Summary

this study will be conducted to compare between high power laser and low-intensity laser on ultrasonographic and functional outcomes in patients with knee osteoarthritis

Conditions

Interventions

OTHER

high power laser

Sessions will performed with scanning in longitudinal and perpendicular direction on the medial and lateral sides of the knee with Laser scanner machine. handpiece was positioned in contact and perpendicularly while the patient in a supine lying position with the knee flexed at 30° to open the joint surfaces to the laser beam (optical windows). The scanning was performed transversely and longitudinally in the anterior, medial, and lateral aspects of the knee joint with emphasis on the application on the joint line between the tibial and femoral epicondyles. The total energy delivered to the patient during one session was 1,250 J through three phases of treatment. The initial phase is performed with fast manual scanning with a total of 500 J. In the initial phase, the laser fluency is set to two successive subphases of 710 and 810 mJ/cm2 for a total of 500 J.

OTHER

low level laser

patients will receive laser with 0.5 W to gain energy density of 6 J/cm2, and total energy of 240 J during one session. LASER apparatus that will be used is Chattanoga Intelect Laser with 850nm wavelength and 200mW power Lasers. Same three phases like HPL with different energy dose. First phase: Fast manual scan 100 J. Second 10 point joint line phase with evey point 14 seconds and 4J to deliver a total of 40 J in this phase. Third phase: Slow manual scan 100 J.

OTHER

conventional physical therapy

the patients will receive conventiobal physical therapy in the form of Exercise therapy program (1) Warm-up exercises: Walking at the usual speed on a flat surface for 10 min with hamstring and calf gentle stretches.(2) Major exercises for knee OA: Straight leg raise, quadriceps setting, heel raise, one leg balance, step ups, and quadriceps strengthening exercises. The US protocol consists of continuous ultrasonic waves of 1 MHz frequency and 1 W/cm2 intensity applied with a 5-cm diameter applicator. The patients will be placed in a supine position, and the US applied to the medial and lateral parts (5 min on each side) of the knee in circular movements with the probe at right angles to ensure maximum absorption of the energy.
