Area of Science:

  • Biomedical Engineering
  • Rehabilitation Technology
  • Human-Computer Interaction

Background:

  • Traditional physical therapy often requires frequent clinic visits, which can be costly and time-consuming.
  • Home-based rehabilitation solutions are needed to improve patient adherence and accessibility.
  • Existing systems may lack real-time feedback and accurate performance tracking.

Purpose of the Study:

  • To introduce ARhT (Automated Relearning hand Therapy), a portable system for home-based hand therapy.
  • To enhance patient experience and accountability in physical rehabilitation.
  • To develop a system capable of accurately recognizing hand therapy gestures.

Main Methods:

  • ARhT utilizes EMG sensors and a custom computation board for data acquisition.

  • Sensor data is processed by an Android smartphone with a user-friendly graphical interface.
  • Therapists can pre-select exercises and monitor patient progress via a web application.

    • Main Results:

    • The ARhT system demonstrated over 95% accuracy in recognizing hand therapy gestures.
    • The system provides real-time user interaction, including instructions and feedback.
    • Progress tracking and session information are available for therapists.

    Conclusions:

    • ARhT offers a viable and accurate solution for home-based hand therapy.
    • The system has the potential to reduce rehabilitation time and costs.
    • ARhT enhances patient engagement and provides valuable data for therapists.
