Effect of Two Osteopathic Techniques on Thickness of Paravertebral Muscles of the Lumbar Spine

Not Applicable

• Conditions: Low Back Pain
• Interventions: Other: Muscle energy (ME); Other: Sham; Other: High-velocity, low-amplitude (HVLA)

• Registration Number: NCT01971983
• Lead Sponsor: Federal University of Health Science of Porto Alegre

Brief Summary

The objective of this randomized controlled trial is to describe the effect of two osteopathic techniques - "high velocity, low amplitude" (HVLA) and muscle energy (ME) - on thickness, activation, strength, pressure pain threshold (PPT) of the paravertebral muscles at the lumbar spine, as well as the peak plantar pressures immediately and after a two-day follow-up.

The muscle thickness of the paravertebral muscles at the lumbar spine, namely internal oblique, external oblique and transversus abdominis can be altered after the application of 'high-velocity low-amplitude'(HVLA)and 'muscle energy' (ME)techniques immediately and after a two-day follow-up.

Arm && Interventions

Group	Intervention	Description
ME	Muscle energy (ME)	Subjects allocated to this group will receive a muscle energy (ME) technique.
Sham group	Sham	The individuals allocated to this group received an intervention of the "sham". The sample of this group will consist of subjects with history of dysfunctions of the lumbar spine.
HVLA	High-velocity, low-amplitude (HVLA)	The subjects allocated to this group will receive a 'High-velocity, low-amplitude (HVLA) technique over the lumbar spine.

Primary Outcome Measures

Name	Time	Method
Muscle thickness	Two days	We will evaluate the muscle thickness of four muscles that comprises the paravertebral musculature at the lumbar spine: internal oblique, external oblique, lumbar multifidus and transversus abdominis.

Secondary Outcome Measures

Name	Time	Method
Pressure pain threshold	Two days	subjects will be evaluated regarding their pressure pain threshold (PPT) on the spinous process of all of the lumbar vertebrae.
