Greetings All,
The following is the tentative program for the North American Society of
Gait and Clinical Movement Analysis Second Annual Meeting in Chicago April
9-12. Those familiar with the organization know that this meeting has taken
place under a variety of titles for a number of years, but this is the
second meeting overseen by a formal, structured society. The abstract
submissions for the conference were as usual very high quality and with the
assistance from many of our collegues, we have planned what I believe to be
an excellent program. Information about conference registration can be
obtained by emailing Carolyn Moore(cmoore@nwu.edu).
Our goal is to provide the forum to fulfill NASGCMA’s mission to stimulate
and advance research, professional interaction and exchange of ideas as
related to human movement in clinical settings. On behalf of the Scientific
Program Committee, we encourage your attendance and participation in
NASGCMA’s 2nd Annual Meeting and look forward to seeing you in the Windy
City in a couple months.
Take Care
