Background:
Postural asymmetry is natural and expected during postural assessment. Besides, there are conditions that exacerbate the difference between right and left side views, such as Idiopathic Scoliosis (IS). However, the photogrammetric postural assessment on sagittal plane is usually performed using only one side view. This study aimed testing if there are differences between the right and the left-side views in photogrammetric postural assessment of adults on sagittal plane.
Methods:
Patients with and without scoliosis were assessed and were grouped into Control Group (CG) and Positive Adam's test Group (PAG) according to Adam's forward bending test. After screening, participants were assessed using the right and the left-side views according DIPA© protocol. Descriptive and inferential analysis were made using Paired t-Test and Independence Chi-square Test (χ2).
Results:
Significant differences were found between right and left side views to knee angle and head position angle to overall sample. The mean difference was low, about 1° on head position and 2.6° on knee angle and did not affect the classification of body segments.
Conclusion:
We conclude that the postural assessment on sagittal plane of adults without IS can be performed using only one side view, becoming the photogrammetric postural assessment an easy-to-use tool.
