Outline of Final Research Achievements |
This study compared the effect of the load of the upper limb on the stiffness of supraspinatus muscle regions during isometric shoulder abduction in the scapular plane in healthy individuals and patients with a rotator cuff tear. And this study aimed to investigate the time-course changes in the active stiffness of the supraspinatus muscle after arthroscopic rotator cuff repair. The anterior superficial region could be a focal point of quantitative dysfunction evaluation of the supraspinatus muscle in the case of a rotator cuff tear. Moreover, it is important to consider the rehabilitation of the anterior superficial region after arthroscopic rotator cuff repair. Moreover, supraspinatus muscle rehabilitation is required 3 months postoperatively.
