Fast, reliable gait analysis using the FDM measuring system for force distribution The basic measuring system comprises an FDM 1.5 or FDM 2 measuring plate for force distribution and the software package, WinFDM. The system is controlled by a PC with a USB interface and the operating system, Windows XP or Windows Vista. By combining two platforms of the same type, the gait length can be doubled. The measurement and the evaluation are processed on the computer using the WinFDM program. For this procedure, the measuring data of the floor reaction forces, the video camera and, if applicable, the EMG and angle data are evaluated synchronously. The measuring sequence can be repeated in a "Viewer" and, if necessary, shown in slow motion. Individual time segments can be selected in the report for further analysis. After defining the left and right floor contacts, the automatic analysis of the measuring cycles is produced in the results report. All the screen contents can be printed out as an instantaneous recording. The measuring results are presented in an easily readable layout in the result report and printed out in color using a commercially available printer. Up to three measurements can be compared directly with each other as a procedural control. All the pages in the report can be configured freely as regards the arrangement, size and position of the evaluation windows.
