Facial Expression Overrides Lumbopelvic Kinematics for Clinical Judgements about Low Back Pain Intensity
Figure 1
(a, b) Examples of trunk flexion frames taken from a video: (a) illustrates the prototypical low back pain lumbopelvic kinematics (“LBP LK”), whereas (b) represents the prototypical healthy lumbopelvic kinematics (“healthy LK”). (c–f) Examples of facial expression intensity (FEI): (c) corresponds to the masked FEI (“masked FEI”), (d) to “FEI 0%,” (e) to “FEI 50%,” and (f) to “FEI 100%.”
