  • Implementation of a semi-automated annotation process using the data pipeline.
  • Training and testing a convolutional neural network (CNN) for gait classification (hemiplegic vs. diplegic).
  • Data preprocessing, model training, and evaluation on a holdout test set.

    • Main Results:

    • The data pipeline successfully created a semi-automated annotated dataset.
    • A simple convolutional neural network achieved an accuracy of 0.78 on a holdout test set.
    • The model demonstrated a median performance of 1.0, indicating strong classification ability for the tested gait types.

    Conclusions:

    • The novel data pipeline effectively structures and semi-automates the annotation of clinical gait analysis data.
    • Machine learning models, like CNNs, can be successfully trained on data processed through this pipeline for gait classification.
    • This approach shows promise in reducing the time and effort required for gait analysis, potentially improving diagnostic efficiency for children with cerebral palsy.
