Low Back Pain, Muscular Weakness, Rehabilitation Program

Keywords
Isokinetic, oxygenation, deoxygenation, aerobic metabolism
Brief summary
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.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Deoxyhemoglobin | 20 minutes | Expressed in arbitrary unit, at rest and during the isokinetic exercises (2 exercises of 5 minutes) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Work rate | 10 minutes | Total work measured by the dynamometer in Joules during each exercises |
| Rate of perceived exertion | 10 minutes | Bases on the Borg's Scale, evaluating the perceived exertion on a scale from 6 to 20 |
| Oxygen consumption | 20 minutes | Measured in mL/min/kg, at rest and during the isokinetic exercises (2 exercises of 5 minutes) |
| Muscular blood volume | 20 minutes | Expressed in arbitrary unit, at rest and during the isokinetic exercises (2 exercises of 5 minutes) |
| Sorensen test | 20 minutes | 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. |
| Pain | 10 minutes | Bases on a visual analogic scale evaluating the pain on a scale from 0 to 10 |
