A description of normal relaxed standing postures.

A technique for the measurement of relaxed standing postures, called the Posturegram, is described. The method is inexpensive, non-invasive and is suited for clinical use. Recording is done by photography. The present study examines features of standing that were exhibited by 42 normal subjects, based upon the disposition of landmarks in the coronal and sagittal planes. Degrees of assymetry that would merit clinical attention were tentatively identified. Repeat observations, 1 week apart, of the disposition of landmarks were strongly correlated, although the lowest correlations applied to the region of the pelvis and lower trunk. Many highly significant correlations were found between the various tilts and deviations, suggesting that the analysis of postures will finally depend upon considering variables in groups rather than singly.
