An interventional study of Condition A: Electrode Configuration and Condition B: Electrode Configuration in Prosthesis User, Prosthesis and Prosthetic, sponsored by Liberating Technologies, Inc.. Recruiting at 2 sites in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-07.
Sponsored by Liberating Technologies, Inc. · Not applicable, Interventional, and Basic science
This study is focused on optimizing methods for controlling upper-limb myoelectric prosthetic arms. If you are enrolled in this study you would be expected to visit one of the research sites for approximately 5 in-lab visits lasting about 4 hours. These visits are expected to happen within a 5-week period but may take longer depending on scheduling availability. During these visits you will be completing basic tasks similar to your everyday actions using a prosthetic arm that is provided for you.
5,056 studies on the registry are indexed under Wounds and Injuries; 861 are open to participants now.
This study's planned enrollment of 32 is below the median of 52 across 3,239 interventional studies indexed under Wounds and Injuries.

ACMC
The participant will complete a daily task (such as packing a suitcase) using their prosthetic arm. A study occupational therapist will score the participants ability along different metrics.
Time frame: Through study completion, an average of 1 month, 1 time at each 4 site visits.
Plan to share: Yes — Deidentified outcomes results for participants such as ACMC, clothespin relocation task, and virtual EMG measures.
