Tibial Shock Real Time Feedback
- Monitoring impact level (Pavement – Trail – Treadmill)
- Reduction of impact loading through gait retraining
- Evaluate running shoes impact absorption characteristics at the tibia.
- Ground reaction forces assessment
Runners know how common overuse injuries can be. The new TgForce 3D sensor and its associated App provide the following features:
- 3D 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 wireless sensor
- Free TgForce 3D 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)
- Monitor impact level by checking data recorded in the sensor
The Latest in Sensor Technology
While other running technologies provide sensors attached to your shoes, the wireless TgForce 3D 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.
It has been demonstrated that Peak Tibial Acceleration is strongly correlated to vertical force loading rates. Reducing lower extremity loading may help in preventing a tibial stress fracture. An independent study has shown that TgForce data is strongly correlated with vertical loading rate (IEEE Sensors Journal).
The wearable sensor records all steps and 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.
The new TgForce 3D sensor is lighter and sports new features for comprehensive analysis
