PRINCIPLES OF BODY MECHANICS

What is important to determine before moving an object?

• The object's colour

• The object's shape

• The object's weight

• The object's material

You are going to carry your laundry basket across the room. What is the first thing you should do?

• Clear objects from the path

• Pick up the laundry basket

• Pick up objects as you carry the laundry basket

• Determine how far you have to walk

What should you do to ensure good body mechanics?

• Ignore the environment

• Move quickly

• Plan the movement

• Avoid using supports

What should you do to protect your back when moving objects?

• Slouch slightly

• Lean forward

• Maintain the spine in a neutral position

• Bend backward

Where should the weight of the object be placed when moving it?

• Close to your COG

• Far from your body

• Above your head

• At arm's length

What needs to remain inside the base of support to maintain balance?

What is the primary benefit of facing the direction of movement?

• It increases speed

• It prevents twisting of the spine

• It improves balance

• It decreases speed

How would you correct the pictured lift?

• Direct the client to pull the box across the floor.

• Direct the client to pull the box towards his head.

• No corrections are needed as client is demonstrating good mechanics.

• Direct the client to bend the knees.

What is the safest alternative to lifting heavy objects?

• Pushing

• Pulling

• Using an assistive device

• Bending at the knees

What is the benefit of reducing friction between surfaces when moving an object?

• It increases the force required

• It makes the surfaces rougher

• It decreases the force required

• It makes the surfaces smoother
