Intrarater and interrater reliability of photographic measurement of upper-body standing posture of adolescents.
The purposes of this study were to determine the intrarater and interrater reliability of a photographic measurement of the sagittal postures of the cervical spine and shoulder, quantitatively characterize the postural alignment of the head and shoulders in the sagittal plane of Portuguese adolescents 15 to 17 years old in natural erect standing, and analyze differences in postural angles between sexes. ⋯ Forward head posture and protracted shoulders were common postural disorders in adolescents 15 to 17 years old, with females revealing a lower mean cervical angle. The intrarater and interrater evaluation of standing sagittal posture of the cervical spine and shoulders by photogrammetry was reliable.

The effect of cervical spine manipulation on postural sway in patients with nonspecific neck pain.
This crossover study aimed to determine whether a single high-velocity, low-amplitude manipulation of the cervical spine would affect postural sway in adults with nonspecific neck pain. ⋯ This study failed to show evidence that single manipulation of the cervical spine influenced postural sway. Given the ability of the postural control system to reweight the hierarchy of sensory information to compensate for inadequacies in any 1 component, it is possible that any improvements in the mechanisms controlling postural sway elicited by the manipulative intervention may have been concealed.
