“…These findings are consistent with positive associations between flexion posture and LBP reported in literature [19,41,42]. The torsion forces that develop with combined twisting and flexion are well known [9,40], and numerous studies have identified axial twisting of the torso as a significant risk factor for occupationally-related LBP [43][44][45].…”

Lower Back Problems and Work-Related Risks in a South African Manganese Factory

et al. 2007

An analytical cross-sectional epidemiological study carried out among 109 manganese plant workers aimed to examine the prevalence and association between lower back problems (LBP) and occupational risk factors. Outcome was defined using a guided questionnaire and a functional rating index. Exposure to occupational risk factors was determined using self-reported questionnaires and workstation analyses. Multivariate logistic regression analyses indicated significant adjusted odds ratios (OR) for prolonged 90° trunk flexion (OR 2.16; CI 1.15-4.05); manual handling (1.89; 1.17-3.08); load carriage (1.54; 1.08-2.19); and lifting (4.61; 1.37-15.47). The findings openUP (August 2007) illustrate regional and occupational specifics of risk for LBP, and indicate that selfselection or adaptation to task-specific demands could possibly lead to observations of ergonomically relevant risk factors, which do not necessarily yield statistically significant associations with LBP. The findings further support multi-modal preventative approaches.

“…The percentage loss to follow-up varied between 11 [53] and 43% [31] in studies with a follow-up of B1 year [25,28,29,31,37,38,42,46,52,53,55,56], between 10 [54] and 60% [31] in studies with a follow-up [1 and B3 years [22,23,25,28,31,34,35,39,41,49,54,55] and between 12 [45] and 28% [30,44] in studies with a follow-up of more than 3 years. In studies with a follow-up of more than 15 years [24,33,43,47] percentages loss to follow-up varied between 38 [47] and 84% [24].…”

Physical activity and low back pain: a systematic review of recent literature

et al. 2011

View full text Add to dashboard Cite

The objective of the study is to systematically evaluate the available evidence on the association between physical activity (i.e. occupational load and non-occupational physical activities) and low back pain (LBP). A systematic approach was used to explore the literature between 1999 and 2009. Studies were selected for inclusion following a comprehensive search of Medline, Embase and CINAHL. The methodological quality of each study was assessed. Studies were considered to be of 'high quality' if they met the cut-off criterion of 60% of the maximum available quality score. Thirty-six cohort or case-control studies were retrieved. Heavy workload and the accumulation of loads or frequency of lifts were moderate to strong risk factors for LBP. Strong associations were found for flexed, rotated and the awkward positions of the lumbar spine. Inconsistent results were found for leisure time physical activities, sports and physical exercise. Studies focusing on daily habitual physical activities (e.g. domestic activities and commuting) in association with LBP are lacking. In conclusion, the occurrence of LBP is related to the nature and intensity of the physical activities undertaken. However, physical activities can be subdivided into separate types and intensities and the ultimate physical load is the sum of all these activities. This makes it difficult to designate one particular activity as the cause of LBP.

“…Therefore, a time limit was not included in the operational definition. Special attention in this paper is given to the lifting capacity test, because lifting is one of the most stressful items of the FCE, it is considered a risk factor for low back pain [15,16], and is deemed potentially unsafe. Additionally, lifting provides an indication of total FCE performance [17].…”

Symptom Increase Following a Functional Capacity Evaluation in Patients with Chronic Low Back Pain: An Explorative Study of Safety

Symptom increase following a functional capacity evaluation in patients with chronic low back pain Reneman, Michiel; Kuijer, W.; Brouwer, S.; Schiphorst Preuper, H.R.; Preuper, H.R.S.; Groothoff, J.W.; Geertzen, Jan H.B; Dijkstra, Pieter U. Take-down policy If you believe that this document breaches copyright please contact us providing details, and we will remove access to the work immediately and investigate your claim. Abstract Introduction: This study was performed to study intensity and duration of symptom increase following an FCE and to explore safety of an FCE. Methods: Included were 92 patients with chronic low back pain (CLBP), mean age 38.5 years, mean self-reported disability 12.5 (Roland Morris Disability Questionnaire). All patients underwent an FCE. Symptom increase was measured with a 2-item questionnaire. Operational definition for safety: no formal complaint filed and symptom increase to occur only temporarily. Results: No formal complaints were filed (n = 92). In total, 54 patients returned the questionnaire (59%; 'responders'). Of the responders, 76% reported increased symptom intensity after an FCE, ranging from 'little increase' to 'severe increase'. Symptoms of all responders returned to pre-FCE level. Duration of symptom increase of the responders ranged from 1 day to 3 weeks. Symptom increase resided to pre-FCE level within 1 week in 93% of the responders. Symptom increase was weakly related to selfreported disability (r = 0.38, p < 0.05). Except for gender, differences between responders and non-responders were non-significant. Conclusion: A temporary increase in symptom intensity following an FCE is common. Within the operational definitions of safety used in this study, assessment of functional capacity of patients with CLBP appears safe.

Flexion and Rotation of the Trunk and Lifting at Work Are Risk Factors for Low Back Pain

Abstract: Flexion and rotation of the trunk and lifting at work are moderate risk factors for low back pain, especially at greater levels of exposure.
