Modelling Muscle Activation Using Emg Signal, Mercy U. Okonna
Modelling Muscle Activation Using Emg Signal, Mercy U. Okonna
College of Graduate Studies: Theses & Dissertations
(EMG) is a method for measuring muscle activity by an electrical signal, and is useful in studying motor control, postural control, and in physical therapy. A current research topic is creating an algorithm that can use the EMG signal to reliably classify a muscle as active or inactive. This thesis presents a classification algorithm for leg muscles with a single activation spike while walking. Time is rescaled into steps, which are identified using data from cameras measuring joint angles while walking. The algorithm is based on moving averages and a convex combination of mean signal strength in active and inactive …
Differential Effects Of Reduced Foot Sole Sensitivity And Nerve Conduction Velocity On Postural Control And Functional Gait, Kelsey D. Lewis
Differential Effects Of Reduced Foot Sole Sensitivity And Nerve Conduction Velocity On Postural Control And Functional Gait, Kelsey D. Lewis
College of Graduate Studies: Theses & Dissertations
INTRODUCTION: Peripheral neuropathy is characterized by a loss of foot sole sensitivity and slowed nerve conduction velocity. Individuals with peripheral neuropathy have decreased postural control ability and functional gait performance. No research was found that differentiated the effects of the main symptoms of peripheral neuropathy on postural control and functional gait. PURPOSE: The purpose of this study was to assess the differential effects of reduced foot sole sensitivity and slowed nerve conduction velocity on postural control and functional gait. METHODS: Two main clinical symptoms, H-index and foot sole sensitivity were evaluated among 35 participants. Outcome variables are the center of …
Baseline Postural Control Measures: An Indicator For Increased Injury Frequency Following Sports Related Concussion, Emily Belson
Baseline Postural Control Measures: An Indicator For Increased Injury Frequency Following Sports Related Concussion, Emily Belson
College of Graduate Studies: Theses & Dissertations
INTRODUCTION: An increase in acute lower extremity (LE) injuries have been observed in athletes following sports-related concussion.1, 2, 3 It has been suggested that lingering postural control deficits as a result of concussive injury, may play a role in the increased prevalence of injury.1 PURPOSE: To investigate the relationship between baseline postural control metrics (Root Mean Square; Peak Excursion Velocity; Sample Entropy) and acute LE injury frequency in NCAA Division I student athletes (SA) with a previous history of concussion. METHODS: Eighty-four NCAA Division I SA were selected from a single university, 42 SA with a previous history …
