“…More novel devices are now often portable and thus offer the possibility to collect dynamic changes in upper body movements. Here, the collection of data using the 3D-SpineMoveGuard [9] and inertial measurement units [10], which are based on single sensors attached to the skin, are practicable but do not allow conclusions to be drawn on spinal shape. Other measurement tools such as the CA-6000 [11], fiber-optic sensors [12] and the lumbar motion monitor [13] are not suitable for assessing the conditions during normal activities of daily living due to their bulky construction or not being portable.…”

Purpose The diagnosis of low back pain pathology is generally based upon invasive image-based assessment of structural pathology, but is limited in methods to evaluate function. The accurate and robust measurement of dynamic function may assist in the diagnosis and monitoring of therapy success. Epionics SPINE is an advanced straingauge measurement technology, based on the two sensor strips SpineDMS system, which allows the non-invasive assessment of lumbar and thoraco-lumbar motion for periods of up to 24 h. The aim of this study was to examine the reliability of Epionics SPINE and to collect and compare normative data for the characterisation of spinal motion in healthy subjects. Furthermore, the identification of parameters that influence lumbar range of motion (RoM) was targeted. Methods Spinal shape was measured using Epionics SPINE in 30 asymptomatic volunteers during upright standing, as well as maximum flexion and extension, to check intra-rater reliability. Furthermore, back shape was assessed throughout repeated maximum flexion and extension movements in 429 asymptomatic volunteers in order to collect normative data of the lordosis angle and RoM in different gender and age classes. Results The lordosis angle during standing in the healthy collective measured with Epionics SPINE was 32.4°± 9.7°. Relative to this standing position, the average maximum flexion angle was 50.8°± 10.9°and the average extension angle 25.0°± 11.5°. Comparisons with X-ray and Spinal Mouse data demonstrated good agreement in static positions. Age played a larger role than gender in influencing lumbar posture and RoM. Conclusions The Epionics SPINE system allows the practical and reliable dynamic assessment of lumbar spine shape and RoM, and may therefore provide a clinical solution for the evaluation of lower back pain as well as therapy monitoring.

“…They showed that results from triaxial accelerometer measurements of trunk flexion and lateral bending could be accurate to within 5 • . Wunderlich et al recently developed a measurement system using an inclinometer and ultrasound measurements to calculate spinal motion in bending and axial twist [16], and they state that there is currently no "gold standard" to assess spine movements, though they mention 3D motion capture systems as a viable option. Ultimately, for this study a 16-camera Vicon MX40 motion analysis system (Vicon, Oxford, UK) was used to track the 3D coordinates of reflective markers placed on the subjects and orthosis.…”

A traditional spinal orthosis in conjunction with a hip-knee-ankle-foot orthosis (HKAFO) improves posture in persons with paraplegia during standing and walking. It also limits the wearer's range of motion when worn during other activities, such as vehicle transfer or sitting and reaching for objects. In order to regain full torso flexibility the user would need to remove the spinal orthosis which can be arduous and time consuming. A Convertible Spinal Orthosis (CSO) that allows the user to switch between Locked rigid torso support and Unlocked free motion has been designed, fabricated and tested. It shows promise for increasing functionality, wear time and subject comfort. Analysis of movement has been performed with an able-bodied and a paraplegic subject wearing a rigid spinal orthosis, the CSO in both states, and without any bracing. Configuration state had the most impact on lateral bending. Mean values for the paraplegic subject of 27 • , 38 • , 48 • , and 48 • and for the able-bodied subject of 22 • , 26 • , 48 • , and 45 • were found for lateral bending of the upper torso relative to the thighs in the Rigid, Locked, Unlocked, and No-Brace states, respectively.

“…In the last decade, several methods have been developed to perform accurate postural evaluations during standing. Technological advancements have enabled the use of highly reliable and easy-tooperate tools, such as X-ray scanners (16,17) and computerized photographic systems (18), to assess postural asymmetry. X-ray imaging is the standard method of assessing spinal alignment because it provides clear images of anatomical landmarks.…”

KEYWORDSpelvic asymmetry, low back pain, photographic assessment, pelvic posture 3 Abstract Background Empirical evidence that identifies the pelvic asymmetry in which movement plane that contribute to non-specific chronic low back pain (NCLBP) is currently lacking.Objective To establish the reliability of the Global Postural System (GPS) in assessing pelvic asymmetry and identify the association between pelvic asymmetry parameters and the occurrence of NCLBP in young adults.Design A cross-sectional, regression study.Methods People who aged between 18 and 30 and were diagnosed with NCLBP were recruited.Healthy individuals who were matched for age, gender, and education level were recruited as controls and for the reliability analysis. Reliability was assessed by the ICC (3, k), standard error and minimal detectable difference. Bivariate correlation analysis and logistic regression analysis were used to determine the risk factors.Results Twenty-eight healthy participants and 28 people with NCLBP were recruited. Moderate to excellent ICCs were observed for the inter-rater and intra-rater reliability of most postural parameters.The bivariate correlation analysis indicated that age, body mass index and pelvic asymmetry parameters were related to the occurrence of NCLBP. Pelvic angle asymmetry (odd ratio=1.17), and asymmetry of the distance between the posterior superior iliac spine and the floor (odd ratio=1.21)were significant risk factors of NCLBP.Limitation This study did not explore the causal relationship between pelvic asymmetry in the sagittal plane/pelvic asymmetry in the transverse plane and the occurrence of NCLBP. The interpretation of the results may not be generalized beyond the sample population.Conclusions The GPS is a reliable method to assess pelvic asymmetry in a clinical setting. The pelvic asymmetry parameters obtained from the GPS are likely to assist in the early identification of the potential occurrence of NCLBP.
