Hi Mark,

responding your question concerning the use of gloves, you will find a
short summary and good references in: Chaffin, D.B.; Andersson, G.B.J.;
Martin, B.J.: Occupational Biomechanics, Third Edition. John Wiley &
Sons,
Inc., p. 449-450 (1999). Particularly he points out:

Putz-Anderson, V.: Cumulative trauma disorders: A manual for
musculoskeletal diseases of the upper limbs. Taylor & Francis,
Philadelphia
(1988).

Riley, M.W.; Cochran, D.J.; Schanbacher, C.A.: Force capability
differences
due to gloves. Ergonomics, 28 (2), 441-447 (1985).

Mital, A.; Kuo, T.; Faard, H.F.: A quantitative evaluation of gloves
used
with non-powered hand tools in routine maintenance tasks. Ergonomics, 37
(2), 333-343 (1994).

Additionally we would be interested in your results as we developed a
mathematical model of the fingers to calculate the force transmission at
the participating biological structures.

George Torrens :

I have just given a paper on glove
evaluation and development at the International Soldier System
Conference,
Bath. Some of your colleagues were there, Mr David Goyne gave a paper.

Mr Goyne should have a copy of my paper, but if you'd like more
information
and other associated papers I can put them in the post.

What isn't covered in the paper is that I've developed ways of
customising
gloves to optimise fit, haptic and dexterity performance.

I'm also about to start working with Will Tutton and Emma Westwood, R&PS
(formerly part of DLO and DTCA befrore that). Emma's my current project
manager for the handwear. Will and Emma want me to look at concept
designs
for footwear and technology demonstrators.

"Justin Keogh" :

Dear Mark,

You could use von Frey filaments to test tactile sensitivity, as they
are used by neurolgists / GP's for this. Depending on the glove size
and make, von Frey filaments may not be able to be felt at all
though.

Kelly Cole :

I seem to remember a study by Kinoshita examining changes in fingertip
forces during manipulation from different glove thicknesses.

"Poletto, Chris (NINDS)" :

Mark,
I know that NASA did a lot of this research some years ago because of
effect
of bulky space suit gloves on manual dexterity. They may have ongoing
research as well. I do not have the particulars in front of me, but
thought
this might point you in the right direction. The other thing you may
wish to
look at would be activities of daily living (ADL) tasks that have been
developed to evaluate disability in CNS damaged patient populations. One
such paper is:

Wijman CA, Stroh KC, Van Doren CL, Thrope GB, Peckham PH, Keith MW.
Functional evaluation of quadriplegic patients using a hand
neuroprosthesis.
Arch Phys Med Rehabil. 1990 Dec;71(13):1053-7.

Stavdahl Řyvind :

Mark,
some of the aspects of gloves that you mention are very relevant for
so-called "cosmetic gloves" for hand prostheses, i.e. the
prosthesis "skin".
This is especially true for factors such as friction and resistance top
deformation, the latter whish drastically influences the energy
consumption
of the prosthesis. Therefore you might want to cross-post your request
to
the OANDP-L list at . Many members of that
list are researchers and practitians in theprosthetics field.
