Effectiveness of Low-Level Laser Therapy and Pulsed Ultrasound Combined with Exercise for Osteoarthritis of Knee
Keywords:Osteoarthritis of knee, Pulsed Ultrasound, Low Level Laser Therapy, Western Ontario and McMaster Universities Osteoarthritis Index, Range of motion, Isometric exercise.
Background: A slow loss of cartilage, pain, functional impairment, and a decreased quality of life are all
characteristics of the degenerative inflammatory sickness- osteoarthritis of the knee, which affects the whole joint.
Pulsed ultrasound primarily has properties to boost tissue metabolism, improve the extensibility of tissues that
are fibrous, and raise pain thresholds. Laser beams having a wavelength of between 600 and 800 nanometers are
produced by limited laser treatment. It stimulates regeneration and the release of beta-endorphins by increasing
protein synthesis in synovial fluid.
Purpose: To find the effectiveness of Low Level Laser Therapy and Pulsed Ultrasound combined with exercise for
osteoarthritis of knee.
Materials and Methods: Total of 60 participants were selected from ACIAN Ortho clinic. According to inclusion
and exclusion criteria, the participants were explained about the treatment safety and written consent was
obtained. The participating subjects were divided into two groups, Low Level Laser Therapy with exercise group
and Pulsed Ultrasound with exercise group. All the subjects underwent pretest measurement with ROM and
WOMAC at the beginning of the treatment. Study period : November 2022 to April 2023.
Results: Statistical analysis of data showed significant differences not only in the Ultrasound group but also in Low
Level Laser Therapy. The Low Level Laser Therapy Group were significantly higher than the Pulsed Ultrasound
group, with a p value of <0.0001
Conclusion: Low Level Laser Therapy is more effective than Pulsed Ultrasound for osteoarthritis of knee.
