The Oregon Physical Therapy Association evolved from a training course for physiotherapists established at Portland's Reed College in 1918. The course prepared 200 women as "Reconstruction Aides" to assist in rehabilitating soldiers wounded in World War I. In 1921-1922, Oregon alumni from this course formed the Portland Unit of the national American Women's Therapeutic Association. Among the founding members were Ruth Babb, Cora Howes, and Minnie V. Thomas. Membership grew in the 1920s due to the expansion of local programs, including the establishment of a physical therapy department at the Shriner's Hospital for Crippled Children in Portland in 1924. In 1929 the national convention of the American Physical Therapy Association was held in Portland. From 1930 to 1953 the Oregon Physical Therapy Association was a part of the Oregon Federation of Professional Societies. In 1950, due to the emergence of physical therapy programs in Eugene, a Southern District of the organization was established. In 1954 the Oregon Physical Therapy Association became an Oregon corporation.
