“…Such a change in muscle spindle inflow would adversely affect postural control. We agree with the implication of a previous study 15) , that localized neck extensor muscle fatigue affects the mechanisms of postural control by presenting atypical sensory information from muscle spindles thereby eliciting postural instability. In the present study, neck muscle fatigue elicited postural instability in the AP direction and an increase in sway velocity.…”

“…Neck muscle fatigue can be considered as neck disturbances and it is likely to change somatosensory inputs. The alteration in proprioception information immediately interacts with visual and vestibular inputs leading to postural instability 14,15,41) . The mechanism of muscle fatigue is unlike that of muscle vibration.…”

“…Neck muscle fatigue is reported to influence postural control and may disturb subjective postural reference. Neck extensor muscle fatigue increases body sway, in addition to changing body direction [14][15][16][17] . A study reported that after 5 minutes of intense contraction of approximately 35% of maximal voluntary contraction of the dorsal neck muscles the body sway increased during quiet standing 15) .…”

Abstract. [Purpose] This study investigated postural stability and visual vertical perception of healthy middleaged subjects before and after induction of dorsal neck muscle fatigue.[Subjects] Fourteen subjects (3 males, 11 females) were recruited from the community.[Methods] To induce neck extensor muscle fatigue, participants pushed their heads against a myometer. The average center of pressure (COP) displacement in the medial-lateral (ML) and anterior-posterior (AP) directions and average sway velocity were measured on a force platform, and the error in visual vertical perception was measured using the rod and frame test.[Results] The average COP displacement in the AP direction and average sway velocity were significantly different between before and after induction of neck muscle fatigue. No difference in the average COP displacement in the ML direction or errors in visual verticality perception was observed before and after neck muscle fatigue. [Conclusion] In the presence of visual input, dorsal neck muscle fatigue induced postural instability, but not visual vertical misperception. After isometric or repetitive neck extensor muscle contraction for a long period, taking a rest for a while before changing posture from sitting to standing is recommended for workers, to avoid an increase in postural sway in standing, which may lead to an accidental fall.

This study aimed at investigating the effects of a novel neck balance system (NBS), which is a baseball cap with counterweights in the occipital part, on neuromuscular fatigue of neck muscles during and after a full‐range repeated neck flexion‐extension task. Surface electromyography (sEMG) of sternocleidomastoid (SCM) and semispinalis capitis (SC) muscles was recorded in 15 healthy individuals during full‐range flexion‐extension movements of the neck lasting 5 min at a fixed pace (1 Hz), with or without NBS. Maximal isometric force and sEMG were recorded before and after the fatiguing task. During the fatiguing task, the SC muscle showed a higher decline in amplitude of sEMG with NBS than without NBS, while no differences in the SCM muscle emerged between the two conditions. Maximal isometric force of both neck flexor and extensor muscles decreased significantly after the fatiguing task, both with NBS (p < .05) and without NBS (p < .05), with no differences between the two conditions. In conclusion, adopting the NBS promotes an increase of the activation of neck extensor muscles, possibly leading to earlier decline of the neuromuscular performance and to diminished ability to actively stabilize neck structures. For these reasons, the adoption of the NBS during dynamic, fatiguing contractions may not be appropriate.

BackgroundNeck pain is one of the most burdensome chronic musculoskeletal problems globally. Impaired proprioception is associated with Chronic Nonspecific neck pain as the structures of the cervical spine are crucial for proprioception and balance. There is a paucity of literature examining objective measures of balance and postural sway in patients with Nonspecific neck pain.MethodsThis study was observational and consisted of 126 samples (63 cases and 63 controls who were recruited using convenience sampling. The demographics of the samples were collected and the postural and balance impairment was assessed using Biodex Balance SD. Mean, Median, and SD were obtained and the inferential analysis was done using the Whitney U Test and the level of significance was accepted at p < 0.05.ResultsThe subjects with neck pain showed had a lower static stability index, static sway index, static stability index‐ forward backward and static sway index lateral scores than the normal counterparts. There are significant differences in the overall static stability index, (p < 0.001). There was a significant difference in static sway index(p = 0.003), and static stability index lateral (p = 0.004). There was no significant difference for static sway index forward and backward (p = 0.550) and lateral sway index (p = 0.711).ConclusionSubjects with neck pain showed had a lower static stability index, static sway index, static stability index‐ forward backward and static sway index lateral scores than the normal counterparts and there was a significant difference between the static sway and static stability index in forward and backward directions as well as in lateral direction. These findings may help to assess the specific balance parameters and address the underlying causes of balance issues in patients with neck pain and also provide a comprehensive care to the patients.Clinical Trial RegistrationThe trial was registered with CTRI India with registration number: CTRI/2022/07/044222.
