Physiotherapy aims to prevent and treat impairments through physical examination, evaluation, diagnosis and intervention. It promotes mobility, functional abilities and quality of life. Physiotherapists assess, diagnose, treat and evaluate patients to restore optimal physical function and movement. Physiotherapy can benefit patients with orthopedic, neurological, cardiac, pulmonary, burns and many other conditions through techniques like exercises, modalities, manual therapy and airway clearance. It is commonly used to treat pain, increase range of motion and strength, improve balance and prevent complications from immobility.
