Evaluation of the reliability of a new non-invasive method for assessing the functionality and mobility of the spine.

UNLABELLED For the evaluation of the functionality and mobility of the spine, several methods have been developed. The purpose of this study was to estimate the test-retest reliability of the Spinal Mouse, a new, non-invasive, computer-assisted wireless telemetry device for the assessment of the curvatures, the mobility and the functionality of the spine. MATERIALS AND METHODS the test-retest reliability was evaluated in 50 adults with back or low back pain. Twenty four parameters were studied in the sagittal and frontal plane. For the characterization of the precision, the intraclass correlation coefficient and the standard error of measurement were used. RESULTS in the sagittal plane, 22 of the 24 parameters showed high and good reliability, while only two fair and poor. In the frontal plane, 17 parameters showed high and good reliability, five fair and two poor. DISCUSSION the Spinal Mouse showed excellent test-retest reliability in the sagittal plane, while a slightly inferior performance in the frontal plane, for the evaluation of curvatures, deformation and mobility of the spine.
