About

The purpose of this pilot study is to determine whether a video-game based motor training can affect postural stability, daily living skills, autism symptoms, and white matter microstructure of the corticospinal tract in adolescents with Autism Spectrum Disorder (ASD).

Full description

Participants: Participants will include 30 adolescents with ASD (13-17 years of age) and 30 adolescents with typical development. Exclusion criteria consists of engaging in more than 2 hours/week of balance training activities (i.e., yoga, tai chi, Wii/Kinect balance games) at study start. Each individual will receive a pre-training magnetic resonance imaging (MRI) scan. Participants will be randomly assigned to either a treatment group or control group. Over the next six weeks, participants in the treatment group will come to the lab to complete 3-5 hours/week of video-game motor training. Participants in the passive control group will come to the lab to do basic motor measurements and sedentary video gaming without motor training. Participants will be asked not to start any new exercise-related programs during those 6 weeks. After the sixth week, all participants will complete a post-training MRI scan and behavioral assessment.

Motor Video Game Training: Participants in the treatment group will come to the University of Wisconsin lab to train 3-5 days each week under research staff supervision. Each training session will last 30-60 minutes and will begin and end with ~5 minutes playing the Ninja Training game from Dr. Ellertson's lab (Boise State University). In this game, participants will hold a position (i.e., the Karate Kid crane pose) for as long as they can, while we collect time-series data on the position of each joint using the Kinect camera as well as time-series data on the center of pressure using the Wii balance board. Participants are rewarded for holding the pose as long as possible by seeing the background behind them come to life. For the rest of the training, participants will play balance games from the Wii Fit.

Motor & Symptom Severity Assessments: Pre-post postural stability measures will be assessed in both groups through standing postures on the Wii balance board (as in Travers et al., 2013). Pre-post symptom severity measures will include parent-report measures of social function, repetitive behaviors/restricted interests, and measures of daily living skills.

Imaging Protocol: Pre- and post-training brain imaging will be completed using a 3 Tesla (ET) MRI scanner with a Nova 32-Channel Head Coil. All scanning will be performed in <60 minutes. Pulse sequences and protocols include advanced diffusion weighted imaging (DWI) with NODDI (Zhang et al., 2012) and multicomponent T1 and T2 relaxometry using steady state sequences (mcDESPOT; Deoni et al., 2008; Alexander et al., 2011). Structural imaging of anatomical detail for morphometric analyses will also be performed using a custom MP2RAGE sequence, which inherently removes the intensity variations from inhomogeneities in the coil sensitivities.

62 participants in 2 patient groups

Video Game Motor Training

Experimental group

Description:

Participants in the treatment group will come to the University of Wisconsin lab for six weeks to train 3-5 days each week under research staff supervision. Each training session will last 30-60 minutes and will include playing our in-house Ninja Training game combined with balance games from the Wii Fit.

Treatment:

Behavioral: Video Game Motor Training

Sedentary Video Game Training

Active Comparator group

Description:

Participants randomly assigned to this condition will come to the lab for six weeks to play sedentary video games 3-5 days each week under research staff supervision. Each training session will last 30-60 minutes. Pre-and post assessments will be done identically to the Experimental group.

Treatment:

Behavioral: Sedentary Video Game Training
