Does this wrist stretch actually work?

[KayFactor]

"With hand resting in front of you with the palm up, bend your wrist as far as you can.. Then press into the area behind the wrist, where they take your pulse, and hold a good amount of pressure on it. After 30 seconds slowly open your wrist up as far as you can, release the pressure but hold your wrist open for another 30 seconds.
For best results relax your body first by taking a deep breath and exhaling then remain this relaxed."

I don't even know if I'm doing it right either

I'm skeptical of ANY wrist stretch procedure, because of the special anatomical nature of the wrist. All the soft structures that can become inflamed pass through the 8-bone tube called the carpal tunnel. Excessive stretches squeeze these structures against each other in this tube quite alot. It's why people who do relatively trivial wrist movements regularly often develop carpal tunnel syndromes. Also, stretching structures you use constantly is of dubious value. You're moving your wrist around from the moment you get out of bed (even sooner, in Fedace's case) so it's a structure that isn't likely to be very tight.

Does more wrist flexibility help ANY of your strokes...tennis related.
Say one of your wrists bends backwards only about 45 degrees. The other bends backwards close to 90, so that one can allow you to do a pushup.
Does the 45 degree bending wrist inhibit any of your strokes?
In my case, a little. Very little.
My left wrist bends back 45 degrees max. My serve is average hard for a 63 year old, getting into the lowest 100's on flat first serves.
Groundies might have less "point the handle to the ball", but groundies are stronger than most any 4.5's from the forehand side.
Volleys are easily adaquate. 4.5 to 5.0 level volleys from a 4.0 level singles player....can't blame volleys.
So what's the drawback to a wrist without flexibility? Can't do a pushup.
