Abdominal Wall Evaluation in Low Back Pain

The purpose of this study was to evaluate feed-forward contraction of the transversus abdominis and thickness of the transversus abdominis, obliquus internus, and obliquus externus during calm and standardized respiration in low back pain patients and pain-free subjects.

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

For the low back pain group: women with history of non-specific chronic low back pain for more than three months
For the pain-free group: pain-free women

Exclusion criteria

For both groups were: pregnancy, neurological condition, obesity (body mass index: BMI >30), or previous spine or abdominal surgery.
For the low back pain group: rheumatology diseases other than low back pain.
For the pain-free group: any rheumatology disease.
