A wearable gait analysis system composed of mobile six-axial force plates and multi-axial motion sensors is capable of gait analysis in non-laboratory environment. Triaxial ground reaction force (GRF), triaxial joint angle, joint force and joint moment for the three joints of lower limbs were extracted using the measured data. Presently, we have discussed the components of main axis of these experiment results. GRF, joint angle and joint force showed reasonable agreement with the reference system composed of an optical motion analysis system and stationary force plate (average RMSE of 5.5° and correlation coefficient of 0.94). Only the x-axial moments of ankle and hip showed relatively low consistency.
