Correlation Between Forward Head Posture and Quality of Handwriting in College Students : A Cross-Sectional Study

Increasing use of digital devices like smartphones and computers shows that most of its users exhibit incorrect posture. Hyperextension of upper cervical vertebrae and increased displacement of the cervical vertebrae to anterior part are hallmarks of forward head posture (FHP), a bad habitual neck position. It increases the strain on the tissues of the spine, especially on ligaments and facet joints of cervical spine.

The primary movement sensors of the neck are the sensory receptors of the cervical muscles. Compared to the shoulder and thigh muscles, the cervical muscles have a substantially higher spindle density. Fine motor activities are generally linked to tiny muscles with high spindle density. Human deep cervical muscles, especially the small suboccipital muscles, have been found to have a lot of spindles. Complicated proprioceptors of the neck are necessary for complicated integrative systems involving head-eye coordination, which could explain their high spindle content.

While writing , the distal joints of upper limb help in writing and the proximal joints of upper limb are involved in maintaining the position of the writing device. The rotational movement of the proximal joints is approximately proportional to the size of the writing being produced.

With increased digital device use and prolonged sitting, college students often develop poor postural habits, leading to FHP and altered craniovertebral angle (CVA). Poor posture affects upper limb function, shoulder stability, and fine motor skills, crucial for handwriting. While studies link posture to musculoskeletal disorders, limited research examines CVA’s impact on handwriting quality in college students.

Understanding this correlation can aid early detection of postural issues affecting academic skills, enabling timely interventions. Findings can help physiotherapists, educators, and ergonomists develop strategies for posture correction, improving handwriting quality and reducing musculoskeletal disorders.
