The Effects of High Intensity Laser Therapy on Pain and Function of Patients with Frozen Shoulder

Abstract

Purpose: This study was to identify the effectiveness of high-intensity laser therapy on pain and function of a frozen shoulder.Methods: Thirty patients were assigned to two groups: the experimental group (n=15) and the control group (n=15). Both groups received traditional therapy for 4 weeks, 3 days a week. The experimental group, however, received an additional high intensity laser therapy.Pain was measured using the visual analogue scale (VAS). The functional ability was measured using the patient specific functional scale (PSFS). A paired t-test was used to determine any differences before and after the treatment, and an independent t-test was used to determine any differences between treatment groups.Results: Both groups showed a statistically significant difference for VAS and PSFS score (p<0.05). In comparison between two groups, more experimental group than control group statistically significant difference (p<0.05).Conclusion: There seems to be a positive effect on pain and function of frozen shoulder from using high intensity laser therapy.
