Normal Walking Tutorial
The purpose of this homework assignment is to give you
practice thinking about concepts related to gait
biomechanics. To complete the gait tutorial, go to the New
Media Center and check out the CD entitled "Normal
Walking." To view the CD, put the CD in any Macintosh at
the NMC, and double click on its icon when it appears on the
desktop.
Here's what you need to do:
You will see several options. You need to select the Easy
Test, the Medium Test, and the Hard Test, and then answer
only the questions that are identified on the following
pages for each of the tests. Keep these test sheets for your
review.
To get credit (10 pts):
- Email Dr. Gross (mgross@umich.edu).
- - Put "330-H9" in the subject line (1 pt)
- - In the body of the message, state your name (1
pt), and what you found interesting or useful in these
tests (8 pts)
