Comparative Study
A psychophysical analysis of experimential factors that selectively influence the affective dimension of pain.
A psychophysical analysis was made of experiential factors that influence the affective but not the sensory-discriminative dimension of pain. Seven subjects made cross-modality matching responses to several dimensions of their experience. Before each stimulus, they matched line lengths to their experienced desire to avoid pain (significance) and to their perceived likelihood of avoiding it (expectation). ⋯ In the other session, they simply focused on the pleasantness or unpleasantness of each sensation as it was experienced (affect-process responses). All subjects' affect-result responses were more positive (or less unpleasant) than affect-process responses. All of these results underscore the critical influence of expectations and the manner in which one evaluates sensations on affective responses to noxious stimulation.

Retrospective analysis of 22 patients with chronic pain treated by peripheral nerve stimulation.
Twenty-two patients with chronic pain, chiefly from posttraumatic neuropathy, were treated by implanted peripheral nerve stimulators located proximal to the pain. Thirteen of these (62%) have experienced pain control for an average of 25 months. ⋯ There are theoretical and practical advantages to electrical stimulation and proximal portions of the peripheral nervous system. The surgical technique for implantation is described and the necessity for reoperation in some patients is explained.
