ACTIVE MOVEMENTS. 89
2. Bound, i.e. movements made either while steadiness and
isolation are secured by apparatus, or under resistance.
Those made under resistance are again subdivided into
—
(a) Those in which the operator resists.
(&) Those in which the patient resists.
The second group of movements, as can readily be understood,
may be made to alternate for the same muscles, as for instance
in the case of flexion and extension of the forearm on the upper,
when the operator makes resistance to the bending and the
patient to the stretching of the forearm.
It is necessary, before the commencement of each movement,
that the patient should take up a correct position. By that I
do not only mean a position in which the exercise can be best
execvited, but also one in which the chest is free, while deep and
steady respiration must be kept up. In the movements, for
instance, with the arms, depicted in figs. 62 and 63, the
respiration niust be so regulated that deep inspiration is made
when the arms are separated from the chest, and expiration when
they are again approximated to it, because in the former case
the chest is expanded, in the latter its capacity is diminished.
Simultaneously with the quickening of the cn-culation, a
greater amount of blood is sent to the lungs, carrying with it
more carbonic acid ; and the need for oxygen in the body is
greater, thus necessitating stronger and deeper respiration.
Indeed, a correct position is nearly of as much importance as
the movement itself.
Every active exercise must be made, or given, slowly, exception
being taken in those movements by which we desire, through
their very rapidity, to influence the circulation. After the
completion of a movement,—say stretching of the arms,—the
patient remains for a few seconds with them in that position, in
order that as great an effect as possible may be produced.
We must also bear in mind that the muscular power is
strongest at the middle, smallest a^ the beginning and end, of
the movement ;
and therefore the resistance must be graduated,
