Dear all
I received three responses to my request recalled below. Thank you very
much to all those who took the time to help me. Regards.
Original question:
"I am looking for informations on trauma at the neck level due to
wearing a helmet while walking or standing a long time. This topic is of
obvious interest to armies (foot soldiers wearing heavy helmets); some
sports may also be interested in such research. Although I was told
injuries have been reported I can not find any published field data nor
experimental or modeling study of head with helmet in
walking/running/standing situations (not in impact situations). I would
greatly appreciate if anybody could provide references of published
papers on the subject. Of course I will make the results available to
the group. Thanks in advance,
Quentin Grimal, Ph.D"
Response 1:
You may try the US Air Force Research Labs (http://www.afrl.af.mil/ ). I
am sure there is some information about helmet injuries there. Mary G.

Response 2:
I just posted the following reference in my weekly literature update. It
has nothing specifically to do with helmets or chronic stress, but it
does address injuries to the neck during high accelerations.
Coakwell MR, Bloswick DS, Moser R (2004) High-risk head and neck movements
at high G and interventions to reduce associated neck injury. Aviation Space
and Environmental Medicine 75: 68-80
I'm sure there are plenty of references for high acceleration neck
injuries within the general "trauma biomechanics" community. You may
want to also survey the literature on tissues and biomaterials for creep
tests on intervertebral discs, cartilage, etc. Best,

Response 3:
You are correct that there is very little information on neck loading
due to helmet wearing. The only research I know about was done quite a
long time ago -- the references are as follows:
Phillips, CA, Petrofsky, JS. A computer model of neck muscle endurance
and fatigue as a function of helmet loading.
Comput Biol Med. 1986; 16(2): 103-30.
Phillips, CA, Petrofsky, JS.Cardiovascular responses to isometric neck
muscle contractions: results after dynamic exercise with various
headgear loading configurations. Aviat Space Environ Med. 1984 Aug;
55(8): 740-5.
Phillips, CA, Petrofsky, JS. Neck muscle loading and fatigue: systematic
variation of headgear weight and center-of-gravity.
Aviat Space Environ Med. 1983 Oct; 54(10): 901-5.
Phillips, CA, Petrofsky, JS. Quantitative electromyography: response of
the neck muscles to conventional helmet loading.
Aviat Space Environ Med. 1983 May; 54(5): 452-7.
Petrofsky, JS, Phillips, CA.The strength-endurance relationship in
skeletal muscle: its application to helmet design.
Aviat Space Environ Med. 1982 Apr; 53(4): 365-9
I look forward to the posting of the results.
