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.

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.
Time frame: Week 1

Time frame: Week 4
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.
Time frame: Week 1
Disability Level
Oswestry disability index ranges from 0 to 100. A higher score indicates higher disability.
Time frame: Week 4
Pain Intensity in the Past Week
101-points numerical rating scale that ranges from 0 (no pain) to 100 (worst possible pain).
Time frame: Week 2
Current Pain Intensity
101-points numerical rating scale that ranges from 0 (no pain) to 100 (worst possible pain).
Time frame: Week 3
Fear of Movement Level
Tampa scale for kinesiophobia ranges from 0 to 68. Higher score indicates higher fear of movement level.
Time frame: Week 4
Current Pain Intensity
101-points numerical rating scale that ranges from 0 (no pain) to 100 (worst possible pain).
Time frame: Week 2
