简要总结
The investigators will investigate golfers with visual evidence of an involuntary movement while putting before and after treatment with a low dose of propranolol.
详细描述
Dystonia affecting athletes has received little research attention and there has been a lack of awareness or interest among both physicians and athletes. Task-specific dystonias or occupational cramps affect people while writing, typing, and or playing a musical instrument. Our group has previously shown that a subset of golfers who complain of the yips appear to have a task-specific dystonia or golfer's cramp. The yips are characterized by an inability to appropriately complete a golf stroke, most often putting and chipping strokes. Most individuals with the yips describe a jerking or shaking movement that interrupts their swing. In many cases the yips are disabling and the golfer, including professional tour players, give up golfing.
Golfers who have evidence of golfer's cramp will putt a series of putts during which they will be monitored for arm movements and putter movements. They will then be treated with a low dose of propranolol to see if there is a change in these parameters.

研究组 & 干预措施
Golfers With Golfer's Cramp
Subjects in this arm will be tested with the Opal device, the Science and Motion PuttLab (SAM), and the Surface Electromyography (EMG) to collect movement parameters while putting before and after a single dose of 10 mg Propranolol.
干预措施: Propranolol (Drug)

结局指标
主要结局
Mean Dynamic Change of Rotation at Impact
时间窗: baseline, approximately 45 minutes after propranolol dosing
"Dynamic change of rotation at impact" is the velocity of rotation of the putter from the start of the forward swing until the time of impact with the golf ball.
次要结局
- Mean Total Putter Face Rotation Before Impact(baseline, approximately 45 minutes after propranolol dosing)
