Effects of Hippotherapy on Health-Related Quality of Life in Caregivers of Children with Cerebral Palsy: A Pilot Quasi-Experimental Study in Japan.

Abstract

Despite accumulating data regarding the beneficial effects of hippotherapy on gait and balance skills in children with cerebral palsy (CP), its effects on caregivers' quality of life (QOL) are limited, presumably due to a lack of reliable and valid measurement tools. This study aims to evaluate the impact of hippotherapy on the health-related QOL of primary caregivers using the Japanese version of the Cerebral Palsy Quality of Life for Children (CP QOL) questionnaire. A quasi-experimental design embedded within our existing cohort was utilized. A total of 29 children with CP (range 4-12 years) and their caregivers participated in either a weekly hippotherapy or recreation (usual care) program for 1 year. In addition to gait-related measurements (Gross Motor Function Measure [GMFM]-E) of children, CP QOL-evidenced determinants of the caregivers' health-related QOL and well-being were compared before and after the intervention. In addition to improvements in children's GMFM-E scores, hippotherapy improved CP QOL domains related to participation and physical health, children's emotional well-being, and parents' overall health (p < 0.05). Linear regression analysis showed a positive relationship between the children's GMFM-E scores and their caregivers' health domains in participants who received hippotherapy (r2 = 0.404; p = 0.011). Hippotherapy has a beneficial effect on the physical and mental well-being and satisfaction of Japanese parents caring for children with CP.
