Thérapie par l'équitation pour une personne sourde-aveugle activée par une interface haptique

Aperçu: G.M.
L'étude présente une interface haptique pour aider les sourds-aveugles à pratiquer l'équitation comme activité récréative et thérapeutique.
es réponses aux questionnaires remplis par le cavalier, la famille et l'instructeur montrent que notre technique donne au coureur un plus grand sens de l'indépendance et plus de joie par rapport à l'équitation standard où l'instructeur marche avec le cheval.

Abstract

We present a haptic interface to help deafblind people to practice horseback riding as a recreational and therapeutic activity. Horseback riding is a form of therapy which can improve self-esteem and sensation of independence. It has been shown to benefit people with various medical conditions-including autism. However, in the case of deafblind riders, an interpreter must stand by at all times to communicate with the rider by touch. We developed a simple interface that enables deafblind people to enjoy horseback riding while the instructor is remotely providing cues, which improves their independence. Experiments demonstrated that an autistic deafblind individual exhibits similar responses to navigational cues as an unimpaired rider. Motivation is an important factor in therapy, and is frequently determinant of its outcome; therefore, the user attitude toward the therapy methods is key. The answers to questionnaires filled by the rider, family, and the instructor show that our technique gives the rider a greater sense of independence and more joy compared to standard riding where the instructor is walking along with the horse.

La variabilité accrue de la force est associée à une modification de la modulation de l'activité de l'activité d'ensemble de motoneurones dans le trouble du spectre de l'autisme

Aperçu: G.M.
Les déficits de contrôle de la force ont été documentés à plusieurs reprises dans le trouble du spectre de l'autisme (TSA). Ils sont associés à une plus grande détérioration des habiletés sociales et de la vie quotidienne chez les personnes, ce qui suggère que développer une compréhension plus mécanique des processus centraux et périphériques qui les causent peut aider à guider le développement de traitements qui améliorent les résultats multiples dans le TSA.
Les personnes avec un diagnostic de TSA présentaient une plus grande variabilité de force que les témoins lorsqu'ils essayaient de maintenir une force constante. Ces résultats suggèrent que des altérations des mécanismes centraux qui contrôlent le déclenchement d'ensembles de motoneurones peuvent sous-tendre les symptômes communs et souvent invalidants des TSA.

Abstract

Force control deficits have been repeatedly documented in autism spectrum disorder (ASD). They are associated with worse social and daily living skill impairments in patients suggesting that developing a more mechanistic understanding of the central and peripheral processes that cause them may help guide the development of treatments that improve multiple outcomes in ASD. The neuromuscular mechanisms underlying force control deficits are not yet understood. Seventeen individuals with ASD and 14 matched healthy controls completed an isometric index finger abduction test at 60% of their maximum voluntary contraction (MVC) during recording of the first dorsal interosseous (FDI) muscle to determine the neuromuscular processes associated with sustained force variability. Central modulation of the motorneuron pool activation of the FDI muscle was evaluated at delta (0-4 Hz), alpha (4-10 Hz), beta (10-35 Hz) and gamma (35-60 Hz) frequency bands. ASD patients showed greater force variability than controls when attempting to maintain a constant force. Relative to controls, patients also showed increased central modulation of the motorneuron pool at beta and gamma bands. For controls, reduced force variability was associated with reduced delta frequency modulation of the motorneuron pool activity of the FDI muscle and increased modulation at beta and gamma bands. In contrast, delta, beta, and gamma frequency oscillations were not associated with force variability in ASD. These findings suggest that alterations of central mechanisms that control motorneuron pool firing may underlie the common and often impairing symptoms of ASD.

A travers l'optique kinesthésique: Observation de l'inadéquation sociale dans les troubles du spectre de l'autisme


Aperçu: G.M.  
La thérapie de mouvement de danse (DMT) est une intervention psychothérapeutique qui est utilisée avec les participants avec ASD dans divers environnements. une étude systématique du développement des comportements de syntonie sociale des participants avec un diagnostic de TSA tout au long d'une intervention DMT n'était pas encore disponible.
Une perspective axée sur le mouvement peut être utile pour inventorier les changements dans les comportements d'harmonisation sociale chez les participants.

Abstract

This paper will present a movement-informed perspective to social attunement in Autism Spectrum Disorders (ASD).

BACKGROUND:

Dance movement therapy (DMT) is a psychotherapeutic intervention that is used with participants with ASD in various settings. Regular clinical outcome monitoring in an outpatient setting in the Netherlands had shown positive effects on social attunement capacities in young people with ASD. However, a systematic study of the development of social attunement movement behaviors of participants with ASD throughout a DMT intervention was not yet available.

METHODS:

A series of individual cases of DMT with young people with ASD (mean age 12.2 years.) were analyzed for changes in interpersonal movement behaviors employing video-based retrospective observation.

RESULTS:

The findings were summarized in an observation scale for interpersonal movement behaviors. This scale was then tested for its applicability for the monitoring of social attunement behaviors throughout therapy.

DISCUSSION:

A movement-informed perspective may be helpful to inventory changes in social attunement behaviors in participants with ASD. The relevance of a movement-informed perspective for the concept of social attunement in ASD will be discussed.
