Scapular asymmetry in patients with cervical disc herniation.

Abstract

Background: The fact that scapular asymmetry and cervical disc herniation share similar findings (e.g. forward head posture, neck pain) necessitates the assessment of scapular asymmetry in cervical disc herniation.

Objective: This comparative cross-sectional study sought to evaluate scapular asymmetry in cervical disc herniation.

Methods: The study involved 114 participants, split evenly between those diagnosed with cervical disc herniation and healthy individuals. Neck and interscapular pain were assessed using a numerical rating scale. Mechanosensitivity in the upper trapezius and suboccipital muscle insertion was measured bilaterally with an analog algometer. Forward head posture was assessed by determining the craniocervical angle. Cervical range of motion was evaluated using a goniometer, while scapular asymmetry was tested using the lateral scapular slide test. Upper trapezius tightness was visually evaluated, and pectoralis minor length was measured using a plastic angle ruler.

Results: Scapular asymmetry ratio was significantly higher in patients with cervical disc herniation (p < .05). The study group demonstrated significantly greater mechanosensitivity and limited cervical range of motion (p < .05). Neck and interscapular pain were more prominent in the study group. Pectoralis minor length, upper trapezius tightness, and craniocervical angle were similar in both groups (p > .05).

Conclusions: Scapular asymmetry is more prevalent in cervical disc herniation.
