Effects of the centrifugal contraction exercise of the rectus abdominis accompanied with the isometric exercise of the transversus abdominis on pain and balance of lower back pain patients.

[Purpose] The current study attempted to examine the effects of centrifugal contraction exercise of the rectus abdominis during the isometric contraction of the transversus abdominis on pain and balance of patients with chronic back pain. [Subjects and Methods] The subjects included thirty patients who were diagnosed with back pain due to causes other than neurological by a specialist after conducting a medical precision diagnosis. The experiment was performed after evenly dividing the subjects into two groups, namely, control and experimental, using a random method. This study measured pain by using the visual analog scale. To determine the patients' balancing ability using the Multifunktionale trainsgerate balance measurer. [Results] All groups showed a statistically significant within-group difference in visual analog scale and balance change. However, no significant between-group difference was observed in the comparison of therapy effects. [Conclusion] Strengthening the rectus abdominis can be an important factor for increasing the stability and reducing the pain of the lumbar area among patients with back pain.
