate motor imagery performance to functional prosthetic use and perceived limb position, drawing on hypotheses about cortical reorganization after amputation. No experimental intervention is applied; analyses will compare group performance and correlations between imagery ability and functional outcomes.
Who should consider this trial
Good fit: Adults 18–65 with a unilateral transradial amputation who have used a myoelectric prosthesis for at least six months, who are literate and pass cognitive and depression screening, are ideal candidates.
Not a fit: People who have bilateral amputations, use non-myoelectric prostheses, have major cognitive, neurological, psychiatric, or other physical problems, or cannot travel to the study site are unlikely to benefit from participating.
Why it matters
Potential benefit: If findings show a link between motor imagery ability and prosthesis function, they could guide rehabilitation and training to improve prosthetic control and body awareness.
How similar studies have performed: Motor imagery training has shown benefits in stroke, spinal cord injury, Parkinson’s disease, and some orthopedic conditions, but direct evidence in upper-limb amputees is limited and inconsistent.
