Table 3 Median and range values for pain intensity ratings on visual analogue scale (VAS 0-10 cm), and total and referred pain drawing area sizes (mm2) after hypertonic saline infusion for the trapezius myalgia group (NSP) and for the controls (CON)

From: An increased response to experimental muscle pain is related to psychological status in women with chronic non-traumatic neck-shoulder pain

  NSP (n = 19) Median (range) CON (n = 30) Median (range) p-value
Mean VAS (cm) 4.0 (.4-7.9) 2.8 (.8-7.9) .002
Area under VAS curve (cm*s) 1616 (126-2842) 758 (50-2501) .001
Pain onset (s) 25 (0-115) 30 (10-285) .197
Peak VAS (cm) 7.6 (2.0-10.0) 5.0 (1.0-10.0) .006
Time to peak (s) 95 (50-350) 120 (35-655) .335
Total pain area size (mm2) 234 (36-3193) 113 (4-864) .013
Referred pain area size (mm2) 65 (0-1376) 0 (0-294) .020
  1. P-values for differences between groups were derived from Mann-Whitney U-tests.
