iPhone measurements correlated well with scoliometer measurements .
2D photography results had a moderate to high correlation with 3D topography results .
Conclusions Overall , strong levels of evidence exist for iPhone and scoliometer measurements , with a high to very high reliability and moderate to very high validity .
Limited evidence exists for aesthetic tools TRACE and AI and 2D photography .
These results indicate there are accurate and reproducible anthropometric measures that are inexpensive and applicable in therapy setting s to assess postural asymmetry ; however , these only exist for measurement in the transverse plane , despite 3D characteristics of AIS .
Abstract Purpose As accurate and reproducible measurements of spinal curvature are crucial in the examination of patients with adolescent idiopathic scoliosis ( AIS ) , this systematic review aims to report on the reliability and validity of a range of inexpensive and easily administered anthropometric methods of postural asymmetry measurement in an AIS population , to inform practice in a clinical setting .
Evaluation of segmental postural characteristics during quiet standing in control and Idiopathic Scoliosis patients.
BACKGROUND The complex skeletal deformations that accompany Idioapthic Scoliosis pose a challenge to the clinician to non-invasively discriminate Idiopathic Scoliosis patients from children with no pathology . Therefore , the focus of this study is to non-invasively evaluate the position and amplitude of displacement of the pelvis , shoulders and thorax during quiet st and ing of Idiopathic Scoliosis patients and control subjects . METHODS The quiet st and ing posture of 18 healthy adolescent females and 22 Idiopathic Scoliosis subjects was evaluated using an Optotrak 3020 position sensor over a period of 120 s , with 4 repeat trials . Outcome measures included the mean position , root mean square amplitude and range over the duration of 120 s trials for both linear and angular measures of the pelvis , thorax and shoulders . Appropriate sample times were chosen and evaluated for stability over the 120 s period , and between trial reliability was evaluated . FINDINGS There was a significant difference between groups for the mean position of the shoulder blade rotation in reference to the base of support and to the pelvis . The Idiopathic Scoliosis patients had a significantly larger root mean square amplitude of anterior-posterior displacement of the T1 and S1 spinous processes in reference to the base of support . There was no difference between the sample duration s to estimate the mean position of the body segments , however the root mean square increased significantly . INTERPRETATION This study demonstrates that postural abnormalities are evident during quiet st and ing in Idiopathic Scoliosis patients
