A Method to Estimate Finger Muscle Activation Levels from the Variation of Fingertip Forces against Disturbances based on a Musculo-skeletal Human Hand Model

Abstract (in Japanese) (See Japanese page) 
(in English) To analyze human hand dexterity, activation levels of finger muscles must be estimated. Although surface EMG is a noninvasive method, cross-talk problem makes it difficult to estimate muscle activities, especially those of intrinsic muscles. To solve this problem, we propose a method to estimate activation levels of finger muscles by observing variation of fingertip forces against disturbance so that the relationship between S-EMG signals and estimated activation levels is identified . In this paper, we confirm the validity of the proposed method by actually applying disturbances to a muscle-skeletal model of the index finger in computer simulations.
