Brief Summary

Introduction: Autism Spectrum Disorder (ASD) is characterized as a neurodevelopmental disorder, with motor symptoms that may predispose to falls and gait changes. Exercises through virtual reality (exergaming) showed good results in children with ASD, but no studies were found that evaluated the effects of exergaming on gait and the risk of falls. Objective: To evaluate the effects of exergaming on motor performance during gait and the risk of falls in children with ASD. Method: Pilot study of a clinical trial. There will be 22 participants, diagnosed with ASD, level I or II; age: 5 to 9 years old; that they do not use medications that interfere with postural balance and falls; without physiotherapy care for at least 2 months. They will be divided into Exergaming Group (EG, n=11) and Control Group (GC, n=11). The GC will receive guidance through booklets. The EG will be submitted to a treatment with exergaming for 3 months, with 2 weekly sessions of 45 min each (initial 10 min, 25-30 of exergaming with the Xbox360 console with Kinect sensor and game "Kinect Adventures!", 5 min of cool down ). They will be assessed using CARS-BR (Childhood Autism Rating Scale - Brazilian version), DCDQ (Developmental Coordination Disorder Questionnaire), EEP (Pediatric Equilibrium Scale), a semi-structured questionnaire to assess the history of falls and prevalence of falls, an adapted motivational scale for ASD, a satisfaction survey, and three-dimensional assessment of gait through the Gait Laboratory. Descriptive analysis will be performed and continuous variables will be summarized in mean and standard deviation, and categorical variables in absolute and relative frequencies. To compare the independent and paired variables, parametric tests will be used and a significance level of 5% will be considered (p <0.05). Pearson's correlation will be used to assess correlations between continuous variables and the Chi square test to assess the relationship between categorical variables. Expected results: It is expected that children from the EG will obtain better results than the CG on gait variables and the risk of falling, with clinical and statistical significance.

Detailed Description

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder with altered motor aspects, present among 50-88% of children with ASD1. They can present difficulties in motor planning, altered gait, postural imbalance, and decreasing postural control, thus increasing the risk of falls.

Children with ASD have variability in gait patterns intra-individually, considering stride length, stride time, and walking speed5. The gait kinematic alteration includes wider step width, decrease in gait velocity, increase in stance time, gait cycle and step time, and differences in cadence and gait cycle compared to children without ASD5. A study showed that children with ASD have a more severely impaired postural balance than other neurodevelopmental disorders and typical children.

The impaired gait patterns can lead to pain, fatigue, and joint stress, affecting the functional capacity of children with ASD and impacting their quality of life. Also, it has been suggested that the motor alterations present in children with ASD are related to difficulties in communication and socialization, difficulties in the development of cognitive abilities, contribute to adaptative dysfunction, decrease the physical functional capacity, and increase the chance of obesity. The motor abilities are strongly related to adaptative function and quality of life of children with ASD, anticipating the deficits in social communication.

Although there is evidence in the literature concerning motor difficulties in children with ASD, it is estimated that 1,34% of them are diagnosed with motor alteration. Besides, it is an underestimated diagnostic among physical therapists in clinical practice. This highlights the importance of functional diagnostics and the study of possible interventions that can be useful in clinical practice in treating motor alterations, especially gait, and the risk of falls.

Exergaming (EXG) has been used as a treatment in children with ASD, demonstrating positive results. Among the effects of EXG in children with ASD are an improvement in explosive strength, better performance in velocity and agility, improvement of aerobic capacity, better work memory capacity, better strength and agility, improved perception of competence, reduced stereotypical behaviors, improved measurement of executive function, reduced aimless arm movements, and decreased body mass index.

Thus, EXG is a valuable tool to treat children with ASD. However, few studies have used EXG to treat motor aspects, especially those related to gait or balance performance. This highlights the following question: Could EXG improve the gait and lessen the risk of falls in children with ASD? Therefore, the primary objective of this study is to describe a randomized and controlled clinical trial protocol to verify the effect of EXG on gait and risk of falls in children with ASD. The secondary objective is to describe the gait measurement and the risk of falls to assess the effect of exergaming in children with ASD. The hypothesis is that the EXG will lessen gait alterations in children with ASD and improve postural balance, lessening the risk of falls.

Study Groups

Exergaming Group (EG)

The EG will participate in the intervention protocol with exergaming and will also receive the guidance booklet at the end of the treatment. Protocol: twice a week, with a total duration of 40-45 minutes each, conducted by a single physiotherapist. The initial 10 minutes will be for reception, accommodation/heating and anticipation of the service. The Exergaming will last 25-30 minutes, observing the children's reactions to the dosage of the game and the manual and verbal interventions of the physiotherapist. The final 5 minutes will be for cooling down (relaxing music).

The video game will be the Xbox 360 with a Kinect TM sensor , which captures body movement during the game. The game will be "Kinect Adventures!", and minigames: "peak of reflections" and "20,000 leaks". During the game, the physiotherapist will stimulate the child's proprioception in order to promote sensory and verbal feedback. The intervention will last 12 weeks, with 2 weekly sessions, totaling 24 sessions.

Group Type: EXPERIMENTAL

Exergaming

Intervention Type: OTHER

Use of the exergame XboX 360 series with kinect sensor

Control Group (CG)

The CG will be formed by participants admitted to the institution and who are on the waiting list for physiotherapy care and will follow the guidelines of the physiotherapy booklet with recommendations for physical activities that encourage the child's usual mobility, such as: moments of play with the family, walks outdoors and encourage varied ludic motor experiences. This booklet will be created by the researcher and will not change the routine of the service. The CG will be telemonitored biweekly via messaging application by the researcher, through a personal telephone, with a proposal to check the progress of the application of the booklet, clarify doubts with the family and monitor the child. This telemonitoring protocol was established exclusively for the research.

Group Type: ACTIVE_COMPARATOR
