Micro-movement is a term used by physical therapists usually in relation
to RSI-type injuries. In this case it refers to utilising an incredibly
small portion of the big range of movement available in the shoulder
joint. Chuck in some poor posture, long hours and a bit of stress and
things can get very unpleasant.

It's moving the whole mouse around that is a problem for some people
since the movement comes not only from the wrist but also from the
shoulder, and small repeated movements can encourage inflammation and
spasm. Once that is in place you get into a vicious circle, with less
movement required to cause more inflammation and spasm.

Old-style mice with their attendant gunk problems are a real nightmare,
and using one of these for about 30 mins is enough to flare my neck and
shoulder up a treat!

So, whilst laser mice and good ergonomic design might lessen the damage
in comparison to one of these, it might not be enough to get the patient
pain-free.

The trackball requires little or no movement from the shoulder since you
pretty much put all of the weight of your arm down onto the base and let
the fingers do the rest, allowing the shoulder to relax and relieve
tension in the neck.
