Abstract
Purpose: The current study was conducted to investigate the efficacy of low level laser therapy (LLLT) on shoulder pain and disability after neck dissection surgeries. Subjects and methods:Thirty male and female patients had selective neck dissection surgery. Their ages ranged from 20 to 55 years. They were selected from Tanta Cancer Center and divided randomly into two groups: group (A) composed of 15 patients (14 patients with unilateral neck dissection and 1 patient with bilateral neck dissection) who received LLLT in addition to traditional physical therapy exercise program and group (B) composed of 15 patients (13patients with unilateral neck dissection and 2 patients with bilateral neck dissection) who received traditional physical therapy exercise program only. Patients in each group received the treatment (3sessions/week) from the end of1st month postoperative till the end of 2nd month postoperative. Postsurgical medications and wound dressing were provided for all patients in each group. Shoulder pain and disability index (SPADI) and visual analogue scale (VAS)were used to measure the shoulder pain and disability pre treatment (at the end of 1stpostoperative month) and post treatment (at the end of 2nd postoperative month). Results: group A and B showed significant improvement in SPADI and VAS at the end of 2nd month postoperative compared with them at the end of 1st month postoperative. There was significant improvement in SPADI and VAS at the end of 2nd month postoperative of group A compared with group B
