study effect of whole body vibration on arthrogenic muscle inhibition of quadriceps muscle in knee osteoarthritis patients

Determine the effectiveness of using whole-body vibration training in reducing arthrogenic inhibition, increasing quadriceps muscle strength, improving pain, improving function, improving balance and improving quality of life in patients with knee osteoarthritis

Clinical trials with intervention, placebo and control groups, double-blind, randomized tables were used for randomization.

Location: Faculty of Rehabilitation Sciences, Shahid Beheshti University Blinded: Participants, Analyzer, Variable Tester

Criteria for entering the study: • People with primary osteoarthritis of the knee with grades 2 and 3 based on Kellgren and Lawrence criteria • People with chronic knee pain (having pain in the knee or around the knee most of the time, having pain in the knee in the last year) • Age range 30 to 60 years • no participation in reinforcement sports programs for at least the last 6 months • BMI 22 to 30. • Have at least 10% arthrogenic inhibition in the quadriceps muscle in the affected knee. - Criteria for not entering the study: • Severe cardiovascular disease that prevents exercise. • Drug use. • Perform total knee arthroplasty or any other surgery on the lower limbs • Existence of pain with intensity above 5 based on a visual scale of pain during the study • History of knee surgery, rheumatic or infectious diseases of the knee and cancer • Secondary osteoarthritis

the intervention group receives 10 session vibration therapy with specific settings, the placebo group receives 10 session vibration therapy while the device is off and makes no vibration. at the beginning of each session, all three groups including intervention,placebo and control group recieves routine knee OA physiotherapy.

First, when the sampling is done in a simple and accessible way, each sample is given a specific code, then each code is written on a piece of paper and the papers are poured into a container, the number of samples of each group is drawn and The number of papers randomly leaves the container.

Keeping participants blind so that patients in the intervention group are visited on even days and the control group is visited on individual days, and each group is unaware of the existence of the other group. Keeping blind variables assessor in such a way that at the time of testing the variables, the assessor is unaware of the type of group therapy and only measured the variables in all participants. Keeping the data analyst blind so that he is unaware of each patient's treatment group at the time of reviewing and analyzing the data, and each patient is introduced to the analyzer with only one identifier code.
