説明

The authors have already discussed low back pain among workers in small scale construction companies in Report 1, in which we demonstrated the high prevalence of low back pain among the workers.<BR>The clinical and radiological examination did not always correlate with clinical findings.<BR>We concluded, therefore, that radiological examination is not so helpful in mass screening for low back pain.<BR>In order to develop more accurate screening procedures, various kinds of clinical findings were discussed.<BR>The results are as follows.<BR>1) The workers with frequent complaints of low back pain have a higher incidence of other musculo-skeletal symptoms than those who experience occasional or no low back pain.<BR>Duration of continuing low back pain among the former is longer than among those in the latter group.<BR>2) A close relationship between the severity of low back pain and the following clinical findings exists.<BR>a) point tenderness of the paravertebral muscles b) pain produced upon flexion, extension or abduction of the trunk c) limitation of flexion-extension of the trunk d) punch tenderness of the vertebral e) disappearance of lordosis f) hypesthesia of the lower extremities<BR>3) Bilateral pateller and / or Ackilles tendon reflexes were different in workers with low back pain.<BR>4) Weakness on extension and flexion of the big toe was often found among the workers with severe low back pain.<BR>5) The authors demonstrated that low back pain is related to strengh of back muscles.<BR>The findings described above indicate that the workers have many difficulties complying with the new recommendations for preventing low back pain.
