Physical therapy (PT), also known as physiotherapy, is one of the allied health professions that, by using mechanical force and movements (bio-mechanics or kinesiology), manual therapy, exercise therapy, and electrotherapy, remediates impairments and promotes mobility and function. Physical therapy is used to improve a patient's quality of life through examination, diagnosis, prognosis and physical intervention. It is performed by physical therapists (known as physiotherapists in many countries). In addition to clinical practice, other activities encompassed in the physical therapy profession include research, education, consultation and administration. Physical therapy services may be provided as primary care treatment or alongside, or in conjunction with, other medical services.
