also known as restoration
goal is to restore or remediate client factors that are impaired

How do levers apply to OT?
We help the client. So maybe they dont have enough force, we may then adapt the way they do the activity. When washing dishes you need lots of torque, if they dont have a lot we can have them move closer to the sink which will lower amount of torque needed.
