Clinical Report: TIC-XNet for Enhanced Detection of Pediatric Tic Events

Overview

The TIC-XNet framework demonstrates superior performance in detecting tic events in children with tic disorders by integrating video and physiological signals. It achieves high accuracy and interpretable outputs.

Background

Pediatric tic disorders are neurodevelopmental conditions that present challenges in clinical evaluation due to their variable expression across contexts. Current assessment methods rely on subjective observations, highlighting the need for objective, continuous monitoring approaches.

Data Highlights

MetricTIC-XNetComparator Models
Window-level AUC0.915 ± 0.019Lower
Event-level recallHigherLower
Event-level precisionHigherLower
Missed eventsFewerMore
Post-buffering prediction latencyLowerHigher

Key Findings

  • TIC-XNet achieved a window-level AUC of 0.915 ± 0.019.
  • It demonstrated higher event-level recall and precision compared to comparator models.
  • The framework resulted in fewer missed events and lower post-buffering prediction latency.
  • Translated outputs from TIC-XNet showed higher decision fidelity and stability under perturbation.
  • Subject-level translated signals were associated with tic severity.

Clinical Implications

The TIC-XNet framework provides a method for detecting tic events, integrating multimodal data.

Conclusion

TIC-XNet represents an advancement in the detection of tic events in children, combining predictive performance with interpretable evidence outputs.
