Area of Science:

Digital Health
Biomedical Engineering
Data Science

Background:

Wearable inertial sensors offer valuable patient mobility and health data.
Limited availability of open-source software tools for processing daily living activities from sensor data.
Lack of readily available code for research replication and off-the-shelf software packages.

Purpose of the Study:

Introduce SciKit Digital Health (SKDH), an open-source Python package.
Provide algorithms for deriving clinical features from wearable sensor data.
Streamline digital endpoint generation for research and clinical applications.

Main Methods:

Developed SKDH as a Python software package.
Integrated algorithms for gait, sit-to-stand, physical activity, and sleep analysis.
Designed an extensible framework for data ingestion, preprocessing, and analysis.

Main Results:

SKDH offers a unified pipeline for digital health data processing.
The package promotes reproducibility through a convention-over-configuration approach.
Standardized settings are provided for healthy and mildly impaired adult populations.

Conclusions:

SKDH simplifies the creation of digital health data processing pipelines.
The open-source package facilitates reproducible research in digital health.
SKDH is freely available under an MIT license for use and extension.
