Outline of Final Research Achievements

We investigated the relationship between atrophy, assessed using the muscle belly ratio, and function, measured using ultrasound elastography, in 20 cases of rotator cuff tear underwent arthroscopic rotator cuff repair and exercise. Our results showed that in both 10 cases with and 10 cases without atrophy, the muscle belly ratio values before and after surgery showed little change, without significant differences. Additionally, although there was a tendency for functional changes to increase, no significant differences were found. Despite the small number of cases and the need for careful interpretation, it was suggested that there might be functional changes, while the degree of atrophy showed little change. Future studies should have long-term follow-up.

Academic Significance and Societal Importance of the Research Achievements

骨格筋の病態は，高齢者が寝たきりや要介護状態につながる原因の一つとして注目を集めている．なかでも骨格筋の萎縮はリハビリテーションで改善可能な因子であり，その機序の解明は骨格筋の病態の早期発見と予防または治療において重要である．本研究は，腱板断裂例を対象にした1年の追跡調査により骨格筋の萎縮自体の改善に先んじて機能の改善が生じる可能性を示した．この成果は，今後骨格筋の病態に対する介入結果とその効果を解釈する上で有用である．
