YIPS is an involuntary movement (flinch, jerk) that happens to golfers when they putt or chip. This infuriating twitch has caused many a golfer to increase what would otherwise have been a perfectly respectable handicap. To the untrained eye, it looks like a clear-cut case of nerves kicking in at a crucial moment. But the way Mayo Clinic neurologist Charles H. Adler sees it, the yips might not be psychological at all; in fact, they may have their roots in the nervous system.
