Abstract
We studied the relationship between respiratory function and trunk muscle strength in patients with low back pain [Subject and Method]: At first we examined a correlation between the trunk muscle strength and respiratory function in healthy young women. Next step was that we compared the respiratory function between the patients with the low back pain and osteoarthritis of lower extremities. [Result]: No relationship between muscle strength and respiratory function was found in healthy women. The low back pain group, however, was highly significant in VC and FVC and ERV. [Conclusion]: We think that there is a little influence of rectus abdominis on the respiratory function. On the contrast, the abdominal transverse muscle could play a significant role to the abdominal transverse muscle is very important in patients with low back pain. So we suggest that ERV is to be increased by using the abdominal transverse muscle.
