Dear Colleagues,
Thanks to all who responded. I especially appreciate those who delved into the archives of their personal paper files - whew - a daunting task. I know because that is what I did before I posed the question. I think it makes sense that, as found by one person, Hans Lehneis, PhD, CO first came up with the SMO in NY. In JPO > 1989 Vol. 2, Num. 1 Nancy Hylton reports she has been developing Dynamic AFOs since 1971. Also, It should be noted that from what I have read by Nancy Hylton, PT, she NEVER calls her Dynamic AFO a SMO.
Thanks for all your assistance. If anyone has any more evidence and would like to share it would be appreciated.
Don
ORIGINAL QUERY:Dear Colleagues,
I have been searching the literature for the first mention of the SMO. I have come up empty, it seems everything I have found so far mentions SMOs as a common device. My recollection is SMOs came about from PTs trying to stabilize feet with low temp materials so they brought the more flexible material higher and wrapped it
around the foot more. But I have found nothing in the lit to confirm that story.
If you have any ideas to pursue I would appreciate knowing them.
Thank you,
Don McGovern, CPO, FAAOP
RESPONSES---------------------------------------Don, try the early stuff on Tone Inhibitive Orthoses for a lead on SMOs. I brought Don Bluthorn (sp?) into Chicago for a Midwest Chapter meeting and that was where I first heard the term. CascadeDAFO might have something for you. Bev Cusak may also be a lead for the same reason. I was involved with the first ISPO CP conference which gave us a ReCal lit search but I don't recall any specific articles on SMOs per say. Bev had extra lit at the meeting. Good Hunting. May make for an interesting article. Terry

The first article to appear in JPO 1989 Vol.2 num 1. pp 40-53 is the firstarticle to discuss
SMO's as DAFO dynamic foot orthosis. The first mention of
a SMO was in the early development of the UCBL and laminated AFO's of the
late 60's and 70's. The laminated SMO was discussed at NYU and UC Berkley as
an alternative to metal foot orthotics in treating children with major foot
and ankle deformities. Unfortunately I could not find the article from my
old school notes from lower extremity orthotics (NYU 74). The problem with
the laminated SMO was they were too thick and rigid and limited AP motion
while controlling the ML. The practitioners discussed the new and coming
options of vacuum forming with sheet materials. THE SAME RESPONDENT FOLLOWED UP WITH THIS:After peaking my interest, I started to look further. The first mention of the SMO is of a low profile laminated AFO for CP kids. It was done by Dr. Leinheis at the Rusk Institute for Rehabilitation at NYU back in 1969. The article was published in the Bulletin of Prosthetic Research as an addendum to the UC-BL article of Spring 1969.
Following that the development of the NYU Insert Orthosis was the first use of a laminated foot shell attached to metal uprights creating the first hybrid AFO. The article was written by V.T. Inman in January 1969 :UC-BL Dual Axis Ankle Control System and UC-BL Shoe Insert. Came out of the University of California Biomedical Laboratory , San Francisco and Berkley . The Physical Therapy articles begin in earnest in the early to mid 80’s--------------------------------------Check out CascadeDafo's <URL Redacted>
-------------------------------------------
Contact Nancy Hylton, CO, PT, (originator of the DAFO concept) to trace the
origins. If she didn't do
it, she'll know who did.
