Compensatory Movements With Axon-Hook and Greifer in Transradial Amputees

France8 participantsStarted 2016-09-29

Plain-language summary

Upper limb amputees often report musculoskeletal pain due to exaggerated shoulder abduction movements. Previous studies on prosthetic hands showed that wrist orientation contributes to reduce shoulder compensatory movements. The hypothesis of this research is that prosthetic hooks may also provide better functional outcomes when offering wrist adjustments and a design that favors a good visualization of the grips. The objective of this study is to compare shoulder abduction, manual dexterity and satisfaction when using Axon-Hook and Greifer myoelectric hooks during repetitive tasks. Shoulder abduction and manual dexterity results are also compared with the sound side.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
