View Full Version : responses to trip and fall

Thanks to all who took the time to respond to my
question regarding the kinematics of trip and fall.
I received some excellent information which will be extremely
helpful. Following are the reponses.

Hsieh-Ching Chen partially considered this problem in his
1993 Ph.D Thesis in Mechanical Engineering at the University
of Michigan, Ann Arbor. You can get it through interlibrary
loan or University Microfilms, Inc. See the last chapter on
the modeling of recovery from a forward fall.

We have investigated slipping during the early stance phase of walking. This
usually leads to backward slipping, but there might be some useful
information for you in the following publications:

Strandberg L and Lanshammar H
The dynamics of slipping accidents. Journal of Occupational Accidents, 3, pp
153 162, 1981.

Strandberg L and Lanshammar H
On the biomechanics of slipping accidents. Biomechanics VIII A, eds. H.
Matsui, K. Kobayashi, Human Kinetic Publishers, Champain, Illinois, pp 397
402, 1982.

John Brault,

If you have access to any online search mechanisms (e.g., medline), then
you might try doing an author search on Mark Grabiner of the Cleveland
Clinic Foundation. He's been known to trip up a few people (for scientific
purposes of course). Good luck on your search for info.

John (and Jeff?),
For information concerning the kinematics/kinetics of slips
and falls, you might try contacting two persons who did some
work on this (gait on slippery surfaces) while at the Univ. of
Massachusetts. They are:
Tim Eng (now at Nike in Oregon, sorry no more address info) and
Dennis O'Connor (now at Steadman Sports Medicine Foundation
in Vail, CO. Phone: 303.479.9797 x276).
For references on slips and falls you may want to try the
gerontology literature and the postural control literature--
while much of the literature may be on the elderly, young
groups are often used for comparison.
Good luck,

Dear Jeff,

Here are some references that I pulled out from my gait
bibliography. The word "fall" also selected the time of year so
ignore those references! Hope this helps.

I think Bob Andres and some of his students at the University of
Massachusetts published some slip and fall data within the last five years.

Dear John ...
You should start by looking at the ASTM Symposiums on Slip and Fall Research
- I'm sure you will find some interesting research in the proceedings. You
may also look for some work done by Jim McElhaney of Duke University - he ran
several experiments where he purposely tried to induce trip incidences. I'm
sure he must make some comments regarding reflex response.

Dear John,

We have just got a paper published in Experimental Brain Research. The
reference is Eng, JJ, Winter, DA and Patla, AE. Strategies for recovery
from a trip in early and late swing during human walking. Experimental
Brain Research, 102, 339-349, 1994. It deals mainly with the EMG and
kinematics from a motor control perspective. For my doctoral dissertation
I actually performed a three-dimensional kinematic, kinetic, and total body
centre of mass analysis of tripping. I'm in the midst of trying to
get the kinetics published. Hope you find the reference useful.

Dear John

Following are the two references about falls and stepping over obstacles.
Hope these will help.

young and old adults, 46(9), 196-203.

Gerontology, 48(3), 97-102.
