This document addresses hippotherapy, also referred to as equine movement therapy, which has been proposed as a type of physical, occupational, or speech and language therapy.  This treatment strategy utilizes equine movement for individuals with impaired movement related to spastic cerebral palsy and other motor dysfunctions.

Position Statement

Investigational and Not Medically Necessary:

Hippotherapy is considered investigational and not medically necessary in all cases.


There is insufficient scientific data in the peer-reviewed medical literature to support the effectiveness of hippotherapy for the treatment of individuals with cerebral palsy or other motor dysfunction such as arthritis, multiple sclerosis, head injury, and stroke.

The majority of the literature regarding hippotherapy consists of small case series published in the German literature. English language publications also consist of small case series (Benda, 2003; McGibbon, 1998). Sterba and colleagues (2002) reported on the outcomes of horseback riding in 17 subjects with cerebral palsy. Gross motor function measurements were assessed before and after a once weekly horseback riding program for 18 weeks. Gross motor function total scores improved by 7.6% after 18 weeks, returning to baseline 6 weeks after the program ended. This small trial is inadequate to permit scientific conclusions.

An updated literature search based on the MEDLINE database through February 2015 did not identify any new literature to support the use of hippotherapy for those with spastic cerebral palsy and other motor dysfunctions.


Hippotherapy, also referred to as equine movement therapy, describes a form of physical, occupational or speech and language therapy using horses. It is a form of therapeutic horseback riding or equestrian therapy. This treatment strategy has been proposed as a technique to decrease the energy requirements and improve walking in individuals with cerebral palsy. It is thought that the natural swaying motion of the horse induces a pelvic movement in the rider that simulates human ambulation. In addition, variations in the horse's movements can also prompt natural equilibrium movements in the rider. To attain specific postural responses, the therapist may place the rider in different positions on the horse, such as sitting, side sitting, prone or side lying. In many cases, the therapist will ride with the rider in order to facilitate the movement or desired response.

Hippotherapy has also been proposed as a therapeutic treatment for other disorders or conditions such as traumatic brain injury, stroke, multiple sclerosis, autism, spina bifida, learning disabilities, and mental retardation.
