Near-Infrared Spectroscopy in Myofascial Pain Syndrome

Study Overview
=================
Brief Summary
-----------------
Myofascial pain syndrome is a regional pain syndrome accompanied by sensorial, motor and autonomic symptoms . myofascial trigger points are most frequently detected in the upper trapezius, levator scapula, and axial postural muscles such as rhomboid major. Myofascial pain syndrome is characterized by active myofascial trigger points in the form of focal hyperirritable nodules palpated in the tight band of the muscle . Alteration of tissue vascularization could limit or prevent th may cause adhesions, contractures and pain. As a result of decreased blood flow, tissue oxygenation may decrease.

Detailed Description
-----------------
In this study, it will be tried to determine the role of muscle tissue oxygenation in the activity and diagnosis of the disease in myofascial pain syndrome.
