Problem
Addressed

Foot drop is a neurological and muscular condition that affects the ability to lift the foot towards the individual’s body and away from the ground causing difficulty while walking. This is often caused by muscular disorders, nerve injuries, or neurological condition’s like stroke or multiple sclerosis. Physiotherapy for foot drop involves repetitive exercises with the help of a therapist that may not be affordable or consistently accessible for everyone. This project aims to provide a portable and cost-effective device that provides ankle movement to achieve recovery through repetitive motion and muscle activation.

About the
Technology

  • The device developed is an Arduino-based rehabilitation system. It consists of a DC gear motor controlled via a motor driver, push buttons, and an LCD interface.
  • The system delivers dorsiflexion/plantarflexion to the foot using a linkage mechanism. This movement is helpful for retraining muscles and nerves.
  • Multiple operating modes such as continuous, manual, and preset modes with adjustable parameters like speed, angle and cycles.
  • Intuitive wired remote interface using buttons for easy parameter setting and the LCD screen displays current mode and settings selected.

Application Areas & Use Cases

  • The device developed is an Arduino-based rehabilitation system. It consists of a DC gear motor controlled via a motor driver, push buttons, and an LCD interface.
  • Home-based physiotherapy for patients having mobility challenges, and rural and low-resource areas where access to full-time physiotherapists is limited.
