Relationship between cervical proprioception and deep neck flexor endurance in subjects with forward head posture: A pilot study

Abstract

Forward head posture, one of the most common abnormal head postures, is a postural head-on-trunk misalignment, which is defined as a head that is positioned anterior to a vertical line of gravity. It is a common postural variation in people of all ages, from childhood to old age and has been suggested to affect the cervical muscles and restrict neck movement, and impair cervical proprioception. The objective was to find the relationship between cervical joint position sense with deep neck flexor endurance in subjects with Forward Head Posture. 20 subjects with forward head posture (22- 55y old) were included in the study. The forward head posture was assessed by the craniovertebral angle, the error value of the cervical position sense was evaluated using the head repositioning accuracy test, neck flexor endurance test for the endurance functionality of cervical flexors. Karl pearson correlation coefficient was calculated between craniovertebral angle and head repositioning error. A strong negative correlation was found between craniovertebral angle and head repositioning error (p
