ClinConnect Summary

This clinical trial aims to explore how using powered knee and ankle prostheses affects the walking ability of individuals who have had a leg amputated above the knee (known as transfemoral amputees). The researchers want to find out if providing extra power at the knee, the ankle, or both can help these individuals walk better. They will measure how well participants perform while using different types of prosthetic devices and after receiving special training to improve their walking skills.

To participate in this study, individuals need to be between 18 and 95 years old, have had a transfemoral amputation for at least six months, and be able to walk 50 meters with their prosthesis without help. Participants will be closely monitored and will have the chance to use advanced prosthetic devices that could potentially enhance their mobility. This study is currently recruiting, and anyone interested should check with their doctor to see if they meet the eligibility criteria.

Eligibility criteria

• Inclusion Criteria:
• • Ages 18-95
• • A unilateral transfemoral amputation
• • At least 6 months since definitive prosthesis fitting
• • Able to walk 50 meters (55 yards) with a prosthesis without the assistance of another person.
• • Medically cleared by physician to participate in study
• • English speaking
• Exclusion Criteria:
• • Weight greater than 250 pounds
• • Significant new injury that would prevent use of a prosthesis: The ability to consistently wear a prosthesis and perform activities of daily living and specific performance tasks is necessary to evaluate the relative benefits of the interventions.
• • Cognitive impairment sufficient to adversely affect understanding of or compliance with study requirements, ability to communicate experiences, or ability to give informed consent: The ability to understand and comply with requirements of the study is essential in order for the study to generate useable, reliable data. The ability to obtain relevant user feedback through questionnaires and informal discussion adds significant value to this study.
• • Significant other comorbidity: Any other medical issues or injuries that would preclude completion of the study, use of the prostheses, or that would otherwise prevent acquisition of useable data by researchers.
