In the syndrome of post-herpetic neuralgia (PHN), the nature of the sensory disturbance and
its relationship both to the severity and cause of the pain is controversial. To address these …

Twelve otherwise healthy patients with longstanding postherpetic neuralgia (PHN) were
prospectively studied using clinical examination, infrared thermography and response to …

The relationship between deafferentation, sensory function, and pain was explored in 18
subjects with chronic postherpetic neuralgia (PHN). Subjective thresholds for warmth …

Background Postherpetic neuralgia (PHN) is considered by some investigators to be
predominantly a deafferentation-type central pain syndrome; others suggest that activity of …

Background In postherpetic neuralgia (PHN), dorsal root ganglia neurons are damaged.
According to the proposed models, PHN pain might be associated with nociceptive …

Postherpetic neuralgia (PHN) is a common and often devastatingly painful condition. It is
also one of the most extensively investigated of the neuropathic pains. Patients with PHN …

Somatic sensory perception thresholds (warm, cold, hot pain, touch, pinprick, vibration, two-
point discrimination), allodynia and skin temperature were assessed in the affected area of …

The hypothesis that the pain and allodynia associated with post-herpetic neuralgia (PHN) is
maintained by a combination of input from preserved primary afferent nociceptors and …

Background A variety of analgesics have been studied in the treatment of postherpetic
neuralgia, with several medications demonstrating some degree of efficacy. However …

Patients with sensory disturbances of painful and non-painful character show distinct
changes in touch and/or pain sensitivity. The patterns of sensory changes were compared to …
