History Of Concussion And Current Functional Movement Screen Scores In A Collegiate Recreational Population, Jordan M. Dorrien
History Of Concussion And Current Functional Movement Screen Scores In A Collegiate Recreational Population, Jordan M. Dorrien
Electronic Theses and Dissertations
Introduction: 1.6-3.8 million concussions occur annually related to sport.1 Although neurometabolic alterations in the brain last 7-10 days following a concussion, an increased Cortical Silent Period (CSP) has been found to persist after 19 months.2,3 Further, movement impairments have been noted years after injury.4 The Functional Movement Screen (FMS) assesses mobility and stability in the body.5 The purpose of this study was to assess if FMS scores correlate to history of a concussion in healthy college club sport participants. Methods: Health history and FMS score were collected on 55 participants (38 male, …
Impedance Changes In Biceps Brachii Due To Isometric Contractions And Muscle Fatigue Using Electrical Impedance Myography (Eim), Travis Orth
Electronic Theses and Dissertations
Electrical impedance myography (EIM) is a non-invasive technique used to evaluate neuromuscular conditions by using a quantitative parameter called impedance (Z). It relies upon the application and measurement of high-frequency, low-intensity electrical current imbedded over a localized muscle to determine its opposition to current flow. In brevity, impedance determines the resistance of muscle fibers due to changes in muscle composition. The objective of this thesis was to establish a relationship between muscles at rest and during isometric contractions at various force levels(25%, 50%, and 100% of maximum voluntary contraction) of the biceps brachii over a multifrequency spectrum. Impedance measurements due …
