Abstract

The purpose of this study were to detennine causes of low back pain in bus drivers whousually work in prolonged sitting position and to find the relationship of back pain withgeneral characteristics and work environmental characteristics, stress symptoms, to com-pre lordosis angle of habitual driving posture and resting posture in low back pain groupand non-low back pain group, and to use this result as a basis for improvement of workenvironment and comprehensive rehabilitative management of low back pain. Ninety-eightbus drivers were selected from the membership of an urban transit union in Seoul. These informations were collected from May 1, 1997 to May 25, 1997 by means of sσucturedquestionnaires and X -ray findings. These data were analyzed by x2 test, t-test, logisticregression using SAS. The major results were as follows:1. Of the respondents, 66.3% of bus drivers were found to be experiencing back pain. 2. Of the respondents of low back pain groups, 78.5% reported that major cause of lowback pain was due to prolonged sitting. 3. The group with experiences of frequent or continuous vibration had more low back pain(p < 0.05). There were no significant differences among other work environmental factors. 4. A verage stress score was significantly higher in the group with low back pain than inthe group without low back pain (p < 0.05). 5. The results of the logistic regression analyses were statistically significant，vibration fromseat and stress score among the risk factors (p < 0.05). 6. Averaged lordosis angle of habitual driving posture was 7.6± 14.9 degrees in low backpain group, 16.5 ±8.7 degrees in non-low back pain and averaged lordosis angle of restingsitting posture was 10.8±13.7 degrees in low back pain, 18.9± 9.6 degrees in nonlowback pain group but the difference in mean lordosis angles of two groups was notstatistically significant. The results of this study indicate that professional drivers developed chronicity of lowback pain due to unfit seat, poor habitual posture and stress from vibration or other riskfactors. Therefore, there is need to improve work environment, i.e. enough resting, to seta seat to support lumbar spine properly and to provide comprehensive rehabilitation programincluding early diagnosis, proper treatment and education for self help management.
