Mathematical calculations of muscle forces often require an estimate of a given muscle’s capacity to generate force. A traditional way of expressing a muscle’s fora generating capacity is in terms of its ‘physiological cross-sectional area’ (degned by muscle volume or muscle mass divided by either gross musck length or muscle fiber length with or without accounting for pennation) (Brand et al.....

High-performance artificial muscle is always the pursuit of researchers for robotics. Herein, a bionic reported called “ExoMuscle” mimicking sarcomere in skeletal with bio-inspired structure to contract “myofilaments” enabling mimic architecture such as parallel, fusiform, convergent, and pennation beyond performance muscle. The actuators excel various aspects compared including actuation stres...

BACKGROUND Estimation of an individual muscle force still remains one of the main challenges in biomechanics. In this way, the present study aimed: (1) to determine whether an elastography technique called Supersonic Shear Imaging (SSI) could be used to estimate muscle force, (2) to compare this estimation to that one provided by surface electromyography (EMG), and (3) to determine the effect o...

BACKGROUND Retraction, atrophy and fatty infiltration are signs subsequent to chronic rotator cuff tendon tears. They are associated with an increased pennation angle and a shortening of the muscle fibers in series. These deleterious changes of the muscular architecture are not reversible with current repair techniques and are the main factors for failed rotator cuff tendon repair. Whereas fast...

INTRODUCTION The deformation of the muscle-tendon complex in response to forces depends on architectural design, tissue properties and activation patterns. In this study we derive a mathematical model of muscle which is amenable to finite element simulation, and which allows for flexible prescription of tissue properties and architecture. Architectural design within this model is characterized ...
