“…Among these are assuming particular postures 8 (O'Sullivan et al 2002), though this aspect is not considered a risk for the bone, muscular and articular apparatus by the Legislative Decree 81/08 (Decreto legislativo 81/08), but when these postures are incorrect (Colombini et al 1995) they may induce a sense of discomfort, fatigue and pain in a matter of a short term. A greater degeneration of the entire lumbar rachis, and particularly of the lower lumbar region, is also correlated to the handling of loads with frequent lifting, pushing and tractions, especially in absence of mechanical devices (Karahan et al 2009).…”

Aim: Chronic disorders of the musculoskeletal system, particularly low back pain (LBP), are increasing and represent a social and economic problem of growing importance, especially if correlated with working conditions. Health care workers are at higher risk of developing LBP during work shifts in the hospital. The aim of this study was to assess the prevalence of LBP among operating room nurses and to investigate the risk factors for musculoskeletal injuries in the operating room. Methods: We carried out a cross-sectional study that included operating room nurses from nine hospitals. Information on sociodemographic characteristics, lifestyle habits, working activity and psychological attitude of nurses was collected using an anonymous self-administered structured questionnaire. We evaluated the association of frequency, localization and intensity of LBP (FLI) with qualitative variables, making use of univariate analysis, chi-square test and Fisher's exact test. Multiple logistic regression analysis was performed to identify the variables that affected the FLI. The covariates included in the model were the variables that had a p < 0.25 in the univariate analysis. The significance level was fixed at p < 0.05. Results: We studied a total of 185 (60.5% male) operating room nurses with a mean age of 36.08 (SD = 7.08). The chi-square test showed that FLI is associated with age (p = 0.042), physical activity (p = 0.036) and work shift (p = 0.01). The logistic regression indicated that age >35 years vs. age <35 (OR = 2.68; 95% CI = 1.17–6.18) and diurnal work shift vs. diurnal/ nocturnal (OR = 4.00; 95% CI = 1.72–9.0) represent risk factors associated with FLI, while physical activity is a protective factor (OR = 0.47; 95% CI = 0.20–1.08). Conclusion: The data suggest that it is important to promote new programs of prevention based on professional training and physical activity among nurses and to improve the organization of work shifts in the hospital

“…This was suggested to contribute to increased strain on the spinal tissues, potentially causing further damage and injury [6,70] and also to influence the trunk muscle activity role in spinal control and stability [2,5], which may perpetuate the spinal pain disorder and contribute to more disability [2,[4][5][6]. Establishing an accurate measure of a baseline posture that patients report to be painful may be invaluable with respect to evaluating the efficacy of postural re-education interventions.…”

“…Although the link between posture and back pain is largely unknown, it has been speculated that end-of-range sitting and standing postures, that were shown to be associated with altered muscle activation patterns [1][2][3][4][5], may result in excessive loading of the passive spinal structures, eventual trauma and injury and could potentially pose a risk to the development of back pain [4,6]. Postural re-education is performed on the premise of optimizing spinal alignment to minimize stresses on the spinal structures and to improve trunk muscle efficiency in protecting the spine [7][8][9][10].…”

Preliminary study: reliability of the spinal wheel. A novel device to measure spinal postures applied to sitting and standing

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.

“…Maintaining a slumped sitting posture is a risk factor for work-related muscular disorders and is closely associated with the incidence of low back pain 11,14,15) . Dolan and Green 11) found that a prolonged slumped sitting posture resulted in impaired proprioception of "good posture" and repositioning sense.…”

In the slumped sitting posture, as compared to lumbopelvic sitting, muscular activation of the lumbopelvic region is reduced and body weight is supported by passive structures 15) .…”

Abstract. [Purpose] This study evaluated the efficacy of a newly designed chair, equipped with a Posture Sensing Composite Display Device (PSCD), for correcting poor trunk posture while performing computer work.[Subjects] We recruited 10 male workers who regularly used a computer for at least 8h per day.[Methods] Subjects performed computer work while sitting on the newly designed chair with or without the PSCD. Lumbopelvic kinematic data were recorded for 60 s following 10, 20, and 30 min of computer work using a three-dimensional motion analysis system.[Results] The newly designed chair equipped with the PSCD significantly reduced lumbar flexion, lateral bending, and rotation during computer work.[Conclusion] The PSCD may prevent work-related musculoskeletal disorders by enabling a worker to maintain an upright posture during computer work.
