Condition low back pain
Treatments high-velocity, low-amplitude (hvla), muscle energy (me), sham
Sponsor Federal University of Health Science of Porto Alegre
Start date February 2013
End date June 2014
Trial size 60 participants
Trial identifier NCT01971983, Osteo-ufcspa


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.

Study Design

Allocation randomized
Endpoint classification efficacy study
Intervention model parallel assignment
Masking single blind (outcomes assessor)
Primary purpose treatment
The subjects allocated to this group will receive a 'High-velocity, low-amplitude (HVLA) technique over the lumbar spine.
high-velocity, low-amplitude (hvla) Thrust manipulation
With the subject lying on his/her side, the therapist will rotate the patient's trunk, flex his/her hip and knee of the upper leg. The therapist positions his caudad forearm over the hip, while the cephalad forearm lies over the patient's shoulder. The therapist's hands will be positioned over the lumbar spine's spinous process to be manipulated.
Subjects allocated to this group will receive a muscle energy (ME) technique.
muscle energy (me) Mitchell's technique
This technique involves the active movement of the patient to activate a specific musculature in order to move a bony segment of a given joint in a specific direction in relation to the adjacent bone. This technique aims to restore the restricted movement of the joint in question.
(Sham Comparator)
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.
Individuals in this group received a sham intervention type, in order to simulate an intervention.
