Study Overview
Brief Summary
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.
Detailed Description
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.

Inclusion Criteria
- •Currently receiving physical therapy treatment for back pain or back pain symptoms
- •18-70 years of age
- •Able to perform the abdominal drawing in maneuver
Exclusion Criteria
- •Presence of a serious pathology
- •Diagnosis of spinal stenosis or symptoms in both lower legs (changes in sensation, muscle weakness)

Outcomes
Primary Outcomes
Transversus abdominis thickness change
Time Frame: Baseline to immediately after the intervention (within 5 minutes)
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.
Secondary Outcomes
- Numeric Pain Rating Scale(Baseline to immediately after the intervention (within 5 minutes))
