Clinical Trial Summary

if amifampridine can improve neuromuscular transmission in muscles previously injected with OnabotulinumtoxinA (BTX-A)


Description:

Amifampridine may also be effective in treating the sequelae of botulinum toxin injections and this study will determine if neuromuscular transmission as measured by single fiber electromyography is improved in patients treated with BTX-A following administration of amifampridine
