IRCT20101017004952N11 IRCT 2022-03-05 Tarbiat Modares University Effect of two frequencies of whole body vibration and transmissibility to the lower limb's joints in the postmenopausal women The comparison of whole body vibration with frequency of 20 and 40 Hz on the transmissibility to the lower limb's joints and center of pressure sway in the postmenopausal women 2022-03-06 anticipated 20 Complete https://irct.ir/trial/61324 interventional Randomization: N/A, Blinding: Single blinded, Placebo: Not used, Assignment: Single, Purpose: Health service research, Blinding description: The outcome measures will record and evaluate by a motion analysis system expert who does not know the steps and specifications of the frequency and amplitude of the whole body vibration device. N/A Balance in postmenopausal women. Intervention group: postmenopausal women. A group of postmenopausal women who receive whole body vibration with frequency of 20 and 40 HZ. The participant will be placed on the WBV plate barefoot with semi-squat and will have one of the following modes: Off vibration (control), 20 Hz and 2 mm, 20 Hz and 4 mm, 40 Hz and 2 mm, 40 Hz and 4 mm. Before and immediately after each of the above modes, the center of pressure sway will be recorded. Each mode is composed of two 30-second intervals with a 10-second break between them. During vibration, the transmission of the acceleration (transmissibility) is measured at the level of the lower limb joints (Hip, Knee, and Ankle joints).. Yes - There is a plan to make this available What will be shared: The data will be presented in the prepared article after coding the participants. At the request of the reviewers, details of data and statistical methods will be provided. When: Access since May 2022 To whom: Researchers in the field of physiotherapy and other health groups Conditions: Researchers in the field of physiotherapy and other health groups can receive it upon formal request Where to obtain: Giti Torkaman, Physical Therapy Department, Tarbiat Modares University How to obtain: Upon receipt of the request, the data will be shared for up to one month Comments:
