Cognitive functioning is an extremely crucial part of daily living. In individuals with Down Syndrome (DS) these tasks get even more challenging. The aim of this study is to determine the effects of Assisted Cycling Therapy (ACT) on cognitive functions in children with Down Syndrome (DS). This study examines the change in cognitive functioning using tests like Reaction time, Tower of London, and Card Sorting over an eight week intervention. All seven participants in the study were assigned to complete the ACT intervention, in which they rode a stationary bike with the assistance of a motor to maintain a cadence of at least 35% greater than their voluntary cycling speed. All participants completed the ACT intervention but a few were unable to complete some cognitive functioning tests due to their intellectual abilities. Overall, the results of this study showed that information processing, task-switching and problem solving improved following the eight week ACT intervention. These results provided more scope for future research in this field which can be done by modifying the time period of the intervention, increasing sample size of the study as well as conducting additional cognitive function tests. The results of our study are discussed with respect to the upward regulation of neurotrophic factors which are involved in increasing the functioning within the prefrontal cortex following exercise intervention.

The primary goal of this study is to assess and develop an understanding of the effects of Assisted Cycling Therapy on manual motor performance in children with Down syndrome. Seven children (Mage 11.6 years old) completed a 30-minute cycle session 2x/week for 8 weeks on the PACT bicycle at a 35% greater rate than their self-selected rate. Pre- and post-testing of grip force with a dynamometer and unimanual and bimanual manual dexterity using the Purdue Pegboard were measured to determine changes in force production and fine motor control, respectively. Results consistently showed improvements in grip force in both hands and bimanual dexterity following PACT. My results are interpreted with respect to cerebral lateralization and neuroplasticity following PACT intervention.

Research has shown the benefits of exercise on people with (DS), and how it affects their quality of life (Maïano et al. 2019). However, many studies have also shown that the majority of people with DS do not meet the national minimum requirements for physical activity per day (Phillips et al. 2011). The current study will focus on Pediatric Assisted Cycle Therapy (PACT) as exercise and specifically its effects on children with DS. The goal is to improve the general behavioral skills of children with DS, which in turn can improve their quality of life. We predict that, based on pilot data (Gomez, 2015; Parker, 2016), GLTEQ will increase their total activity score following 8 weeks of PACT in young children with DS. The Godin Leisure Time Exercise Questionnaire was used to measure the participants’ participation levels in leisure time activity. Participants were involved in an 8-week intervention, in which they biked (PACT) for 30 minutes, twice a week. GLETQ was measured pre and post intervention and assessed using the scale provided by the GLETQ. The data from this study has shown a positive correlation between Leisure Time Activity and PACT. Overall, a mean increase in raw activity score in the GLETQ was shown.

Reactive step and treadmill perturbation training have been shown to improve first step measurements and reduce falls. However, the effect of variable training on the efficacy of generalization is poorly understood. The objective of this study was to measure whether the addition of variability in the perturbation training protocol can increase the amount of generalization seen in forward perturbations. The study included 28 young, healthy adults between the age of 20-35 years old with no known significant medical history. Fifteen participants underwent constant training in one direction with the same belt acceleration (4 m/s2) and thirteen participants underwent variable training where their foot positioned and belt acceleration (3 m/s2, 4 m/s2, 5 m/s2) were randomized throughout the collections All slips were done in the forward direction requiring a forward reactive step. To assess the effects of variable training an independent sample t-test of the differences in generalization between each group was calculated. Primary outcome variables in both studies were margin of stability (MOS), step length, and step latency. Results from the study indicated that variable training made no significant improvement (p<0.05) in generalization across the variables. The P-values for the difference in generalization of MOS, step length, and step latency were 0.635, 0.225, 0.148 respectively. Despite the lack of significant evidence to support improvement in generalization with variable training, further investigations are warranted to develop training methods capable of reducing falls in at risk populations.

This study examines the effectiveness of two modes of exercise on self-efficacy (SE) and exercise perception (EP) in adults with Down syndrome (DS). Thirteen participants attended four sessions: a baseline assessment, an Assisted Cycling Therapy (ACT) session, a resistance training (RT) session, and a session of no training (NT). In the baseline assessment, 1-repetition max (1RM) measurements and voluntary pedal rate measurements were taken. In the cycling intervention, the participant completed 30 minutes of assisted cycling at 35 percent greater than their voluntary pedaling rate. In the resistance training session, 2 sets of 8-12 repetitions of the leg press, chest press, seated row, leg curl, shoulder press, and latissimus pulldown were performed. During the session of no training, participants played board games with student researchers for 35 minutes.Two subsets of the Physical Activity and Self Efficacy Survey were administered prior to each session (i.e., pretest) and after the intervention (i.e., post-test). The results were consistent with the hypothesis that ACT would lead to higher SE than RT or NT. However, ACT did not lead to higher EP than RT or NT as hypothesized. Additionally, it was hypothesized that RT would lead to higher SE and EP than NT, but the results did not support this. In conclusion, an acute session of ACT demonstrated a significant trend for improved self-efficacy in adults with DS.

Down syndrome (DS), which is determined by an extra 21 chromosome, is one of the most common developmental disabilities across all races and societies. One of the hallmarks of people with DS is that they have deficits in cognitive control compared with their peers. In addition to broad cognitive impairment, persons with DS have physical characteristics which limit their ability to perform activities of daily living (ADL) including deficits in fine motor control needed for handling money, self-care, eating, etc. As the relative prevalence of DS at birth lessens, and as life expectancy increases, DS will be most commonly represented amongst the elderly. Thus, intervention is needed in older adults with DS to improve their manual dexterity to sustain their independence and quality of life. The aim of this study was to examine the influence of Assisted Cycling Therapy (ACT) compared to voluntary cycling (VC) and no cycling (NC) on fine motor control in older adults with Down Syndrome (DS). Twenty-five older adults with DS were randomly assigned to one of three, 30 minute interventions, which took place over an eight-week period of time. 1) Thirteen older adults with DS completed the ACT intervention, which is stationary cycling with the assistance of a motor to maintain a cadence at least 35% greater than voluntary cycling. 2) Ten older adults with DS completed voluntary cycling (VC) and 3) Two older adults with DS were in our no cycling (NC) intervention. Fine motor control was measured with the Purdue Pegboard placing pegs in small holes in 30 s with the right hand alone, the left hand alone, and bimanually pre and post 8 weeks of intervention. Our results showed that bimanual and total score (i.e., right, left and bimanually) fine motor control improved following both ACT and VC cycling exercise but not NC. This suggests that 30 minutes of exercise over 8 weeks has some positive effects on manual dexterity. Different mechanisms for this improvement will be discussed. This information is important to the independence and quality of life of older adults with DS.
