High prevalence of neuropathic pain in the hand of patients with traumatic brachial plexus injury: a cross-sectional study

ABSTRACT

Objective To describe the pain profile of patients with traumatic brachial plexus injury.

Methods We enrolled 65 patients with traumatic brachial plexus injury. The Douleur Neuropathique 4 questionnaire was used to classify pain and the SF-36 was used to evaluate quality of life.

Results The patients with traumatic brachial plexus injury were predominantly young male victims of motorcycle accidents. Pain was present in 75.4% of the individuals and 79% presented with neuropathic pain, mostly located in the hands (30.41%). The use of auxiliary devices (p = 0.05) and marital status (p = 0.03) were both independent predictors of pain. Pain also impacted negatively on the quality of life (p = 0.001).

Conclusions Pain is frequent in patients with traumatic brachial plexus injury. Despite the peripheral nervous system injury, nociceptive pain is not unusual. Pain evaluation, including validated instruments, is essential to guide optimal clinical management of patients with the condition.

RESUMO

Objetivo Descrever o perfil de dor de sujeitos com lesão traumática do plexo braquial.

Métodos Nós incluímos 65 indivíduos com lesão traumática do plexo braquial. O Douleur Neuropathique 4 foi usado para classificar a dor e o SF-36 foi usado para avaliar a qualidade de vida.

Resultados Sujeitos com lesão traumática do plexo braquial eram em sua maioria homens jovens, vítimas de acidentes motociclísticos. A dor esteve presete em 75.4% dos indivíduos e 79% deles apresentaram dor neuropática, mais frequentemente localizada nas mãos (30.41%). O uso de dispositivos auxiliares (p = 0.05) e o estado civil foram, ambos, preditores independentes de dor. A dor ainda impactou negativamente da qualidade de vida (p = 0.001).

Conclusões A dor é frequente em sujeitos com lesão traumática do plexo braquial. Apesar de envolver uma lesão do sistema nervoso a dor nociceptiva não é infrequente. A avaliação da dor, incluindo instrumentos validados, é essencial para direcionar as condutas clínicas de sujeitos com esta condição.
