Comparative Study Clinical TrialPatient characteristics, practice activities, and one-month outcomes for chronic, recurrent low-back pain treated by chiropractors and family medicine physicians: a practice-based feasibility study.
Chronic low-back pain is a significant public health problem for which few therapies are supported by predictable outcomes. In this report, practice activities and 1-month outcomes data are presented for 93 chiropractic patients and 45 medical patients with chronic, recurrent low-back pain. ⋯ Patients with chronic low-back pain treated by chiropractors show greater improvement and satisfaction at 1 month than patients treated by family physicians. Nonclinical factors may play an important role in patient progress. Findings from the Health Resources and Services Administration-funded project will include a report on the influence of practice activities, including more frequent visits by chiropractic patients, on the clinical course of low-back pain and patient outcomes.

A correlative design using stepwise regression analysis. ⋯ The results of this study strongly support the hypothesis that spinal physical capacity in chronicity is not explained solely by the sensory perception of pain. The anticipation of pain and the fear-avoidance belief about physical activities were the strongest predictors of the variation in physical performance.

Spinal troubles in sewage workers: epidemiological data and work disability due to low back pain.
To determine the prevalence of spinal troubles (i.e., neck, upper back and low back pain) in a population of sewage workers, and to establish the effect of sociodemographic, work-related, physical, and psychosocial factors on the reported work disability due to low back pain (LBP) during the previous 12 months. ⋯ This study revealed a high incidence of spinal troubles among sewage workers. In a multidisciplinary approach, we demonstrated that not one factor alone but a combination of sociodemographic, work-related and psychosocial factors have shown associations with work disabilities due to LBP. Additional studies evaluating the relative importance of individual risk factors are warranted.

This is a prospective test-retest repeatability study. ⋯ As reported by others, the intraevaluator repeatability was high. The results of this study, finding acceptable repeatability for most scoring methods for pain drawing completed on occasions separated by a relatively long period of time, support that the pain drawing is a stable instrument for use in chronic back pain patients.

The role of paraspinal muscle spindles in lumbosacral position sense in individuals with and without low back pain.
A two-group experimental design with repeated measures on one factor was used. ⋯ Patients with low back pain have a less refined position sense than healthy individuals, possibly because of an altered paraspinal muscle spindle afference and central processing of this sensory input. Furthermore, muscle vibration can be an interesting expedient for improving proprioception and enhancing local muscle control.
