Therapeutic Intervention Or Rider Influence On The Electromyographic Activity And Kinematics Of Horses, Karen L. Shaw
Therapeutic Intervention Or Rider Influence On The Electromyographic Activity And Kinematics Of Horses, Karen L. Shaw
Masters Theses
Core strengthening and postural stability are desired outcomes of certain therapeutic exercises performed in horses. This study aimed to quantify changes in muscle activation at a walk and trot in horses traveling over eight consecutive ground poles evenly spaced (at 30 inches for walk and 48 inches for trot) in parallel fashion in a straight line, and with hindquarter and abdominal elastic resistance bands applied at 25% stretch. Surface electromyography (sEMG) data were collected for the longissimus dorsi and rectus abdominus muscles in six horses. A 2x2 repeated measures ANOVA was performed for each muscle to test for significant differences …
Knee Biomechanics Of Older Adults During Common Recreational And Daily Activities, Julie Lynn Pfeiffer
Knee Biomechanics Of Older Adults During Common Recreational And Daily Activities, Julie Lynn Pfeiffer
Masters Theses
Among older adults, socialization is a key motivating factor for participation in physical activity. In order to develop evidence-based physical activity recommendations for older adults with knee pathologies a better understanding of knee biomechanics during social recreational activities is needed. The purpose of this study was to determine knee joint kinematics and kinetics in healthy older adults during golf and bowling. Knee biomechanics during these recreational activities were also compared to those experienced during activities of daily living. Motion analysis data were collected as subjects performed walking, stair ascent, stair descent, and either golf or bowling. Knee angles, peak knee …
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 …
