Objectives : The purpose of this study was to investigate abdominal muscles in chronic low back pain patients by meridian-electromyograph.
Methods : Sample group of 11 with from low back pain during three months and control group of 10 subjects without low back pain have been recruited. Outcomes were assessed using meridian-electromyograph, visual analogue scale, and oswestry disability index.
Results : Contraction power of external oblique abdominalis in control group was significantly higher than sample group, but there was no significant difference in muscle fatigue.
Conclusions : According to above results, there are correlations between abdominal muscles and low back pain.
