Abstract
Background
Hippotherapy is a complementary therapeutic modality that seeks to promote functional changes in children with cerebral palsy (CP). Knowledge of the direct and indirect changes resulting from this therapy will help identify which groups of children with cerebral palsy can benefit from this type of therapy. The present study aimed to analyze the effects of hippotherapy for children with cerebral palsy with regard to age, topography, and severity using the rehabilitation treatment taxonomy.
Methods
We conducted a before-after clinical trial. Thirty-one children with CP, stratified by age (4-7 years; 8-12 years), severity (mild, moderate, severe), topography (hemiplegia, diplegia, quadriplegia) and previous time in hippotherapy (3-6 months, over 6 months) underwent individual weekly 30-minute hippotherapy sessions for 6 months in addition to regular rehabilitation. Postural control and balance were evaluated by the Early Clinical Assessment of Balance (ECAB). Secondary outcome measures included the Gross Motor Function Measure (GMFM) and the Cerebral Palsy Quality of Life for Children self-report of the primary caregiver questionnaire. Blinding was used for scoring the outcome measures.
Results
Postural control and balance and gross motor function showed small improvements after 6 months of intervention, with larger effects in dimensions D and E of the children’s gross motor function. These changes were influenced by the severity and topography of the CP. The taxonomy of rehabilitation treatments structured the interpretation of the hippotherapy effects, identifying the possible mechanism of action (horse’s step and movement demands), active ingredients (activation of muscles involved in postural correction, vestibular and visual stimuli), target outcomes (postural control and balance) and indirect outcomes (gross motor function and quality of life).
Conclusion
Hippotherapy sessions, in addition to rehabilitation, produced small, but positive changes in motor and psychosocial outcomes in children with CP. The benefits varied from 3 to 7 points in postural control and balance (ECAB) and in all dimensions of the GMFM. The changes in gross motor function were influenced by the type and severity of CP.
