Assessment of Pain Perception and the Impact of Central Sensitization on Biopsychosocial Manifestations During Physical Activity in Patients With Chronic Low Back Pain
Sponsor: University Hospital, Brest
Summary
The goal of this prospective observational study is to evaluate changes in cognitive and behavioural markers associated with central sensitisation between the start and end of an exercise retraining programme on an exercise bike, in adult patients suffering from chronic lower back pain associated with an untreated degenerative spine, worth or without referred pain. The main changes it will evaluate are: \- Changes in cognitive and behavioural markers associated with central sensitisation between Day 0 and Day 40 during exercise retraining on an exercise bike as part of a rehabilitation programme for chronic low back pain Participants will undergo the followings: * A calibration test used to define moderate exertion on an ergocycle, corresponding to a perceived exertion of 4-5/10 on the modified Borg scale * Exercise-induced pain intensity assessment tests to detect changes in the intensity of pain during physical activity and the activity's potential to cause pain, realised on ergocyle * Exercise rehabilitation on an ergocycle * Final tests to assess cognitive and behavioural markers related to central sensitisation and pain intensity, as at baseline.

Exercise rehabilitation on an ergocycle
Following enrolment, patients will undergo a calibration test on an ergocycle on Day 1 to determine the power required to maintain a constant moderate effort corresponding to an intensity of 4-5/10 on the modified Borg scale. Then, to assess the pain-inducing potential of exercise on the ergocycle, they will undertake two tests (on Day 3 and Day 5) to evaluate changes in pain during constant moderate exertion. During their rehabilitation programme for low back pain, patients will undergo exercise retraining on the ergocycle. From Day 8 to Day 40 (three times a week, on Mondays, Wednesdays and Fridays), the patients' perception of exertion will be assessed at the end of each exercise bike session to ensure that they are maintaining a constant moderate level of exertion. Patients will be assessed on Day 40 to collect data on cognitive and behavioural markers related to central sensitisation and pain intensity, as at baseline.
