For evaluating the lumbar stabilizing function, we reviewed the reproducibility of the test-retest examinations using a mercury sphygmomanometer, because of the non-invasive nature of this testing instrument. Fifty subjects (40 females, 10 males) who had no history of low back pain and leg pain were evaluated. The results of test-retest examinations, revealed a high correlation in both male and female subjects with regard to the difference of maximum and minimum pressure showed by mercury sphygmomanometer. This suggests that the assessment of the lumbar stabilizing function using a mercury sphygmomanometer is reproducible, and its practicality may be high even for evaluating in low back pain patients.
