简要总结
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).

研究组 & 干预措施
Stochastic Resonance Therapy-Whole Body Vibration
Subjects assigned to the SRT-WBV group were required to stand on the footboard of the SRT-WBV (SR Therapiesysteme GmbH & Co. Lifescience KG, Berlin) device with shoulder width stance, and knees bent at 30 degrees, facing forward. The trim settings progressed from weak (45 seconds with 8 repetitions), to mild (55 seconds with 8 repetitions), average (60 seconds with 6 repetitions), and strong (60 seconds with 6 repetitions), with intensity increased at two-week intervals. Each repetition was separated by a resting period that had the same duration as the trim settings (weak: 45 seconds, mild: 55 seconds, average and strong: 60 seconds).
干预措施: Stochastic Resonance Therapy-Whole Body Vibration (Device)
Balance Board
Subjects were required to stand on the balance board with knees bent at 30 degrees and both hands placed on the chest with eyes opened. 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.

结局指标
主要结局
Knee function (WOMAC Total Score)
时间窗: 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)
时间窗: 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
时间窗: 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)
时间窗: 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.
次要结局
- Quality of Life (SF-12 Score)(8 weeks)
