A body-powered prosthetic terminal device that improves grasping for people with upper limb amputation.
A Unique Body-Powered Terminal Device With Enhanced Grasping Capabilities for Individuals With Upper Limb Loss
This study will test a new body-powered prosthetic hook to see if it gives people with upper limb amputation stronger and more versatile grips than common commercial hooks.

What this trial studies
This interventional study will compare a novel body-powered terminal device against two commercial control hooks (light-spring and heavy-spring) in adults with upper limb amputation. Participants will perform standardized functional tasks and device demonstrations during in-person visits to measure performance and usability. Outcome measures will include grasp strength, task completion times, and safety/usability observations collected by study staff. The aim is to determine whether the new design eliminates the common functional tradeoffs seen in voluntary open body-powered devices.
Who should consider this trial
Good fit: Adults aged 18–80 with upper limb amputation who can speak English and can demonstrate safe and proper use of the terminal device are ideal candidates.
Not a fit: People with visual or cognitive impairments or with a history of neurological or musculoskeletal disorders, and those outside the 18–80 age range, may not benefit or be eligible.
Why it matters
Potential benefit: If successful, the device could give users stronger, more versatile grips and improved day-to-day function with a body-powered prosthesis.
How similar studies have performed: Body-powered hook prostheses are well-established clinically, but this specific enhanced-grip terminal device is novel and has limited prior clinical data.
