Cervical fatigue refers to the sensation of exhaustion, heaviness, or reduced endurance of the neck muscles, which usually occurs after prolonged static strain of the cervical region. It is commonly associated with maintaining the head in the same position for extended periods during activities such as computer work, driving, or prolonged use of mobile devices.
It is caused by continuous isometric contraction of the cervical and trapezius muscles, which are responsible for supporting the weight of the head, especially when the head is maintained in an abnormal posture, such as a forward head position.
Prolonged muscle fatigue gradually leads to the accumulation of metabolic by-products within the muscles, reduced local blood circulation, and increased muscle tension. As a result, patients may experience a sensation of heaviness, neck pain, stiffness, and, in some cases, tension-type headaches.
When this condition occurs frequently or remains untreated, it may contribute to the development of chronic neck pain or aggravate pre-existing degenerative changes of the cervical spine.
Management focuses mainly on improving workplace ergonomics, taking regular breaks for neck movement, performing stretching and strengthening exercises for the cervical muscles, and applying relaxation techniques to reduce muscle tension.
