Effectiveness of Low-Level Laser Therapy and Pulsed Ultrasound Combined with Exercise for Osteoarthritis of Knee

Abstract

Background: A slow loss of cartilage, pain, functional impairment, and a decreased quality of life are allcharacteristics 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 thatare fibrous, and raise pain thresholds. Laser beams having a wavelength of between 600 and 800 nanometers areproduced by limited laser treatment. It stimulates regeneration and the release of beta-endorphins by increasingprotein synthesis in synovial fluid.Purpose: To find the effectiveness of Low Level Laser Therapy and Pulsed Ultrasound combined with exercise forosteoarthritis of knee.Materials and Methods: Total of 60 participants were selected from ACIAN Ortho clinic. According to inclusionand exclusion criteria, the participants were explained about the treatment safety and written consent wasobtained. The participating subjects were divided into two groups, Low Level Laser Therapy with exercise groupand Pulsed Ultrasound with exercise group. All the subjects underwent pretest measurement with ROM andWOMAC 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 LowLevel Laser Therapy. The Low Level Laser Therapy Group were significantly higher than the Pulsed Ultrasoundgroup, with a p value of <0.0001Conclusion: Low Level Laser Therapy is more effective than Pulsed Ultrasound for osteoarthritis of knee.
