Estimation of femoral and tibial accelerations during gait using the exoskeleton (femoral and tibial parts) and rigid bodies (including accelerometer, gyroscope, and reflective markers) where a→e represents the external acceleration, and a→i the internal acceleration, for femur and tibia, respectively.
