Effects Of Added Vestibular Noise On Blindfolded Locomotor Veering, Russell J. Carmichael, Allison Sam, Philip K. Schot Phd
Effects Of Added Vestibular Noise On Blindfolded Locomotor Veering, Russell J. Carmichael, Allison Sam, Philip K. Schot Phd
International Journal of Undergraduate Research and Creative Activities
BACKGROUND: Nearly every fundamentally healthy human, regardless of fitness, age, or gender is incapable of walking in a perfectly straight line when visual information is removed. This is known as veering. Many different potential causes have been examined, but the most persuasive explanation is that without visual input, sensory interference (or noise) accumulates and causes random motor output errors. OBJECTIVE: The aim of this study was to examine veering behavior during blindfolded walking when added vestibular noise (vibration) was applied to the skull at select locations. METHODS: A handheld massager attached at the top of the head or over one …
A Comparison Of Teres Minor And Infraspinatus Muscle Activation In The Prone Position, Masaaki Tsuruike, Todd S. Ellenbecker
A Comparison Of Teres Minor And Infraspinatus Muscle Activation In The Prone Position, Masaaki Tsuruike, Todd S. Ellenbecker
Faculty Research, Scholarly, and Creative Activity
Background
The electromyography (EMG) activity of the teres minor (TMi) and infraspinatus (IS) muscle has been demonstrated to vary depending on the arm position, such as in the coronal or scapular position, during intervention exercises. This may be reflected by different EMG activities demonstrated between the TMi and IS muscle during the acceleration and deceleration phases of the pitching motion. Tenderness in the scapular attachment site of the TMi muscle is often seen in baseball pitchers after pitching but not the attachment site of the IS muscle. However, few studies have investigated an interaction between TMi and IS muscle activity …
A Time-Course Characterization Of Muscle Function And Mitochondrial Markers During Colorectal Cancer-Induced Cachexia In Tumor-Bearing Male Mice, Ana Cabrera Ayuso
A Time-Course Characterization Of Muscle Function And Mitochondrial Markers During Colorectal Cancer-Induced Cachexia In Tumor-Bearing Male Mice, Ana Cabrera Ayuso
Graduate Theses and Dissertations
Cachexia is a multisystemic and multifactorial syndrome prevalent in cancer patients. It is clinically defined by involuntary loss of >5% weight in a six-month window, despite nutritional interventions. A negative energy balance characterizes cancer cachexia (CC), it is associated with weakness and fatigue in skeletal muscle. Impaired muscle function is associated with lower quality of life in cancer patients. Defects in mitochondrial function are strongly associated with muscle wasting. This study explored muscular contractile function and mitochondrial quality control (MQC) markers in soleus, gastrocnemius, and tibialis anterior (TA) muscles of C26-induced male tumor-bearing mice during a 25-day time course. It …
Electromyography Activity Of The Teres Minor Muscle With Varying Positions Of Horizontal Abduction In The Quadruped Position, Masaaki Tsuruike, Todd S. Ellenbecker, Connor Lauffenburger
Electromyography Activity Of The Teres Minor Muscle With Varying Positions Of Horizontal Abduction In The Quadruped Position, Masaaki Tsuruike, Todd S. Ellenbecker, Connor Lauffenburger
Faculty Research, Scholarly, and Creative Activity
Background
The teres minor (TMi) muscle exposed relatively high activity during the acceleration and deceleration phases of the throwing motion, compared with the infraspinatus muscle. However, few studies have identified TMi muscle activity in intervention exercises. The purpose of this study was to investigate TMi muscle activities in different horizontal adduction positions in the quadruped horizontal abduction exercise. This study hypothesized that TMi muscle activity would differ in response to resistance application across different horizontal adduction positions.
Materials and methods
Nineteen collegiate baseball players volunteered their participation. Raw electromyography activity of the TMi muscle along with 7 different muscles attached …
Comparing Knee Joint Mechanics Across Phases Of The Menstrual Cycle, Bethany Kilpatrick
Comparing Knee Joint Mechanics Across Phases Of The Menstrual Cycle, Bethany Kilpatrick
Cal Poly Humboldt theses and projects
Anterior cruciate ligament (ACL) injuries are among the most commonly occurring knee injury. Compared to men in the same sports, females are two to eight times at higher risk for ACL injury. Research suggests that hormone fluctuations across the menstrual cycle (MC) play a crucial role in ACL injuries due to their effect on tendons and ligament's mechanical properties. PURPOSE: To examine knee joint laxity during dynamic movements across three-time points of the MC. METHODS: Seven young, healthy females with regular MCs performed three jump-landing tasks (double leg depth jump, single-leg lateral jump, and single-leg forward jump) across the early-follicular, …
The Effectiveness Of Using Video Modeling Techniques To Improve Motor Skills For Preschool Children With Autism Spectrum Disorders, Atya Abdullah Hadadi
The Effectiveness Of Using Video Modeling Techniques To Improve Motor Skills For Preschool Children With Autism Spectrum Disorders, Atya Abdullah Hadadi
Graduate Theses and Dissertations
Beside the main syndromes of socialization and communication for individuals with autism spectrum disorders, they also have impairments in motor skills, such as ball skills (catching and throwing) and postural stability (standing and walking balance). The main objective of this dissertation is to improve motor skills for preschooler children with ASD through use of video-modeling techniques. A secondary objective of this research was to find a correlation between the development and improvement of ball skills and balance tasks. Twenty-six children with ASD were divided into two groups. Twenty-six children with ASD from 3-5 years old participated in two groups: one …

Ya Ching Hung EdD. and Aryeh Spingarn EP-C, CSCS, EIM-Level 2 Queens College, City University of New York Department of Family, Nutrition, and Exercise Sciences, Changes in Reach to Eat Movement Control After Intensive Training for Children with Unilateral Cerebral Palsy. Purpose: The current study compares the effects of an intervention on children with Congenital Hemiplegia during a simple eating task using kinematic analyses. Previous studies looked at simple bimanual tasks such as opening a drawer; no studies examined the effects of intensive training on unimanual reach, grasp, and eat movement control. Methods: 20 children with Unilateral Spastic Cerebral Palsy …
Estimates Of Persistent Inward Current Decline In Human Soleus Motor Units During Fatigue, Kirby Mendes
Estimates Of Persistent Inward Current Decline In Human Soleus Motor Units During Fatigue, Kirby Mendes
Theses and Dissertations (Comprehensive)
Fatigue is defined as any exercise induced reduction in strength or power, and can be attributed to central and peripheral components. Many central and peripheral mechanisms have been extensively studied, but few studies have looked at the changes in the intrinsic properties of motor neurons and their contribution to fatigue. Persistent inward current (PIC) is an important intrinsic property of motor neurons responsible for setting a large increase in the gain of motor output and may contribute to fatigue. Inhibitory inputs such as reciprocal inhibition (RI) have been shown to turn off PICs and reducing the gain of output. PIC …
