Wearable accelerometers quantify functional mobility improvements in chronic disease patients undergoing rehabilitation. This technology aids clinicians and patients in tracking exercise efficacy and enhancing self-managed care and compliance.

Area of Science:

  • Biomedical Engineering
  • Rehabilitation Medicine
  • Wearable Technology

Background:

  • Functional mobility is crucial for rehabilitation in chronic diseases like cardiovascular and respiratory conditions.
  • Quantifying mobility improvements is essential for effective rehabilitation program design and patient monitoring.
  • Cognitive impairments in some patients necessitate simple, non-invasive monitoring methods.

Purpose of the Study:

  • To present a method for quantifying functional mobility improvements using patient-worn accelerometer devices.
  • To evaluate the feasibility of using accelerometers for monitoring mobility in chronic disease patients.
  • To provide feedback on exercise efficacy to clinicians and patients.

Main Methods:

  • An observational trial was conducted with 15 chronic disease patients (aged 48-86).

  • A single 2-axis accelerometer device was worn at the hip to collect movement data.
  • Accelerometer data was classified into 'Lying', 'Sitting/Standing', and 'Walking/Activity' categories.

    • Main Results:

    • The method successfully classified different movement types from accelerometer data.
    • The amount of walking was quantified and could be graphically presented.
    • The data provided insights into exercise efficacy and patient mobility trends.

    Conclusions:

    • Patient-worn accelerometers offer a viable method for quantifying functional mobility in chronic disease rehabilitation.
    • This technology can provide valuable feedback for clinicians, carers, and patients.
    • Accelerometer-based monitoring can support self-managed care and improve patient compliance with rehabilitation programs.
