Aligning Anatomical Knee Model With Kinematic Experimental Data To Investigate Squat Exercise, Jose Mario Salinas
Aligning Anatomical Knee Model With Kinematic Experimental Data To Investigate Squat Exercise, Jose Mario Salinas
Theses and Dissertations
A two-dimensional inverse dynamics anatomical model of the human knee was developed by aligning anatomical structures of the knee (taken from x-rays) with kinematic experimental data (collected from motion capture cameras). The mathematical model was used to study the forces related to the tibiofemoral and patellofemoral joints during the squat and knee extension exercises. Forces calculated by the model included: tibiofemoral contact force, patellofemoral contact force, forces generated by cruciate ligaments, quadriceps force, and patellar tendon force. Bone alignment consisted of superimposing the geometric center of the lateral femoral condyle (from x-rays) with the relative instantaneous center of rotation of …
Multi-Objective Design Optimization Of Reverse Total Shoulder Arthroplasty To Maximize Range Of Motion And Joint Stability, Josie A. Elwell
Multi-Objective Design Optimization Of Reverse Total Shoulder Arthroplasty To Maximize Range Of Motion And Joint Stability, Josie A. Elwell
Graduate Dissertations and Theses
Reverse total shoulder arthroplasty was developed to restore range of motion (ROM) and joint stability to patients with pre-operative conditions that are not addressed by conventional replacements. Although reverse total shoulder arthroplasty is the current gold standard for treating a range of indications, the effects of varying its design on functional outcomes of the procedure are still not well understood.
To that end, it is not yet clear which configurations, in terms of both design and surgical placement parameters, maximize range of motion and stability of the joint. It was hypothesized that there is trade-off between the two. These types …
