The time-varying response of the in vivo lumbar spine to dynamic repetitive flexion

Age-related differences do affect postural kinematics and joint kinetics during repetitive lifting

“…These findings are consistent with Dolan and Adams (1998) and have been attributed to creep within the passive tissues of the lumbar spine (Dolan and Adams, 1998;Parkinson et al, 2004) (e.g. discs and ligaments), the magnitude of which is affected by the load lifted and rate of trunk flexion (Toosizadeh and Nussbaum, 2013).…”

Differences in symmetry of lumbar region passive tissue characteristics between people with and people without low back pain

“…(McGill et al 1994;Parkinson et al 2004;Scannell & McGill 2003) Investigators who have examined differences in end-range posterior-anterior lumbar intersegmental mobility have reported that people with LBP demonstrate greater mobility compared to people without LBP. (Kulig et al 2007) The current study examines group differences in lumbar region passive tissue characteristics during a physiological motion.…”

“…(Beach et al 2005;McGill et al 1994;Parkinson et al 2004) Investigators also have examined posterior-anterior mobility and stiffness of individual lumbar spine segments in people with and people without LBP. (Keller et al 2000;Kulig et al 2007;Lee et al 1998) To our knowledge no investigator has examined passive tissue characteristics of the lumbar region during a physiological movement in people with and people without LBP.…”

The Effectiveness of a Lumbopelvic Monitor and Feedback Device to Change Postural Behavior: A Feasibility Randomized Controlled Trial

“…15,39 A recent systematic review assessed the level of evidence for domains of cumulative postural exposure (ie, range of motion [ROM] and duration and frequency of forward flexion) as risk factors for NSLBP, and reported inconclusive results. 41 There is some indication in the laboratory-based literature that exposure to repetitive and sustained flexed posture may lead to impaired spinal muscle control, 32,33 which may increase the risk of NSLBP. 49 Additionally, posture is considered by clinicians, researchers, and ergonomists to be one of the numerous risk factors related to the development and maintenance of NSLBP.…”
