Contributions Of Vision To The Neuromotor Control And Biomechanics Of Depth Jumping, Kenneth Harrison
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
PURPOSE: To investigate the role of vision during depth jump movements and further explore effects of stroboscopic goggles on the motor control of landing. METHODS: Ground reaction force (GRF), rate of force development (RFD), and lower limb surface electromyography measurements were collected on 20 participants (11 male 9 female) across 6 trials of depth jumping (0.51 m) in each of two visual conditions (full vision vs stroboscopic vision). Root-mean-square was estimated from EMG signals that were reduced to specific time-bins (150ms pre touchdown, 30-60ms, 60-85 ms, and 85-120 ms post touchdown). Main effects of and interactions between visual condition and …

As our bodies are exposed to whole-body vibration inertial and strain sensitive sensory receptors throughout our body are activated. The information relayed from these receptors to the central nervous system and brain is used to analyze our environment and coordinate movement. The aim of this study was to investigate whether extended duration whole-body vibration influences sensory adaptation and coordinated movement, specifically our joint position acuity immediately following vibration exposure. Twenty-five adults completed a between ankle joint matching task before and immediately following a 20-minute whole-body vibration session and a control session of 20 minutes of standing near, but not on …

Motor Affordance For Grasping A Safety Handle, Doug W. Mcdannald
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Observation of objects in our environment can potentiate movement, a fact reflected by increased activity in motor cortical networks when participants simply view a graspable object. This suggests that specific areas in the motor cortex play an important role in processing visual information to rapidly determine an appropriate action. The present study was conducted to test if visual access to a wall-mounted safety handle results in activation of motor cortical networks. We hypothesized that the hand area of the primary motor cortex would be facilitated shortly after visual access to a safety handle versus when no handle was visible. To …
