“…The standing postures were thought to yield more comparable data. The 33°mean standing thoracic kyphosis with standard deviation (SD 11°) and 35°mean standing lordosis (SD 11.9°) measures obtained by the spinal wheel in this study are comparable with the 33°-36°kyphosis and the 28°-32°lordosis measures in previous studies [33,[56][57][58][59]. Ng et al [17] demonstrated lower values of lumbar lordosis (24°-28°) which could be related to measuring only male subjects with arguably less pronounced standing lordosis [17].…”

“…Thoracic curvature measures demonstrated consistently better intra-, inter-and test-retest reliability compared to lumbar curvature measures with the highest errors in sitting lumbar curvatures. This observation was also made by Leroux et al [58] who reported ICC of 0.94 for kyphosis and 0.91 for lordosis with errors of 5°and 6°, respectively, when comparing radiographic and non-invasive stereographic techniques [58]. Relatively large lumbar spine movement in sagittal plane, with rather small contributions from rather more rigid thoracic region [64], could be associated with larger measurement error as measurement errors tend to increase with increased magnitude of the measured variable [65].…”

Postural re-education is an integral part of physiotherapy management in patients with back pain. Although the link between posture and back pain is largely unknown, postural re-education is performed on the premise of optimizing spinal alignment to minimize stresses on the passive structures of the spine, to facilitate optimal muscular support and thus to prevent possible damage and further pain. A reliable and clinically meaningful measurement of spinal postures to monitor such interventions remains challenging. This study evaluated within-day (intra-tester, inter-tester) and between-day (test-retest) reliability of a novel spinal wheel device measuring thoracic and lumbar postures during sitting and standing. 17 healthy volunteers (age 39.5 ± 5.4, BMI 25 ± 9.2; 9 males) were measured three times, by three testers, on two separate occasions (1 week apart). The angular change between C7 and T12 and between T12 and S1 provided thoracic and lumbar curvatures, respectively. Intra-class correlation coefficient (ICC) with 95% confidence intervals and typical error were calculated. Excellent reliability was demonstrated with intra-tester ICCs between 0.947 and 0.980 and typical error between 1.7°and 3.7°and intertester ICCs between 0.949 and 0.986 and typical error between 2.0°and 4.7°. Test-retest reliability was high with ICCs 0.719-0.908 and typical error between 4.0°and 7.4°. In conclusion, the spinal wheel demonstrated excellent within-day and high between-day reliability. The device may be used in conjunction with 2D camcorder to provide clinically useful visual evaluation of postures for assessment, intervention monitoring, and feedback during postural re-education.

“…Leroux and Zabijek compared measurements of thoracic kyphosis; analysis of the results showed high correlation between the above methods. In the case of thoracic kyphosis the correlation coefficient was 0.89, while for lumbar lordosis it was slightly lower, at the level of 0.84 [29]. Saad et al found high compatibility and repeatability of results in studies comparing values of Cobb angle, measured with photogrammetric technique and in X-ray examination [19,30].…”

Purpose The purpose of the study was to investigate correlations between parameters of anteroposterior spinal curvatures in the sagittal plane, measured with the use of photogrammetric technique and inclinometer in healthy elderly women. Methods Randomized study involved 50 females, ranging from 50 to 70 years of age (mean 62.26 ± 6.94); mean body mass index (BMI) 27.69 ± 4.79. The examined parameters included angle of inclination in lumbosacral spine (ALFA), thoracolumbar transition (BETA), upper thoracic segment (GAMMA), angle of lumbar lordosis (LLA) and thoracic kyphosis (TKA). Results obtained with gravitational inclinometer were compared with those identified with photogrammetry method. Statistical analyses were performed with Mann-Whitney U test, regression analysis and Bland-Altman analysis. Results In Mann-Whitney U test, with correction due to continuity, no statistically significant differences for any variable were found. Regression analysis was significant only for the variable of BETA angle. Bland-Altman coefficient for the respective angles was: ALFA 2.0%, BETA 4%, GAMMA 0%, LLA 2% and TKA 0%. Conclusions The results acquired with gravitational inclinometer and with photogrammetric technique are comparable, as the parameters of anteroposterior spinal curvatures acquired with these two methods are found to be compatible in the case of measurements of lumbar lordosis and thoracic kyphosis.

“…In some of the mentioned studies 3,7,8 , the methods for evaluating the pelvic tilt angle was indirect, and recent studies [9][10][11] , even though they did not show any specific data on pelvic positioning, have demonstrated that the determination of the balanced position of some body segments, indirectly measured through observations, had acceptable correlations with radiographic imaging. In these studies [9][10][11] , individuals were observed using photographs taken at several moments with skin markers positioned over certain bone prominences.…”

Influences of the extensor portion of the gluteus maximus muscle on pelvic tilt before and after the performance of a fatigue protocolInfluência da porção extensora do músculo glúteo máximo sobre a inclinação da pelve antes e depois da realização de um protocolo de fadiga AbstractIntroduction: There is a lack of data in the literature for determining the influences of the extensor portion of the gluteus maximus muscle on pelvic tilting and, thus, on lumbar stability. Objectives: To assess the influences of the extensor portion of the gluteus maximus muscle on pelvic tilt. Methods: Ten healthy young subjects were recruited, with a body mass index (BMI) below 24.9 kg/m 2 and leg length discrepancy below 1 cm. The BMI, pelvic perimeter and lower-limb lengths were assessed and, subsequently, the degrees of hemi-pelvic tilt and asymmetry between them were analyzed using lateral view photographs of the subjects in a standing position, using SAPO (Software for Postural Assessment). Next, fatigue was induced in the extensor portion of the gluteus maximus muscle on the dominant side, and after that the hemi-pelvic tilt and the asymmetry between the hemi-pelvises were reassessed. The Pearson r and Student t tests were conducted at the significance level of α=0.05. Results: There were no significant correlations between the confounding variables and asymmetry of the hemi-pelvic angles. There were significant changes in the hemi-pelvic angle of the dominant side (t=3.760; p=0.004). Conclusions: Fatigue in the extensor portion of the gluteus maximus muscle can generate increases in the tilt angle of the ipsilateral pelvis.Key words: gluteus maximus; fatigue; pelvic tilt. ResumoIntrodução: Há carência na literatura de dados que determinem qual a influência da porção extensora do músculo glúteo máximo na inclinação da pelve no plano sagital e, portanto, na estabilidade lombar. Objetivos: Verificar a influência da porção extensora do músculo glúteo máximo sobre a inclinação da pelve. Métodos: Foram recrutadas 10 voluntárias jovens, saudáveis, com índices de massa corpórea (IMC's) menores que 24,9 kg/m 2 e com dismetria real de membros inferiores (MMII) inferior a 1 cm. Foram avaliados o IMC, o perímetro pélvico e o comprimento dos MMII e, posteriormente, os graus de inclinação das hemipelves e a assimetria entre elas pela análise de uma fotografia em perfil ortostático usando o SAPO (Software para Avaliação Postural). Em seguida, a porção extensora do músculo glúteo máximo do lado dominante foi induzido à fadiga, após a qual foram determinadas novamente a inclinação das hemipelves e a assimetria entre elas. Testes de Pearson r e teste t de student foram realizados no nível de significância α=0,05. Resultados: Não houve correlação entre as variáveis de confusão e a assimetria dos ângulos das hemipelves. O ângulo da hemipelve apresentou modificação significativa do lado dominante (t=3,760; p=0,004). Conclusões: A fadiga da porção extensora do músculo glúteo máximo pode gerar um aumento do ângulo de inclinação da pelve homolatera...
