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

NCT ID: NCT01971983

Last Updated: 2014-03-18

Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: NA
• Total Enrollment: 60 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2013-02-28
• Study Completion Date: 2014-12-31

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.

Conditions

Low Back Pain

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

HVLA

The subjects allocated to this group will receive a 'High-velocity, low-amplitude (HVLA) technique over the lumbar spine.

Group Type: EXPERIMENTAL

High-velocity, low-amplitude (HVLA)

Intervention Type: OTHER

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.

ME

Subjects allocated to this group will receive a muscle energy (ME) technique.

Group Type: EXPERIMENTAL

Muscle energy (ME)

Intervention Type: OTHER

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 group

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.

Group Type: SHAM_COMPARATOR

Sham

Intervention Type: OTHER

Individuals in this group received a sham intervention type, in order to simulate an intervention.
