BODY MECHANICS
- efficient use of body as a machine
*force
*object
*fulcrum
- purpose of good mechanics:
*promotes good musculoskeletal
function
*reduces required energy

*bend knees slightly to avoid strain (act
as shock absorbers)
- proper posture:
*pull buttocks in and hold abdomen in
(helps keep a straight back)
*hold chest up and slightly forward
*hold head erect with face forward and
chin slightly in
- body at work:

*promotes balance

*longest and strongest muscles to
provide energy

*promotes safety of patient and
healthcare worker

*internal girdle is the long midriff to
protect abdominal muscles

- terms:

*feet apart for a wide base support

*alignment – having parts in proper
relationship to each other

*push, pull, or roll objects when possible

*balance – steady position
*base of support – area on which object
rests
*gravity – force pulling object toward the
center of the Earth

REMINDERS FOR A GOOD BODY
MECHANIC:
*bend at knees and hips
*use leg muscles

*center of gravity – area on which mass
of object is centered

*keep back straight when lifting

*line of gravity – vertical line that passes
through center of gravity

*rest between periods of exertions

*center of gravity and balance – stable
position, center of gravity must be above
the base of support
- posture:
*position of body
*feet parallel, flat on floor, shoulder
width apart

*avoid twisting and stretching muscles

CONCEPTS OF MOVING A
PATIENT/CLIENT:
*friction – force that opposes motion
*force – energy required
*inertia – rest at rest, motion in motion
*muscle – produces force that moves
lever

*fulcrum – fixed point about which a
lever moves (ex
