Physically hands will shake and then it will be an explosion. It will be a quick jerk. I think that's physical. Now a new Mayo Clinic study shows the yips are largely a physical problem. They found that jerk usually occurs on downhill putts, right to left, when your body's in a certain posture.
Researchers think that posture helps cause that yip.
That may also explain why long-putters help the problem, because they change your posture. Now a medication may help, too. It's called Inderal and it eases shaking, tremors, and twitching. Amateurs swear by the medication, but Fitzgerald says the pros avoid it. They worry it will dull their senses.
