Iphone app use to Cobb angle in adolescent idiopathic scoliosis: Does this apply?

Abstract

<sec><title>OBJECTIVE:</title><p> To validate a new method of measuring the Cobb angle for scoliosis from the mobile app CobbMeter to facilitate the evaluation and measurement in clinical practice.</p></sec><sec><title>METHODS:</title><p> Five observers with minimum experience of two years in the field performed radiographic measurements of Cobb angle in 24 radiographs of patients with adolescent idiopathic scoliosis through the CobbMeter. Observers performed serial measures on the images with the application, which were repeated after one month. The most experienced appraiser of the group, after measurements were made through the application, determined the Cobb angle in each radiography by the traditional method.</p></sec><sec><title>RESULTS:</title><p> The mean standard deviation by comparing the angles electronically and manually measured had no clinical significance. Although 40% of electronic measurements are outside the confidence interval when compared to manual measurements, this difference was insignificant in clinical practice.</p></sec><sec><title>CONCLUSIONS:</title><p> The CobbMeter is another alternative for measuring Cobb angle in scoliosis.</p></sec>

Reproducibility and Equivalence of Cobbmeter Application in the Sagittal Evaluation of the Spine

“…Therefore, the use of the cellular application insures measurements that are comparable and correlated to those acquired using the traditional measurement acquisition method proposed by Cobb. 23 Other studies have already studied the use of smartphone applications to measure vertebral parameters, whether coronal 24,25 (Cobb angles in scoliosis) or sagittal 15 (kyphosis). Unlike earlier studies, this work measured spino-pelvic sagittal angles, which involve not only vertebral plateau lines, but also imaginary lines drawn between two anatomical points (such as for example the line that joins the center of the femur heads and the center of the S1 plateau).…”

“…Regarding the US applications, although they have used sensors embedded in smartphones (i.e., accelerometer and gyroscope), they varied in relation to the measurement methods used by the assessors. Some studies [68][69][70][74][75][76]79,82,92] used applications to analyze radiographs of the spine. For example, the method proposed by Allam et al [76] positioned radiographs in the vertical plane on a backlit X-ray reader box.…”

A mobile application tool for standing posture analysis: development, validity, and reliability

“…The review of Moreira et al investigated the studies regarding posture assessment tools between the year 2012 and 2020, and they reported 13 mobile apps for assessing posture [12]. A majority of these apps were developed specifically for analysis of spinal orientation such as lordosis, kyphosis, scoliosis postures, and Cobb angle [18][19][20]. Furthermore, 11 of 13 apps were classified as sensor-based (accelerometer or gyroscope) apps that have diverse approaches such as using assessment of radiographs [21] or direct contact with the body of patients [12,22].…”
