Their job is to help people with the movement of their bodies. They help with problems linked to bones, muscles, the heart, lungs and circulation.
People may need to see a physiotherapist for a number of reasons. They might have had an accident or be ill. Or it might just be that they're getting old!
You'll find physiotherapists in most hospitals. They work in lots of areas, from the outpatients department to the Intensive Care Unit (ICU).
In the ICU they are needed to give chest physiotherapy to help unconscious patients (patients who are not awake and alert) to breathe.
