简要总结
The prevalence of autism spectrum disorders (ASD) has increased dramatically in the last decade. The increasing occurrence of ASD creates an imperative need to test the effectiveness and efficacy mechanisms of appropriate interventions. Hippotherapy (HPOT) is a treatment option that has been show beneficial for children with ASD as well as other children with developmental disorders. The current projects focuses on understanding the mechanisms of HPOT efficacy and evaluating a short-term HPOT program for children with ASD.
详细描述
The incidence of autism spectrum disorders (ASD) has increased dramatically in the last decade. The latest report from the Centers for Disease Control and Prevention state that 1 in 59 children are being diagnosed with ASD and it is four times more prevalent in boys than girls. Common treatments for children with ASD are applied behavioral therapy, occupational and speech therapy, which are used solely or in combination. Hippotherapy (HPOT) is another treatment option that has been shown to positively impact various aspects of behavior. This pilot project aims to determine the effects of a 6-week HPOT program on movement and social behavior of children with ASD and to investigate the underlying mechanisms of why HPOT is successful for ASD through the coupling of physiological and temperamental responses between horse and rider. The approach involves examining these skills pre, during, and post HPOT intervention in children diagnosed with ASD. A group of aged matched children with typical development will serve as the control group. Innovative measures of physiological coupling and temperament between horse and rider as well as objective and quantitative measures of movement and social behavior and caregiver perception will be collected. The investigators anticipate that following completion of the proposed study, they will provide the necessary foundation to understand the mechanisms of HPOT, and thus provide a new framework to test clinical trials of HPOT and human-animal interaction, and ultimately improve the lives of those diagnosed with ASD and their families.

结局指标
主要结局
Postural Control
时间窗: Change from Pre (baseline) to Post (6 weeks after hippotherapy intervention)
Postural control assessment with a force platform with eyes open and eyes closed. Differences were more prevalent with eyes closed. We report a specific measure of postural control which is median frequency while standing with eyes closed. Median frequency can have a very wide range of values, but increased values of median frequency suggest faster postural control adaptations.
Cross Sample Entropy Between the Heart Rate Sensors of the Horse and Rider
时间窗: During week 1, week 3 and week 6 of the treatment sessions
Heart rate monitors were placed around the upper thorax of both the rider and horse and simultaneously began collecting data at the beginning of each session. Data was collected at the first, third, and sixth sessions of the intervention. We used the heart rate signals of the horse and rider to calculate the Cross approximate entropy. Cross-ApEn quantifies the regularity of patterns in a pair of related time series and is indicative of the dimensionality of control of the two signals. The calculation of Cross-ApEn is similar to approximate entropy with the exception that successive two-point vectors of one signal are compared with current and previous two-point vectors of another signal. Larger Cross-ApEn values indicate greater joint signal asynchrony while lower Cross-ApEn values indicate greater joint signal synchrony.For details on calculation of Cross-ApEn please refer to: Pincus S, Singer BH. Randomness and degrees of irregularity. Proc Natl Acad Sci USA. 1996; 93: 2083-2088.
Social Responsiveness Scale (SRS)
时间窗: Change from Pre (baseline) to Post (after completion of 6 weeks of intervention)
The SRS provides a clear picture of a child's social impairments, assessing social awareness, social information processing, capacity for reciprocal social communication, social anxiety/avoidance, and autistic preoccupations and traits. The SRS is a 65-item rating scale that measures autism traits over the previous 6 months in children and adolescents aged 4-18 years. Each item is scaled from 0 (never true) to 3 (almost always true), generating a total score ranging from 0 to 195.The total score of the SRS is reported below. Higher values represent worse outcome.
