Knee extension strengthening is one of the cornerstones of rehabilitation in prosthesis users with transtibial amputation. It is recommended in terms of increasing functional mobility, preventing the risk of fall and knee osteoarthritis. Therefore, there is a need for objective measurements to evaluate changes in functional strength and walking through the rehabilitation process. Muscle thickness measured by ultrasound was found to be valid and highly correlated with magnetic resonance imaging and dual-energy X-ray absorptiometry measurements and shown to reflect the strength and functional outcomes in various diseases. The first aim of this study is to reveal the rectus femoris muscle thickness alteration in prosthesis users with transtibial amputation compared to able-bodied controls and establish its correlation with functional strength and walking tests. The second aim is to determine intra- and inter-rater reliability and construct validity of the rectus femoris muscle thickness measured by ultrasound in prosthesis users with transtibial amputation.
