Facial Expression Overrides Lumbopelvic Kinematics for Clinical Judgements about Low Back Pain Intensity

Figure 5

Illustrations of individual differences in participants who integrated both lumbopelvic kinematics (LK) and facial expression intensity (FEI). The functional data of participants’ responses is expressed as a function of their subjective scaling Ψhealthy LK and ΨLBP LK, corresponding to each physical stimulus value to Φhealthy LK and ΦLBP LK.
