IONTOPHORESIS Versus Ultrasound in Mechanical Neck Pain

Study Overview
=================
Brief Summary
-----------------
to investigate the effects of Magnesium Sulphate Iontophoresis versus High Power Pain Threshold Ultrasound on pain, function and range of motion on active MTrPs found in the upper trapezius.

Detailed Description
-----------------
Myofascial pain syndrome (MPS) is a musculoskeletal chronic pain disorder that affects the majority of pain population and characterized by the presence of trigger points. MPS is usually associated with tenderness, spasm, movement limitation and referred pain . Myofascial trigger points (MTrPs) are hyperirritable taut fibers of skeletal muscle. The taut fibers within the muscle create palpable nodules that may cause local pain, and refer pain elsewhere with soft tissue examination .
