Studying the relationship between low back pain and working postures among those who stand and those who sit most of the working day

Abstract

A relationship between low back pain (LBP) and prolonged standing or prolonged sitting at work has not been clearly shown, despite its biological plausibility. Because sitting and standing postures vary as to duration and freedom to alternate postures, and standing postures vary as to mobility, associations between specific working postures and LBP were explored using multiple logistic regression. Associations between work factors and self-reported LBP during the previous 12 months that interfered with usual activities were examined among 4493 standing workers and 3237 sitting workers interviewed in the 1998 Quebec Health and Social Survey; 24.5% reported significant LBP. Since the same conditions can correspond to different physiological demands for sitting compared with standing workers, analyses were performed separately for the two groups. Standing without freedom to sit was associated with LBP. Different occupational physical and psychosocial factors were associated with LBP in sitting compared with standing populations.

Whole Body Vibration in Helicopters: Risk Assessment in Relation to Low Back Pain

“…In the pilot's seat there was an increased prevalence of pain, the onset of pain was quicker and the intensity was greater (11). This has been investigated by others where those sitting in a fixed position had higher incidence of LBP compared to those who were allowed to move more freely (31). That there is a link between spinal posture and LBP is therefore well established, but the mechanics and biological processes in various postures that lead to LBP are not fully understood (20).…”

Musculoskeletal symptoms among female garment factory workers in Sri Lanka

“…Quality assessment workers, for example, may stand for the entirety of their shifts (Hancock, 2005), potentially contributing to the development of lower limb, back, and shoulder pain (Tissot, Messing, & Stock, 2009). Sewing machine operators, on the other hand, are seated and bent forward while performing their work, increasing the likelihood of back, neck, and shoulder symptoms (Westgaard & Jansen, 1992;Sarder, Imrhan, & Mandahawi, 2006;Tissot, Messing, & Stock, 2009). …”

“…Such work organization factors have been found to correlate with neck, back, and shoulder symptoms, particularly among female workers (Johansson & Rubenowitz, 1994;Bildt, Alfredsson, Michélsen, Punnett, Vingård, Torgen, et. al., 2000;Tissot, Messing, & Stock, 2009;Wang, Rempel, Hurwitz, Harrison, Janowitz, & Ritz, 2009;Wang, Harrison, Yu, Rempel, & Ritz, 2010).…”

G3-3 Ergonomic Hazard Identification on Musculoskeletal Discomfort among Electronic Workers in Thailand

“…Prolonged standing has been identified as an ergonomic risk factor for body discomfort among electronic workers in this study. This has also been revealed by previous studies (Chandrasakaran et al, 2003;Chee et al, 2004;Tissot et al, 2009). Therefore, working process and posture of workers in part packaging and assembly should be investigated for related musculoskeletal discomfort.…”

“…Musculoskeletal disorders (MSDs) are considered to be a major occupational health problem and also affecting quality of work life, medical costs, efficiency at work and productivity in most workplaces (Health and Safety Executive, 2015). Industrial workers have been identified as high risk of developing MSDs (Aziz et al, 2015;Chandrasakaran et al, 2003;Chee et al, 2004;Tissot et al, 2009). Lu et al (2016) reported that manufacturing operators in Taiwan for the prevalence of MSDs was 31.8%.…”
