| Outline of Final Research Achievements |
Understanding muscle mechanics, which reflects the mechanical properties of human skeletal muscle, is essential for elucidating the pathophysiology of movement dysfunction and advanced physiotherapy programs. The purpose of this study was to visualize and quantify the mechanical properties of muscle using the innovative ultrasound imaging, and to examine the validity and functional significance of viscoelasticity assessment. The results revealed that muscle elasticity is strongly related to joint passive torque and mechanical stress in human muscle. In addition, by investigating the effects of stretching on viscoelasticity of muscle tissue, findings were presented that could lead to the clinical usefulness of muscle mechanics assessment and form the basis of exercise therapy.
