| Abstract: | Objective To analyze characteristic changes of shoulder muscles by investigating surface electromyographic regularity changes before and after the treatment of Frozen shoulders. Methods 7 cases of frozen shoulders were selected, surface electromyography (sEMG) before and after treatment were recorded by AMT-8 EMG recorder. The collected data was processed using MATLAB software integrated EMG (IEMG) value were obtained. Then the IEMG data were statistically analyzed using Stata11.0 software and compared. Results ①The differences of abduction deltoid and infraspinatus muscle IEMG values before and after treatment were statistically significant (P ＜0.05), while IEMG values changes of biceps, triceps, pectoralis major, latissimus dorsi and trapezius before and after treatment were not statistically significant (P＞0.05); changes of adduction IEMG values of all muscles were not statistically significant (P＞0.05). ②Changes of flexion IEMG values of biceps before and after treatment were statistically significant (P＜0.05), while IEMG values changes of pectoralis major, infraspinatus muscle, latissimus dorsi, trapezius, deltoid, triceps before and after treatment were not statistically significant (P＞0.05). Changes of extension IEMG values of triceps before and after treatment were statistically significant (P＜0.05), while those of pectoralis major, infraspinatus muscle, latissimus dorsi, trapezius, deltoid and biceps were not statistically significant (P＞0.05). ③IEMG values of all the muscles during external rotation, internal rotation before and after treatment IEMG were not significantly different. Conclusion ①After treatment, the outreach functions of infraspinatus and deltoid muscles were improved, while adduction functions of all muscles were not improved. ②Flexion function of biceps was improved significantly after treatment as well as extension function of triceps.③Extemal rotation, internal rotation functions of all muscles were not improved significantly. |
