Body Mechanics Flashcards
involves the coordinated effort of muscles,
bones, and the nervous system to maintain balance,
posture, and alignment during moving, transferring, and
positioning patients.
Body mechanics
The wider the base of
support,
the greater the
stability.
The lower the center of
gravity,
the greater the
stability.
The equilibrium of an
object is maintained as long
as the
line of gravity passes
through its base of support.
Facing the
_______ __ ______ prevents
abnormal twisting of
the spine.
direction of
movement
e. Dividing balanced activity
between ____ __ ___ reduces
the risk of back injury.
arms and legs
It is easier to pull, push, or
roll an object than it is to ____
lift it
Movements should be smooth
and coordinated rather than
jerky
requires
coordinated muscle activity and
neurologic integration.
Body movement
Body Movement requires four basic elements
Body alignment (posture)
Joint mobility
Balance
Coordinated movement
bring body
parts into position in a
manner that promotes
optimal balance and
maximal body function
whether the client is
standing, sitting, or lying
down.
Proper body alignment
and posture
is the maximum movement
that is possible for that joint.
ROM varies from individual to
individual and is determined by
genetic makeup, developmental
patterns, the presence or
absence of disease, and the
amount of physical activity in
which the person normally
engages.
Range of motion (ROM) of a
joint
The mechanisms involved in maintaining
_____ and _____ are complex and
involve informational inputs from the
labyrinth (inner ear), from vision
(vestibulo-ocular input), and from stretch
receptors of muscles and tendons
(vestibulospinal input). Mechanisms of
equilibrium respond frequently without
awareness.
balance and posture
is the term used to describe
awareness of posture, movement, and
changes in equilibrium and the knowledge of
position, weight, and resistance of objects in
relation to the body.
Proprioception
is the result of proper
functioning of the cerebral cortex,
cerebellum, and basal ganglia.
Balanced, smooth, purposeful
movement
The ______ ______ initiates voluntary
movement,
cerebral cortex
the ____________ coordinates
motor activity
cerebellum
maintain posture.
basal ganglia
(dynamic)
exercises are those in which
the muscle shortens to
produce muscle contraction
and active movement.
Isotonic
TRUE OF FALSE? During isotonic exercise, both
heart rate and cardiac output
quicken to increase blood flow
to all parts of the body.
TRUE
Example of Isotonic Exercises
walking, running, hiking, swimming, skiing, and dancing
exercises are those
in which there is muscle
contraction without moving
the joint (muscle length does
not change).
Isometric (static or
setting)
