简要总结
Tightness of hamstring muscle is known as a reduction in range of motion accompanied by a sensation of restriction in the posterior aspect of thigh. Numerous reasons can cause it, such as genetic susceptibility, compensatory tightness due to persistent abnormalities, and muscular strain. Tight hamstrings cause a small amount of knee flexion during exercise and require comparatively high quadriceps efforts to offset the hamstrings' passive resistance. This could result in knee joint pain that affects gait and raise the reaction forces at the patellofemoral joint.

结局指标
主要结局
Muscle strength
时间窗: 5 weeks
Microfit hand-held dynamometer (HHD) will be used for assessment of hamstring muscle strength. Each participant will lie prone on a standard treatment table. In this position, the participant will be instructed to bend their knee to 90° of knee flexion, where the Microfet 2 MMT-Wireless HHD will be placed on the lower leg, and a downward force toward the table will be held for 5s while the participant resists the downward force. The participant will be instructed to use their maximum effort. It will be performed three times, and an average will be recorded.
