Changes on Pain and Range of Motion by the Use of Kinesio Taping in Subjects With Myofascial Trigger Point

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to demonstrate that the application of Kinesio Taping on a myofascial trigger point in the trapezius muscle able to cause a decrease of the trigger point pain and an increase of the cervical range of motion in asymptomatic subjects

Detailed Description
-----------------
The use of Kinesio Taping has become very popular for the treatment of many musculoskeletal disorders in recent decades. Of the six variants of application that has the Kinesio Taping, the space correction technique is suggested for pain management. The increased space achieved with this variant decreases the pressure Kinesio Taping by raising the skin directly over the treatment area, reducing chemical irritation receptors and therefore pain. The aim of this study is to demonstrate that the application of this variant of Kinesio Taping on a myofascial trigger point in the trapezius muscle able to cause a decrease of the pain and an increase of the cervical range of motion in asymptomatic subjects. For this, the pressure pain threshold will be measured with a algometer on the trigger point and the range of motion with a cervical goniometer.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in pressure pain threshold | Is defined as the minimum force applied which induces pain on myofascial trigger point. Pressure will be applied with algometer | At the beginning, immediately after intervention and at 72 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in cervical range of motion | Cervical range of motion is measuring movement around this segment of the spine. Lateral flexion and rotation. Will be measured with a cervical goniometer | At the beginning, immediately after intervention and at 72 hours |
