Oxygenation of Paravertebral Muscles During Exercise in Chronic Low Back Pain Patients (OXYLOM)

This study is currently recruiting participants. (see Contacts and Locations)

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.

Further study details as provided by University Hospital, Lille:

Primary Outcome Measures:
  • Deoxyhemoglobin [ Time Frame: 20 minutes ]
    Expressed in arbitrary unit, at rest and during the isokinetic exercises (2 exercises of 5 minutes)

Secondary Outcome Measures:
  • Oxygen consumption [ Time Frame: 20 minutes ]
    Measured in mL/min/kg, at rest and during the isokinetic exercises (2 exercises of 5 minutes)

  • Work rate [ Time Frame: 10 minutes ]
    Total work measured by the dynamometer in Joules during each exercises

  • Rate of perceived exertion [ Time Frame: 10 minutes ]
    Bases on the Borg's Scale, evaluating the perceived exertion on a scale from 6 to 20

  • Pain [ Time Frame: 10 minutes ]
    Bases on a visual analogic scale evaluating the pain on a scale from 0 to 10

  • Muscular blood volume [ Time Frame: 20 minutes ]
    Expressed in arbitrary unit, at rest and during the isokinetic exercises (2 exercises of 5 minutes)
