Acute Effect of Whole Body Vibration on Reaction Speed and Proprioception

Primary outcomes

1. Nelson Hand Reaction Test

   Time frame: All measurements take 30 minutes for each individual, before and immediately after the application on the same day.

   The participant is asked to sit in the chair with the forearm and hand comfortably resting on the table. The tips of the thumb and index finger are positioned 8-10 cm away from the table, with the tops of the thumb and index finger parallel to each other. The tester asks the individual to hold the ruler between his thumb and index finger. At the same time, the patient is asked to look directly at the middle point of the ruler while holding it between his fingers. As soon as the ruler is released, the person is told to catch the ruler with his thumb and forefinger. The ruler is left and the numerical value on the upper edge of the subject's thumb, where the subject grasps the ruler, is read and recorded.

2. Reaction Rate Evaluation with Sway Medical Smartphone Application

   Time frame: All measurements take 30 minutes for each individual, before and immediately after the application on the same day.

   The person will sit comfortably on a chair and hold the smartphone with the thumbs on both sides. When the orange screen appears, the phone should quickly rotate the screen in the desired direction. Once you will do the test to learn the application. Then, the application is made three times and the reaction rate is calculated by taking the average time of these three applications.

3. Upper extremity proprioception measurement

   Time frame: All measurements take 30 minutes for each individual, before and immediately after the application on the same day.

   Elbow flexion, shoulder flexion and abduction 30 and 60 degree angles were measured with a digital goniometer. The elbow and shoulder positions were brought to the desired angle and they were asked to return to the same angle. The angle of deviation was recorded.
