Following a rise in the elderly population, falling accidents caused by muscle weakness of the lower limbs will increase. This paper focuses on muscle force in each muscle of the lower limbs as an indicator for the fall risk assessment, and proposes a new estimation method of muscle force. The proposed method enables to estimate muscle force during training by determining the activity level of each muscle from the posture and force information at the center of pressure. The effectiveness of this method is shown through comparison between this method, IEMG, and a conventional method.
