Abstract:
Background:Resting tremor is a prominent cardinal motor symptom of Parkinson’s disease (PD). In some cases, the tremor may be refractory to dopaminergic and anticholinergic treatment. Multiple studies were previously done to evaluate the effectiveness of Botulinum Neurotoxin A (BoNT/A) with essential tremors and dystonia, but data regarding its use on tremors of PD is still lacking.
Objective:This meta-analytic study aims to determine the effectiveness of BoNT/A in treating tremors of patients with PD.
Data Sources:Data Sources: Researches were searched at PubMed, ScienceDirect and EBSCO Host.
Review Methods:Articles on the effect of BoNT/A on PD hand tremors were searched. Studies and data pertaining to non-PD tremors like essential tremors excluded in the analysis due to difference in pathophysiology. Standardized mean difference was used as the effect measure and was computed with Review Manager version 5.4 software.
Results:Three open label studies were used for final analysis in this study. Studies included are those pertaining to tremors due to PD. Pooled estimates showed a significant change in decreasing tremor score after BoNT/A injection.
Conclusion:Botulinum Toxin A injections can be used to manage PD tremors effectively.
