"Flinch", "yips" in golfers, and a host of other movement disorders are now classified as a 'Task Specific Dystonia'

The problem has ended the careers of some professional golfers and musicians. Aynsley Smith PhD, Director of Sports Pyschology and Sports Medicine Research at the Mayo Clinic, Rochester, has researched the problem extensively http://www.radiology.medscape.com/viewarticle/411176

Michael Keyes, M.D. discussed the 'Yips' on p. 28 of the Sept. 05' Shotguns Sports Magazine

I've previously shared that I've been forced to stop shooting trap. No one is interested in my medical problems, but the explaination is illustrative and complex related to:
1. Otosclerosis-a familial problem causing tinnitus, loss of hearing, and dysequilibrium (dizzyness)
2. Several previous sports and MVA related head injuries causing dysequilibrium (and likely explains some squishy brain behaviour)
3. A familial problem with involuntary myoclonic jerking/fine resting tremor that may be associated with head titubation (involuntary head shaking)
4. Bad osteoarthritis in my neck and back
5. Way too much trap (with a M-12) and sporting clays with 1 1/8 loads

I frequently 'flinch' trying to click the mouse on the computer! And trust me, I've tried every 'cure' short of a release trigger. My point is that a 'flinch' is as real as Parkinsonism and the causes and cure thereof can be terribly complex. Give guys a break when discussing it, because it's unbelievably frustrating to have no control over something as simple as pulling a trigger or swinging a putter, especially when doing that gives us such joy.
