Use of Biofeedback Training to Correct Abnormal Neuromechanical Pattern in Chronic Low Back Pain Patients

Not Applicable

Completed

• Conditions: Mechanical Low Back Pain; Chronic Low Back Pain
• Interventions: Other: Biofeedback

• Registration Number: NCT02239289
• Lead Sponsor: Université du Québec à Trois-Rivières

Brief Summary

The purpose of the present study is to evaluate the benefit of biofeedback training on the capacity of chronic low back pain patients to decrease their lumbar paraspinal muscles activity during trunk full flexion and its relationship with changes in clinical outcomes. To do so, twenty patients with nonspecific mechanical low back pain will be recruited and all participants will take part in four sessions of supervised biofeedback training, consisting of 5 blocks with at least 12 trunk flexion-extension tasks. It is hypothesized that participants will have improved neuromechanical parameters with the biofeedback training and that this improvement will be positively associated to changes in clinical outcomes. This study will also allow for generation of preliminary data, in order to plan for a larger randomized control trial.

Arm && Interventions

Group	Intervention	Description
Biofeedback	Biofeedback	Subjects will be provided with four sessions of supervised biofeedback training

Primary Outcome Measures

Name	Time	Method
Flexion-relaxation Ratio	Week 4	Flexion-relaxation ratio is calculated by dividing muscle activity (EMG) during trunk flexion by muscle activity during full-flexed position. EMG of lumbar paraspinal muscles is recorder through surface EMG during every trials of each session.

Secondary Outcome Measures

Name	Time	Method
Lumbo-pelvic Range of Motion During Trunk Flexion-extension	Week 4	Range of motion is recorder throught 8 kinematic markers placed on the right lower limb and the back of each participant during every trials of each session.
Disability Level	Week 4	Oswestry disability index ranges from 0 to 100. A higher score indicates higher disability.
Pain Intensity in the Past Week	Week 4	101-points numerical rating scale that ranges from 0 (no pain) to 100 (worst possible pain).
Current Pain Intensity	Week 4	101-points numerical rating scale that ranges from 0 (no pain) to 100 (worst possible pain).
Fear of Movement Level	Week 4	Tampa scale for kinesiophobia ranges from 0 to 68. Higher score indicates higher fear of movement level.
