To determine the extent to which the Apollo System is effective in reducing symptomatology associated with ADHD.
The objective of this project is to understand the potential therapeutic benefits of the Apollo System for children with ADHD. Using vibrational therapy, the Apollo System has been previously demonstrated to promote greater balance of the autonomic nervous system. Given the importance of the autonomic nervous system for modulating levels of physiological arousal and in-turn governing aspects of attention and self-regulation; a therapeutic approach to promote better balance of this system may be particularly beneficial for populations such as children with ADHD. Accordingly, using a double-blind randomized placebo-controlled design this investigation will assess the extent to which the Apollo System is effective in reducing symptomatology associated with ADHD.

Change in ADHD symptomatology as assessed using the ADHD-5 Rating Scale
At pre and posttest, the parents/guardians of participants will complete the ADHD-5 Rating Scale. The behaviors included in the survey are derived from the diagnostic criteria for ADHD established in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition. Scores are summated into inattentive and hyperactive-impulsive symptom domains and transformed into symptom percentile scores based upon normative data based on age and biological sex. Change in the overall ADHD percentile will be considered as the primary outcome. A more negative change would indicate a better outcome reflective of reduction in ADHD related symptomatology.
Time frame: Prior to and following the 8 week study protocol period.
Effect Size for Change in Behavioral Index of Interference Control
At pre and posttest, participants will complete a version of the Eriksen flanker task. Response accuracy will be quantified within each congruency as the proportion of correct responses relative to the number of trials administered. The effect size of the change from pre-to-posttest in overall response accuracy will be considered as the primary outcome. Effect sizes will be computed per Arm and do not reflect comparisons or combinations across Arms/Groups using the repeated measures variance correction for Cohen's d (Lakens, 2013).
Time frame: Prior to and following the 8 week study protocol period.
Effect Size for Change in Behavioral Index of Response Inhibition
At pre and posttest, participants will complete a version of the go/nogo task. Response accuracy will be quantified as the proportion of correct responses relative to the number of trials administered for target stimulus trails and nogo stimulus trials separately. The effect size of the change from pre-to-posttest for response accuracy to the nogo condition will be considered as the primary outcome. Effect sizes will be computed per Arm and do not reflect comparisons or combinations across Arms/Groups using the repeated measures variance correction for Cohen's d (Lakens, 2013).
Time frame: Prior to and following the 8 week study protocol period.
