458 CLINICAL FINDINGS AS PREDICTORS OF LOW BACK PAIN AMONG A NORMAL WORKING POPULATION SAMPLE WITH LONG FOLLOW‐UP PERIODS

Pain and clinical findings in the low back: a study of industrial employees with 5-, 10-, and 28-year follow-ups.

Little is known about the relationships of clinical findings in the low back with low back pain (LBP) in the normal working population. We studied whether physiotherapist's findings in the low back were associated with local and radiating LBP among a cohort (n=902) of employees in the engineering industry. A systematic non-proportional sample was drawn in strata by age, gender, and occupational class. The non-proportionality aimed at increasing sample size in smaller strata. Physiotherapists performed the straight-leg raising test (SRL), and made assessments of the fingertip-to-floor distance and pain in palpation of the lumbar interspinous spaces. The variables on pain at the interspinous …

Low back pain, work absenteeism, chronic back disorders, and clinical findings in the low back as predictors of hospitalization due to low back disorders: a 28-year follow-up of industrial employees.

Study Design. Prospective cohort study. Objective. To study symptoms, chronic disorders, and clinical findings in the low back, and work absenteeism, as predictors of hospitalization. Summary of Background Data. Socioeconomic and lifestyle factors are associated with back-related hospitalization, but the significance in the working normal population of low back symptoms and clinical findings are not known. Methods. The cohort (n = 902) was drawn in 1973 from among employees in the metal industry (n = 2,653). The data were collected by questionnaire and a structured clinical assessment by a physiotherapist. Weight was measured. A sum score of local and radiating low back symptoms (frequency …

Cognitive behavioral therapy for chronic insomnia inoccupationalhealth services: Analyses of outcomes upto24monthspost-treatment

Abstract Objective Cognitive behavioral therapy for insomnia (CBT-I) is an effective treatment for persistent insomnia. The purpose of this study was to examine the effectiveness of and response patterns to CBT-I among daytime and shift workers with insomnia over a 24-month follow-up in occupational health services (OHS). Methods The participants were 59 media workers with chronic insomnia, of whom 69% were reached at 24-month follow-up. Sleep diaries and questionnaires over seven measurement points were used as outcomes. Trained OHS nurses led the CBT-I groups. The study design was a non-randomized group intervention. Results Self-perceived severity of insomnia, sleep-related dysfunctional…

Persistence of low back pain reporting among a cohort of employees in a metal corporation: A study with 5-, 10-, and 28-year follow-ups

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. At baseline, 54% of the subjects reported local LBP and 25% LBP radiating to the lower limb(s). Persistent or recurrent LBP was common. Of those with LBP at baseline, 75, 73, and 88% reported it also at the 5-, 10- or 28-year follow-up, respectively. Of those with radiating pain, 66, 65, an…
