Dear All
I agree with wht has been written but may I take it one step further
(terrible pun).
Vladamir Janda the father of moder rehab stated many times that the skin
of the foot is very important for all muscle motorskills, from balancing
to writing.
He also stated that reduction in balancing skills commence some 3 years
before the onset of adult diabetes. He would treat patients as diabetics
if he found their skills lacking.
I had several discussions with him over the role of the talus in the big
picture.
It is an amazing bone. Remember it has no muscles attached and thus its
actions are set my pressures applied and flexibility of the ligaments
present.
Thus there is a three point pressure approach to the bone.
- From below via the calcaneous
- From above via the tibia
- From the anterior direction via the navicular.
Thus having three points one can plot any position within this triangle.
When you look at this 3-pronged pressure sensor both the left and right
one has a mapping service to tell you where you are in relation to the
earth.
Similarly in the ear, the incus has no muscles attached to it. Around this
is the influence of the semicircular canals. These also form the three
pronged spatial imput.
Thus we have a method of controlling where we are in space. When combined
it creates where we are in time.
Very clever.
In a later email it is mentioned that climbing - we do not need it. I
agree that climbing is not needed in most countries of the world but many
an islander needs to climb to feed themselves eg coconut trees and dates
trees and the like.
I have a Pacific Islander who has size 18 feet and nearly as wide. he
climbed many a coconut tree in his life.
he has normal feet. His party trick is to lie on the ground and with
extended legs, internally rotate his feet to 90 degrees so he can clap
them. An amazing sight to say the least.
Regards,
Paul Conneely.
