Background:

Chronic pain affects older adults, impacting quality of life.
Objective assessment of pain predictors is crucial for effective management.
Wearable sensor technology offers novel ways to monitor health behaviors.

Purpose of the Study:

To evaluate movement and sleep as predictors of chronic pain.
To develop a machine learning model for predicting pain intensity and interference.
To explore sensor-based behavioral data in chronic pain research.

Main Methods:

Secondary analysis of data from older adults using sensor technologies and questionnaires.
Regression models to identify unique sensor-based predictors of pain.
Deep neural network for a classification model predicting weekly pain levels.

Main Results:

Daily step count significantly predicted pain intensity (75% accuracy) and pain interference (82% accuracy).
Sensor-based parameters demonstrated utility in predicting pain outcomes.
The developed classification model showed acceptable accuracy.

Conclusions:

Objective, sensor-derived behavioral data can serve as valuable predictors of chronic pain.
Machine learning techniques effectively identify relationships between patient behaviors and pain risk factors.
This approach holds potential for non-invasive chronic pain assessment and monitoring.
