The study of the Whole Body Vibration Therapy effects on Pain , Knee Range of Motion, Functional Activities, Electromyography Muscles Activity of the Lower Limbs and Postural Stability of Patients with Knee Osteoarthritis. 2016-02-20 anticipated 45 Complete https://irct.ir/trial/1099 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Other design features: The patients were randomly allocated to three groups: WBVT, placebo and control . It is worth noting that patients are not aware of the different treatment groups and were treated at different times. 2-3 Knee Osteoarthritis. Intervention 1: The whole body vibration training group will do their intervention on a vibration platform .The WBVT programme will be done on the Fitvibe vertical vibration platform with amplitude of 3 mm and frequency of 30 Hz. The patients will ask to stand barefoot on the platform with a 30 degree knee flexion during training. The vibration training will consist of two set with three repetitions of one-minute WBVT and one-minute rest between repetitions and five minute rest between the sets during the first week to avoid patients' muscles fatigue. Every week a set will be added to the WBVT program, so that the WBVT in the fourth week will be consisted of five sets. The patients will be allowed to sit down on a chair for the rest between the sets. Intervention 2: The patient in placebo group will do their intervention on a vibration platform as WBVT group while the vibration system is off and does not transmit any vibration to the patient's feet while standing in semi squat position. Their protocol will be similar to the WBVT group but without receiving vibration. The reason for designing a placebo group in this study is to evaluate the placebo and psychological effects of WBVT. Intervention 3: The practice at home group will be educated to do two exercises in three set with ten repetitions and a five-second hold for each exercise and a five-second pause. The exercise program of the group will consist of static contractions of quadriceps muscles and SLR which will be done twice a day at home. The exercise therapy course is also four weeks in this group.
