Brief summary
Background: Osteoarthritis (OA) is a joint disease commonly found in the knee. Therapeutic exercise has been known as the most common therapy to treat OA, however, therapy only focuses on reducing symptoms, not on treatment of the disease which help reduce cost and improve long term quality of life. Objective: This randomized controlled trial aim was to compare the effectiveness of Stochastic Resonance Therapy-Whole Body Vibration (SRT-WBV) vs. Balance Board (BB) training on knee pain, knee function and quality of life in obese patients with osteoarthritis. Design: Randomized controlled trial. Methods: Forty-four subjects diagnosed with Grade I-II Osteoarthritis Kellgren Lawrence and Grade I obesity were included, randomized to two treatment groups, the SRT-WBV (n=22) or BB (n=22) to complete a series of exercises over eight weeks. Evaluation using the following clinical outcomes: Visual Analog Scale (VAS), Timed Up and Go test (TUG), Single leg stance (SLS) test, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Short Form 12 Health Survey Questions (SF-12).
Interventions
DEVICEStochastic Resonance Therapy-Whole Body Vibration
A total of 16 therapeutic exercise sessions were conducted during the intervention where 2 sessions were conducted every week, separated by at least one day. Specifically, subjects assigned to either group, with each session began with standardized warm-up exercises lasting approximately 5-10 minutes, followed by specific therapeutic exercises such as SRT-WBV and Balance Board.
DEVICEBalance Board
The balance board intervention used different durations as its intensity, such as 7.5 minutes, 10 minutes, 12.5 minutes, and 15 minutes continuously without resting period. The intensity of exercise was progressively increased every 2 weeks until completion of the program.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Knee function (WOMAC Total Score) | 8 weeks | 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. |
| Timed Up and Go Test (Balance) | 8 weeks | 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. |
| Straight Leg Raise Test | 8 weeks | Balance/flexibility will be assessed using the Straight Leg Raise test. The maximum angle (in degrees) achieved during leg elevation will be recorded. |
| Knee Pain (VAS Score) | 8 weeks | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Quality of Life (SF-12 Score) | 8 weeks | Quality of life will be assessed using the SF-12. Scores will be calculated according to standard scoring procedures. |
