The Translation of Movement From the Equine to Rider With Relevance for Hippotherapy

Abstract

Although horseback riding is a well-established means of rehabilitation therapy for a variety of human patients, there are few data on the biomechanical relationships between horse and rider during such hippotherapy. We simultaneously tracked the movements of a horse with several different novice riders, under conditions similar to hippotherapy, to evaluate whether horses pass the same motion to different riders while being lead at a walk. Riders were outfitted with a goniometric data collection system that recorded the angles of flexion and extension and lateral bending of the thoracic and lumbar spine, as well as the flexion, extension, abduction, and adduction of each hip. We found consistent rhythmic motion in the horse's hock, shoulder, and knee. There were no significant differences in equine movement across six different riders, supporting the conclusion that horses can be used as a reproducible rehabilitation platform for riders. Moreover, although riders demonstrated different baseline postures, there were no significant differences in their ranges of motion in each joint. These results indicate that a horse can reproducibly influence a population of participants in a hippotherapy situation.
