Akbal and Julie;
In general functional hallux limitus is more of a problem in walking
than in running. Dr. Dananberg has likened FnHL to an overuse syndrome
while walking and I completely agree. With short periods of running, or
with very efficient runners, I don't see dramatic problems due to FnHL. To
clarify that, understand that the athletes' and runners who see me for foot
complaints usually spend a lot more time walking around than running!
Now, depending on the severity of the symptamatology that I feel is
caused or exacerbated by the FnHL, the patients may or may not have any
problems while running. Some of them do, and usually they have to curtail
their running mileage.
Why would running not tend to be as bad w/ FnHL, as in walking. Well
for one, we take approximately 2000 strides per limb per day walking. We
may stride more frequently while running, but rarely will runn past one
hour.
As far as the mechanics of running, I believe that the swing limb and
energy storage of the limbs provide a much more efficient mechanism for
forward propulsion and can lend to a shortned midstance period and quickly
move into active propulsion.
Late midstance propulsion elongation is the problematic period for FnHL
symptoms, as I see it. It seems to me that in general, running is easier
for transition in this period, at least until I get fatigued!!! Then it can
be a bitch! That is my experience only, and I wear custom orthotics!!!
Hope this helps.
Bruce
