Methods: The embodiment of this vision was a pressure measurement insole and optical knee angle sensor system capable of wirelessly logging data. A participant was equipped with an experimental version of the system and performed various gaits along a motion-lab runway. A Vicon system tracked the participant's motion along the runway and an embedded force plate measured contact forces. The motion-lab reference data was used to validate the system and identify correlations that could aid with data interpretation and possible applications of the system. Results: Validation of the insole device showed good correlation with reference data (r>0.9) for centre of pressure location and an accuracy of +/-0.2 ms for all timing parameters. The joint angle sensor demonstrated an accuracy of within +/-3 degrees. Further correlations in the data were identified enabling classification of gait patterns. Conclusion: The system proved to be reliable, robust and accurate enough to be used in a variety of "in the field" research and rehabilitation quantification product scenarios previously rendered impractical by existing technology products. © 2010 The authors and IOS Press.
