“Is it possible to self-induce a muscle twitch in BFS? ”

I had a injury in my hamstring last month and I am on physiotherapy treatment for the same. My neurologist diagnosed me with a Benign fasciculation syndrome (BFS). I get muscular twitches around my knee and thigh area often. However, I can also induce these twitches myself by tapping my knee area. Is it possible to self induce muscular twitches?
