| Outline of Final Research Achievements |
The purpose was to assess quantified muscle activities during elevation in shoulders with reverse shoulder arthroplasty or superior capsular reconstruction using the positron emission tomography (PET). Subjects underwent scaption exercises at the timing of pre- and post-injection of fluorine-18-labelled FDG. This study analyzed for 15 muscular regions including rotator cuff muscles (supraspinatus, upper and lower infraspinatus, upper, middle and lower subscapularis, teres minor), periscapular muscles (anterior, middle and posterior deltoid, upper and lower trapezius, serratus anterior, levator scapulae, rhomboid), and the standard uptake value for each muscular region was calculated as a quantified value for muscle activities during the exercises. For each muscular region, the values among the groups were compared to identify the patterns of muscle activities. This study revealed characteristic patterns of shoulder muscle activities after reconstruction surgeries for rotator cuff tear.
