No results posted yet for this study

Summary

The main objective of this study is to compare on day 0 the maximum Lyapunov exponent (lmax, an indicator of local dynamic stability) of chronic low back pain patients versus that of healthy volunteers matched for age (± 5 years), sex and body mass index (BMI ± 15% of low back pain patients).

Conditions

  • Low Back Pain
  • Chronic Low Back Pain

Interventions

OTHER

Flexion-extension in the sagittal plane

The movement required is a flexion - extension where the subject touches a target (adapted to his/her morphology) with both index fingers: the target is positioned in front of the subject, inline with his/her outstretched arms and at knee height. This movement simulates a lifting task without weight. The movement is repeated 30 times with a return to the initial position at a frequency of 0.32Hz.

OTHER

Rotation in a transverse plane

The movement required of the subject is a rotational movement where the subject alternately touches with his/her left and right hands two targets. The latter are positioned horizontally on either side of the subject at shoulder height and at arm's length. The movement is repeated 30 times at a frequency of 0.28 Hz.

OTHER

Complex movement in three dimensions

The subject is required to successively touch 4 targets situated (i) at knee height to the left of the subject, (ii) at shoulder height to the right of the subject, (iii) at shoulder height to the left of the patient, and (iv) at knee height to the right of the patient. The movement is repeated 30 times at a frequency of 0.16 Hz.
