PURPOSE: This study examined the relationship between the cervical lordosis angle (CLA) and the craniovertebral angle (CVA) and between CVA and a cross-sectional area (CSA) of the cervical muscles.
METHODS: In 17 healthy college students, the CLA was measured using a posterior tangent technique. The CVA was analyzed using photographic images, and the CSA of the cervical muscles, including longus colli, longus capitis, and sternocleidomastoid, was evaluated using computerized tomography. The Pearson’s correlation coefficient was used to determine the relationship between these variables and a neck disability index.
RESULTS: The CVA correlated with the CLA and with a CSA of longus colli (r = .487, p = .047 and r = .592, p = .012, respectively). The CLA correlated with a CSA of longus colli (r = .578, p = .015).
CONCLUSION: This study clarified the relationship between the postural, structural, and muscular changes in the cervical regions. A significant correlation was observed between the CVA and a CSA of the longus colli with the CLA and between the CVA and the CSA of the longus colli.
Prescription strengthening exercises for the deep neck flexors for individuals with a forward head posture and reduced cervical lordosis are useful.
