A prospective study of psychological risk factors for first-time low back pain with repeated use of psychological questionnaires. ⋯ The scores from the Modified Somatic Perception Questionnaire and Zung questionnaire were reproducible over 18 months and were affected little by first episodes of back pain; yet these scores were significant predictors of it. "Abnormal" scores from these questionnaires precede back pain in a small number of people.

The contribution of transversus abdominis to spinal stabilization was evaluated indirectly in people with and without low back pain using an experimental model identifying the coordination of trunk muscles in response to a disturbances to the spine produced by arm movement. ⋯ The delayed onset of contraction of transversus abdominis indicates a deficit of motor control and is hypothesized to result in inefficient muscular stabilization of the spine.

A survey of occupational risks for low back trouble in two police forces discordant for one known physical stressor (wearing body armor weighing approximately 8.5 kg. ⋯ Exposure to occupational physical stress seems detrimental; It reduced survival time to first-onset of low back trouble. Recurrence was associated with time since onset, but persistent trouble was not. Sports participation was a risk if occupational hazards were high.

Randomized Controlled Trial Comparative Study Clinical TrialTrunk exercise combined with spinal manipulative or NSAID therapy for chronic low back pain: a randomized, observer-blinded clinical trial.
To study the relative efficacy of three different treatment for chronic low back pain (CLBP). Two preplanned comparisons were made: (a) Spinal manipulative therapy (SMT) combined with trunk strengthening exercises (TSE) vs. SMT combined with trunk stretching exercises, and (b) SMT combined with TSE vs. nonsteroidal anti-inflammatory drug (NSAID) therapy combined with TSE. ⋯ Each of the three therapeutic regimens was associated with similar and clinically important improvement over time that was considered superior to the expected natural history of long-standing CLBP. For the management of CLBP, trunk exercise in combination with SMT or NSAID therapy seemed to be beneficial and worthwhile. The magnitude of nonspecific therapeutic (placebo) effects, cost-effectiveness and relative risks of side effects associated with these types of therapy need to be addressed in future studies.
