The purpose of this study is to understand how different physical therapy interventions affect the use of certain abdominal muscles in patients with low back pain.
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.

Transversus abdominis thickness change
Measurement of change in thickness from resting to contraction will be compared at baseline (pre-intervention) to immediately following the intervention (post-intervention). The study is looking at the immediate effects so there is no short-term or longer term follow up.
Time frame: Baseline to immediately after the intervention (within 5 minutes)
Numeric Pain Rating Scale
Rating of perceived pain will be compared at baseline (pre-intervention) to immediately following the intervention (post-intervention). The study is looking at the immediate effects so there is no short-term or longer term follow up.
Time frame: Baseline to immediately after the intervention (within 5 minutes)
