Table 2 Temporal summation (TS) and conditioned pain modulation (CPM) effects

From: Temporal summation of mechanical pain prospectively predicts movement-evoked pain severity in adults with chronic low back pain

  Mean (SD) Sig.
TS of mechanical pain (512mn) at the low back
 1 Contact 32.6 (31.7)  
 10 Contacts 50.1 (33.7) t = 10.54, p < .001
CPM at the low back
 Baseline PPT 411.6 (213.2)  
 Conditioned PPT 430.6 (221.4) t = 1.94, p = .054
  1. Note: 1 Contact = pain intensity rating (0–100) in response to first contact with mechanical stimuli, 10 contact = pain intensity rating (0–100) in response to 10 contacts with mechanical stimuli; PPT pressure pain threshold measured in kilopascals (kPa)
