Hello everyone. I'm from the Philippines. My brother has had an injury related to tennis for almost 2 years. It's like his arm (whole arm and shoulder) twitches and then drops on its own when he's about to strike a forehand or a serve. It's like he can't control his arm and he has a hard time swinging it. This also happens to him when he is playing basketball. We've tried MRIs, nerve tests, therapies and strengthening exercises, but nothing has worked so far. I have a video if anyone is interested.
