A randomized controlled trial comparing McKenzie therapy and motor control exercises on the recruitment of trunk muscles in people with chronic low back pain: a trial protocol

Abstract

Objective

To investigate if McKenzie exercises when applied to a cohort of patients with chronic LBP who have a directional preference demonstrate improved recruitment of the transversus abdominis compared to motor control exercises when measurements were assessed from ultrasound images.

Design

A randomized blinded trial with a 12-month follow-up.

Setting

The Physiotherapy department of Concord Hospital a primary health care environment.

Participants

70-adults with greater than three-month history of LBP who have a directional preference.

Interventions

McKenzie techniques or motor control exercises for 12-sessions over eight weeks.

Main outcome measures

Transversus abdominus thickness measured from real time ultrasound images, pain, global perceived effect and capacity to self-manage.

Discussion

This study will be the first to investigate the possible mechanism of action that McKenzie therapy and motor control exercises have on the recruitment of the transversus abdominus in a cohort of low back pain patients sub-classified with a directional preference. Patients receiving matched exercises according to their directional preference are believed to have better outcomes than those receiving unmatched exercises. A better understanding of the mechanism of action that specific treatments such as motor control exercises or McKenzie exercises have on patients classified with a directional preference will allow therapist to make a more informed choice about treatment options.
