et al., 2012, p. 151). The study relied on 3-D videography to track the motion of several horses carrying various riders representative of hippotherapy patients over the course of one hippotherapy session (Janura, M. et al., 2012, p. 148). The study concluded that there was no statistically significant variation in motion during the sessions, and that the horses' motion was consistent while walking during a single session (Janura, M. et al., 2012, p. 151). This study does not account for variation of movement caused by varying leaders of hippotherapy sessions; it merely accounts for the horse
