Hand prosthesis usability and performance evaluation for people with upper limb absence

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This within-subject study compares a prototype hand to the participant's baseline device, focusing on user satisfaction, adoption, and functional performance. Eligible adults with transradial upper limb loss or congenital absence who already use a multi-articulating prosthesis participate at a sponsor site in Dublin, Ohio. Participants will try the prototype and report outcomes while their own device serves as a comparator. The study emphasizes real-world use and patient-reported outcomes to gauge usability.

Why it matters
