Ultrasound Assessment During Exercise (Redcord RUSI)

This study has been completed.
Information provided by:
University of Virginia Identifier:
First received: September 28, 2009
Last updated: November 16, 2009
Last verified: November 2009
This study evaluates the ability of the transverse abdominis (TrA) to contract during and after two different types of exercise - either sling based exercise or traditional core stability exercise. The TrA is measured by real time ultrasound imaging. The investigators hypothesized that the sling based exercise would activate the TrA to a greater degree and that there would be a greater activation after the exercise.

Condition Intervention
Low Back Pain Other: Exercise Other: Core stability exercise

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Outcomes Assessor)
