ClinConnect Summary

This clinical trial is studying a new way to help people who have lost their arm above the elbow (known as transhumeral amputation) regain better control and function of prosthetic devices. Many individuals face challenges with traditional prosthetics, such as discomfort and difficulty controlling the device. This trial focuses on using bone-anchored prostheses (BAPs) combined with a special surgery called Targeted Muscle Reinnervation (TMR) to improve muscle signal training. The goal is to see if these advanced approaches can make it easier for participants to use prostheses in their daily lives.

To be eligible for this trial, individuals must be between 18 and 65 years old, have a scheduled surgery for osseointegration, and have enough shoulder movement and muscle signals to participate in training. Participants will learn how to use their new device and will be monitored over time to evaluate how well it works for them. This trial is an important step in understanding how to improve the lives of those with upper limb loss and enhance their ability to perform everyday activities.

Eligibility criteria

• 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
