some thoughts on balance:-
I like the image of the weighing scales
in postural control this image translates into the level at which someone
can hold things together. For instance to say that a person who has had a
stroke has no balance is not helpful, it is more useful to consider that
person as having a level of balance. In this sense we all have a level of
balance, and because of that fact we have the potential to change for better
or worse. A truly therapeutic intervention is one that raises the level of
order in a person's system, such that the person is more balanced, more
integrated.
equilibrium suggests a balance point between two (or more) poles or
polarities, again the weighing scales are a good image. I would tend to
regard the word equilibrium as having a more subtle quality, something more
refined than balance in the broader sense. In this way of thinking one might
have a level of balance without being at the point of equilibrium?
having looked at the Collins English Dictionary definitions
balance:- 3. a state of equilibrium. 5. equilibrium of the body;
steadiness: to lose one's balance. 6. emotional stability; calmness of mind.
7. harmony in the parts of the whole: balance in an artistic composition. 13
a balancing movement. from late Latin bilanx having two scale pans, from bi-
+ lanx = scale
equilibrium:- 6. Physiol. a state of bodily balance, maintained primarily by
special receptors in the inner ear.
I would tend to reserve equilibrium to use in connection with the
vestibulospinal system.
Is that helpful?
