Signs of hyperpathia in chronic peripheral neuropathic pain.

ABSTRACT:

Background

Neuropathic pain is pain due to a disease or lesion of the somatosensory system, and can be either spontaneous, evoked or both. Hyperpathia is a type of evoked pain defined by IASP as 'a painful syndrome characterized by an abnormally painful reaction to a stimulus, especially a repetitive stimulus, as well as an increased threshold'. The literature is sparse, and definitions are unclear and inconsistent.

Methods

The aim of this study was to examine for the presence of mechanical hyperpathia in a heterogeneous group of patients with peripheral neuropathic pain and correlate signs of hyperpathia with other sensory signs. Patients were examined with graded pinprick stimuli to obtain a stimulus-response curve and repetitive pinprick stimuli to assess increase in pain
