Background: Recently Low-level laser therapy (LLLT) is commonly used modality and thought it have analgesic and bio-modulatory effects. Our objective was to Know the effects of LLLT and possible changes in joint Stiffness, Pain and Disability of patients with knee osteoarthritis (KOA) and comparing it to the More commonly Used Modality Therapeutic ultrasound(US).
Methods: 40 subjects with a mean age of 52 years having clinical diagnosis of knee osteoarthritis and full filled the inclusive criteria are taken. After the initial measurements, the subjects are randomly assigned into 2 groups. Group-A performed the Low-level laser therapy,Group-B performed a ultrasound (US). Both Groups Received the Treatment in Duration of 4weeks– once daily for 5 days a week. Along with this technique A standard exercise protocol was performed. After the treatment, subjects were evaluated for their pain profile using visual analogue scale, and WOMAC scale was used to know the status of pain, stiffness, and physical function.
Results: For within group comparison we used Paired t-test analysis, For Between group comparison we used Independent t-test for statistical analysis. At the end of 4 weeks It was found that subjects treated with Low level Laser therapy showed significant improvement in terms of VAS scores and WOMAC (P=0.000) and patients treated with US showed significant improvement in terms of VAS scores and WOMAC (P=0.000).When compared between Groups the VAS and WOMAC showed a significant improvement in Low Level Lasertherapy than the Ultrasound Group (P=0.000).
Conclusion: Our Results shows that the LLLT and Ultrasound Reduces pain, joint stiffness and Disability in Knee Osteoarthritis and LLLT is more effective than the Ultrasound.
