There is absolutely no relationship whatsoever.
I don't think anyone was actually proffering a direct neurological
relationship between the face and hands. The basic idea is that one
should avoid unnecessary stress and wasted energy where it accomplishes
nothing. It accomplishes nothing in your mouth and jaw, but more
important is that one should relax their hands. I think relaxing your
face just works as an reminder to relax in general. Likely being told to
relax your shoulders would likely help your hands too. Or closing your
eyes and taking a few deep breaths first.
I saw an opera last week and baritone Simon Keenlyside had an arduous
role. When asked him about how he dealt with the demands, he said he
tried to calm himself by "backing out" of the drama. I thought it a
curious thing for an actor to say. It was only by releasing some of the
dramatic intensity that he was able to more easily relax and take care
of the vocal tasks. I'm not sure of the nerve routing for vocals, but I
think relaxation is something we do consciously to control our emotions
and stress and then it works out from there.
This was The Tempest by Thomas Adès, role of Prospero which Adès has
said he wrote with Keenlyside in mind.
OT: Another great thing Keenlyside said was this: He said an opera
singer's voice was like a shoe: At first it's shiny and perfectly shaped
but somewhat uncomfortable and ill-fitting, much later it's comfortable
as hell but is worn and lost much of its beauty. Only in the middle is
it both pretty AND comfortable, and he hoped he would stay in that zone
for many years to come. Great exit line.
It is.
I didn't see Andy's post directly. I wouldn't oversell the lack of a neurological connection between the face and hands.
It is true of course that both sensory and motor circuits of different body parts are separate. But they all converge in the sensory and motor cortex. So they ARE related indirectly.
An intriguing classical experiment in this regard was the series of "split brain" experiments.
For the interested, here's a (large) pdf scan of the article as it appeared back in the 1960s, when Scientific American was a real science magazine:

I didn't see Andy's post at all. However to say there is no relationship between the hands and the brain is truly erroneous.
The realm of Yoga establishes just that, a co-existence between the mind and the body. While there is an acknowledgement in the two being separated spatially, the actual difference between the two is taken to be minimal.
Western Philosphy has always sought to diferentiate the mind from the body and to compartmentalize the two such that one has nothing to do with the other. This leads to a somewhat convenient way of dealing with things and ultimately cuts many things short.
Eastern philosophy generally counteracts this. In India at least, a peaceful and disclipined mind is taken to be mirrored in one's physical being. When ending a session of Yoga generally the word "Om" is uttered in a drawn out fashion three times to calm the mind and dissipate thoughts. The word spelled in english is actually misleading.
When we look at the actual Devanagri script of the word Om, http://pleasurepointyoga.com/wp-content/uploads/2012/03/om.jpg
we can see that it actually consists of 3 parts. The first being the actual symbol that kind of looks like a 3. The second being the seeming tale that originates from the 3 and the third being the crescent shaped moon kind of symbol above parts 1 and 2. This is the way Om or AUM is written.
The word is therefore really "Aum", Three syllables, A, U, M. When saying it out loud, you can shorten the "m" sounding part of it or the "au" sounding part of depending on the effec toyu want it to have. Thus "au" is to signify physical well-being and the "m" is to signify mental well-being as they both resonate in different parts of the body when you say it out loud.
The "au" resonates in the rib-cage and the abdominal region while the "m" part of it resonates in the skull.
Of course this has nothing to with proving that the hands are tied to the brain, but of course scientifically as Steven pointed out, they still are.
