More in
relation to cycling and walking fast swinging arms.
Steady
balance in cycling is dependent on speed, toppling off at zero speed.
A comfort
zone is there. So with walking.
I have seen
Parkinsonics ‘shuffle’ forwards - but walking fast.

Dear Nandana,
I am glad
that you sent me the U-Tube clip on Parkinson's tremor and rigidity being
reduced / subdued by repetitive wilful activity (ie:-cycling) or exercise (ie:-
dancing) ...
I can't formulate a hypothesis to explain it but it is interesting that these activities gives (what I fathom is) temporary relief, perhaps sustained for hours or days but "not a cure"
Perhaps cholinergic over activity seen in Parkinson disease in face of reduced dopamine, is in some manner
1. bypassed ... or

when cycling or dancing so that there is in someway a release of 'a reserve' of Dopamine from basal ganglia.

f-MRI studies
might give a clue as to the physiology.
The
observation that chances of falling (in the older subject) who are faster may
seem a paradox, but it is a fact that if one slows down and "is
careful" .... the chances of falling are much greater.
If a "fast individual" were to trip over there would be automatic reflex protective movement.
If a "fast individual" were to trip over there would be automatic reflex protective movement.
In the case
of a older individual the reflex protective postural changes to regain balance
would be gradually lost as spontaneity is reduced 'when being careful' having
to consciously think of basic movements such as walking.
sincerely,
Jaika
