Although obesity and physical activity have been argued to predict back pain, these factors are also related to incontinence and breathing difficulties. Breathing and continence mechanisms may interfere with the physiology of spinal control, and may provide a link to back pain. The aim of this study was to establish the association between back pain and disorders of continence and respiration in women. ⋯ Similarly, mid-aged and older women had higher odds of having back pain often when they experienced breathing difficulties often compared to women with no breathing problems (OR of 2.0 and 1.9, respectively). Unlike obesity and physical activity, disorders of continence and respiration were strongly related to frequent back pain. This relationship may be explained by physiological limitations of co-ordination of postural, respiratory and continence functions of trunk muscles.

Low back pain (LBP) is a common symptom among adults but little is known about its persistence over time in defined populations. The aim of this study was to examine the persistence of LBP among a cohort of industrial employees studied in four successive surveys during a total of 28 years. Cross-tabulations and logistic regression was used to estimate the interdependence of LBP occurrence at the surveys. ⋯ The odds ratio of local LBP at the 5-, 10-, or 28-year follow-up for those with such pain at baseline vs. not were 6.0 (95% CI 4.3-8.3), 4.7 (3.3-6.6) and 4.0 (2.6-6.3), adjusted for age, gender and occupational class. The respective figures for radiating LBP were 8.5 (5.7-12.5), 6.7 (4.4-10.1) and 2.3 (1.5-3.6). We conclude that LBP is commonly recurrent.

Prospective case series with historical controls (normative data). ⋯ CLBP patients, especially men, seem to have a reduced aerobic fitness level compared with the normative population. No explanatory factor for that loss could be identified.

A literature review of the most widely used condition specific, self administered assessment questionnaires for low back pain had been undertaken. General and historic aspects, reliability, responsiveness and minimum clinically important difference, external validity, floor and ceiling effects, and available languages were analysed. ⋯ Of similar importance are the content, wording of questions and answers in each of the six questionnaires and an analysis of the different score results. The issue of score bias is discussed and suggestions are given in order to increase the construct validity in the practical use of the individual questionnaires.

Randomized Controlled Trial Comparative Study
Infrared therapy for chronic low back pain: a randomized, controlled trial.
The objective of the present study was to assess the degree of pain relief obtained by applying infrared (IR) energy to the low back in patients with chronic, intractable low back pain. ⋯ The IR therapy unit used was demonstrated to be effective in reducing chronic low back pain, and no adverse effects were observed.
