Effect of horse riding equipment in activity of trunk and lower limb muscles in equine-assisted therapy

Equine-assisted therapy uses the horse in rehabilitation and/or education of people, such as Down syndrome(SD), cerebral palsy(PC)and intellectual disability(DI). In context, the rehabilitation program and horse riding equipment should be usedaccording to the specific characteristics of each individual, becoming an ally in the quest for excellence in equine-assisted therapy programs. The aim was to evaluate the effect of riding equipment used in equine-assisted therapy on the muscular activityof trunk and lower limb of individuals with SD, PC and DI. The study included 15 individuals equally assigned to each group: SD, PC and DIwith a mean age of 16.2 (±1.10), 16 (±1.22)e 16 (±0) years,respectively. The analysis of muscle activity was performed through surface electromyography, using four variations of horse riding equipment: saddle with and without feet supported on the stirrups and blanket with and without feet supported on the stirrups. Sigma Stat 3.5®software was used for statistical analysis.The Shapiro Wilk's test was used for normality of the data, the Bartlett test for homogeneity of the variances and the Kruskal-Wallis test for repeated measures with no normal distribution.Statistically significant differences were observed forp<0.05.The SDgroup presented a greater muscular activity of trunk and lower limbs with blanket equipment without the feet supported in the stirrups (H = 15.078, p = 0.002), as in the DI group (H=8.302, p = 0.040), while inPCgroup was the saddle with feet supported in the stirrups (H=11.137,p = 0.011). The choice of riding equipment used in equine-assisted therapy interferes differently in the pattern of muscular activation of the trunk and the lower limbs, according to the pathological processes of the practitioners. It should be an important aspect to consider when planninga treatment.

Material de montaria para equoterapia em indivíduos com síndrome de Down: estudo eletromiográfico / Riding equipment for hippotherapy in individuals with Down syndrome: an electromyographic study

Introdução: Os indivíduos com síndrome de Down apresentam características peculiares da anomalia, sendo a principal e mais frequente a hipotonia muscular. Objetivo: Verificar o melhor material de montaria e posicionamento dos pés para o recrutamento da musculatura de tronco de crianças com síndrome de Down que utilizam do tratamento da equoterapia. Métodos: Foram avaliados cinco praticantes com síndrome de Down por meio da eletromiografia, durante quatro sessões de equoterapia. Para análise estatística, foi utilizado o teste de Kruskal- Wallis para comparações múltiplas de dados não paramétricos. Resultados: O material de montaria de manta associado com os pés fora do estribo proporcionou maior recrutamento dos músculos estudados, sendo o músculo da região cervical o mais acionado. Conclusão: Por meio desse estudo piloto, infere-se que a manta com pés fora do estribo promoveu uma melhor otimização do tônus dos indivíduos analisados.

Introduction: Individuals with Down syndrome have peculiar characteristics of the anomaly, the main and most common is muscle hypotonia. Objective: To check the best material to mount and position the feet for the recruitment of the trunk muscles of children with Down syndrome using the treatment of hippotherapy. Methods: Five riders with DS were assessed using surface electromyography during four sessions of therapeutic riding. Statistic analysis: data were analyzed using the Kruskal-Wallis non parametric test. Results: The material riding blanket associated with the feet out of the stirrup elicited greater recruitment of the muscles being studied, the muscle of the cervical region being triggered the most. Conclusion: Through this pilot study we infer that the blanket with feet out of the stirrup promoted a better optimization of the tone of the individuals included in the study.

Therapeutic effects of a horse riding simulator in children with cerebral palsy / Efeitos terapêuticos de um simulador de equitação em crianças portadoras de paralisia cerebral

OBJECTIVE: To evaluate the efficacy of horse ridding simulator on the sitting postural control of children with spastic diplegia. METHOD: Forty children were randomly divided in a group using the simulator (RS) and a group performing conventional physical therapy (CT). FScan/Fmat equipment was used to register maximal displacement in antero-posterior (AP) and medio-lateral (ML) directions with children in sitting position. At the pre and post intervention stage both groups were classified according to the Gross Motor Function Classification System (GMFCS) and, after intervention, by the AUQEI questionnaire (Autoquestionnaire Qualité de vie Enfant Image). RESULTS: Comparison between groups disclosed statistically significant pos-intervention improvement both in the AP (p<0.0001) as in the ML (p<0.0069) direction in the RS group. CONCLUSION: The horse ridding simulator produced significant improvement in the postural control of children in sitting position, additionally showing a higher motor functionality and a better acceptance of the therapeutic intervention.

OBJETIVO: Avaliar os efeitos terapêuticos de um simulador de equitação no controle postural sentado de crianças portadoras de diplegia espástica. MÉTODO: Quarenta crianças foram aleatoriamente divididas em dois grupos: 20 utilizaram o simulador (GS) e 20 realizaram fisioterapia convencional (TC). Foi efetuado o registro dos deslocamentos máximos na direção ântero-posterior (AP) e médio-lateral (ML) com a criança sentada, utilizando-se o sistema FScan/Fmat. Antes e após intervenção as crianças foram classificadas pelo Gross Motor Function Classification System (GMFCS) e, após intervenção, pelo AUQEI (Autoquestionnaire Qualité de vie Enfant Image). RESULTADOS: Melhora estatisticamente significativa dos deslocamentos máximos foi observada após intervenção tanto na direção AP (p<0,0001) quanto na ML (p<0,0069) no grupo GS quando comparado ao grupo TC. CONCLUSÃO: O simulador de equitação produziu melhora significativamente maior no controle postural da criança sentada, aliada a maior funcionalidade motora e melhor aceitação da intervenção terapêutica.
