How do you define the yips?
The yips is a term used by golfers to describe an involuntary movement — a twist, a jerk or a shake — that usually happens when putting, although some people will describe it when doing other activities like chipping.
What makes you think there's more to this than golfers choking at a crucial moment?
There are a number of people who have a neurological illness called dystonia, which can cause cramps or pulling in the fingers or wrist while doing a specific task. It's known to occur in writers and musicians — in many cases the only time that they have a problem is when they are trying to perform a task related to their writing or music. In between they are completely normal.
We're trying to determine if there are some golfers who have a golfer's cramp that would be equitable to writer's or musician's cramps.
