简要总结
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.

结局指标
主要结局
Standard deviation of the position of the center of pressure on the anteroposterior axis (SD-COP-AP)
时间窗: Baseline
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.
