This paper is about a separation method of resultant ground reaction force data during double stance phase in gait. When ground reaction force data in gait on a traditional treadmill are measured, it is difficult to set force plates on either side of the treadmill independently. Therefore, the resultant ground reaction force data are measured during double stance phase. In order to solve this problem, we proposed a separation method of the resultant data using a ground reaction force model that is based on pre-measured data of 10 healthy adults. Detected double stance phase with this method is accurate within about ordinary video rate, and this method can separate both ground reaction force data from the resultant data. Furthermore, we confirmed that this method can be adaptable for the measured data with a different gait speed or with an asymmetrical gait pattern.
