“…The former was used since in recent years the CMC is becoming a standard for the measure of the repeatability of waveforms [13,15,16,21,26,39]. The latter was used instead to enable the comparison of the results of this study with those reported in [24] about clavicle-humeral and scapulo-humeral rhythm.…”

A clinical motion analysis protocol was developed to measure the coordinated movements of shoulder-girdle and humerus (girdle-humeral rhythm--GD-H-R) during humerus flexion-extension (HFE) and ab-adduction (HAA), through an optoelectronic system. In particular, the protocol describes the GD-H-R with 2 angle-angle plots for each movement: girdle elevation-depression and protraction-retraction vs HFE, and vs HAA. Each of these plots is further divided in two subplots, one for the upward and one for the downward phases of the movement. By involving 11 participants and 2 operators, we measured the protocol's inter-operator reliability which ranged from very-good to excellent depending on the angle-angle plot (median values of the inter-operator coefficient of multiple correlation for the angle-angle plots higher than 0.94). We then computed the subjects' average control patterns, together with statistically meaningful prediction bands. +/-1SD confidence bands were also computed and their width ranged from +/-0.5 degrees to +/-4.6 degrees. Based on these results we could conclude that the method is robust and able to identify even limited differences in the GD-H-R.

“…In recent years a number of devices have been developed to analyse spinal posture outside the laboratory (Donatell et al 2005, Dean and Dean 2006, Horton and Abbott 2008. Spinal posture analysis is now possible using accelerometers (Bazzarelli et al 2001, Nevins et al 2002, Wong and Wong 2008, gyroscopes (Lee et al 2003), strain gauges and/or optical sensors (Donatell et al 2005, Dean andDean 2006) and even sensing fabrics (de Rossi et al 2003, Walsh et al 2006. Recent reviews have highlighted that, despite the potential of such devices, there is a lack of empirical data supporting their use (Wong et al 2007, Hermens andVollenbroek-Hutton 2008).…”

The BodyGuard TM is a spinal position monitoring device that can monitor posture in real time, both inside and outside the laboratory. The reliability of this wireless device was examined in 18 healthy participants during usual sitting and forward bending, two tasks that are commonly provocative in NSCLBP. Reliability was determined using intraclass correlation coefficients (ICC), the standard error of measurement (SEM), the mean difference and the minimal detectable change (MDC90). Betweenday ICC values ranged from 0.84 to 0.87, with small SEM (5%), mean difference (59%) and MDC90 (514%) values. Inter-rater ICC values ranged from 0.91 to 0.94, with small SEM (4%), mean difference (6%) and MDC90 (9%) values. Between-day and inter-rater reliability are essential requirements for clinical utility and were excellent in this study. Further studies into the validity of this device and its application in clinical trials in occupational settings are required. Statement of Relevance:A novel device that can analyse spinal posture exposure in occupational settings in a minimally invasive manner has been developed. This study established that the device has excellent between-day and inter-rater reliability in healthy pain-free subjects. Further studies in people with low back pain are planned.

Additionally, these techniques are static in nature, as they measure end-points of motion, thereby posing problems for the evaluation of kinematic parameters, such as spinal range of motion (ROM) and center of rotation, in the recording of dynamic spinal movement patterns 7,[11][12][13] . Tape measurement is utilized to assess spinal movement in the frontal plane, but cannot assess quantitative results by degrees 2) .…”

Abstract.[Purpose] The purpose of this study was to compare the total segmental range of motion (ROM) of the thoracic-lumbar-sacral spine during multidirectional trunk movements between elderly subjects with degenerative spine disease (DSD) and healthy young adults.[Subjects] Twenty-five elderly subjects with DSD and 11 healthy young adults were recruited for this study.[Methods] Subjects performed five trunk movements, including forward flexion (FF), right and left anterior-lateral bending (Rt. and Lt. ALB), and right and left lateral bending (Rt. and Lt. LB).[Results] The total segmental ROM of FF, Rt. and Lt. ALB in the sagittal plane, and Rt. and Lt. ALB in the horizontal plane was significantly different between the groups. [Conclusion] We suggest that the decreased total segmental ROM resulted from degenerative joint structures, particularly facet joints, vertebral bodies, and discs. The present findings add to the evidence in support of a relationship between degenerative changes and threedimensional spine kinematics in the elderly population with DSD.
