Whole-body Vibration Training on the Elderly With Combined Bilateral Knee Osteoarthritis

This study will aim to evaluate the effects of whole-body vibration training (WBVT) on body composition, muscle strength (hand grip strength), and physical performance [gait speed (GS), 5-time chair stand test (5CST), and short physical performance battery (SPPB), pain intensity, triglycerides in older people with knee OA and sarcopenic obesity in a group of Men compared to group of females.

About this study

Both groups received the intervention 3 times a week for 12 weeks. WBVT group. Each intervention lasted 30 min, which included 5 min of warm-up, 20 min of vibration training, and 5 min of relaxation.

Neurological or respiratory conditions or injuries (ie, dementia, Alzheimer's disease, multiple sclerosis, chronic obstructive pulmonary disease), rheumatoid arthritis and clinical depression.

Treatment and study plan

Whole-body vibration training

Other

Whole-body vibration therapy stimulates muscle contraction. It can increase muscle function to a level like that of classical resistance training, but with the advantage of being more convenient and safer

Primary outcomes

Physical performance

Time frame: 8 weeks

These are standardized tests used to assess lower limb strength, mobility, and overall functional ability in elderly patients it includes: 1. Gait speed (it is the rate a person can tolerate walking measured in meter per seconds (ask the person to walk at their usual comfortable pace for 10 meters; and record how many seconds it takes to complete this distance and evaluate the recorded time before and after the treatment); 2. 5-time chair stand test; t evaluates how quickly a participant can perform 5 successive sit-to-stand without using their arms (it evaluate the time taken to complete 5 repetitions, a. ≤ 12 seconds is considered normal physical performance, b. > 15 seconds may indicate lower extremity weakness, mobility limitations, or increased fall risk, c. Unable to complete indicates significant functional impairment). All measurements will be carried out before the treatment and after the end of the treatment.
