Muscles that Move the Head

7.6K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Area of Science:

  • Ergonomics
  • Biomechanics
  • Occupational Health

Background:

  • Prolonged computer use is prevalent in modern workplaces.
  • Sedentary work postures can lead to musculoskeletal issues.
  • The upper cervical region's role in sustained computer work is not fully understood.

Purpose of the Study:

  • To investigate the impact of sustained computer work on cervical flexion.
  • To specifically assess changes in the upper cervical region's range of motion.
  • To determine if prolonged computer use affects the ratio of upper cervical to total cervical flexion.

Main Methods:

  • Recruited 11 sedentary workers with at least 4 hours of daily computer use.
  • Measured total cervical flexion, upper cervical flexion, and their ratio.
  • Measurements were taken before and after a 1-hour period of computer work.

Main Results:

  • Total cervical flexion showed no significant pre- vs. post-work difference.
  • Upper cervical flexion significantly decreased after 1 hour of computer work.
  • The ratio of upper cervical to total cervical flexion also significantly decreased.

Conclusions:

  • Sustained computer work negatively affects cervical flexion, particularly in the upper cervical region.
  • This suggests a localized impact on the upper cervical spine due to prolonged computer use.
  • Findings indicate a need for ergonomic interventions to mitigate these effects.
