Re: Centrifugal Force

[Dr. Chris Kirtley]

Dear all,

I'm sure I'm not the only one to find this discussion fascinating -
especially for its practical implications (now that accelerometers are
becoming so cheap) for measuring motion without an inertial frame, and
for the motor control implications.

As far as I know, we have no sensors for segment acceleration - only
(conceivably) joint angular acceleration, via spindles, joint afferents
and skin receptors. Would this variable be sufficient, I wonder, for the
CNS to compute the inverse dynamics?
