*When asked whether anything in the [[Harry Potter (book series)|series]] reflects any of her childhood fantasies, author [[J. K. Rowling]] says, "''...who wouldn't want to be able to use the Jelly-Legs Curse?''"<ref>[http://www.accio-quote.org/articles/2000/1000-scholastic-chat.htm Scholastic interview with J. K. Rowling]</ref>. This seemingly confirms that it is a curse, rather than a jinx.

*Almost all evidence so far given suggest that this spell and the [[Jelly-Legs Jinx|jinx of the same name]]; [[Pottermore|pottermore]] often changes the title of spells (see [[Pimple Jinx|Furnunculus curse]]), the two spells have identical names except the type of [[Dark charms|dark charm]] they are, and it is highly likely that either the spell is meant to make victim's legs shake until they collapse, or else that the [[Shield Charm|shield]] used decreased the power of the spell so much so that instead of making [[Harry Potter|its intended victim's]] legs collapse, it merely made them shake. Let us not forget, also, that the aforementioned victim had an amazing amount of physical control over his body.
