TEN COMMANDMENTS OF
BODY MECHANICS:
Implement the following when positioning/moving/ ambulating patients
1) Clue the client in:
Be sure the client knows what you are going to do, how you are going to do it, and how they can help. Take your time! Plan!
2) Get help:
If it's too much for you to handle, REGARDLESS of weight (equipment or patients)
3) Check your footing:
Your feet should be 12-18 inches apart to give you a broad base of support for better balance & stability. Place one foot slightly in front of other for better balance side to side & back & forth
4) Move close:
Instead of reaching from a distance. Move in and hold object close to your center of gravity, concentrating the mass in the pelvic area)
5) Squat:
Don't use mobility (back) muscles. Bend hips & knees & keep back straight. LET YOUR LEGS DO THE WORK!
6) Lift:
Use work (thigh) muscles by strengthening your legs
7) Be smooth & synchronized:
Avoid stain produced by jerky movements; GET together- (it's a good idea to count 1-2-3) w/the person helping you. The person w/heavier load counts & gives clues
8) Turn-Don't Twist:
Shift position of your feet to turn - don't twist your body. Twisting pulls muscles & may cause back strain. PIVOT w/feet. Turn w/short steps & turn whole body
9 -10) Don't lift:

Teach & Preach:
It's safier & easier to pull or push an object. USE A DRAW SHEET!
The "GOOD" word to others - so all of us will lift well & safely
Normal Movement consists of:

1) Body Alignment/Posture
Consists of 3 things:
a) Line of Gravity - Vertical line falls from center of gravity thru base of support
b) Center of Gravity - Avg. location of wt. of an object; the line of gravity is a Vertical line
c) Base of Support - The foundation (i.e. your feet); if the VL from CG does NOT fall thru the BofS the body loses balance
2) Joint Mobility

a) AROM:
b) PROM:
Funcional unit of Musculoskeletal syst; depends on ROM
a) Active ROM - person's own movement of a joint
b) Passive ROM - someone else moves joint for person (not a independant movement)
