Abstract
This paper addresses a hypothesis of estimating elasticity of flexor digitorum muscle and tendon by measuring angle of MP joint. For ease of measurement and estimation, we propose a simplified musculoskeletal model of stretching of muscle-tendon complex (MTC), and formulate relationship between joint angle and resultant fingertip force attributed to MTC stretching. In addition, relationship between joint angle and angular velocity of released finger is also approximated. These hypothesis and approximation are verified by measurement experiments.
