The Australian bush nurse who challenged the medical establishment to revolutionize polio treatment

In short: Elizabeth Kenny was a self-taught nurse who defied standard medical practice by rejecting limb immobilization for polio patients. Instead, she pioneered a method using hot, moist compresses and physical movement. Though initially dismissed as a fraud by many professionals, her techniques eventually became the foundation of modern physical therapy.

Born in 1880 in rural New South Wales, Elizabeth Kenny lacked formal nursing credentials but gained practical experience through volunteer work and observation. Her approach to polio emerged from a desire to alleviate the intense pain and muscle spasms suffered by children. Guided by the advice of surgeon Aeneas McDonnell, she moved away from the then-standard practice of using splints, braces, and plaster casts to immobilize limbs, which often led to skeletal and muscular deformity.

Kenny’s method focused on applying damp heat to affected areas to reduce pain, followed by the systematic bending and flexing of joints to restore function. Despite her success in rural clinics, she faced decades of intense opposition from the medical community, which viewed her as an outsider. Her struggle was exacerbated by the fact that she maintained that polio was a viral infection of muscle tissues rather than the nervous system, a theory that contradicted the prevailing scientific consensus of the time.

After failing to gain traction in Australia and England, Kenny traveled to the United States in 1940. She eventually secured space at the Minneapolis General Hospital, where her results earned her widespread acclaim. By 1942, she established the Sister Kenny Institute in Minnesota. While her methods were later overshadowed by the success of polio vaccines, her work fundamentally shifted the approach to rehabilitation, cementing her legacy as a pioneer of physiotherapy.

Her life and professional battles were famously chronicled in the 1946 film Sister Kenny. Despite her international fame and honorary degrees, she remained a polarizing figure in her home country, where her contributions were largely ignored until after her death in 1952. Today, she is recognized for her persistence in the face of an intransigent medical establishment and her lasting impact on patient care.
