Effect of hippotherapy on gait symmetry in children with cerebral palsy: A pilot study

: We aimed to investigate the effect of hippotherapy on gait symmetry in children with cerebral palsy (CP). Twelve children with Gross Motor Function Classification System (GMFCS) levels II-IV received weekly hippotherapy lesson for 1 year. Gait analyses were performed during a 5-m walking test, using a portable, tri-axial accelerometer-based motion recorder. The baseline symmetry index derived from the Lissajous index (LI) figure before hippotherapy was greater than the LI in age-matched normal subjects (P < 0.01). Hippotherapy was associated with a decreased LI (-10.4 ± 4.9%, P = 0.018) and an improved GMFCS score (-0.6 ± 0.7, P = 0.02). These data suggest that hippotherapy has a beneficial effect on symmetry of the trunk movement in children with CP.
