Respect Pain! Pain is the body's way of telling us that something is wrong. Rule: pain that lasts more than 1-2 hours after completing the task means that the task was too stressful. Break up the task next time into smaller parts.
Maintain muscle strength and muscle range of motion. Use each joint to it's maximum available range of motion. Example: when ironing, use long flowing strokes, straightening and bending the arm as much as possible.
Avoid positions that put stress on affected joints. The "normal" way of doing something may be needed to change so joints are stabilized. Example: holding a knife with the whole hand instead of just fingers
