THE TAKEAWAY
Athletes who play sports that require precision movements commonly develop the yips. While the prevailing theory among athletes is that this is a psychological phenomenon, evidence shows that this may in fact be a neurologic focal dystonia caused by repetitive use. Greater awareness of yips as a possible organic, treatable neurologic condition is needed in order to stimulate more research on this topic.
