Abstract: Frozen shoulder was a common but poorly defined syndrome that leads to pain and stiffness of the shoulder. It is very often referred for physiotherapy management. Due to variation in treatment approaches and different outcome measures, no consensus can be made for the best management approach of frozen shoulder. Electroacupuncture (EA) had been considered as one of the best choice in managing frozen shoulder and was increasingly used in daily clinical practice. However, there was a lacking of research evidence in supporting its usage for frozen shoulder patients. Interferential Therapy (IFT), another commonly used modality for managing frozen shoulder, was also lacking of research support was examined in the present study. The objective of this study was to investigate the effectiveness of electroacupuncture (EA) and interferential therapy (IFT), combined with a specific set of shoulder exercises, in the management of frozen shoulder. A total of 70 patients were recruited into the study over a period of 12 months. They were randomly allocated to EA group, IFT group and control group and were treated accordingly for 4 weeks. The outcome measures were Constant Murley Assessment (CMA) score and Visual Analog Scale (VAS). A mixed model analysis was employed to compare the outcome measures between the three groups at baseline, post-treatment, one-month, three-month and six-month subsequent follow-up. The level of significance was set at 0.05. Results shown after 10 sessions of EA or IFT treatment, CMA increased significantly (p=0.00) and VAS decreased significantly (p=0.00) in both EA and IFT group and this improvement could well maintain at six-month follow-up. Therefore, it was concluded that both EA and IFT was effective in relieving pain and regaining shoulder function for frozen shoulder patients as compared to the control group. However, no significant difference in CMA or VAS was found between the EA and IFT group throughout the whole experimental period. This study provided evidence in supporting the usage of EA and IFT in the management of frozen shoulder.
