Spinal disorders are some of the most prevalent health concerns, especially among students

Stability of the cervical spine during head and cervical movements is an important component of cervical spine function .The deep neck flexor (DNF) (longus colli, longus capitis) muscles stabilize the neck and contribute to the control of head acceleration. Weakening of these muscles can lead to its coordination, activation, overload and poor support in the cervical structures. Further causes neck pain and altered neck position.

Studies conducted on patients with neck pain have also shown activation of these muscles and reduced resistance, associated disorders and headaches. Muscle resistance should be considered as a measure of neck function or injury.

University class, staying up late can be considered a risk factor for neck pain in students.
