Physical therapy (PT), also known as physiotherapy, is a healthcare profession, as well as the care provided by physical therapists who promote, maintain, or restore health through patient education, physical intervention, disease prevention, and health promotion. Physical therapist is the term used for such professionals in the United States, and physiotherapist is the term used in many other countries. The career has many specialties including musculoskeletal, orthopedics, cardiopulmonary, neurology, endocrinology, sports medicine, geriatrics, pediatrics, women's health, wound care and electromyography. PTs practice in many settings, both public and private. In addition to clinical practice, other aspects of physical therapy practice include research, education, consultation, and health administration. Physical therapy is provided as a primary care treatment or alongside, or in conjunction with, other medical services. In some jurisdictions, such as the United Kingdom, physical therapists may have the authority to prescribe medication. Overview Physical therapy addresses the illnesses or injuries that limit a person's abilities to move and perform functional activities in their daily lives.[3] PTs use an individual's history and physical examination to arrive at a diagnosis and establish a management plan and, when necessary, incorporate the results of laboratory and imaging studies like X-rays, CT-scan, or MRI findings. Physical therapists can use sonography to diagnose and manage common musculoskeletal, nerve, and pulmonary conditions. Electrodiagnostic testing (e.g., electromyograms and nerve conduction velocity testing) may also be used. PT management commonly includes prescription of or assistance with specific exercises, manual therapy, and manipulation, mechanical devices such as traction, education, electrophysical modalities which include heat, cold, electricity, sound waves, radiation, assistive devices, prostheses, orthoses, and other interventions. In addition, PTs work with individuals to prevent the loss of mobility before it occurs by developing fitness and wellness-oriented programs for healthier and more active lifestyles, providing services to individuals and populations to develop, maintain, and restore maximum movement and functional ability throughout the lifespan. This includes providing treatment in circumstances where movement and function are threatened by aging, injury, disease, or environmental factors. Functional movement is central to what it means to be healthy. Physical therapy is a professional career that has many specialties including musculoskeletal, orthopedics, cardiopulmonary, neurology, endocrinology, sports medicine, geriatrics, pediatrics, women's health, wound care and electromyography. Neurological rehabilitation is, in particular, a rapidly emerging field. PTs practice in many settings, such as privately-owned physical therapy clinics, outpatient clinics or offices, health and wellness clinics, rehabilitation hospital facilities, skilled nursing facilities, extended care facilities, private homes, education and research centers, schools, hospices, industrial and these workplaces or other occupational environments, fitness centers and sports training facilities. Physical therapists also practice in non-patient care roles such as health policy, health insurance, health care administration and as health care executives. Physical therapists are involved in the medical-legal field serving as experts, performing peer review and independent medical examinations. Education varies greatly by country. The span of education ranges from some countries having little formal education to others having doctoral degrees and post-doctoral residencies and fellowships. Regarding its relationship to other healthcare professions, physiotherapy is one of the allied health professions.[13][14][15][16] World Physiotherapy has signed a "memorandum of understanding" with the four other members of the World Health Professions Alliance "to enhance their joint collaboration on protecting and investing in the health workforce to provide safe, quality and equitable care in all settings". History Exercise to shoulder and elbow to increase motion following fracture and dislocation of humerus is being given by an Army therapist to a soldier patient. Physicians like Hippocrates and later Galen are believed to have been the first practitioners of physical therapy, advocating massage, manual therapy techniques and hydrotherapy to treat people in 460 BC. After the development of orthopedics in the eighteenth century, machines like the Gymnasticon were developed to treat gout and similar diseases by systematic exercise of the joints, similar to later developments in physical therapy. The earliest documented origins of actual physical therapy as a professional group date back to Per Henrik Ling, "Father of Swedish Gymnastics," who founded the Royal Central Institute of Gymnastics (RCIG) in 1813 for manipulation, and exercise. Up until 2014, the Swedish word for a physical therapist was sjukgymnast = someone involved in gymnastics for those who are ill, but the title was then changed to fysioterapeut (physiotherapist), the word used in the other Scandinavian countries. In 1887, PTs were given official registration by Sweden's National Board of Health and Welfare. Other countries soon followed. In 1894, four nurses in Great Britain formed the Chartered Society of Physiotherapy. The School of Physiotherapy at the University of Otago in New Zealand in 1913, and the United States 1914 Reed College in Portland, Oregon, which graduated "reconstruction aides."Since the profession's inception, spinal manipulative therapy has been a component of the physical therapist practice. Modern physical therapy was established towards the end of the 19th century due to events that affected on a global scale, which called for rapid advances in physical therapy. Following this, American orthopedic surgeons began treating children with disabilities and employed women trained in physical education, and remedial exercise. These treatments were further applied and promoted during the Polio outbreak of 1916. During the First World War, women were recruited to work with and restore physical function to injured soldiers, and the field of physical therapy was institutionalized. In 1918 the term "Reconstruction Aide" was used to refer to individuals practicing physical therapy. The first school of physical therapy was established at Walter Reed Army Hospital in Washington, D.C., following the outbreak of World War I. Treatment through the 1940s primarily consisted of exercise, massage, and traction. Manipulative procedures to the spine and extremity joints began to be practiced, especially in the British Commonwealth countries, in the early 1950s. Around the time polio vaccines were developed, physical therapists became a normal occurrence in hospitals throughout North America and Europe. In the late 1950s, physical therapists started to move beyond hospital-based practice to outpatient orthopedic clinics, public schools, colleges/universities health-centres, geriatric settings (skilled nursing facilities), rehabilitation centers and medical centers. Specialization in physical therapy in the U.S. occurred in 1974, with the Orthopaedic Section of the APTA being formed for those physical therapists specializing in orthopedics. In the same year, the International Federation of Orthopaedic Manipulative Physical Therapists was formed, which has ever since played an important role in advancing manual therapy worldwide. An international organization for the profession is the World Confederation for Physical Therapy (WCPT). It was founded in 1951 and has operated under the brand name World Physiotherapy since 2020.
