Assessment of pain in patients with whiplash-associated disorders has been previously reported using a variety of instruments. However, the reproducibility of the findings derived from such measurements has not been explored with respect to this particular patients group. ⋯ On the basis of the current patient sample, this study demonstrates that although PPT findings may generally be applied for monitoring change in chronic whiplash patients, the use of VAS scores should be limited to patients whose initial score is above 4. It is also suggested that if the PPT is to serve as an outcome measure, its measurement should be performed by the same tester.
