Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with low back pain will undergo ultrasound imaging of the lateral abdominal wall to measure resting and contracted thickness of the transversus abdominis muscle. Following the pre-intervention measurement, patients will receive one of two physical therapy interventions (side lying thrust joint manipulation or side lying non-thrust oscillations into slight rotation) which will have been randomly assigned. Immediately after intervention, ultrasound imaging will be repeated on the resting and contracted thickness of the transversus abdominis.
