Table 4 -. Quantitative Sensory Testing (QST) Scores.
QST means and standard deviations (SD) were calculated by averaging the scores for the three trials completed on each body site. QST included mechanical detection thresholds (MDT), mechanical pain thresholds (MPT), and pressure pain thresholds (PPT). Means and SDs are reported by each time point (pre-and-post-surgery) for males, females, and the total sample. MDT and MPT values indicate the mean gram of the von Frey filament used. PPT values indicate the amount of pressure in Newtons reported by participants.
