Correlates of the tourniquet ischemia pain ratio.

The Tourniquet Ischemia Pain Ratio was developed as a measure of pain. The present study examined the relationship between the ratio and other measures thought to be relevant to a patient's perception of, and reaction to, chronic pain. The ratio was correlated with the patient's estimate of the pain, the perceived impact of the pain on daily life, the degree of reactive depression, and a measure of hypochondriasis. The ratio relates to both pain and hypochondriacal tendencies.
