Study Overview
Brief Summary
This study aims to compare the effects of different ultrasound treatment durations on pain and physical function in patients with knee osteoarthritis. Sixty sedentary volunteers aged 18-85 with diagnosed knee osteoarthritis will be randomly assigned to three groups receiving ultrasound therapy for 5, 10, or 15 minutes, respectively, alongside conventional treatment. Pain and physical function will be assessed using the Visual Analog Scale (VAS), WOMAC Osteoarthritis Index, and 2-minute walk test at baseline and after 4 weeks of treatment. The results will help determine the optimal ultrasound treatment duration for improving symptoms in knee osteoarthritis patients.
Detailed Description
This clinical trial investigates the effects of different ultrasound therapy durations on pain relief and physical function improvement in patients with knee osteoarthritis. Sixty sedentary individuals aged 18 to 85 years diagnosed with knee osteoarthritis will be enrolled and randomly assigned to three groups receiving ultrasound treatment for 5, 10, or 15 minutes, respectively, alongside conventional therapy (such as hot packs, TENS, etc.).
Ultrasound therapy will be applied by a qualified physiotherapist at 1 W/cm² intensity and 1 MHz frequency in pulsed mode, for four weeks. Evaluations will be conducted at baseline and after treatment completion, using the Visual Analog Scale (VAS) for pain assessment, WOMAC Osteoarthritis Index for physical function, and a 2-minute walk test to measure walking performance.
This study aims to provide scientific evidence on the optimal ultrasound treatment duration for knee osteoarthritis, contributing to improved rehabilitation protocols. The findings will be prepared for publication in an international peer-reviewed journal.

Masking Description
This study is an open-label trial where both patients and treating physiotherapists are aware of the ultrasound treatment duration. Outcome assessors are blinded to group assignments to reduce assessment bias.
