Table 4 Mean (standard deviation: SD) pressure pain thresholds (kPa) assessed over 14 locations (P1 to P14) covering the low back region, for left and right side (Pleft and Pright) as well as overall low back (Pall) and level of significance (p-values) among trial. See “Procedure to mark the 14 anatomical locations” for explanation concerning the locations of PPT assessments
