Musculoskeletal Modeling Analysis Of Knee Joint Loading During Uphill And Downhill Waling In Patients With Total Knee Replacement, Tanner A. Thorsen
Musculoskeletal Modeling Analysis Of Knee Joint Loading During Uphill And Downhill Waling In Patients With Total Knee Replacement, Tanner A. Thorsen
Doctoral Dissertations
The purposes of these studies were to determine differences in total (TCF), medial (MCF) and lateral (LCF) tibiofemoral compartment compressive forces and related muscle forces between limbs (replaced, non-replaced, and control), and different slopes during uphill [0° (level), 5°, 10°], and downhill [0° (level), 5° 10°] using statistical parametric mapping (SPM). Static optimization was used to determine muscle and compressive forces for 9 patients with total knee arthroplasty (TKA) and 9 control participants during walking trials. Total , loading-response, and push-off TCF impulse were calculated. A 3×3 [Limb (replaced, non-replaced, control] × Slope (0°, 10°, 15°)] SPM[F] repeated measures ANOVA …
Lower Extremity Muscle Contributions To Acl Loading In Healthy And Acl-Reconstructed Females, Shelby Peel
Lower Extremity Muscle Contributions To Acl Loading In Healthy And Acl-Reconstructed Females, Shelby Peel
Doctoral Dissertations
Females are 16 times greater to sustain a second ACL injury compared to their healthy female counterparts. Many of these females return to play their respective sport after an ACL-reconstruction (ACLR). However, little is known about the influence fatigue in sport has on lower extremity mechanics of ACLR females. The purpose of this study was to investigate the influence muscular fatigue may have on lower extremity mechanics in healthy and ACLR females. It was hypothesized that 1) healthy control and ACLR females would demonstrate different hip, knee, and ankle mechanics, regardless of fatigue, 2) fatigue would influence hip, knee, and …
Changes In Muscle Control And Coordination In Novel Task Learning, Sangsoo Park
Changes In Muscle Control And Coordination In Novel Task Learning, Sangsoo Park
Doctoral Dissertations
Learning many daily life motor skills is critical for survival and the quality of living in humans. As children, we develop walking and running patterns to move the body from point A to B without falling, and we learn to grasp a wide variety of objects during activities of daily living. Motor skills can be properly performed by appropriate muscle activations which are controlled by the central nervous system. How does the central nervous system develop and fine-tune its control strategy to learn a new motor skill? The aim of this dissertation was to better understand how human participants alter …
