Occupational therapists (OT) can show you ways to make activities of daily living, such as cooking and showering, easier and provide advice on useful aids or equipment.
OTs can provide advice on how to do things in a way that reduces joint strain and pain and teach you strategies to protect the mobility of your joints, particularly those in you hands. They may also suggest changes to your house, such as new taps, or aids that can make life easier and protect your joints.
You can find an occupational therapist via the Occupational Therapy Australia website.
