Data On Gait Characteristics Of Four, Five, And Six Year Old Children Using Three Dimensional Video Motion Analysis, Donna Soave Nichols
Data On Gait Characteristics Of Four, Five, And Six Year Old Children Using Three Dimensional Video Motion Analysis, Donna Soave Nichols
Rehabilitation Sciences Theses & Dissertations
The purpose of this study resulted from a need to gather and analyze data on gait characteristics of normal children using the Peak Performance Technologies, Incorporated system, initiate a data base for the Motion Analysis Center at Old Dominion University and compare a computerized motion analysis system to studies using different methods. Fifteen children, aged four to six, were evaluated during gait using a video-based computerized motion analysis system manufactured by Peak Performance Technologies, Incorporated. The gait characteristics studied were stride length, cadence, angular displacements and angular velocities of the pelvis, hips, knees and ankles. The results showed that methods …

A two-part study was undertaken to investigate the effects of movement experiences on lower extremity function during impact activities. Group and single-subject performances were evaluated for a total of 12 male volunteers during landing (Study I) and running (Study II) activities. Standard biomechanical techniques were used to obtain kinematic (200 Hz) and kinetic (1000 Hz) data during soft, normal and stiff-knee landings (Study I) and for under, normal, and over-stride running (Study II). Performance trials were tested for normality, condition differences were documented and multiple regression models were computed to predict the first (F1) and second (F2) maximum vertical forces …

As a first step towards the integration of information on neural control, biomechanics and isolated muscle function, we constructed a three-dimensional musculo-skeletal model of the hind leg of the death-head cockroach Blaberus discoidalis. We tested the model by measuring the maximum force generated in vivo by the hind leg of the cockroach, the coxa-femur joint angle and the position of this leg during a behavior, wedging, that was likely to require maximum torque or moment production. The product of the maximum force of the leg and its moment arm yielded a measured coxa-femur joint moment for wedging behavior. The …
Is There A Difference In Cortical Representation Between Dominant And Non-Dominant Arm Muscles Of Elite Badminton Players?, Dylan J. Edwards
Is There A Difference In Cortical Representation Between Dominant And Non-Dominant Arm Muscles Of Elite Badminton Players?, Dylan J. Edwards
Theses : Honours
Training for sport involves the development of skill and coordination. The physiological changes associated with skill acquisition are complex and at present poorly understood. One of the areas in the central nervous system thought to be involved with skill acquisition is the cerebral motor cortex where localised areas are responsible for controlling specific muscle groups. Learning or improving a motor skill may require reorganisation of the cortical areas controlling relevant muscles to accommodate the new skill. To test this idea we studied a group of elite badminton players that were highly skilled in their dominant playing arm. Transcranial magnetic stimulation …
