High-Intensity Laser Therapy: Effectiveness on Knee Osteoarthritis Patients
- Conditions
- Osteoarthritis, Knee
- Registration Number
- NCT06549543
- Lead Sponsor
- Baskent University
- Brief Summary
The aim of this prospective, randomized, double-blinded study is to investigate the additional benefits of high-intensity laser therapy (HILT) over conventional physiotherapy, related to pain and function, in patients with knee osteoarthritis (KOA).
- Detailed Description
The study was performed in Baskent University Physical Therapy and Rehabilitation Unit. 43 patients of both sexes, who were diagnosed clinical and radiographic knee osteoarthritis, with Kellgren Lawrence Grade 2 and 3, were randomly assigned in two groups. Group 1 (n = 21) received TENS, HP, exercises (EX), and High-Intensity Laser Therapy (HILT; Nd:yag laser, 10W). Group 2 (n = 22) received the same interventions but placebo HILT. All interventions were applied for 10 sessions. The Visual Analog Scale (VAS), Western Ontario \& McMaster Universities Osteoarthritis Questionnaire (WOMAC), and Lequesne Algofunctional Index (LAI) were performed before, after, and at 12-week follow-up.

- Primary Outcome Measures
Name Time Method The Visual Analog Scale (VAS) 12 weeks The VAS was assessed before treatment, at the end of 10 sessions, and at the 12 week follow-up. Min score was 0 and max score was 100. Higher scores on the VAS indicate greater pain.
- Secondary Outcome Measures
Name Time Method Western Ontario & McMaster Universities Osteoarthritis Questionnaire (WOMAC) 12 weeks The WOMAC was assessed before treatment, at the end of 10 sessions, and at the 12 week follow-up. Higher scores on the WOMAC indicate poorer functional capacity and greater pain and stiffness.
Lequesne Algofunctional Index (LAI) 12 weeks The LAI was assessed before treatment, at the end of 10 sessions, and at the 12 week follow-up. Higher scores on the LAI indicate poorer functional capacity and greater pain and stiffness.
