Prevalence and individual risk factors associated with clinical lumbar instability in minibus drivers with low back pain
Low back pain (LBP) is the most common musculoskeletal disorder in bus drivers. Lumbar instability is one of the causes of LBP. Therefore, the current study aimed to investigate the prevalence and risk factors associated with CLI in minibus drivers with LBP. This study design was a cross-sectional survey on 236 minibus drivers, conducted in Sakon Nakhon province, Thailand. The 14 physical examinations for lumbar instability containing sit to stand test, aberrant movement pattern test, Beighton's hypermobility scale, lumbar flexion test, total trunk extension, interspinous gap change test, posterior shear test, prone instability test, painful catch sign test, passive accessory intervertebral motions test, passive physiological intervertebral motions in trunk flexion test, passive physiological intervertebral motions in trunk extension test, passive lumbar extension test, and average SLR test, were performed. The method has used a questionnaire to answer of the risk factors associated. The prevalence of CLI in minibus drivers found in this study was 75.42% (age 54±11 years). The result of this study shows a significant of the drivers who had an exercise (p=0.034, p-value < 0.05).
