Restricted and repetitive behaviors (RRBs) and executive dysfunction are widely acknowledged as core features and hallmarks in patients with autism spectrum disorder (ASD). This study aimed to investigate the effects of augmented reality (AR) using motivational games with cognitive–motor exercises on RRBs, executive function (EF), attention, and reaction time in patients with ASD. Twenty-four patients (range from 6 to 18 years) diagnosed with ASD were recruited from local social welfare centers and randomly allocated to the AR game-based cognitive–motor training group (study group) or the conventional cognitive training group (control group). Both groups completed 30 min training sessions, twice a week for four weeks. Outcome measures were conducted before and after the intervention. As a result, improvements were observed in all the subscales of the RRBs in the study group except for self-injurious and ritualistic behavior. Significant improvements were observed in EF and reaction time in the study group, which was significantly higher compared to the control group. With the present findings, we can suggest that cognitive–motor training using AR game-based content generates positive effects on improving executive function reaction time and accuracy of responses and has a limited effect on RRBs in patients with ASD. This can be proposed as a complementary intervention associated with individualized daily management.

The COVID‐19 pandemic had a global impact, increasing the prevalence of physical inactivity, which is mostly due to the lockdown and social distancing measures adopted during the pandemic. Hence, this study aimed to compare the efficacy of augmented reality‐based training on physical activity performance and motivation in healthy adults to mirror visual feedback training and conventional physical therapy. This study used the randomized control trial pretest‐posttest research design. Forty‐eight healthy men aged 18–35 years who were engaged in recreational physical activities were enrolled and randomly divided into four groups: augmented reality‐based training reality (ART), mirror visual feedback training (MVFT), therapist‐based training (TBT), and control group. The total training program was held for four weeks. The isokinetic dynamometer, sit‐and‐reach test, Y balance test, and the intrinsic motivation inventory‐22 were used to measure the outcomes before and after the intervention. Paired sample t‐test was used to compare the changes before and after the intervention within groups, while the one‐way ANOVA was used for the comparison between the groups. Results of the study showed that, after four weeks of intervention, balance, muscle strength, and muscle endurance in all groups significantly improved except for the control group. The ART group showed the highest increase in muscle strength, muscle endurance, and balance compared to the other groups. The motivation level increased in all three feedback groups and was observed in the following order: ART group > MVFT group > TBT group > control group. This study highlighted the most effective method that may be applied for home training during and after this period of the pandemic. The findings revealed that training while receiving real‐time feedback via AR devices improves both physical performance and motivation. Augmented reality‐based training can be used as an effective training option for improving physical activity and motivation and can be suggested for home training programs.

The purpose of this preliminary study was to evaluate the feasibility of multiplayer game contents with dual-task exercises using augmented reality (AR) and a personal health record (PHR) system for social skills and cognitive function in children with autism. The present study used a single group pretest–posttest study design with fourteen children diagnosed with autism and aged 6–16 years. The intervention consisted of various game contents designed specifically with cognitive and motor tasks, performed for 30 min per session, twice a week, for three weeks. Outcome measures were conducted before and after the intervention and included social skills and cognitive function. A satisfactory survey was conducted post-intervention to assess the usability of the performed games. As result, statistically significant improvements were observed in all subscales of the social skills and cognitive function expected in two subscales of each measured outcome. Parents and children appreciated the overall game program, and no risk of injury and dizziness were mentioned. This preliminary study found that multiplayer game-based dual-task training using AR and PHR was feasible and has a promising efficacy for children with autism. However, there is the need to conduct a randomized control study with a large sample size.

There is growing interest in using augmented reality (AR)-based training for rehabilitation programs, while it remains unclear whether physical exercises using AR can be more effective than conventional therapy for patients with total knee replacement (TKR). This study, therefore, aimed to compare the effects of AR-based training to conventional therapist-based training on the physical performance of early-stage rehabilitation in patients after a TKR. It was a double-blind randomized controlled trial with repeated measures (pre-surgery, post-surgery, and post-intervention). Twenty-four participants with TKR were allocated to either AR-based training or therapist-based training. Both groups received a training program for 30 min per session, three sessions per week, for four weeks. The outcome measures included the range of motion (ROM), muscle strength, balance, and perceived pain. The results showed significant improvements in all measured outcomes in both groups (p < 0.05). However, despite our hypothesis that ART would be more effective than the TKR, no significant differences in all the outcomes were found between the two groups. While there was some evidence showing that performing physical exercises using AR could improve physical performance in patients with TKR after surgery, a comparison with conventional therapy did not show superior effectiveness. However, AR could be used to provide real-time feedback and motivation appropriate for home-training programs.

Objective: Exergames are playing an important role in person-centered therapy, health care services, and in the rehabilitation field. This study aimed to compare the effects of cooperative, competitive, and solitary exergames on cognition and anxiety levels in children with developmental disabilities (DD). Materials and Methods: This study was a randomized controlled trial pretest–posttest including 36 children with DD who were allocated to the cooperative exergame group (CGG), competitive exergame group (CmGG), and solitary exergame group (SGG). The exergame program was performed two times a week for 8 weeks and the outcome measurements were conducted before and after the program. A paired sample t-test and one-way analysis of variance (ANOVA) were used to analyze the changes within and between the groups. Results: The result indicated a significant improvement in memory, attention, and visual perception in all groups; the CGG and CmGG showed a high increase in attention compared with the SGG. However, only the CGG presented a significant improvement in the language subscale. In terms of anxiety, only the CGG presented substantial improvements in all anxiety subscales. The CmGG showed improvement in social phobia and the SGG in physical injury fears, social phobia, and general anxiety fears. Conclusion: The findings suggest that cooperative and competitive exergames may be used to effectively improve cognitive functions; cooperative exergames can be applied as the most effective method to reduce anxiety compared with the other game types for children with DD.

Caffeine is considered a widely consumed natural and legal psychoactive stimulant with several effects on the body. The present study attempted to investigate the effects of caffeine consumed before and after a physical exercise on cardiovascular and cardiorespiratory functions in healthy adults. 36 healthy adult males were recruited and randomly allocated to one of the three (3) groups: group I (exercise without caffeine consumption), group II (caffeine beverage intake before exercise), and group III (caffeine beverage intake immediately after exercise). The heart rate (HR), QTc interval, blood pressure (BP), respiratory rate (RR), oxygen consumption (VO₂), and carbon dioxide emission (VCO₂) were measured at 0, 5, 10, and 15 min after the exercise. We observed a significant difference in all measured outcomes during the different recovery times in all the groups (p < 0.05). HR, RR, SBP, VO₂, and VCO₂ gradually decreased with time, DBP contrarily increased with time, and the QTc showed an irregular pattern. We can affirm that ingestion of caffeine before and after moderate aerobic exercise slows down the parasympathetic stimulation, heart rate recovery, and the recovery of HR and QTc with no major effects on BP, RR, VO₂, and VCO₂ in healthy adult men.
