Evaluation of pressure insoles during running

Pressure insoles could be a useful tool for measuring vertical ground reaction forces during field tests. However, several studies have indicated problems that can affect the reliability of the output of the insoles. The aim of this study was to test the reliability, durability and repeatability of Tekscan F-scan pressure insoles with 2 running tests in combination with walks across and jumps on a force platform. During the both running tests in this paper the sensitivity of the pressure insoles deteriorated rapidly. A comparison of the force output of the pressure insoles and force platform during walks and jumps showed clear differences in both the shape and magnitude of the force curves. The rapid decrease in sensitivity and frequent need of calibration of the pressure insoles make the pressure insoles not reliable and practical enough for measuring vertical ground reaction forces during running.
