Summary

Tension neck may stem from impaired cervico-collic reflex (CCR) activation. This study found that individuals with tension neck exhibit abnormal postural responses to proprioceptive stimulation, suggesting a link to faulty proprioception.

Area of Science:

  • Neuroscience
  • Biomechanics
  • Occupational Health

Background:

  • Tension neck (TN) is a common condition, potentially linked to proprioceptive and vestibular system dysfunction.
  • The cervico-collic reflex (CCR) plays a crucial role in maintaining neck posture and stability.

Purpose of the Study:

  • To investigate the relationship between tension neck and the activation of the cervico-collic reflex (CCR) and vestibulospinal responses (VSRs).
  • To identify predictors of tension neck based on postural stability during proprioceptive stimulation.

Main Methods:

  • Recorded CCR and VSRs in 106 forest workers using vibratory stimulation of neck, lumbar, and calf proprioceptors.
  • Utilized posturography to measure VSRs and body sway during quiet stance.
  • Employed logistic regression analysis to determine predictors of tension neck.

Main Results:

  • Tension neck was present in 27% of subjects and associated with older age.
  • Subjects with TN showed excessive and prolonged body sway in response to neck and lumbar proprioceptive stimulation, unlike those without TN.
  • Postural stability during and after stimulation significantly predicted TN.

Conclusions:

  • Inadequate proprioceptive and vestibular activation of the cervico-collic reflex (CCR) may contribute to tension neck.
  • Impaired proprioception and abnormal CCR facilitation are implicated in the development of tension neck.
  • Postural instability during proprioceptive stimulation serves as a significant predictor for tension neck.
