“…However, these systems are used for stationary evaluation [1,2], or are limited to measurements at only very few points [3,4] or distances [5]. The spinal mouse [6], for example, allows the measurement of back shape, but only in different static postures. The pointer of the ultrasound based Zebris system [7] delivers similar results while the markers of the Zebris system allow a stationary dynamic assessment of back shape.…”

There is an increasing awareness of the risks and dangers of exposure to radiation associated with repeated radiographic assessment of spinal curvature and spinal movements. As such, attempts are continuously being made to develop skinsurface devices for use in examining the progression and response to treatment of various spinal disorders. However, the reliability and validity of measurements recorded with such devices must be established before they can be recommended for use in the research or clinical environment. The aim of this study was to examine the reliability of measurements using a newly developed skin-surface device, the Spinal Mouse. Twenty healthy volunteers (mean age 41±12 years, nine males, 11 females) took part. On 2 separate days, spinal curvature was measured with the Spinal Mouse during standing, full flexion, and full extension (each three times by each of two examiners). Paired t-tests, intraclass correlation coefficients (ICC), and standard errors of measurement (SEM) with 95% confidence intervals were used to characterise between-day and interexaminer reliability for: standing sacral angle, lumbar lordosis, thoracic kyphosis, and ranges of motion (flexion, extension) of the thoracic spine, lumbar spine, hips, and trunk. The between-day reliability for segmental ranges of flexion was also determined for each motion segment from T1-2 to L5-S1. The majority of parameters measured for the 'global regions' (thoracic, lumbar, or hips) showed good between-day reliability. Depending on the parameter of interest, between-day ICCs ranged from 0.67 to 0.92 for examiner 1 (average 0.82) and 0.57 to 0.95 for examiner 2 (average 0.83); for 70% of the parameters measured, the ICCs were greater than 0.8 and generally highest for the lumbar spine and whole trunk measures. For lumbar spine range of flexion, the SEM was approximately 3°. The ICCs were also good for the interexaminer comparisons, ranging from 0.62 to 0.93 on day 1 (average 0.81) and 0.70 to 0.94 on day 2 (average 0.86), although small systematic differences were sometimes observed in their mean values. The latter were still evident even if both examiners used the same skin markings. For segmental ranges of flexion, the ICCs varied between vertebral levels but overall were lower than for the global measures (average for all levels in all analyses, ICC 0.6). For each examiner, the average between-day SEM over all vertebral levels was approximately 2°. For 'global' regions of the spine, the Spinal Mouse delivered consistently reliable values for standing curvatures and ranges of motion which compared well with those reported in the literature. This suggests that the device can be reliably implemented for in vivo studies of the ORIGINAL ARTICLE Eur Spine J (2004) 13 : 122-136 DOI 10.1007 Anne F.

“…Firstly, measures of spinal curvature in various postures ( Fig. 1) [11] were made using the Spinal Mouse system, a hand-held, computer-assisted electromechanical-based device. The device is guided along the midline of the spine (or slightly paravertebrally in particularly thin individuals with prominent processus spinous) starting at the processus spinous of C7 and finishing at the top of the anal crease (approximately S3); these landmarks are firstly determined by palpation and marked on the skin surface with a cosmetic pencil.…”

There is an increasing awareness of the risk and dangers of exposure to radiation associated with repeated radiographic assessment of spinal curvature and spinal movement. As such, attempts are continuously being made to develop skin surface devices for use in examining the progression and response to treatment of various spinal disorders. However, devices must be verified before use in research or in a clinical environment. The aim of this study was to examine the reliability of measurements using a skin-surface device, the Spinal Mouse on 30 healthy volunteers. Spinal curvature was measured with the Spinal Mouse during standing, flexion, and extension (each five times by each of two examiners). The method was calibrated by a ZEBRIS ultrasound-based measuring method with WINSPINE software commercially available, and the measurement error rate of the method was determined by statistical calculations. On the basis of calibration and error calculations it could be established that the accuracy and the reproducibility of the method were appropriate, because the maximum value of intraobserver variation is 0.97 degrees (18.8%), that of interobserver variation is 1.54 degrees (27.1%). A second way of verifying the method is to specify the difference between the angles determined by the two methods. The maximum value of the average difference is 1.62 degrees (26.6%).
