Horseback riding in children with cerebral palsy: effect on gross motor function
We define sports therapy as the enjoyment of any sport whichresults in improvements in gross motor function for individ-
uals having neurological disorders or developmental disabil-ities. The introduction of sports therapy in the early formativeyears may have a significant impact on accelerating the reha-
bilitation of children with neurological disorders or develop-mental disabilities, such as cerebral palsy (CP).
CP is a chronic condition often requiring lifelong participa-
tion in physical and occupational therapy (PT, OT). In additionto standard PT and OT to improve motor function, it has beenour clinical experience that parents often inquire about sports

Historically, horseback riding has been subjectively described

measure the clinical efficacy of horseback riding as therapy.
There are no further references in the literature to the use
of horseback riding as a form of therapy until two serious epi-demics of paralytic poliomyelitis in Scandinavia in 1946. These events led to the founding of the first two centers oftherapeutic horseback riding in Copenhagen, Denmark and
Oslo, Norway for the treatment of children with neuromus-
cular disorders, especially poliomyelitis and CP (Baine 1965).
From 1953 onward, therapeutic horseback riding was
actively promoted by the International Polio Fellowship in
England (Baine 1965). This international momentum for
HBRT led to the development of the first therapeutic riding
program in North America established in Toronto, Canada in1965 as the Community Association for Riding for the
Disabled (CARD; Brock 1988, Mackay-Lyons et al. 1988). The
