The Effect of Whole-Body Vibration Treatment Before Total Knee Arthroplasty

The study's objective is to investigate the effects of whole-body vibration therapy administered before surgery on various factors related to patients who undergo total knee arthroplasty. These factors include pain, swelling, skin temperature, normal joint movement, knee joint position sense, knee extensor muscle strength, functional status, and patient satisfaction.

The study will include participants aged 50-80 who are planning to undergo total knee arthroplasty. According to the sample size analysis, a total of 40 people will be included in this study. The enrolled participants will be randomly assigned to one of two parallel groups: the whole-body vibration group or the sham whole-body vibration group. Both groups will receive standard patient education and exercise training.The experimental group will receive whole-body vibration along with exercise on the whole-body vibration device, while the control group (sham group) will receive sham vibration on the same device. All participants will receive treatment for a total of 5 days, one session per day.

The vibration will be applied for 10 minutes (30 seconds rest, 30 seconds training, 10 reps) in total with a low frequency (20 HZ) and low amplitude (2mm). Participants will be asked to stand in a squatting position by semi-flexing (30°) their knees during the 30-second vibration period.

The sham-whole body vibration treatment will follow the same procedures with the vibration machine off.

The pain severity will be evaluated using an NRS rating from 0 to 10, with 0 representing no pain and 10 representing maximal pain.

The 36-Item Short-Form Health Survey (SF-36) is a general scoring instrument used to provide a health profile comprised of eight scaled scores. Each scale is instantly turned into a 0-100 scale, allowing identification of the patient's physical and mental status. A higher score means a better result.

The GROC score, which has seven response options ranging from 'much worse' (a score of 0) to 'much better' (a score of six), will be used to determine the subject's perception of overall improvement.

Inclusion Criteria: Patients with advanced idiopathic knee OA and scheduled for unilateral total knee arthroplasty will be considered candidates for the present study and will be asked to participate Exclusion Criteria: if they had undergone another hip or knee joint replacement in the previous year if they had any medical condition in which exercise was contraindicated if they had any disease that affected functional performance
