ClinConnect Summary

This clinical trial is studying how the length of the remaining part of the leg after an above-knee amputation affects muscle strength, balance, and overall ability to move. Researchers want to understand if the length of the residual limb and the strength of specific leg muscles influence how well someone can balance and perform everyday activities. This information could help improve rehabilitation and support for people with above-knee amputations.

People who might be eligible for this study are adults between 18 and 50 years old who have had an amputation above the knee on one leg, have been walking with a prosthetic leg for at least six months, and do not have other health issues that affect balance or muscle strength. If you join the study, you will have your muscle strength tested using special equipment, complete balance tests that measure how you distribute your weight, and take a six-minute walk to see how well you can move and how much endurance you have. The study is not yet recruiting participants, and if at any point you experience pain or discomfort, or decide to stop, you can withdraw without any problem. This research aims to better understand mobility after amputation to help create better treatments and support for amputees.

Eligibility criteria

• Inclusion Criteria:
• Individuals will be included in the study if they:
• • Are between 18 and 50 years of age
• • Are literate
• • Have unilateral transfemoral amputation
• • Have no cardiovascular, orthopedic, cognitive, or neurological conditions that could negatively affect balance, gait, or muscle strength
• • Are able to ambulate independently with a prosthesis
• • Have been walking for at least 6 months
• • Voluntarily agree to participate in the study
• Exclusion Criteria:
• Participants will be excluded from the study if:
• • They develop complications such as pain (rated 3 or higher on the Visual Analog Scale) or stump irritation during the course of the study
• • Their residual limb length is less than 25 cm from the greater trochanter, which exceeds the limitations of the isokinetic dynamometer attachments used in the study
• • They voluntarily withdraw from the study - in such cases, their data will be removed from the records
