OpenSim Models
OpenSim is a freely available, open-source software platform for modeling, simulating, and analyzing the neuromusculoskeletal system. Developed at Stanford University, OpenSim enables researchers to build and analyze musculoskeletal models, perform inverse kinematics and dynamics, and simulate movement. OpenSim models are particularly valuable for biomechanics research, rehabilitation, and sports science applications, including detailed analysis of golf swing mechanics.
Available Models
Golf Swing Musculoskeletal Models
Full-body musculoskeletal models of the golf swing, including detailed muscle-tendon units, joint kinematics, and force analysis. These models enable analysis of muscle activation patterns, joint torques, and energy transfer throughout the swing.
Inverse Kinematics and Dynamics Models
Models for performing inverse kinematics (computing joint angles from marker positions) and inverse dynamics (computing joint torques from motion data) for golf swing analysis and other biomechanical movements.
Forward Dynamics Simulations
Forward dynamics models that simulate movement from muscle activations and external forces, allowing for predictive analysis and optimization of golf swing mechanics.
Muscle-Tendon Models
Detailed models of muscle-tendon units with Hill-type muscle models, enabling analysis of muscle force production, energy consumption, and coordination patterns in complex movements.
