Adaptive behavior consists of the social, conceptual and practical skills an individual must execute to function independently in their everyday life. Individuals with Down syndrome have limitations in their adaptive behavior due to cognitive and physical deficits. The aim of this study was to examine if an exercise program would improve the adaptive behavior skills in persons with Down syndrome. The exercise intervention, Exercise for Adults with Down Syndrome (ExDS), was a semester long program where adults with Down syndrome participate in twice weekly workouts planned and executed by Arizona State University students. The workouts consisted of an aerobic warm up, aerobic exercises, resistance exercises, balance exercises and stretches. The participants' adaptive behavior and cognitive planning ability were assessed before ExDS and after ExDS. The Adaptive Behavior Assessment System Second Edition (ABAS-II) was used to measure adaptive behavior. The ABAS-II consisted of a forum that addressed the Social, Conceptual and Practical domains of adaptive behavior and was filled out by the participants' caregiver. The Tower of London (ToL) was used to measure cognitive planning ability. The change in the ABAS-II scores from pre- to post-testing were statistically insignificant. The change from pre- to post-testing in the ToL scores approached statistical significance. Limitations included bias caregiver perception and respondent inconsistency. There is a need for further research on the effect of exercise on the adaptive behavior in adults with Down syndrome.

Effects of Assisted Cycling Therapy on Inhibition in Stroke Survivors

Executive function is vital for activities of daily living especially in stroke survivors because it is critical to everyday tasks (e.g., driving, cooking, etc.). An innovative way to improve executive function may be Assisted Cycling Therapy (ACT). This is among the first studies to use a Stroop task to measure inhibition, selective attention, and information processing speed following ACT in stroke survivors. Twenty-three participants post-stroke performed ACT, voluntary cycling (VC) and no cycling (NC). The results showed that there were improvements in the Stroop task following an acute session of ACT but not following VC or NC. These results suggest that ACT resulted in increased afferent information which may have resulted in increased arousal and excitability in regions of the prefrontal cortex. These factors have been shown to improve executive function.

REFLEX: Relative Executive Function Level Examination

The goal of this thesis project was to develop a digital, quantitative assessment of executive functioning skills and problem solving abilities. This assessment was intended to serve as a relative measure of executive functions and problem solving abilities rather than a diagnosis; the main purpose was to identify areas for improvement and provide individuals with an understanding of their current ability levels. To achieve this goal, we developed a web-based assessment through Unity that used gamelike modifications of Flanker, Antisaccade, Embedded Images, Raven’s Matrices, and Color / Order Memory tasks. Participants were invited to access the assessment at www.ExecutiveFunctionLevel.com to complete the assessment and their results were analyzed. The findings of this project indicate that these tasks accurately represent executive functioning skills, the Flanker Effect is present in the collected data, and there is a notable correlation between each of the REFLEX challenges. In conclusion, we successfully developed a short, gamelike, online assessment of executive functioning and problem solving abilities. Future developments of REFLEX could look into immediate scoring, developing a mobile application, and externally validating the results.

Background: Down syndrome is the leading genetic cause of intellectual disabilities. Executive function is an area that people with Down syndrome have a diminished capacity compared to those in the general population. In recent years it has been determined that acute and chronic exercise has a small but positive effect on measures of executive function in typically developed individuals. The effect has been recorded separately in both aerobic, high-rate passive and resistance exercises in adolescents with DS but has not been compared between exercise types in adults with DS. Methods: A randomized crossover study was utilized to determine the effect of resistance exercise, assisted cycling therapy, and no exercise on executive function and enjoyment in adults with Down syndrome. Resistance Training (RT)- participants completed a total of 16- repetitions of approximately 75% of a 1-RM in the leg press, chest press, seated row, and latissimus pulldown. ACT- participants completed 30-minutes of cycling at 35% above voluntary (e.g., self-selected pace) rate. No-Training (NT)- participants spent 35-minutes playing board games. Cognitive assessments were recorded pre- and post- intervention. The Physical Activity Enjoyment Survey was collected post-intervention. Statistics: The cognitive measures and Physical Activity Self-efficacy scale were analyzed using the delta scores (pre-post) in a Linear mixed models analyais. The main effect of sequence (A, B, C) and intervention (RT, ACT, NT), and visit were assessed. Significance level was set with α=0.05. If any differences were detected, the Bonferroni post-hoc test was used to determine differences. Physical Activity Enjoyment Scale post scores were compared using a General Linear Model. Alpha was set at 0.05 with a Bonferroni post-hoc test to determine differences. A secondary analysis was conducted investigating the effect of participants that completed testing individually compared to those that completed the testing in a group setting. Results: There were no significant difference in the delta score of any of the measures. The secondary analysis also found no significant difference but showed a trend that those tested individually had opposite results than those tested in a group.
