Effects of Low Level Laser Therapy on Knee Pain and Function in Patients With Knee Osteoarthritis
In Brief
A clinical study evaluating Low level laser therapy and Conventional Exercise Therapy for Knee Osteoarthritis. Completed, enrolled 44 participants across 1 site.
Detailed Summary
The study will be Randomized Controlled Trial. It will be conducted in Allied Hospital Faisalabad. The study will be completed in four months duration. Consecutive sampling technique will be used for data collection. A sample size of 40 patients will be taken in this study. Participants will be divided into two groups. Group A will be treated by LLLT and conventional exercises. Group B will perform conventional exercises only. Numeric Pain Rating Scale will be used to measure pain. Western Ontario McMaster Universities Osteoarthritis Index Score (WOMAC) and Sit to stand test will be used to measure knee function. Goniometry will be used to measure ROM of knee. The participants will fill numeric pain rating scale and WOMAC as subjective measurements. Knee flexion ROM will be measured with universal Goniometer. Total 12 sessions will be given with three sessions per week. Post treatment readings will be taken at the end of 4th week. Data will be analyzed on SPSS 25.

Timeline
Interventions
* Gallium aluminium arsenide laser device will be used with wavelength of 850nm, power 100 mW, spot size of 1.0 mm and energy of 6J/point for 60seconds. Total 8 points will be irradiated. It will take 20 minutes. * Patient will receive treatment in supine position with the affected knee(s) slightly flexed supported by the pillow or rolled towel. * On the affected knee the laser probe will placed with full contact with skin at 8 points. Three points at medial side of the knee, three points at lateral side and two points at the medial edge of the bicep femoris muscle tendon and semitendinosus muscle tendon in the popliteal fossa
1. Quadriceps isometric strengthening exercises. 2. Range of motion and active stretching exercises applied to hamstring and quadriceps muscle. 3. Hamstring muscle isometric exercises 4. Active ankle pump. 5. Short arc terminal extension exercises for the knee joint. 6. Static and dynamic strengthening exercises for the hip abductors, adductors and extensor group of muscles. 7. Non-weight bearing progressive resistance exercises with weighted cuffs, with progression to closed chain exercises as patient's pain allows. 8. Isometric exercises were applied with 6 second contractions and rest period of 2 seconds. Isotonic exercises were started as 10 repetitions with half of weight of 10 RM, 10 repetitions with three fourth of this weight and 10 repetitions with whole 10 RM
