The treatment of illnesses or injuries that limit a person’s mobility. Physical therapy management may include prescription for assistance, education, electrophysical modalities, including heat, cold, electricity, sound waves, radiation, assistive devices, prostheses, orthoses and other interventions. Instead of using drugs or surgery to minimize pain, physical therapists focus on exercises to build muscles, stretch tight muscles and retrain movement. Also known as physiotherapy, physical therapy uses evidence-based kinesiology, electrotherapy, shockwave modality, exercise prescription, joint mobilization and health education. It treats conditions such as chronic or acute pain, soft tissue injuries, cartilage damage, arthritis, gait disorders and physical impairments typically of musculoskeletal, cardiopulmonary, neurological and endocrinological origins.
