The study evaluate paraspinal aerobic metabolism of chronic low back pain patients and healthy people during an original and standardized isokinetic protocol. The aim of this study is to determine a potential alteration of muscular aerobic metabolism in low back pain patients, in order to establish the underlying cause of pain and muscular fatigability characterizing low back pain patients. Then, the aim is to determine if functional rehabilitation program can improve it. the unit of care have access to metabolic adaptations in measuring the muscular oxygenation and the pulmonary oxygen consumption, using near infrared spectroscopy and gas analyser.

Oxygen consumption
Measured in mL/min/kg, at rest and during the isokinetic exercises (2 exercises of 5 minutes)
Time frame: 20 minutes
Work rate
Total work measured by the dynamometer in Joules during each exercises
Time frame: 10 minutes
Rate of perceived exertion
Bases on the Borg's Scale, evaluating the perceived exertion on a scale from 6 to 20
Time frame: 10 minutes
Pain
Bases on a visual analogic scale evaluating the pain on a scale from 0 to 10
Time frame: 10 minutes
Muscular blood volume
Expressed in arbitrary unit, at rest and during the isokinetic exercises (2 exercises of 5 minutes)
Time frame: 20 minutes
Sorensen test
test is a timed measure used to assess the endurance of the trunk extensor muscles. It is used to assist in the prediction of the incidence and occurrence of low back pain in patients.
Time frame: 20 minutes
