“…The observation that participants with ASD performed worse in the environment without physical contact when compared to the physical contact environment can be interpreted considering the "speed and accuracy" trade-off, which proposes that the more difficult the task, the higher the time to complete it (i.e., worse performance during practice). Similar findings have been consistently reported in people with disabilities during a virtual task [Fernani et al, 2017;Robert & Levin, 2018;Stevens, Anderson, O'Dwyer, & Mark Williams, 2012]. However, this difficulty in the VR task promoted performance gains, with better execution in the following real task in people with ASD, as demonstrated by the results of both sequences.…”

Autism spectrum disorder (ASD) is associated with persistent deficits in social communication and social interaction, including impaired multisensory integration, which might negatively impact cognitive and motor skill performance, and hence negatively affect learning of tasks. Considering that tasks in virtual environment may provide an engaging tool as adjuncts to conventional therapies, we set out to compare motor performance between young people with ASD and a typically developing (TD) control group that underwent coincident timing tasks based on Kinect (no physical contact) and on Keyboard (with physical contact) environments. Using a randomized repeated cross‐over controlled trial design, 50 young people with ASD and 50 with TD, matched by age and sex were divided into subgroups of 25 people that performed the two first phases of the study (acquisition and retention) on the same device—real or virtual—and then switched to the other device to repeat acquisition and retention phases and finally switched on to a touch screen (transfer phase). Results showed that practice in the virtual task was more difficult (producing more errors), but led to a better performance in the subsequent practice in the real task, with more pronounced improvement in the ASD as compared to the TD group. It can be concluded that the ASD group managed to transfer the practice from a virtual to a real environment, indicating that virtual methods may enhance learning of motor and cognitive skills. A need for further exploration of its effect across a number of tasks and activities is warranted.

Lay Summary Individuals with autism spectrum disorder are known to have difficulties with learning motor tasks. Considering that performing motor tasks in virtual environment may be an engaging tool as adjuncts to conventional therapies, we aimed to estimate performance in tasks regardless of physical touch. Results showed that participants had more difficulty using the non‐touch task; however, virtual training improved performance on the physical (real) task. This result indicates that virtual methods could be a promising therapeutic approach for the ASD population.

“…During the concrete task, the individuals with CP would have had to significantly control their preferred hand to touch the computer screen, which requires accuracy with more adequate acceleration and deceleration of movement. As cited by Fernani et al [20], individuals with CP presented greater difficulty when performing tasks that require more precision of movement rather than velocity. Thus, based on our results, the concrete task requires more precision and fine movement, while abstract tasks have the characteristic of speed with global movements.…”

“…However, real tasks generally require fine control of functions, and hence, a greater accuracy of movement to touch an object. Due to alteration in muscle coordination and co-contraction, individuals with CP present more difficulty in performing such functions accurately [20].…”

Background: Cerebral Palsy (CP) is characterised by variable difficulties in muscular action, resulting in inability of the individual to perform functional movement. An option to provide functionality to the individual with CP is the use of computer innovation. The aim of this paper was to verify if there was any performance improvement in a task performed in a virtual environment and if there was transfer to the task performed in the real environment and vice versa in this population. Methods: A computer program was developed comprising a motor task, but with two possibilities of user interaction: a) concrete interface (with physical contact): in which the individual touches the computer screen to finish the task and b) abstract interface (no physical contact): in which the individual performs a hand movement in front of the Kinect device. Participants were split into two groups. The experimental group consisted of 28 individuals with CP within the ages of 6 and 15 years old. The control group included 28 typically developing individuals mirroring the age and sex of the experimental group. Results: Individuals from both groups were able to improve task performance and retain acquired information. The CP group presented worse performance than the control group in all phases of the study. Further findings showed that the CP group presented better performance in the abstract interface than in the concrete interface, whereas, in the control group, the opposite occurred: their best performance was in the concrete.

Objective: To analyze the psychomotor development and the fine motor control of institutionalized and non-institutionalized sheltered children and adolescents. Methods: A cross-sectional study in which 54 subjects participated and were divided into two groups: 27 institutionalized sheltered children and adolescents (SG) and 27 non-institutionalized sheltered children and adolescents (CG). The psychomotor battery and the Learning and Motor Control software were used to evaluate development and motor control. The analysis of variance was performed for both groups with repetitive measurements for the last factor. Results: The SG presented a total development score inferior to the CG, with differences in tonicity (p=0.041) and body awareness (p=0.039). The longest distance was performed on Task 1 (M=983.9 pixels; diagonal line; distance of 930.053 pixels), with no difference between the groups (p=0.64). Furthermore, the SG presented a greater average time in Task 1 (M=16.12 seconds) when compared with Tasks 2 (M=11.6 seconds; horizontal line; distance of 750 pixels) and 3 (M=10.6; vertical line; distance of 550 pixels), but only marginally different between Tasks 2 and 3 (p=0.055). Regarding the number of correct answers, the CG scored more (M=6.1) when compared with SG (M=4.6), with p<0.05. Conclusions: The institutionalized individuals showed a psychomotor development inferior to the CG. Furthermore, they presented impairment in fine motor control, covering a larger distance on the task that required the diagonal movement, longer execution time, less correct answers, and more errors.
