Validation Of A Single Channel Eeg For The Athlete: A Machine Learning Protocol To Accurately Detect Sleep Stages, Kayla Thompson, Kamil Celoch, Frankie Pizzo, Ana I. Fins, Jaime Tartar

Journal for Sports Neuroscience

There is a large and growing movement towards the use of wearable technologies for sleep assessment. This trend is largely due to the desire for comfortable, burden free, and inexpensive technology. In tandem, given the competitive nature of professional athletes enduring high training load, sleep is often jeopardized which can result in adverse outcomes. Wearable devices hold the promise of increasing the ease of monitoring sleep in athletes which can inform health and recovery status, as well as aid performance optimization. However, wearable devices typically lack sufficient validity to assess sleep – and especially sleep stages. To address this concern, …

Hasselfeld Ms, Violet T. Schramm, Angelo J. Colosimo Md, Aaron Kuehn-Himmler At Ms, Gerald M. Holloway Ms Atc, Faniel Fosselman Do Mba, Jon Vincent, Nicole Giordano, Jon G. Divine Md Ms

Journal for Sports Neuroscience

Introduction.

Concussions are of significant concern for athletic trainers, and there is a critical need to objectively and safely allow an athlete to return to play. In sports the objective is return as safely and soon as possible. Exertion is a consideration regarding progressing an athlete back to play. The ability to exert in cardiovascular and strength and conditioning contexts are two critical steps in most return to play protocols. Being able to make objective recommendations is urgently needed, as trial and error leads to unnecessary risk of eliciting symptoms and/or causing setbacks.

Objective.

The object of this paper is …

Journal for Sports Neuroscience

Abstract.

Introduction

Sports related concussion, also considered mTBI, has remained in the public eye due to heightened fear concerning playing football and other collision based sports. Concussion prevention, as well as rehabilitating the brain after a concussion, is a high priority for many sports medical practitioners as well as for athletes. For these reasons, researchers associated with the American Athletic Conference (AAC) have surveyed concussion incidence in football. One of the AAC teams engaged in regular neurovisual training (NVT) and concluded this training program is associated with faster return to play post-injury in this observational cohort study.
