What the trial is, and whether it could suit you

Upper limb amputation above the elbow results in a significant loss of function. There have been many advancements in surgery and prosthetic devices to restore arm function, but many people still reject upper limb prostheses. This is due to difficulties with how the socket fits and poor control of the device. Above-elbow prostheses are particularly challenging to use for several reasons. The socket must go all the way into the shoulder for stability. To hold the prosthesis onto the remaining arm, there needs to be a strap across the chest and shoulder. The prosthesis can be heavy, and the socket can slip or move around. This makes it hard to use muscle signals in the residual limb to control advanced prosthetic devices. People with limb loss are interested in advanced prostheses to use them reliably for day-to-day activities. Bone-anchored prostheses (BAPs) are a new approach. They are

📋 Eligibility rules (as published)
Inclusion Criteria: Individuals with transhumeral amputation who: 1. are between 18 and 65 years old, 2. have been scheduled to undergo osseointegration by the Alberta Limb Osseointegration Program. 3. demonstrate adequate pain-free shoulder range of motion to perform the required tasks and have potential muscle signals for myoelectric control to be able to undertake the muscle signal training 4. willing to undergo all of the study procedures and follow-up. Exclusion Criteria: Individuals who: 1. are unable to comply with treatment or follow-up processes, 2. are unable to understand English sufficiently to provide full informed consent. 3. have shoulder pathology on the side of the amputation (arthritis, adhesive capsulitis, chronic rotator cuff, or musculoskeletal dysfunction) that would negatively affect the ability to perform the training and functional assessments, 4. have insufficient muscle signals to operate a myoelectric prosthesis
