Investigation of self-reported of low back pain (LBP) over the last month and associated health-related quality of life (HRQoL) in a sample of a community-dwelling population aged ≥65. ⋯ LBP appears to be a more permanent condition in the older groups. LBP may be a part of the definition of a subgroup of elderly at risk of becoming frail in relation with higher levels of functional limitations, psychological difficulties and social restrictions, hence globally impaired HRQoL.

The aim of this study was to evaluate the lumbar trunk parameters by MRI and investigate their association with chronic low backache. ⋯ Tendency of smaller trunk musculature CSA may be a cause or a result of chronic LBP. A unique pattern of larger CSA at L3-L4 and L4-L5 disc levels and smaller CSA at L5-S1 of Rectus abdominis muscles is observed in LBP patients compared to healthy persons. Differences in disc angles and CSA of disc at L3-L4 and L4-L5 levels between the two groups signify that these may be the predisposing factors leading to LBP due to abnormal load/stress transmission and precipitating early degenerative changes in the disc.

The study reports the feasibility of implementing routine registry data collection and sustaining a high rate of data capture within a secondary care spinal osteopathy service, using the Spine Tango Conservative registry data collection tool (STC) with multiple patient-reported outcome measures (PROMs): Oswestry Disability Index (ODI), Neck Disability Index (NDI), COMI Low Back Conservative, COMI Neck Conservative and EQ-5D-3L. ⋯ Our analysis shows that a high rate of data capture can be sustained in a clinical setting using the STC and multiple PROMs. However, increasing the burden of data collection on patients and practitioners was associated with increased data loss. We describe measures taken to reduce data loss in the future and to increase the efficiency of the data collection project.

It is well established that posterior spinal surgery results in damage to the paraspinal musculature. The effects of such iatrogenic changes on spinal loading have not been previously investigated, particularly at levels adjacent to a spinal fusion. Therefore, the objective of this study was to investigate the effect of simulated muscle damage on post-operative spinal loading at the adjacent levels to a spinal fusion during upright postures using a mathematical model. ⋯ The results suggest that the paraspinal muscles of the lumbar spine play an important role in adjacent segment loading of a spinal fusion, independent of the presence of rigid spinal instrumentation.

To examine the influence of volitional preemptive abdominal contraction (VPAC) and recurrent low back pain (rLBP) on trunk mechanics and neuromuscular control during a symmetric lifting task. ⋯ Our results provide evidence that a VPAC strategy performed during symmetric lifting may potentially reduce exposure to biomechanical factors that can contribute to lumbar spine injury. The hamstring muscles may play an important role in achieving pelvic balance during the lifting maneuver. Incorporating the VPAC during dynamic stressful activities appears to help improve sensorimotor control and facilitate positioning of the lower extremities and the pelvis, while protecting the lumbar spine.
