Text: The sums of differences between postmedication and premedication values of pain measures differed between the placebo/tramadol and the placebo/placebo combination, with median values as follows : pressure pain tolerance threshold, 390 kPa (95 % confidence interval [CI], 211 to 637 kPa) versus -84 kPa (95 % CI, - 492 to -32 kPa) (P =. 001) ; single sural nerve stimulation pain tolerance threshold, 25. 8 mA (95 % CI, 15. 3 to 29. 8 mA) versus 9. 0 mA (95 % CI, 1. 5 to 14. 8 mA) (P =. 005) ; pain summation threshold, 10. 7 mA (95 % CI, 5. 2 to 17. 6 mA) versus 5. 0 mA (95 % CI, 2. 8 to 11. 2 mA) (P =. 066) ; cold pressor pain, -4. 2 cm x s (95 % CI, -6. 8 to -1. 9 cm x s) versus -0. 4 cm x s (-1. 4 to 1. 4 cm x s) (P =. 002) ; and discomfort, -4. 7 cm (95 % CI, -10. 6 to -2. 8 cm) versus 0. 5 cm (-0. 1 to 1. 4 cm) (P =. 002).
