Assessment of Strength, Balance, and Function in Above-Knee Amputees in Relation to Residual Limb Length

The goal of this observational study is to learn how muscle strength, balance, and functional ability are affected in people with above-knee (transfemoral) amputations. The main questions it aims to answer are:

How does the length of the lost part of the leg, compared to the intact leg, affect muscle strength, balance, and functional capacity?

Is muscle strength at specific lower limb joints related to balance and performance ?

Participants will:

Have muscle strength measured at all intact lower limb joints using an isokinetic dynamometer

Complete balance assessments using force platform technology that measures weight distribution and evaluates both static and dynamic balance

Perform a six-minute walk test to evaluate endurance and functional capacity

The study will help improve understanding of how limb length and joint-specific muscle strength impact mobility, supporting the development of better rehabilitation programs for amputees.
