You will often need outpatient rehab if you have a serious illness like a heart attack, stroke, or cancer. In these cases, your treatment will often start in the hospital. When you start to get better, you will likely change to a program of occupational and physical therapy. You may also have supervised aerobic conditioning exercises a few times a week while at home.
Some illnesses, such as stroke, may need a combination of rehab programs. For instance, you may need a speech pathologist to help you learn to speak again. You may also need a physical or occupational therapist to help you learn how to walk and go about your daily activities.
