Biomechanical constraints remain major risk factors for low back pain. Results from a prospective cohort study in French male employees

Does objectively measured daily duration of forward bending predict development and aggravation of low-back pain? A prospective study

“…This may be because previous studies were based mainly on selfreported exposure or cohorts without frequent followup. Some studies report a positive association (8,10) but comparison with our study is highly challenged by the aforementioned different exposure measurements between studies (11,16). A few studies support our finding of lack of association between forward bending and LBP (12,37).…”

“…Several physical work demands are generally wellestablished risk factors for LBP (6,7), such as heavy lifting (7,8) and forward bending of the trunk (9)(10)(11). Forward bending of the trunk is a relatively frequently occurring activity, particularly among blue-collar workers (12).…”

Social support modifies association between forward bending of the trunk and low-back pain: Cross-sectional field study of blue-collar workers

“…This study therefore contradicts the general assumption that forward bending is a major work-related risk factor for LBP (11,41). For example, a systematic review reported a moderate-to-strong relationship between forward bending during work and severe LBP (11), and forward bending for ≥ 2 hours every day during work was strongly associated with LBP in a recent prospective study (47). However, a recent review from the Swedish Council on Health Technology Assessment pointed out that there are conflicting results regarding the association between forward bending and LBP (28,48).…”

Contribution of occupational factors to the incidence and persistence of chronic low back pain among workers: results from the longitudinal VISAT study

“…In an interesting repeated cross-sectional survey, Ramond-Roquin et al 26 underlined the important role on LBP of biomechanical factors such as frequent bending and driving industrial vehicles, despite the existence of psychosocial and organisational factors (working more hours than officially planned and low support from supervisors), but did not distinguish between acute, subacute or CLBP. The VISAT study emphasises the role of different categories of occupational factors on focused types of LPB and the need to take into consideration the onset time of CLBP.…”
