Effects of static stretching and hold-relax on recovering range of motion and reducing pain of patients with frozen shoulder

오십견 환자의 관절 가동 범위 회복과 통증 완화에 미치는 정적 신장 기법과 유지-이완 기법의 효과

Background : Patients with frozen shoulder have pain and limited range of motion (ROM) at the affected shoulder. Shoulder pain of these patients usually decreases with recovery of range of motion. The aim of this study is to identify effects of static stretching and hold-relax on recovering ROM and reducing pain of patients with frozen shoulder. Methods : In this study, 15 patients with frozen shoulder who were only treated with physical therapy were recruited. Patients who received any surgical procedure or hydrotherapy were excluded. The subjects were divided randomly into 3 groups; control(n=5), static stretching(n=5) and hold-relax(n=5) groups. Patients were treated with stretching and the total number of treatments was 12 times. The ROM was measured at baseline, after fourth, eighth and final treatments. Shoulder pain and disability index(SPADI) scores were assessed before and after doing all treatments. Repeated measures ANOVA was used to analyze ROM change within each group. Changes of ROM between groups was analyzed by one way ANOVA followed by post hot analysis(Tukey's HSD). SPADI score within each group analyzed using Wilcoxon signed ranks test. A p-value<0.05 was considered statistically significant. Study Design : Repeated measures design. Result : There were significant differences of ROM in both treatment groups except internal rotation of static stretching group. ROM was significantly increased in treatment groups compared with control group, but the difference of ROM change between two treatment groups did not differ significantly. SPADI scores for treatment groups significantly decreased compared with pre-SPADI score. Conclusion : The result suggests that hold-relax can be more effective than static stretching to recover range of motion and alleviate shoulder pain on patients with frozen shoulder.
