Summary

This study explored a rule-based decision support system (DSS) for autonomous bicycle ergometer training in chronic obstructive pulmonary disease (COPD) patients. The DSS demonstrated feasibility, with patients reporting high satisfaction, suggesting potential for home-based rehabilitation.

Area of Science:

  • Pulmonary Rehabilitation
  • Medical Decision Support Systems
  • Biomedical Engineering

Background:

  • Chronic Obstructive Pulmonary Disease (COPD) rehabilitation traditionally occurs in clinical settings.
  • Automated Decision Support Systems (DSSs) offer a novel approach to supervised physical exercise training.
  • Integrating DSSs into rehabilitation can enhance patient autonomy and accessibility.

Purpose of the Study:

  • To evaluate the feasibility of a rule-based DSS for autonomous bicycle ergometer training in COPD patients.
  • To assess the safety and patient satisfaction with automated exercise load control.
  • To explore the potential of DSSs for facilitating home-based COPD rehabilitation.

Main Methods:

  • A rule-based DSS was developed for autonomous bicycle ergometer training.
  • Real-time sensor data (oxygen saturation, heart rate) informed load control.
  • Ten COPD patients completed 18 training sessions, with system performance and patient feedback recorded.

Main Results:

  • The DSS successfully managed training loads (31-47 W) based on physiological parameters.
  • An average of 7.4 rules were activated per session, indicating dynamic system response.
  • Patients reported high satisfaction and a mean Borg value of 12.6±2.4, with 45.9% and 41.6% of heart rate readings within target zones.

Conclusions:

  • The rule-based DSS is a feasible tool for autonomous bicycle ergometer training in COPD patients.
  • Automated control based on physiological data appears safe and well-tolerated.
  • This technology holds promise for enabling COPD rehabilitation in home environments, potentially improving long-term adherence and outcomes.
