8 luglio 2026 aggiornato da: Adnan Abdelkhalik Atwa Gharib, Cairo University

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.

Descrizione dettagliata

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?

Misura del risultato
Misura Descrizione
Lasso di tempo
Hand Grip Strength
Lasso di tempo: 1. At Baseline (Pre-procedure), 2. Post-treatment (Post 6 weeks of treatment program).
Hand-held Dynamometer (SAMMONS PRESTON, INC. Bolingbrook, IL604404989) will be used to measure it. The patient will sit on a standard height chair with no armrest with his/ her forearm in a neutral position, and shoulder in adducted and neutral rotation, with elbow flexed 90 degrees (°). The patient will be requested to squeeze the ipsilateral hand on the hand grip dynamometer handle accordingly to the ordered verbs 'i.e., one, two, three, squeeze…harder, harder'. Three measures will be conducted with one minute a break in between, then the average will be recorded in value score.
1. At Baseline (Pre-procedure), 2. Post-treatment (Post 6 weeks of treatment program).
Pinch Grip Strength
Lasso di tempo: 1. At Baseline (Pre-procedure), 2. Post-treatment (Post 6 weeks of treatment program).
The pinch gauge (FEI, White plains, NY 10602, USA) will be used to measure the pinch grip strength, it is a valid and reliable tool. The patient will sit on a standard height chair with no armrest with his/ her shoulder, elbow, forearm, and wrist in a neutral position. The patient will be requested to squeeze the thumb pad as firm as possible against the lateral aspect of index fingers' middle phalanx, while the examiner will hold the distal end of the pinch gauge. Three measures will be conducted with one minute a break in between, then the average will be recorded in a score value.

Misura Descrizione
Lasso di tempo
Chronic Myofascial Neck Pain Intensity assessment using Numerical Pain Rating Scale:
Lasso di tempo: 1. At Baseline (Pre-procedure), 2. Post-treatment (Post 6 weeks of treatment program).
Numerical Pain Rating Scale will be used to assess chronic myofascial neck pain intensity, The patient will be in a relaxed position then will be given the appendix which contains numerical pain rating scale. It involves a 0-10 scale, where 0 represents "no pain" and 10 represents "the worst pain imaginable" The patient will be instructed to place a vertical mark on the line to indicate his/her pain.
1. At Baseline (Pre-procedure), 2. Post-treatment (Post 6 weeks of treatment program).
Pressure Pain Threshold using electronic pressure algometer
Lasso di tempo: 1. At Baseline (Pre-procedure), 2. Post-treatment (Post 6 weeks of treatment program).
The electronic pressure algometer 'force one gauge model FDI' (Wagner instruments, Greenwash, CT, USA) will be used to measure it, it is a valid and reliable tool. Over trigger point recognized via jump sign clinically, a dial-style pressure algometry will be installed while a steady vertical pressure will be applied. When the patient reported only mild pain, the patient will be asked to raise hand to indicate it. Three measures will be conducted with one minute a break in between, then average will be recorded in value.
1. At Baseline (Pre-procedure), 2. Post-treatment (Post 6 weeks of treatment program).
Whole Upper Extremity Functional Level using Arabic-Q-DASH scale
Lasso di tempo: 1. At Baseline (Pre-procedure), 2. Post-treatment (Post 6 weeks of treatment program).
The whole upper extremity functional level will be evaluated using Arabic-Q-DASH it is a valid and reliable tool. The Arabic-Q-DASH is like the original questionnaire. Items have a rating scale ranged from 1 to 5. The patient will be instructed to place a score that the examiner will transform it into a value between 0 and 100. The high score indicates better hand function outcomes with exception of pain, where high value indicates more intense pain score.
