Gamified Closed-Loop Intervention Enhances Tic Suppression in Children: A Randomized Trial.

Area of Science:

• Neuroscience
• Behavioral Science
• Pediatrics

Background:

• Gamification in behavioral interventions for tic disorders (TDs) may improve patient compliance.
• Games delivering immediate positive feedback for tic suppression could counteract negative reinforcement mechanisms that sustain tics.

Purpose of the Study:

• To develop and evaluate a gamified protocol (XTics) for enhancing tic suppression in children.
• To assess the clinical value of combining gamified tic-triggering with immediate feedback.

Main Methods:

• A randomized crossover design was used with 35 participants (aged 7-15 years).
• Participants completed daily gaming sessions for one week under two conditions: Immediate and Contingent Reward (ICR) and Delayed Reward (DR).
• Primary measures included inter-tic interval (ITI) and tic severity (Yale Global Tic Severity-Total Tic Score [YGTSS-TTS], Rush, Parent Tic Questionnaire [PTQ]).

Main Results:

• The inter-tic interval (ITI) showed significantly greater improvement after ICR (1442%) compared to DR (242%).
• Rush tic severity scores reduced more significantly following ICR compared to DR.
• A clinically significant reduction in YGTSS-TTS (25.69%) was observed after the 4-week protocol, with parent-reported severity decreasing by 42.99% at 3 months post-treatment.

Conclusions:

• The XTics protocol, combining gamified tic-triggering with immediate, contingent rewards, shows promise for improving tic suppression.
• This gamified approach may enhance the efficacy of traditional therapeutic methods for tic disorders.
