Objective Determine whether propranolol or looking at the hole when putting improves the yips.

Background

Some golfers with the yips have a task-specific dystonia, golfer’s cramp, while others do not. Response to treatments have not previously been reported.

Design/Methods

Five golfers with the yips due to dystonic golfer’s cramp and 9 with the yips not appearing dystonic completed 10 two-handed putts looking at the ball, the hole, and right hand only, and 10 two-handed and right hand only putts following 10 mg of oral propranolol. Surface EMG analyzed wrist muscle co-contraction. Logistic regression with robust variance estimate to account for within subject correlation was used to test if there were group difference and condition difference for yips and co-occurrence yips.

Results Golfers with dystonic yips yipped 84% of putts two-handed looking at the ball, 68% looking at the hole (p<.001), 52% following propranolol (p<.001). Non-dystonic yips had 31.1% (p=.003 compared to dystonic group), 32.2%, and 26.7%, respectively. Right hand only the dystonic group yipped 86% of putts before and after propranolol, non-dystonic group 82.2% before and 58.9% after propranolol (NS). In the dystonic group co-contraction and a yipped putt co-occurred 70% of two hand looking at hole, 46% looking at the hole (p<.001), and 18% following propranolol (p<.001). Non-dystonic yips group had 12.2% (p=.009 compared to dystonic group), 12.2%, and 13.3%, respectively. Right hand only the dystonic group had a yip with co-contraction 62% of putts before and after propranolol, the non-dystonic group 52.2% before and 37.8% after propranolol (NS).

Conclusions Both propranolol treatment and looking at the hole improved the two-handed yips due to dystonic golfer’s cramp, but not non-dystonic yips. Yips right hand only did not improve for either group after propranolol. Despite being a small study, we have identified methods and potential treatments for yips due to dystonic golfer’s cramp.
