Brief Summary

The goal of this observational study is to compare the postural response to the mental simulation of everyday situations identified as painful in participants with non-specific low back pain and healthy volunteers. The main questions it aims to answer are : Do participants with low-back pain show reduced variability in center of pressure displacements compared with non-painful participants when faced with mental simulation of everyday situations identified as painful? Is the postural response correlated with the level of kinesiophobia? Participants will be faced to pictures of everyday situations identified as painful while several physiological measurements (posturography, electromyography, heart rate) are being recorded.

Conditions

Non-specific Chronic Low Back Pain; Healthy Volunteer

Keywords

Kinesiophobia; Low back pain; Posturography

Outcome Measures

Primary Outcomes (1)

• Standard deviation of the position of the center of pressure on the anteroposterior axis (SD-COP-AP)

  Movements of the center of pressure (COP) are recorded using a force plate, and the SD-COP-AP is calculated after recording and is an indicator of the postural response.

  Baseline

Secondary Outcomes (26)

• Mean position of the center of pressure on the anteroposterior axis (COP-AP)

  Baseline

• Mean position of the center of pressure on the mediolateral axis (COP-ML)

  Baseline

• Standard deviation of the position of the center of pressure on the mediolateral axis (SD-COP-ML)

  Baseline

• Sway length of the center of pressure on the anteroposterior axis (L-COP-AP)

  Baseline

• Sway length of the center of pressure on the mediolateral axis (L-COP-ML)

  Baseline

Study Arms (2)
