Résumé

INTRODUCTION: Sleep disorders presenting involuntary movements may be very annoying to patients, apart from their negative influence on sleep. OBJECTIVE: To report the use of botulinum type-A toxin (BoNT-A) to manage the case of a patient whose sleep was severely disrupted by episodes of dystonic posturing of the right lower limb triggered by periodic limb movements of sleep (PLMS). METHOD: A 79-year-old woman with mild post-stroke right hemiparesis presented with recurrent painful episodes of dystonia of the right lower limb, which disrupted her sleep. The dystonic episodes could also be voluntarily triggered by extension of the right hallux. Polysomnography confirmed that the dystonic episodes were triggered by PLMS. Twenty units of BoNT-A (20U/500U vial) were injected into her right extensor hallucis longus. RESULTS: Shortly after BoNT-A was injected, the dystonic symptoms abated, and the patient achieved better sleep efficiency. CONCLUSION: The PLMS-related involuntary extension of the hallux was probably triggering the nocturnal post-stroke lower limb dystonic paroxysms. BoNT-A injection into the right extensor hallucis longus was effective in managing this condition and thus resolved the associated disruption of sleep.


INTRODUÇÃO: Desordens do sono apresentando movimentos involuntários podem ser bastante perturbadoras aos pacientes, além de sua influência negativa no sono. OBJETIVO: Descrever o uso da toxina botulínica tipo-A (BoNT-A) no manejo do caso de um paciente cujo sono estava gravemente fragmentado por episódios de distonia do membro inferior direito, desencadeados por movimentos periódicos do sono (MPS). MÉTODO: Uma paciente com 79 anos portadora de hemiparesia direita leve seqüelar a isquemia cerebral (AVCI) procurou-nos por episódios dolorosos recorrentes de distonia noturna de seu membro inferior direito, os quais fragmentavam seu sono. Os episódios de distonia também podiam ser desencadeados voluntariamente, por extensão do hálux direito. Uma polisonografia confirmou que os episódios distônicos eram desencadeados pelos MPS. Vinte unidades de BoNT-A (20 U/frasco de 500 U) foram injetadas no seu extensor longo do hálux. RESULTADOS: Alguns dias após a injeção de BoNT-A os sintomas distônicos regrediram, e o sono da paciente tornou-se eficiente. CONCLUSÃO: As extensões involuntárias do hálux relacionadas aos movimentos periódicos do sono estavam provavelmente desencadeando os paroxismos distônicos noturnos pós-AVCI. A injeção de BoNT-A no extensor longo do hálux foi eficaz no manejo desta condição, resolvedo assim a fragmentação do sono.

Résumé

Periodic limb movement disorder (PLMD) is one of the commonest neurological disorders and causes significant disability, if left untreated. However, it is rarely diagnosed in clinical practice, probably due to lack of awareness and/or lack of necessary diagnostic facilities. Restless leg syndrome (RLS), aging, pregnancy, uraemia, iron deficiency, polyneuropathy are some of the common causes of secondary PLMD. Clinical presentation, polysomnographic findings and management of six patients of PLMD have been discussed in this report.
