Comparing Whole-Body Vibration vs. Balance Board Exercise for Pain, Function, and Quality of Life in Obese Adults With Knee Osteoarthritis

Knee function (WOMAC Total Score)

Knee function was assessed using the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) questionnaire where pain score, stiffness, and physical function were evaluated on a scale of 0-4, with higher scores indicating worse pain, stiffness, and functional limitations. The questionnaire contains 24 items and the WOMAC Osteoarthritis Index scores were then derived from the sum of the scores for the three subscales It was administered at the beginning and completion of the intervention, as well as every 4 weeks during the intervention.

Time frame: 8 weeks

Timed Up and Go Test (Balance)

Balance and mobility will be assessed using the Timed Up and Go Test. The time (in seconds) taken to stand up from a chair, walk 3 meters, turn, return, and sit down will be recorded.

Time frame: 8 weeks

Straight Leg Raise Test

Balance/flexibility will be assessed using the Straight Leg Raise test. The maximum angle (in degrees) achieved during leg elevation will be recorded.

Time frame: 8 weeks

Knee Pain (VAS Score)

Knee pain will be measured using the Visual Analog Scale ranging from 0 to 10, with higher scores indicating greater pain. Participants will rate their pain at rest while seated.

Time frame: 8 weeks
