A novel system for the dynamic assessment of back shape

To assess the accuracy and repeatability of angle measurements, six SpineDMS© sensor strips (three systems) were repeatedly bent taut over a range of defined arcs. Measurements of spinal curvature were additionally conducted in 10 volunteers who performed flexion and extension exercises, with all results compared against reference marker data. The measurement sensors had a high accuracy and excellent repeatability (mean intraclass correlation coefficient (ICC) >0.98), with test-retest reliability ICCs of >0.98. Measurements in volunteers showed that SpineDMS© was capable of detecting the shape and movement of the human back. This study showed that SpineDMS© could be deployed as a reliable diagnostic tool for back posture, as well as movements in the sagittal plane.
