Quantification of plasticity of human intramuscular elasticity with noninvasive imaging and development of therapeutic exercise

本研究的目的是考察拉伸运动对肌腹僵硬的影响。结果表明，静息肌肉的僵硬出现一过性下降，提示静息僵硬程度较低的个体关节柔韧性较大。肌肉之间僵硬指数的可变性可能与伸展过程中肌肉之间被动张力的可变性有关。用超声弹性图量化肌肉僵硬将为开发有效的治疗运动提供有用的信息。

The purpose of the study was to examine the effect of stretching exercise on the stiffness of muscle belly. The results demonstrate the transient decreases in the stiffness of the resting muscle and indicate that joint flexibility is greater in individuals with lower resting stiffness. Variability in the index of stiffness between muscles may be related to variability in passive tension between muscles during stretching. Quantification of muscle stiffness with ultrasound elastography would provide useful information to develop effective therapeutic exercise.
