The Bio-Mechanical Development And Kinematic Evaluation Of Zone I And Zone Ii Injuries And Their Corresponding Surgical Repair Techniques Using An In-Vitro Active Finger Motion Simulator: A Cadaveric Study, Mohammad Haddara
Electronic Thesis and Dissertation Repository
Research development involving large scale joint mechanics and biomechanical adaptations is growing. However, interest in smaller scale joints, such as the fingers, is limited. Thus, the present work describes the enhancement and clinical application of a previously designed in-vitro active finger motion simulator in measuring and assessing intrinsic joint kinematics and tissue biomechanics including load transfer and strains induced tissues within the finger. Accuracy of electromagnetic tracking (EM) systems were evaluated compared to the standard optical tracking systems and used to develop motion derived finger joint coordinate systems. Moreover, minute strain gauges were utilized to measure strains induced by the …
Development Of An Active Finger Motion Simulator: With In-Vitro Assessments Of Tendon Loads And Joint Kinematics, Mohammad Haddara
Development Of An Active Finger Motion Simulator: With In-Vitro Assessments Of Tendon Loads And Joint Kinematics, Mohammad Haddara
Electronic Thesis and Dissertation Repository
Musculoskeletal injuries of the finger far outnumber those of other joints, and while in-vitro motion simulators are useful for studying joint biomechanics and evaluating surgical repairs, considerably less simulator development has been reported for the finger compared to other joints. Replication of active musculoskeletal movement during in-vitro testing has been shown to be more representative of in-vivo motion patterns, and closed-loop motion controllers are the current state-of-the-art for in-vitro kinematics studies. However, an in-vitro motion simulator with closed-loop tendon load control and simultaneous tendon excursion control has not yet been reported for the finger. This thesis outlines the design and …
