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
