The following are the responses:

I have been working on "turning while walking" for a couple of years.
Through our literature survey, no clean data was found on the percentage
of falls happened in turning while walking. However, one study by Cumming
and Klinberg said that a fall from turning when walking could have as many
as 7 times higher rates in leading to hip fractures than a fall from
walking straight. Related information could be found in:

Cao C., Ashton-Miller J.A., Schultz A.B., and Alexander N.B.
Effects of age and gender on abilities to turn suddenly when walking.
J. Gerontol.: Med. Sci., 1997.

Could you post a summary or a simple note to me? Thanks.

Take a look at Albert King's work and Steve Goldstein.

We have recently completed some lab-based studies regarding falls and
slips when walking in a straight path or one with a turn. Currently, we
are in the process of compiling the data from this study, which would
include a "frequency of falls recorded". The freq would be correlated to
all the risk factors studied in this project (lighting, load carriage,
surface slipperiness,... etc.).

I would be greatly interested in obtaining a copy of the responses you
receive to your query. Please forward me a copy of the responses you
receive. Esp., statistics that relate to workplace (field studies).

Thank you.

At the 27th Oct you have sent a message to the Biomch-L server regarding
literature of fall statistics during gait. I am/was facing the same
problems and it seems that there are not a lot of studies around in this
area. The ones I have are the following:

Prudham D & Grimley-Evans J "Factors associated with falls in the elderly:
a community study" Age and Ageing 1981; 10: 141-146

Speechley M & Tinetti M " Falls and injuries in frail and vigorous
community elderly persons"
Am Geriatr Soc 1991; 39: 46-52

Myers AH, Young Y and Langlois JA "Prevention of falls in the elderly"
Bone 1996 Jan.; 18(1) (Suppl): 87S-101S

The last one is a big review classifying studies according their topics. So
this might also be of some help. It would be nice if you could send me a
summary of your answers as I am still looking for some other studies done
in this related field.

With kind regards
Margrit Meier

Dear Mr Chen
Probably you have read the papers I mention, but if this could be of
help:
There is a good bibliographic review about falls in the elderly:
"Prevention of Falls in the Elderly" by Myers,
Young and Langlois in Bone Vol. 18 No. 1 Supplement
January 1996:87S-101S.
Also, you could check these:
1) "Patient Falls and related variables". Leighbody, Andrews and Long.
Proc. Human Factors Soc.-29th Annual Meeting- 1985
2) "Environmental and Behavioral Circumstances Associated with Falls at
Home Among Healthy Elderly Individuals". Connell and Wolf. Arch
Phys.Med Rehabil Vol. 78. February 1997.
This paper is the only one that makes an in-depth examination of the
cause of the falls studied.
I am interested also in this topic.
Yours sincerely

The VA Palo Alto, CA has conducted balance studies for at least 6 years now.
They should be on the web. They might be able to help.
