Correction: The Area of Secondary Hyperalgesia following Heat Stimulation in Healthy Male Volunteers: Inter- and Intra-Individual Variance and Reproducibility

Abstract

There is an error in the second sentence under the sub-heading "Assessment of secondary hyperalgesia." within the "Pain models" section of the "Material and Methods". The correct sentence is: The area was quantified by stimulation with a monofilament (Von Frey hair) with a nominal value of 18 (bending force of 490 mN) in 4 linear paths arranged 90˚around the center of the heat-stimulation.
