Contributions of the deltoid and rotator cuff to shoulder mobility and stability

This paper uses biomechanical modeling to assess how the deltoid and rotator cuff muscles contribute to shoulder mobility and stability. The study quantifies muscle forces and joint mechanics, revealing the distinct yet interdependent roles these muscles play in controlling shoulder motion and centering the joint. Its findings support biomechanically informed approaches to rehabilitation and clinical intervention.

Insights into Acute Muscle Strain Injury Obtained with In Vivo Imaging and Finite Element Modeling

Niccolo Florentino

This study combines in vivo MRI imaging with finite element modeling to explore the biomechanical origins of acute muscle strain injuries. By simulating internal strain patterns within hamstring muscles during contraction, the work reveals how structural and mechanical factors converge to produce injury-prone regions. It advances our understanding of muscle biomechanics in high-stress athletic movements.

Finite Element Modeling of Active and Passive Behavior of the Human Tibialis Anterior

David Joda

This study presents a 3D finite element model of the tibialis anterior to simulate its active and passive biomechanical properties. It reveals how internal architecture, including fascicle curvature and aponeurosis interaction, influences force transmission and muscle mechanics under physiological loading conditions.

Modeling and simulating the deformation of human skeletal muscle based on anatomy and physiology

This paper develops and validates a finite element model for simulating skeletal muscle deformation using anatomical and physiological principles. Focusing on the tibialis anterior, it explores how internal muscle architecture, activation levels, and neuromuscular compartmentalization influence force production and biomechanical behavior during contraction.

A validated model of passive skeletal muscle to predict force and intramuscular pressure

This study developed and validated a novel skeletal muscle model for the New Zealand White Rabbit tibialis anterior that incorporates tissue fluid content and whole muscle geometry. The model accurately predicts both passive muscle stress and intramuscular pressure, demonstrating strong agreement with experimental data and offering potential applications in clinical and surgical contexts.
