Kinetic And Kinematic Evaluation Of Compensatory Movements Of The Head, Pelvis And Thoraco-Lumbar Spine Associated With Asymmetrical Weight Bearing Of The Pelvic Limbs In Dogs, David Alan Hicks
Doctoral Dissertations
The purposes of this dissertation were to 1) determine ground reaction forces of dogs with mild asymmetrical weight-bearing of the pelvic limbs while trotting and 2) use three-dimensional motion analysis to identify compensatory vertical motion of the head and pelvis, and lateral motion of the thoraco-lumbar spine in dogs with mild asymmetrical weight-bearing of the pelvic limbs while trotting, and 3) use this information to introduce a subjective grading system for the pelvic limbs in dogs. Our hypotheses were that dogs with asymmetric weight bearing demonstrate compensatory motions of the head, pelvis and thoraco-lumbar spine while trotting, and that these …
Effects Of Increased Step Width On Knee Joint Biomechanics In Healthy And Knee Osteoarthritis Older Adults During Stair Descent, Maxime Robert Paquette
Effects Of Increased Step Width On Knee Joint Biomechanics In Healthy And Knee Osteoarthritis Older Adults During Stair Descent, Maxime Robert Paquette
Doctoral Dissertations
Stair negotiation is one of the most challenging tasks for older adults especially for those suffering from knee osteoarthritis (OA). To date, no studies have investigated the effects of increased step width (SW) on knee joint biomechanics. The purpose of Study One was to investigate the effects of increased SW on peak internal knee abduction moment and other lower extremity variables during stair descent in healthy older adults. The purpose of Study Two was to investigate the effects of increased SW on peak internal knee abduction moment, knee pain and other lower extremity variables during stair descent in medial compartment …
