Dear Subscribers,

Sarah Sullivan, Rutgers, The State University of New Jersey, will be giving
a free webcast presentation on Thursday November 8 (NB: Friday Nov. 9 in
some places of the world):

Adjusting the Axle Placement in Wheelchair Users to Minimize Shoulder Joint

This webcast is a demonstration of the construction and validation of a
model of an individual with paraplegia propelling a wheelchair. This
anthropometrically accurate model is driven kinematically with motion
capture data and kinetically with recorded x-, y-, and z- forces from
force-sensing push rims. Two validation techniques are used to build
confidence in the model: 1.) experimental subject EMG activity is compared
to corresponding muscle activity as calculated by AnyBody, and 2.) the
torque (as opposed to the individual force-components) as calculated from
the force-sensing push rims drives the model and the resulting force
components are compared to the original push rim force outputs. With
confidence in the model, we look at utilizing the AnyBody modeling system
for quantitatively comparing the axle placement in wheelchair set-up and its
effect on shoulder joint forces.

To accommodate viewers from different sides of the planet we are running the
presentation twice with 12 hours interval:

First show: Thursday November 8th 09:00AM EST (New York)

Second show: Thursday November 8th 09:00PM EST (New York)

The duration of the webcast is approximately one hour including Q&A.

The event is free but it is necessary to sign up to participate. Please do
