Animal assisted therapy in pediatric mental health conditions: A review

Animal assisted therapy (AAT) has been explored as a treatment option for children with mental health disorders and associated symptoms. AAT can be implemented in inpatient, outpatient, and residential care settings. Some studies demonstrate significant improvement in symptom severity while others report only modest results. In this review, we summarize previous studies that have investigated the applications of AAT for pediatric mental health treatment, focusing on management of symptoms related to post-traumatic stress disorder, depression, anxiety, attention-deficit/hyperactivity disorder, and internet gaming disorder. Current studies on AAT and mental health care tend to lack generalizability due to being single-site studies, and comparisons between studies are difficult because studies tend to adopt different definitions of AAT. Future studies examining the effects of AAT on mental health in general and on symptoms for specific conditions are needed before AAT is widely recommended for the pediatric population.

Biomechanical comparison of human trunk and thigh muscle activity during walking and horseback riding activity

INTRODUCTION

Hippotherapy is a physical therapy tool that utilizes horseback riding to improve strength, coordination, gait, and balance. These benefits may be linked to similarities in kinematics and muscle activation between horseback riding and normal human gait, but this is not well represented in the literature, especially for muscle activation. The purpose of this study was to investigate the relationships between muscle activation of horseback riding and healthy human gait.

METHODS

The muscle activation of nine healthy female participants (age 18-22) were recorded during walking and horseback riding trials using surface electromyography (EMG). Muscles analyzed include rectus abdominis, lumbar erector spinae, rectus femoris and biceps femoris. Activation waveforms during walking and riding were generated, and from this average and maximum contraction magnitudes were recorded.

RESULTS

Average muscle activation was significantly greater in riding for the left (p = 0.008) and right (p = 0.04) biceps femoris. Additionally, average and maximal activation of the left erector spinae were significantly greater in riding (W = 4; critical value for W at n = 9 is 5). Remaining differences in muscle activation between walking and riding were non-significant.

DISCUSSION

Peak and average muscle activation magnitude across the gait cycle were similar for most muscle groups. When present, differences were greater in riding. Despite these similarities, EMG waveforms displayed more predictable temporal patterns in walking.

CONCLUSION

These findings suggest that hippotherapy could be used to elicit muscle excitation similar to that of normal gait, which may have promising implications for rehabilitation targeting gait correction.

Equine assisted services impact on social skills in autism spectrum disorder: A meta-analysis

Many studies focus on the impact of equine assisted services (EAS) on social skills in autism spectrum disorder (ASD) but existing data are not consensual and the only available meta-analysis included only three studies and did not consider the social responsiveness scale (SRS). This meta-analysis aims to measure the impact of EAS on social skills in ASD. Using Pubmed, Embase, Web of Science and the Cochrane Library, the means and standard deviations of every available SRS post-intervention scores in each participant group were collected from the five selected randomised controlled trials with 240 participants. An EAS significant beneficial impact was found for the total SRS score, social communication and social cognition. A tendency to a significant impact was found for social awareness and social motivation. No significant difference was shown for autistic mannerisms. This meta-analysis shows a significant beneficial impact of EAS for several social skills in ASD. Further randomised controlled trials are required to complement these results and expand the knowledge on the field of possibilities of this care in ASD.

Physical therapy treatments incorporating equine movement: a pilot study exploring interactions between children with cerebral palsy and the horse

BACKGROUND

Physical therapy treatments incorporating equine movement are recognized as an effective tool to treat functional mobility and balance in children with cerebral palsy (CP). To date, only a few studies examined kinematic outputs of the horses and children when mounted. In this pilot study, to better understand the effectiveness of this type of treatment, we examined the interaction between the horses and children with CP during physical therapy sessions where equine movement was utilized.

METHODS

Four children with CP participated in eight physical therapy sessions incorporating hippotherapy as a treatment intervention. Functional mobility was assessed using the Timed Up Go or the 10 m Walk Test. Inertial measurement unit sensors, attached to children and horses, recorded movements and tracked acceleration, angular velocity, and body orientation. Correlation between vertical accelerations of children and horses were analyzed. In addition, peak frequencies of vertical accelerations of children and horses were compared.

RESULTS

Functional tests modestly improved over time. The children's movements, (quantified in frequency and temporal domains) increasingly synchronized to the vertical movement of the horse's walk, demonstrated by reduced frequency errors and increased correlation.

CONCLUSIONS

The findings suggest that as the sessions progressed, the participants appeared to become more familiar with the horse's movement. Since the horse's gait at a walk mimics the human gait this type of treatment may provide individuals with CP, who have abnormal gait patterns, an opportunity for their neuromuscular system to experience a typical gait pattern. The horse's movement at the walk are consistent, cyclical, rhythmical, reciprocal and multi-dimensional, all of which can facilitate motor learning. The increased synchronization between horse and the mounted participant suggests that physical therapy utilizing equine movement is a viable treatment tool to enhance functional mobility. This study may provide a useful baseline for future work. Trial registrationTexas A&M University Institutional Review Board. IRB2018-0064. Registered 8 March 2018.
