Heel Raise Measurement Device for Plantarflexion Physiotherapy

In a typical heel raise exercise for patients undergoing rehabilitation, the physiotherapist often determines how much the feet have raised through visual inspection. For older patients, the balance training starts from forward/backward sway control of the ankle.

  • Patients perform heel raise exercises to strengthen muscles around the ankles, with the physiotherapist making a visual estimate of the extent of the patient’s heel raise.
  • Errors may occur due to inaccurate estimations, thus leading to less effective rehabilitative exercises.

Key Innovation

  • Design a contactless heel raise device to sense, measure, record, analyse, display, and provide feedback to heel raise exercising users.


  • Alleviate workload of physiotherapists.
  • Provide more accurate analysis of the exercise outcomes. As patients perform heel raise exercises, the device can track and record data, allowing a therapist to better understand the patients’ progress.
  • Potential development of mobile applications, interactive interfaces, and algorithms to allow user feedback on the heel raise measurement device.
