TgForce Impact sensor for running

TgForce - Impact Sensor

Monitor & Maintain Low Impact

Available April 2019

Real Time Feedback Made Easy

Runners know how common overuse injuries can be. The TgForce sensor and its associated App provide the following features:


  • Peak Positive Acceleration of the tibia while running
  • Impact information in real time through Visual or Audio feedback
  • Real time tibial shock & cadence data for evaluating and transitioning to a lower impact running gait
  • Charts and Exportable data for further analysis
  • A lightweight Bluetooth Smart Sensor
  • Free companion App available on the iTunes App store

gMax Threshold

Set a specific maximum g threshold  (the gMax), and the App will let you know immediately if you exceed it while running.

  • Treadmill Running? Try using the Visual Feedback on your iPhone or iPad
  • Outside on the track? Use the Audio feedback (while listening to your favorite music)

The Latest in Sensor Technology

While other running technologies provide sensors attached to your shoes, the wireless TgForce sensor is meant to be attached directly to your body (the anteromedial aspect of the distal tibia).

This is the method used by multiple scientific studies, and it assures you are obtaining meaningful impact data.

The wearable sensor provides impact data in real time. You are free to review the data at a later time, but you’ll obtain greater benefits if the data is immediately delivered.
