title: Long-term consequences of upper extremity peripheral neuropathy in former Vietnam prisoners of war.
abstract: BACKGROUND
  At the time of repatriation in 1973, a substantial number of Vietnam prisoners of war (POWs) were diagnosed with upper extremity peripheral neuropathy (UEPN).
  
  
  OBJECTIVE
  To assess the long-term functional consequences of UEPN among former Vietnam POWs diagnosed with UEPN at repatriation.
  
  
  METHODS
  Former POWs with an International Classification of Diseases, Eighth Revision, code of peripheral neuropathy identified from a central database registry.
  
  
  METHODS
  Cross-sectional survey. Standardized survey instruments and the SF-12 questionnaire were mailed to all subjects. A subsample of subjects completing the mailed survey was contacted by telephone to complete a semistructured questionnaire on current symptoms and physical limitations attributable to peripheral neuropathy.
  
  
  RESULTS
  Seventy-nine percent of POWs diagnosed with peripheral neuropathy at repatriation currently experience some numbness or tingling more than 25 years after repatriation, and 63% currently experience pain in one or both hands. Although the average severity rating for numbness and pain was mild, 23% of the POWs still have moderate to severe pain. Ulnar neuropathy was present in more than 30% of the POWs. SF-12 physical composite scores were substantially lower among this group of POWs compared with an age-matched group from the Medical Outcomes Study.
  
  
  CONCLUSIONS
  For those POWs diagnosed with UEPN at repatriation, nearly 80% continue to experience symptoms of numbness, tingling, and pain, with nearly 25% reporting a moderate or greater degree of symptoms. The low physical function scores of this cohort are particularly troubling. More research concerning physical symptoms and conditions among former POWs is needed, and this research should also investigate what causes are responsible for the significantly lower physical functional status.
