GaitorAID: Running Feedback Tool

Coursework Design Project

Project Description

Coursework design project (ES227, Medical Device Design).

Student Team: Cassie Lowell, Jessi Herrmann, Harnek Gulati, Frank DuBose.

Advisors: Hao Su (PhD student), Prof. Conor Walsh.

In conjunction with the 
Wyss Institute for Biologically Inspired Engineering , & the Spaulding National Running Center.

The student team designed a wearable sensor that can monitor a runner’s tibial angle and tibial acceleration in the field via an inertial measurement unit (IMU). The device can segment the gait cycle in real time, and utilize an algorithm that determines overstride. The device uses the algorithm’s calculations to provide real-time feedback to the user to help correct running form and prevent injury.

Project Details
  • Sensor is placed on a specialized compression sock during wear, but is removable for washing

  • Includes a one-step calibration for optimizing data collection

  • Provides real-time visual feedback to runner about form

  • Algorithm effectiveness confirmed with motion capture at the Harvard Medical School
