View Full Version : Gait inverse dynamics in treadmill

Dear All,
I have two main problems using a treadmill for my experiments .
One is the classical problem to perform inverse dynamics analysis. There
are no measured G.R.F. (Ground Reaction Forces).
Two possible solutions:
1. Force platforms mounted under the treadmill(s) belt(s). DOES ANYBODY
KNOW ABOUT THEM?
I have a reference of the people in Heidelberg and Cologne that have
developed such a system.
In this case we would need two force-platforms and two treadmills (or a
double band treadmill), don't we?.
2. Measure the G.R.F. under the plantar aspect of the foot, pressure
insoles could give an estimation of the vertical component of the G.R.F.
and the point of application of the force. But only an estimation, isn't
it?. DOES ANYBODY KNOW ABOUT AN INSOLE CAPABLE OF MEASURING THE OTHER
COMPONENTS OF THE GRF?

At the moment I am trying to purchase a treadmill that could fit most of
my requirements.

Yours sincerely,
Arturo Forner-Cordero
