Abstract
Purpose: The current study was conducted to examine the effect of low level laser therapy (LLLT) on quadriceps muscle strength in lower limb burn. Subjects and Methods: Sixty patients (37 males and 23 females) who suffered from second degree lower limb burn of thermal injury were participated in this study. Total body surface area (TBSA) for burns ranged from 20% to 35% and their ages ranged from 25-40 years. They were selected randomly from physical therapy department for Burns, Orabi Hospital for Burns, Alobour City. Procedures: group (A) (study group) composed of 30 patients who received LLLT before strengthening exercises for quadriceps muscle, 3 sessions /week for 8 weeks. group (B) (control group) composed of 30 patients who received strengthening exercises for quadriceps muscle, 3 sessions /week for 8 weeks. Patients in both groups were received traditional physical therapy program in the form of (range of motion exercise, stretching, splinting, massage, functional training for ambulation and activities of daily living). Method of evaluation was measurement of quadriceps muscle peak torque before and after 8 weeks of treatment for both groups by using isokinetic dynamometer
