Influence of Scapula Training Exercises on Shoulder Joint Function After Surgery for Rotator Cuff Injury

BACKGROUND: The aim of this study was to assess the clinical effectiveness of scapula training exercises on shoulder function after surgery for rotator cuff injury. MATERIAL/METHODS: Forty-six patients with rotator cuff injury after surgery were randomized into the experiment group or control group. Both groups were treated with conventional therapeutic exercise and physical therapy, and scapular training exercise was added to the experiment group. Patient status was evaluated by Constant-Murley scale (CMS), visual analogue scale (VAS), and the active range of motion (ROM) of the shoulder before and after 6 weeks and 12 weeks of treatment. RESULTS: After 6 weeks and 12 weeks of treatment, all evaluations of the 2 groups were significantly improved as compared with those before treatment (P<0.05). Moreover after 6 weeks of treatment, the CMS (pain, daily life, range of activity, total scores), VAS and ROM (anteflexion) in the experimental group were significantly better than those in the control group (P<0.05). However, there was no significant difference in CMS (strength test) and ROM (abduction, rear extension) (P>0.05). After 12 weeks of treatment, all items in the experimental group were significantly improved compared to the control group (P<0.05). CONCLUSIONS: The combination of conventional rehabilitation interventions and scapular training exercise were an effective treatment of the shoulder dysfunction. Moreover, increased Scapula training exercise had better effect on the improvement of shoulder function.
