Acute Effect of Whole Body Vibration on Reaction Speed and Proprioception

Study Overview
=================
Brief Summary
-----------------
It will be determined whether the application of whole body vibration has an immediate effect on upper extremity reaction speed and proprioception.

Detailed Description
-----------------
Muscles and tendons are among the mechanisms affected by whole body vibration. In this way, it is thought that TVV indirectly affects the reaction speed of individuals. In the light of this information, this study was planned to investigate how whole body vibration application affects proprioception and reaction speed. The reaction rate and instantaneous effect of the virion given at 30 Hz and 2 mm amplitude in the push-up position on proprioception will be investigated. The aim of this study is to investigate the instantaneous effect of whole body vibration on reaction speed and proprioception in the upper extremity in healthy individuals.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Nelson Hand Reaction Test | 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. | All measurements take 30 minutes for each individual, before and immediately after the application on the same day. | 
| Reaction Rate Evaluation with Sway Medical Smartphone Application | 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. | All measurements take 30 minutes for each individual, before and immediately after the application on the same day. | 
| Upper extremity proprioception measurement | 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. | All measurements take 30 minutes for each individual, before and immediately after the application on the same day. |
