Survey of Canadian Physician Use of Botulinum Toxin A (BoNT-A) for Paratonia: Real World Insights.

Paratonia is a form of hypertonia characterized by an inability to relax muscles in the setting of cognitive impairment. Paratonia results in pain, refusal of care, and caregiver burden. We sent surveys to 67 Canadian physiatrists and neurologists regarding their experience treating paratonia with botulinum toxin A (BoNT-A). Twenty-seven survey respondents were included in the analysis. Thirteen percent of survey respondents treating paratonia with BoNT-A reported a significant clinically relevant improvement; 74% endorsed a moderately clinically relevant improvement; 13% endorsed a slight clinically relevant improvement. Ninety percent of survey respondents endorsed significant barriers in treating paratonia with BoNT-A.
