Background:

Falls are a major cause of injury and death in the elderly.
Wearable sensors offer a non-intrusive solution for monitoring at-risk individuals.

Purpose of the Study:

To develop and validate a machine learning model for detecting falls and activities of daily living (ADL) using wearable sensor data.
To distinguish between fall events and normal ADLs.

Main Methods:

Collected accelerometer data from 35 healthy individuals performing various ADLs and simulated falls.
Extracted spatial and frequency domain features from the sensor data.
Trained supervised machine learning models to classify fall versus non-fall events and ADLs.

Main Results:

Achieved a 98.41% F1-score for distinguishing fall from non-fall events.
Achieved an 88.11% F1-score for distinguishing between various ADLs, including falls.
The "ShimFall&ADL" dataset was created and will be publicly released.

Conclusions:

The proposed approach using wearable sensors and machine learning is highly effective for fall detection.
The public release of the ShimFall&ADL dataset will support future research in this critical area.
