Many thanks to everyone that replied to my question regarding marker
attachment. Evidently the study of biomechanics has caused substantial
hair loss, because toupee tape seems to be the solution of choice. In
addition there were a variey of spray-on adhesive skin preps and
Super-glue. Replies are compiled below.
1. You could try spirit gum...used to attach fake mustaches, etc. We
used
it to attach markers before.
2. I have used a skin glue by the brand name of "Stomahesive" to attach
small plastic jigs to the lateral malleoli and knee joint lines of
individuals while they performed a knee bending exercise. To each
jig we
attached an LED for use with an OPTOTRAK system.
The "Stomahesive", which is in effect a glue that is used to attach
colostomy bags, etc. is an easy to use skin glue that holds up well
for
the tasks that I have used it for. How it would work with your
calcaneal
device I am not sure, but my experience tells me that it holds up
well as
skin temperature rises and when a subject perspires. It also washes
off
relatively easily from the skin surface and can be washed from the
plastic surface immediately after use or at a later date. When
using
this glue, it is important to not use too little or too much to
achieve
optimal adhesion.
I purchased the glue at a medical supply store, one that was located
close to a hospital setting. I hope this is of some help. Good
luck.
3. Have you tried Animal mesh tape? If yes, read no further. It's a
sort
of 'clingy, sticky' tape wrap used to adhere splints and wound
wraps
especially for animals.
I haven't worked in a motion lab in years and therefore haven't
purchased the stuff in an equal amount of time. But, I bet your
friendly vet would know what I'm talking about and refer you to an
appropriate catalog to order it.
4. I had good luck using Quick Dry Adhesive (QDA) spray to prep the
skin
before applying tape. Its a commor Athletic Training supply.
5. While at the university of guelph, i learned that crazy glue works
only in
tension, not in torsion. we used it to glue everything from
markers to
accelerometers to skin! one just needs to be sure that the area is
free from
hair, that not too much glue is used, and to use a quick twisting
motion to
remove the marker. your subjects may be skeptical, but it does
work!
6. try sleek tape.
7. You don't say what sort of tape that you have been using or how long
the
trials are...
I've always found that toupee tape works very well for holding
markers onto
subjects - it's double sided and designed to hold to sweaty skin.
One
precaution that you could take would be to use an eyebrow liner
pencil to mark
the outline of your plastic marker holder so that it can be replaced
when it
falls off.
8. Have you thought about superglue or the tape used on "breathe-right"
stickers?
9. Many years ago, Julian Morris of Oxford Metrics introduced me to a
double-
sided tape that is made for attaching wigs to scalps. It comes in a
roll
attached to a non-stick paper backing and has no stiff plastic sheet
in the
middle like conventional double-sided tape does. That is, the tape
is
essentially a layer of adhesive without any backing. Once the tape
is
attached to the skin and the paper removed, the adhesive is free to
change
shape as the skin changes shape. The tape is very sticky and may be
worth a
try. We found some at a theatrical supply store.
You might also try double-sided foam tape. Because the foam backing
has some
flexibility, it may stay attached better than other tapes.
Good luck in your quest. It is hard to tape things to feet, isn't
it!
10. I've used double-sided EMG/ECG electrode tape to affix flexible
markers
to the skin surface over the midline of the spine. On a clean
surface,
this tape performed well with skin distraction. I've also seen
rubber
cement used to affix surface markers for gait studies, although I
don't
know if there might be any toxic substance absorbed throught the
skin.
11. there is a spray used by athletic trainers that goes on before
applying
tape. this spray provides a better surface for the athletic
tape. you
might try this
12. We use a similar method where we attach a shell to the calcaneus
and must change orthotic conditions. We first put Cramer quick
drying
adhesive (QDA) on the skin. It comes in a spray can and is often
seen (and
smelled) in training rooms. The tape we use is commonly called
"McConnell's" tape. If you are not familiar with it, it is a brown
tape,
1 1/2 inches wide, very strong and very sticky. The brand we use
is from
Smith and Nephew but there are other brands out there. Hope this
helps.
13. Try carpet tape. Its double sided, and holds on very well.
14. Have you tried the type of double-stick tape which is used
to attach men's hair pieces? This "toupee tape" is very
sticky and holds firmly. We get it from a beauty
supply house. Perhaps a figure 8 or heel lock around the
plastic form, provided it is not too bulky. Best of luck.
15. We have used super glue to attach accelerometers to the skin
of the wrist. It worked well and the sensors easily came off
with the superficial layers of dry skin. We did not have to
remove them surgically as some might fear. I don't know how
that would work inside the shoe but you might want to give it
a try. Use small drops to start with, do not try to cover the
whole mold because that may be too much glue on the skin.
16. A similar problem was overcome by the team below, by using modified
running shoes, which had the posterior heel counter removed, and
transparent plastic riveted in place of the heel counter. (I
forget
which it was?) These were described in the paper I give details of
below, and came from Nike.

foot
orthoses on rearfoot mechanics

17. A fellow graduate student at Ohio State used toupee tape to hold on
finger markers. Worked pretty well.
