Report on a Trial of
the MouseBean® Hand Rest
by David Tibbs MS, FRCS. Consulting Surgeon. Oxford.
I am a retired surgeon who now uses a computer mouse over long
periods whilst preparing surgical illustrations, and I am prone
to carpal tunnel syndrome. Examining the MouseBean Hand Rest I
found that it successfully met the requirements originally
intended, so that:
- The base of the hand rests comfortably on the two cushions
without the need for any support by the fingers or the shoulder
and arm muscles. In this way, the tendons passing through the
tunnel are relaxed and this spares the median nerve from
otherwise continuous pressure.
- The gap between the two cushions ensures that no external
pressure falls upon the line of the median nerve, thus removing
this unfavourable possibility.
- Fine adjustment of the mouse position is easily made by the
fingers without raising the hand (in fact, more easily than
without the hand rest). The effortless gliding of the hand rest,
again without raising the hand, easily permits wider movement of
the mouse across the mouse pad.
- The wrist is supported in the favourable mid-position where
structures in the tunnel can operate with least stress.
- There is no difficulty in keeping the mouse and MouseBean
Hand Rest together and the hand can be raised instantly to go to
the keyboard and then readily repositioned on the hand rest.
I was quickly converted to this simple but effective device.
The annoying onset of tingling and numbness in my thumb, index
and second fingers had ceased to occur.
Note on other forms of RSI. Other varieties of RSI may
well benefit from use of the MouseBean® Hand Rest because the
hand and wrist, so well supported on this gliding device, are
relaxed. Finger movements are no longer made against unduly
tensed tendons trying to control fine movements while bearing the
weight of the unsupported hand and arm. These factors can only be
Who should use the MouseBean® Hand Rest?
Undoubtedly the MouseBean® Hand Rest is pleasing to use
and any computer operator would be well advised to use one
without waiting for the symptoms of carpal tunnel syndrome, or
any other form of RSI, to develop. Certainly, any sufferer with
mild symptoms should use a MouseBean® Hand Rest to avoid the
onset of more severe symptoms and possible lasting damage. Those
who have an established carpal tunnel syndrome may find that the
device will allow them to return to work without the need for
surgery. But why wait until your median nerve shows signs of
distress? Try it now!
About the Author:
David Tibbs is a retired surgeon who has treated many
patients with carpal tunnel syndrome (although not necessarily
related to using a computer mouse) by simple advice on wrist
positioning (such as wearing a splint overnight), or, in severe
cases, surgically to open up the tunnel by dividing its overlying
ligament. He has long been aware of his own incipient carpal
tunnel syndrome, and with his previous experience and the need to
prevent his own symptoms, he was happy to encourage John Crocker
in the development of the MouseBean® Hand Rest.
