Sternocleidomastoid Muscle and Head Position: How to Minimize Muscle Tension

OCCUPATIONAL APPLICATIONSThe coronavirus disease pandemic has changed the setting of many jobs, forcing people to switch to remote work. In turn, telework is associated with an increased risk of musculoskeletal disorders, as it is difficult to ensure an ergonomically correct work environment at home. Complaints of headaches, neck pain, and dizziness are reported by both young and old people. One of the reasons for such complaints might be an incorrect head position and prolonged tension in the neck muscles that is directly correlated with a spatially misaligned computer monitor and peripherals. We examined biomechanical parameters of the sternocleidomastoid muscle and found that it is possible to reduce tension in this muscle by keeping the head in an appropriate angular range to minimize potential health risks.
