Comparative StudyA radiographic comparison of neutral cervical posture with cervical flexion and extension ranges of motion.
To radiographically assess, using a pilot study, the relationship between the neutral cervical curve and cervical segmental ranges of motion (ROM) for flexion and extension in asymptomatic subjects. ⋯ Correlation between neutral cervical posture and flexion or extension ranges of motion was only strong at the C4 and C5 vertebral levels. Generally, there was not good predictability of ROM from neutral posture as indicated by the R2 values and the standard errors of estimate. Further investigation is needed to determine if other variables, such as angle of the facet joints, may be influential in these postural-functional relationships.
