“…Repetitive mechanical stress over time could promote the appearance of algogenic substances that could lead to tissue hyperalgesia [41]. Some authors have suggested that postural alterations could play a role in the development of pain through an increase in tissue mechanosensitivity [11,42]. FHP could potentially lead to a situation of tissue hyperalgesia, as shown in the present study by a reduction in PPT, which could trigger neck pain or headache depending on the adaptation capability of the central nervous system.…”

“…FHP could lead to an increase in the stress imposed on articular, muscular, and neural tissues of the neck or upper limb, which could lead to the development of pain depending on the tolerance and adaptation capability of the central nervous system [10]. It has been shown that some postural alterations like a depressed scapula can alter the mechanosensitivity of different tissues, thus decreasing their mechanical stress tolerance without evoking a nociceptive response [11]. Recently, it was found that FHP is not associated with the pressure pain threshold (PPT) measured in the upper trapezius (UT) and the articular pillars of C5-C6 in asymptomatic college students, but symptomatic subjects with FHP tended to have high PPT in the right UT [12].…”

The relationship between forward head posture (FHP) and neck pain is not clear. FHP could possibly increase the mechanosensitivity of cervical tissues, which could lead to the development of pain depending on the adaptation capability of the central nervous system. The purpose of this study was to analyse the influence of FHP in the mechanosensitivity of articular, muscular, and neural tissues related to the cervical spine. The pressure pain threshold was bilaterally measured in different muscles and nerves and the second cervical vertebrae. The cervical spine’s range of movement was also examined. The measurements were obtained from people with (n = 32) and without (n = 64) FHP. The analyses included a 2-by-2 mixed analysis of variance (ANOVA), pairwise comparisons with Bonferroni correction, and point-biserial correlation coefficients. Subjects with FHP showed a less pressure pain threshold (PPT) in all locations except for the upper trapezius and scalenus medius muscles. They also showed less extension and right-rotation range of motion. There was no association between FHP, neck pain, disability, and headache. Nevertheless, more research is needed to evaluate the relationship between FHP, tissue mechanosensitivity, and neck pain.

“…The improvement in pain in our study may partially be explained by the effects of exercises and/or taping on scapulothoracic correction, which may facilitate regaining normal patterns of muscular activity through soft-tissue attachments of the scapula to both the cervical and thoracic spine [42]. Another explanation may be attributed to the fact that altered scapular kinematics has been found to contribute to generate tissue mechano-sensitization and an eventual structural hypersensitivity [43]. Moreover, a decrease in the compressive forces on the cervical facets may have resulted in decreased neck pain [44].…”

Background: No studies are available on the effects of scapulothoracic mobilization with neck movement (MWM) on patients with neck pain and scapular dyskinesis. Objective: To investigate the effects of scapulothoracic MWM on neck pain, range of motion (ROM), and function in patients with neck pain who demonstrated scapular dyskinesis.Methods: This was a single-blind, randomized, clinical trial. Forty participants with neck pain and scapular dyskinesis were randomly assigned to one of two 2-week regimens: experimental (scapulothoracic MWM + corrective exercises + tape) or comparison (corrective exercises + tape). The visual analog scale (VAS), pressure pain threshold (PPT), cervical and scapular ROM, and Neck Disability Index (NDI) were measured at baseline, after the third session, and after the sixth session.Results: Pain decreased after the sixth session in both the experimental [mean difference: 3.1; 95% confidence interval (CI): 2.1-4.1] and comparison groups (1.8; 95%CI: 0.81-2.8). PPT and scapular ROM did not change in either group at any session. After the sixth session, the ROM of neck extension, right rotation, and right and left side bending improved significantly (p£ 0.031) in both groups, but did not reach the minimal detectable change. The NDI improved in both the experimental (7.2-10.6; 95%CI: 2.5-15.7) and comparison groups (5.9-10.3; 95%CI: 1.2-15.4). There were no significant differences between the groups in any outcome measure at any session. Conclusions: Adding scapulothoracic MWM to corrective exercises and tape over a 2-week period did not seem to add benefit for pain and function in patients with neck pain with scapular dyskinesis.Trial registration: ClinicalTrials.gov, NCT03046160.

“…The range of elbow extension movement during ULNT1 was measured with a digital goniometer (Digital Absolute Axis Goniometer, Baseline ® ). The axis of the goniometer was placed over the medial epicondyle of the elbow, the fixed arm was oriented towards the humeral head, and the movable arm was oriented towards the ulnar head [27]. Measurements of the elbow extension range of movement during ULNT have shown good reliability (ICC = 0.80-0.89) [28].…”

Musicians frequently complain of musculoskeletal pain due to high mechanical demands, with the cervical spine being the most affected. Increased neuromuscular mechanosensitivity due to repetitive mechanical stress over time has been described in neck pain patients. Nevertheless, the association between musculoskeletal pain and neuromuscular mechanosensitivity in musicians is unknown. Therefore, the aim of this study was to analyze the relationship between neuromuscular tissue mechanosensitivity and neck pain in guitarists. Guitarists with chronic neck pain (n = 70) and without pain (n = 70) were enrolled. Pain and disability were measured by the visual analogue scale and the Neck Disability Index, respectively. The pressure pain threshold (PPT) was bilaterally measured for the upper trapezius and median nerve. Finally, the Upper limb neural test one (ULNT1) was bilaterally measured. The analyses included a 2-by-2 mixed analysis of variance, pairwise comparisons with Bonferroni correction, linear regression model, and multiple linear regression. Our data showed that chronic neck pain guitarists have a lower PPT at all locations compared to healthy guitarists. They also showed a bilateral main effect for pain for ULNT1 compared to healthy guitarists. These results were not affected by the mediator variables. Finally, a relationship between upper trapezius PPT and median nerve PPT was found.
