Muscles are controlled
by the brain with nerves in the same way your computer turns on when you give it power. the term muscle memory is just an expression and apart from that how to hold a pencil probably won't be affected as that function is done with a different part of the brain it usually just affects memory like people names, phone numbers, or where you work. but things like how to drive a car may stay with you. PS I know this post was just a joke based on the title for discussion but I felt the need to answer it anyway! if you have any real concerns consult your doctor!
