Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Artificial Intelligence

Background:

  • Gait analysis is crucial for understanding neurological conditions.
  • Cognitive decline significantly impacts motor control and gait.
  • Parkinson's Disease (PD) presents distinct gait alterations.

Purpose of the Study:

  • To investigate the effects of cognitive decline on gait performance.
  • To compare gait deterioration in Parkinson's Disease with healthy individuals under dual-task conditions.
  • To apply Explainable Artificial Intelligence (XAI) for interpreting gait patterns.

Main Methods:

  • Utilized Convolutional Neural Networks (CNN) for gait pattern analysis.
  • Employed Layer-Wise Relevance Propagation (LRP), a type of XAI, for model interpretability.
  • Collected and analyzed gait data from Parkinson's Disease patients and healthy controls performing cognitive tasks.

Main Results:

  • Achieved high classification accuracies (98% F1 for PD, 95.5% combined).
  • Demonstrated robust classification for cognitive load in healthy subjects (90% ± 10% F1).
  • Identified significant gait alterations linked to cognitive decline and dual-tasking, with XAI pinpointing key contributing features.

Conclusions:

  • XAI effectively elucidates shared gait disturbances in PD and dual-tasking healthy individuals.
  • The study highlights XAI's role in understanding gait control intricacies.
  • Findings offer a novel perspective on gait analysis and cognitive load's influence.
