Overview
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.
Description
Chronic myofascial neck pain (CMNP) is a painful non-articular musculoskeletal neck syndrome that is a persistent and prevalent with a frequently reported myofascial trigger points (MTrPs) at upper trapezius with a reported prevalence of up to 93.75%. Individuals with upper trapezius MTrPs would have an overall upper extremity muscular strength reduction that ultimately resulting in decline hand grip strength. positive relation between core endurance and hand grip strength. That finding may be explained by the fact that the core region exhibits an anatomical, and biomechanical interconnection with the extremities, characterized by a prominent muscular linkage. Both core and scapular stabilization exercises has been addressed as one of the most evidence-based modalities. core acts as a the central most part of the kinetic chain, or a double walled cylinder with abdominals in front, multifidis as back, diaphragm as a roof, pelvic floor at the bottom. Where upper extremities connect with core, and attached extremities articulations that transfer energy from torso proximally to extremities' parts distally during functional activities . Scapular stability represents a vital role in terms of whole upper extremity functioning. The research gap to answer the question; Are there any significant differences 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?
