Summary

This study looks at whether using a blood pressure cuff on the thigh can make leg muscles stronger and improve walking in people who have lost a leg above the knee. Researchers will measure strength, walking ability, and daily activity before and after the intervention. The goal is to find a simple, non-drug way to help people move better after a traumatic amputation.
