Musculoskeletal Modeling
Advancing medical diagnostic and rehabilitation efforts
Aim 1) Create a model capable of large ranges of motion with improved trunk and lower extremity muscles.
MSK models are advancing the medical field providing tools for analyzing joint kinematics and kinetics, as well as muscle functions and ligament properties. However, several models to date are developed with a specific task in mind leaving the field limited in the number of movements that can be investigated per model. OpenSim, an open-sourced MSK modeling software, provides a library of various models that can be utilized depending on the needs of the movement task. However, current models are designed with respect to a specific task, thus limiting the number of movements they can simulate. Consequently, this restricts the number of tasks that can be investigated per model. For example, the Full-Body Musculoskeletal Model of the Lumbar Spine (FBLS) is limited to analyzing gait and musculature of the trunk while assisting in the analyses of spinal loading and the lower extremities during low joint angles. Whereas a recent study, involving the Full-Body Model to Perform Deep Squatting and High Hip Flexion Tasks (FBDS), implemented extra wrapping surfaces around the knee and hip joints to mimic biarticular muscles allowing for the analysis of higher hip and knee flexion tasks, like the deep squat. However, the FBDS lacks the lumbar musculature. This is problematic since the lumbar musculature plays a key role in the stability and in movements such as squatting. Maintaining a rigid spine to eliminate any planar motion ensures that a stable posture is maintained throughout the movement and helps to avoid injuries. Therefore, there is a serious need for a model capable of large ranges of motion using wrapping surfaces, and trunk and lower extremity muscles.
Aim 2) Model the effects of microgravity relating to space-induced muscle atrophy and osteoporosis
Quantify the rate of change seen in muscle and bone structure due to space-induced muscle atrophy and osteoporosis within the MSK model capable of multiple task movements.
