Physiotherapists treat patients with physical difficulties resulting from illness, injury, disability or aging. They treat people of all ages including children, the elderly, stroke patients and people with sports injuries.Physiotherapists work with patients to identify and improve their movement and function. They help promote their patients' health and wellbeing, and assist the rehabilitation process by developing and restoring body systems, in particular the neuromuscular, musculoskeletal, cardiovascular and respiratory systems. They devise and review treatment programs, comprising manual therapy, movement, exercise and the application of technological equipment, e.g. ultrasound. Physiotherapists also provide advice on how to avoid injury.
