Randomized Controlled Trial
Is activation of transversus abdominis and obliquus internus abdominis associated with long-term changes in chronic low back pain? A prospective study with 1-year follow-up.
To investigate associations between deep abdominal muscle activation and long-term pain outcome in chronic non-specific low back pain (LBP). ⋯ Improved transversus abdominis lateral slide among participants with low baseline slide was associated with clinically important long-term pain reduction. High baseline slide and delayed onset of abdominal muscles after the intervention period were weakly associated with higher pain at 1-year follow-up. Clinical Trial Registration number The study was preregistered in ClinicalTrials.gov with identifier NCT00201513.
