Comparative Study between Low-Level Laser Therapy VS. Therapeutic Ultrasound along with Exercises in Patients with OA Knee

Study Design: Pre-post experimental study design. Background: Degenerative changes around knee joint involve ligaments and cartilages. It is heterogeneous group of conditions that leads to joint symptom and signs associated with integrity of articular cartilages. Objectives: Present study was undertaken to add on to available treatment methods for osteoarthritis knee and to find out the effectiveness of laser therapy and ultrasound therapy for treating osteoarthritis knee. Procedure: In this study, 30 participants were recruited based on inclusion and exclusion criteria. Laser therapy and ultrasound therapy was administered to them for a period of 2 weeks, 5 sessions per week. Pre and post assessment were taken using following outcome measures- Range of Motion (ROM), Numerical Pain Rating Scale (NPRS). Result: There was significant decrease in NPRS in patients which is suggestive of quality of life. Also, Knee ROM was found to be significantly increases amongst these participants. The outcome of NPRS and knee ROM was statistically analysed. It was found to be effective with significant P value<0.000. Conclusion: Ultrasound therapy is an effective treatment and can be used for treatment of patients with OA knee.
