An interventional study of Dry needling and Sham needling in Back Pain, sponsored by University of Nevada, Las Vegas. Completed at 1 site in United States. Open to participants aged 18 Years to 60 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2013-06-19.

Intramuscular therapy (also known as dry needling) has been shown to give dramatic relief of musculoskeletal pain. The mechanisms of action remain unknown, and this study will examine for a neurophysiological effect.
Consenting adults will be taught how to contract their abdominal muscles, and to contract transversus abdominis in particular. They will then have real time ultrasound measurements of the resting and contracted thickness of their left transversus abdominis muscle. After this, they will receive actual or sham needling to their left multifidus muscle by another researchers blinded to the real time ultrasound measurements. After needling or sham intervention is complete, the original researchers will return to re-measure transversus abdominis. They will be blind to intervention allocation.

Exclusion Criteria:
Monofilament needles will be inserted into each subject's left multifidus muscle and stimulated mechanically for a local twitch response
Procedure: Dry needling
Monofilament tubes will be pressed into the left multifidus muscle and mechanically manipulated to give the sensation that needling is occuring.
Procedure: Sham needling
Sterile monofilament needles
Applicator tubes from the sterile monofilament needles
Thickness of transversus abdominis at rest and during contraction
Real time ultrasound measurement
Time frame: 1 day
