View Full Version : More Spasticity Measurement..

Hello Everyone,

Garth Johnson's request for information about spasticity
measurement prompted me to just broadcast this message about my project.

I am studying for a masters degree in biomedical engineering at the
University of Surrey. I am doing my research project on the measurement
of spasticity in the lower leg muscles of stroke patients who are
using functional electrical stimulation to correct 'dropped-foot'. A
long title but most scientific research has to be identified in detail
I guess.

I am using passive movement of the ankle to elicit the stretch
reflex response. I am getting there, but, there is still so much I
have to learn about the intricacies of spasticity and its measurement.
For my project, I actually have to design and build a clinical test
rig. I am using a motor driven footplate which will be driven at
constant angular speeds. I am trying to initially measure the torque
by monitoring the current demanded by the motor since a force
transducer/load cell would be much too expensive for my meager
project budget.

I'd just like to know if anyone had any experience in building
a rig from scratch and taking measurements with load cell/force transducers
or by monitoring the current into the motor. Any other comments ?????

Thanks for your attention,
