Core Stability Exercises Versus Scapular Stabilization Exercises on Hand Grip Strength in Patients With Chronic Myofascial Neck Pain
Chronic myofascial neck pain (CMNP) is a painful non-articular musculoskeletal neck syndrome that is a persistent and prevalent with a high incidence of recurrence rate range 30-93%.Management of myofascial trigger points were directed at its deactivation, and prevention of its recurrence. Based on mechanical kinetic chain, the upper extremity functions as a unique system of connected segments those collaborated in a harmony in order to perform daily life activities. Core stability exercises maximize motor pathways mechanoreceptors' activities, as well scapular stabilization exercises are generally recommended based on reported benefits in terms of chronic neck pain. The relationship between chronic myofascial neck pain, and hand disability is quite strong. From mechanical point of view, core stability exercises improve trunk stability in line to enhance upper extremity efficiency that facilitates hand, and pinch grasping. In addition, scapular stabilization exercises could improve both hand, and pinch grasp strength and dexterity. Therefore, this randomized clinical trial will be conducted in line to clarify the superiority of the therapeutic effects between core stability exercises, scapular stabilization exercises, and conventional physical therapy program on hand grip strength, pinch grip strength, neck pain intensity level, pain pressure threshold, and whole upper extremity functional level in patients with chronic myofascial neck pain.
