Measure
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.
Golf Pros
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. The subjects in this arm will not receive any study drug.

PRIMARY outcome

Timeframe: baseline, approximately 45 minutes after propranolol dosing

Population: This variable was measured at baseline and then again approximately 45 minutes after propranolol in the group with golfer's cramp on the same day. The pro golfers did not take propranolol so they were only tested once, at baseline.

"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.

SECONDARY outcome

Timeframe: baseline, approximately 45 minutes after propranolol dosing

Population: This variable was measured at baseline and then again approximately 45 minutes after propranolol in the group with golfer's cramp on the same day. The pro golfers did not take propranolol so they were only tested once, at baseline.

"Total putter face rotation before impact" is the degrees of rotation of the putter from the start of the forward swing until the time of impact with the golf ball.
