Such interventions would have the potential to reduce the prevalence of chronic pain in the population .
Although certain risk factors can identify individuals who are most likely to develop chronic pain , few interventions to prevent chronic pain have been identified .
To facilitate the identification of preventive interventions , an IMMPACT meeting was convened to discuss research design considerations for clinical trials investigating the prevention of chronic pain .
We present general design considerations for prevention trials in population s that are at relatively high risk for developing chronic pain .
Prevention of post‐herpetic neuralgia: acyclovir and prednisolone versus epidural local anesthetic and methylprednisolone
Background : Treatment of herpes zoster ( HZ ) includes the use of acyclovir with or without steroids . An alternative therapy is the epidural administration of local anesthetics with or without steroids . This trial compared the efficacy of these two treatment regimens in the prevention of  post‐herpetic neuralgia ( PHN )
