About this study

Official title: Correction of Abnormal Flexion-relaxation Phenomenon in Chronic Low Back Pain: the Benefit Associated With Biofeedback Training

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Flexion-relaxation Ratio

    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.

    Measured: Week 1

  2. Flexion-relaxation Ratio

    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.

    Measured: Week 2

  3. Flexion-relaxation Ratio

    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.

    Measured: Week 3

  4. Flexion-relaxation Ratio

    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.

    Measured: Week 4

Secondary outcomes (12)
  1. Lumbo-pelvic Range of Motion During Trunk Flexion-extension

    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.

    Measured: Week 1

  2. Disability Level

    Oswestry disability index ranges from 0 to 100. A higher score indicates higher disability.

    Measured: Week 4

  3. Pain Intensity in the Past Week

    101-points numerical rating scale that ranges from 0 (no pain) to 100 (worst possible pain).

    Measured: Week 2

  4. Current Pain Intensity

    101-points numerical rating scale that ranges from 0 (no pain) to 100 (worst possible pain).

    Measured: Week 3

  5. Fear of Movement Level

    Tampa scale for kinesiophobia ranges from 0 to 68. Higher score indicates higher fear of movement level.

    Measured: Week 4

  6. Current Pain Intensity

    101-points numerical rating scale that ranges from 0 (no pain) to 100 (worst possible pain).

    Measured: Week 2

  7. Current Pain Intensity

    101-points numerical rating scale that ranges from 0 (no pain) to 100 (worst possible pain).

    Measured: Week 4

  8. Pain Intensity in the Past Week

    101-points numerical rating scale that ranges from 0 (no pain) to 100 (worst possible pain).

    Measured: Week 3

  9. Pain Intensity in the Past Week

    101-points numerical rating scale that ranges from 0 (no pain) to 100 (worst possible pain).

    Measured: Week 4

  10. Lumbo-pelvic Range of Motion During Trunk Flexion-extension

    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.

    Measured: Week 2

  11. Lumbo-pelvic Range of Motion During Trunk Flexion-extension

    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.

    Measured: Week 3

  12. Lumbo-pelvic Range of Motion During Trunk Flexion-extension

    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.

    Measured: Week 4
