PC Body Mechanics

notes

TermDefinition
body mechanics safe and efficient use of the body using scientific reasoning based on kinesiology and physiology
goal of body mechanics conserve energy, decrease stress & strain, prevent injury
forces gravity & friction
center of gravity (COG) point where mass is equally distributed
base of support (BOS) part of object in contact with support surface
line of gravity perpendicular line thru COG & BOS
ways to improve stability 1)decrease COG 2)centralize COG over BOS 3)increase size of BOS 4)increase weight
other rules every action has equal and opposite reaction/ increase mobility-decrease stability & vice versa
COG in the body about S2 in adults
BOS in body changes according to position
anatomy of disc nucleus populous-soft / annulus fibrosus-tough
purpose of disc gives mobility & acts as shock absorber & flexibility
imbibing fills with fluid at night
area of the disc @ risk for injury with flexion posterior
area of the disc @ risk for injury with extension anterior
area of the disc @ risk for injury with flex/rotation posterior/lateral
lever system weight of object + upper body X 10
dynamic support trunk muscles are like a corset
when lifting... use legs
sprain soft tissue injury to joint
osteoarthritis wearing out/may cause bone spurs
mm strain tearing of muscle
types of disc injury tearing, bulging, rupture, herniation (HNP)
forces causing back injury can be... prolonged forces, repetitive, or could be one time big thing
laminectomy removal of part of bone or disc
discectomy removal of whole disc
fusion vertebrae fused together
increased lordosis... caused by anterior pelvic tilt, lumbar ext, hip flexors
decreased lordosis... caused by posterior pelvic tilt, abs, hip extensors (glut. max)
pelvic tilt is determined by... the movement of the anterior superior iliac spine (ASIS)
lateral plumbline thru ear, thru acromium, just posterior to hip joint axis (greater trochanter), just anterior to knee axis, just anterior to ankle axis (laterl malleolus)

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
