Nothing at all about stress relieving.

Pressing on the rim, against the axle end, will untwist spokes but it
is
difficult to press hard enough to relieve internal stresses in
individual spokes that way. Better to add a step: wearing heavy
gloves, grasp pairs of spokes and squeeze hard, repeating all around
the
wheel. Done properly, this will practically eliminate the need for
later truing and the spokes will last a long, long, time.

Dear Ted,

Outside of posts on rec.bicycles.tech and references to
Jobst's book, do you know of any studies, tests, or web
pages that address what we're calling "stress relieving" and
"stress relief"?

The quotation marks are used only to broaden the question,
since there may be other names and methods for
spoke-squeezing, as well as other claims for the process is
supposed to do to the spokes.

Sheldon Brown, for example, quotes Jobst, but gives the
spokes a twist with a smooth crank arm instead of squeezing
them:

It would be interesting to find out if Japanese Keirin
bicycle mechanics squeeze or twist spokes. Maybe John Dacey
knows?

Might be worth a look.
