Validation of RunScribe inertial sensor for measuring foot strike angle
This project was completed as a group of four in my Biomechanics and Sports Engineering Measurement Techniques module.
A twelve camera 3D motion capture system was used to evaluate the accuracy and reliability of the RunScribe. The RunScribe is an advanced running wearable that uses an inertial measurement system to measure metrics such as contact time, stride length, foot-strike type, impact Gs and pronation excursion.
The three general categories when describing foot-strike type are heel, midfoot, and forefoot strikers. From recent publications regarding foot-strike type, injury and running economy, the foot-strike angle at contact was chosen to be validated.
The goal of the project was to validate the RunScribe for measuring foot strike angle during running with the ‘gold standard’ 3D motion capture system.
The results of the project showed reasonable agreement for the foot-strike angle between the RunScribe and the motion capture system. This validated and showed promise that the RunScribe can be used for determining runner’s foot-strike type when used in a field-based setting.
