Injury to a runner is largely associated with how a runner’s foot hits the ground, with some research suggesting that heel or forefoot strikes may result in stress fractures or Achilles tendinitis. Now, runners can receive corrective feedback in real-time thanks to a device developed by researchers at the Hong Kong Polytechnic University.

The mobile biofeedback device offers footstrike modification to prevent running injuries or to offer rehabilitation to already injured runners.

According to research, midfoot strike is the ideal pattern for a runner but it is difficult for runners to achieve. Through a smartphone app, the device provides real-time feedback about modifying gait mechanics to prevent injury.

In addition to offering real-time feedback, other features of the device include high accuracy, low cost and continuous outdoor monitoring.
