Reaction Time After Mobilization

Study Overview
=================
Brief Summary
-----------------
This clinical trial aims to look at the influence of wrist Mulligan mobilizations on hand reaction time in healthy people. The main question it aims to answer is: 1-Do hand mobilizations reduce reaction time?

Detailed Description
-----------------
In the treatment of musculoskeletal problems, manual therapy techniques are often used to restore movement and alleviate pain. The period between the initial muscular response or movement in response to a stimulus is referred to as reaction time. There is growing evidence for the benefit of manual mobilization for limb dysfunction, including shoulder and elbow pain, but there is little literature on hand mobilization and little research on its influence on hand reaction time in healthy individuals. The study comprised 60 healthy participants who completed a voluntary consent form. They were divided into two groups: research and sham mobilization. Participants in the study group had mediolateral wrist glide, anteroposterior 1st MCP glide, and anteroposterior and mediolateral glide. Applications were performed to the wrist, first metacarpal, and CMC joints in three sets of six repetitions. The patient in the sham mobilization group remained in the same posture for the same amount of time without gliding. The Nelson Hand Reaction Test was used to assess hand reaction before and after application. A 50 cm ruler was used, and the average of five measurements in cm was recorded and interpreted to sec.

| Experimental: İntervention<br>In the study group, wrist mediolateral glide, 1st MCP joint anteroposterior glide, CMC joint mediolateral, and anteroposterior glide were applied to the individuals by an experienced physiotherapist. Applications were made 6 times with 3 repetitions | Other: Passive Joint Mobilization<br>* Wrist mediolateral glide, 1st MCP joint anteroposterior glide, CMC joint mediolateral, and anteroposterior glide were applied to the individuals.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Hand Reaction Time | The time lapse between the application of stimulus and the generation of appropriate voluntary responses in an individual is known as reaction time (RT). It has been used widely in the assessment of executive functions, neuropsychological functions, and motor cognitive processing speed (MCPS). | Immediate after mobilization |
