简要总结
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.
详细描述
Bilateral rectus femoris muscle thickness was measured by two independent examiners using an ultrasound. Bilateral knee extension strength was measured via handheld dynamometer (Jamar, Bolingbrook, IL, USA). Functional strength and walking were assessed by Step-up-over (SUO) and Walk-across (WA) tests of NeuroCom Balance Master® device (NeuroCom International, Clackamas, OR, USA).

结局指标
主要结局
Ultrasonographic cross-sectional area of rectus femoris measurement
时间窗: through study completion, an average of 6 months
Images were obtained at the bulkiest area of muscle at mid-thigh (midway between the anterior superior iliac spine and the upper pole of the patella) while the participant lay in the supine position with lower limbs are extended and relaxed. The probe was held axially with a light touch in order not to cause any difference in the muscle volume. The rectus femoris cross-sectional area of both limbs (CSA-RF) (mm2) was calculated.
