Manipulation Effects on Abdominal Muscles
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.
|Study Design:||Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator, Outcomes Assessor)
Primary Purpose: Basic Science
|Official Title:||The Immmediate Effects of Thrust Joint Manipulation on the Resting and Contraction Thickness of Transversus Abdominis in Subjects With Low Back Pain|
- Transversus abdominis thickness change [ Time Frame: Baseline to immediately after the intervention (within 5 minutes) ] [ Designated as safety issue: No ]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.
- Numeric Pain Rating Scale [ Time Frame: Baseline to immediately after the intervention (within 5 minutes) ] [ Designated as safety issue: No ]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.

|Estimated Primary Completion Date:||August 2013 (Final data collection date for primary outcome measure)|
Active Comparator: Lumbar manipulation
Patients will receive thrust joint manipulation to their lumbar spine in side lying
Other: Lumbar Manipulation
Manual therapy intervention
Sham Comparator: Sham manipulation
Patients will receive oscillations into slight rotation, without cavitation, in side lying
Other: Sham manipulation
Manual therapy intervention
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.
