There's a name for this?! I had suffered with this for years. I'm a guitarist and having your fretting hand lock up is no good! I eventually came to the conclusion I had way too much tension in my neck, shoulders, and forearm. Stuff I found online said play loose, play light in order to fix it. In order to play loose and play light I also needed to play much slower. Over a long time I've managed to build my speed back up while still playing loose and playing light. Turns out I needed to unlearn some really bad habits I'd developed decades ago when first starting to play guitar. The bad habits eventually caught up with me. But yeah, I always wondered what was wrong with me as my hand would get "frozen" with my fingers curled and my being not able to move them. I'm glad I've managed to get beyond it!
