Abstract
Purpose: This study was conducted to investigate the effect of polarized light therapy on incisional pain after cesarean section. Methods: Forty patients complaining from incisional pain post cesarean section participated in this study. They were selected randomly from Elmenia University Hospital for Gynecology and Obstetrics in Elmenia. Their ages were ranged from 25-35 years old. Design: Design of study was pre and post experimental design. They were divided into two groups equal in number, group A (Control Group) consists of 20 patients in 1st 24 hours after cesarean section. They were treated by traditional medical treatment immediately after recovery from anesthesia. group B (Study Group) consists of 20 patients in 1st 24 hours after cesarean section. They were treated by traditional medical treatment immediately after recovery from anesthesia and polarized light therapy with energy density of an average of 2.4 J/cm2 15 minutes/session, one session /day for 5 consecutive days. Measurements: Visual analogue scale (VAS) and electronic algometer were used to measure intensity of incisional pain post cesarean section in both groups (A&B) before and after treatment. Results: Results of this study found that there was significant decrease of VAS and significant increase of pressure algometer after treatment in both groups A and B when compared with corresponding pre-treatment value. Between groups, before treatment there was no significant difference in mean values of VAS and pressure algometer while after treatment, there was significant difference between both groups (A and B) (with favor of group B, more decrease VAS and more increase in pressure algometer)
