Correct the mistake: Patient is reaching for a box on top of the refrigerator. They place a step stool to reach the box. They bring down the box with arms extended and step down rapidly
Bring the box closer to you with arms shorten and step down slowly
Define: BOS and COG
1)Base of Support. 2)Center of Gravity
What lifting technique is used for lifting light objects?

Answer- Bring box closer to COG
Define Body Mechanics
The use of one’s body to produce motion that is safe, energy-conserving, and anatomically and physiologically efficient and maintains body balance and control.
What lifting technique involves bringing object closer to your COG?
Traditional lift
What are 2 ways that objects should be carried to maintain safe body mechanics?
In front at the waist or on your back
Correct the Mistake: Patient bends over with both legs straight to lift a heavy item off the ground.
Answer- Bend legs and lift with legs not back
Name at LEAST 7 out of the 9 Basic Principles of Body Mechanics
1)Position your COG as close as possible to the COG of the object being lifted.2)Increase BOS.3)Lower COG.4)Keep COG within BOS.5)Avoid Twisting.6)Maintain slow and Consistent Speed.7)Maintain Lumbar lordosis.8)Push/pull before lifting.9)Tighten core.
What is Half-kneeling lift?
Kneel on one knee, lift object onto thigh, rise to standing
