Study Start Date: December 2009
Study Completion Date: November 2010
Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts
Nineteen women with low back pain
Twenty pain-free women

Detailed Description:
Low back pain patients have alterations in abdominal wall function, especially in the feed-forward activation of transversus muscle during limbs movements. However, there are no reports on the abdominal function in low back pain patients during physiological respiratory movement.
