Physiotherapy involves physical therapists assessing patients' movement abilities and creating goals in collaboration with other health professionals using skills unique to physical therapy. The field has its origins in ancient practices like massage and hydrotherapy and was institutionalized in the late 19th century. Today, physiotherapists work in hospitals, clinics, and private offices using techniques like soft tissue mobilization, strengthening exercises, and electrical stimulation to treat patients across various specialties like orthopedics, neurology, and oncology.
