What is balance?
Balance is an ability of an individual to control,
restore and regulate the COM [centre of mass] of the
body automatically without thinking.
Following stroke, when one side of the body muscles
are weak, paralyzed and may be they are spastic as
well, it is unable to control, restore and regulate the
COM against the force of gravity. This leads to….
Automatic switch of control of balance to the non
paretic good side by selforganizing brain for; safety
of COM is a priority for all living organism.
With balance control switched to good non paretic side by self-
organized brain following stroke, the story does not end rather it
Self-organized brain also wants to secure the safety of COM by
unloading the paretic lower limb of the responsibility of the
large inertial mass of the head arm trunk to be born on the
paretic hip, it endorses the mechanical unloading of paretic hip
from unopposed pull of normal trunk muscles by neural
endorsement of ongoing peripheral input from normal
peripheral nervous system[PNS]
Unloading of lower limb results in consequential effect on the
proprioceptors in the muscle and joint receptors. I believe that
instead of poor proprioception there is hyper proprioception /
hyperesthesia from unloading to make reloading of paretic
lower limb an impossible task thereby maintain COM safety
with good side.
Invisible changes begin to take place to
enable the entire body to continue to
function with paretic side of the body
behaving differently in the 3 dimensional
space during postural tasks when
movement of COM needs to be controlled
and restricted within the safe territory of
good side of the central axis the vertebral
Walking in 3 dimensional space.
The imaginary balancing point of the body, the
COM in a stroke subject shifts towards the good
