Examining The Learning Effects Of Live Streaming Video Game Instruction Over Twitch, Katherine Payne, Mark J. Keith, Ryan M. Schuetzler, Justin Scott Giboney

Information Systems and Quantitative Analysis Faculty Publications

Technology facilitates advances in learning and drives learning paradigms. One recent innovation is Twitch™, an online streaming platform often used for video game tutorials but also enables amateur online instruction (Hamilton, Garretson, & Kerne, 2014)). Twitch represents a unique learning paradigm that is not perfectly represented in previous technologies because of its “ground-up” evolution and the opportunity for novice instructors to educate mass audiences in real-time over the Internet while enabling interaction between teachers and learners and among learners. The purpose of this research is to empirically examine the efficacy of Twitch as a learning platform by manipulating each of …

Quantifying Static And Dynamic Stability Using Mobile Sensors, Mason Schleu

UNO Student Research and Creative Activity Fair

Balance disorders impact millions of people causing substantial impact on quality of life due to psychological and physical hardships associated with poor balance. However, a clinically relevant, low cost, self-service system in detecting such disorders does not exist. Previous research has shown the built in accelerometer and gyroscope sensors of a smart phone to be valid tools in detecting standing balance performance using traditional linear analysis, however, such a system has yet to be proven useful in detecting dynamic postural variability. Indeed, more quantitative methods than are typically used in clinical settings are necessary for early detection of poor postural …

Peak Vertical Ground Reaction Force & Stance Phase Time To Assess Post-Tka Interlimb Asymmetry, Abderrahman Ouattas

UNO Student Research and Creative Activity Fair

In the US, more than 500,000 TKA surgeries are performed annually, to which 97% of those are led by OA¹. Although knee pain is diminished post-TKA, unilateral efficiency and walking asymmetry is still unresolved several years after the surgery². In fact, within a minimum of 10 years after the primary TKA, almost 50% of patients undergo a secondary TKA on the contralateral limb due to OA progression³. The purpose of this study was to determine if post-Total Knee Arthroplasty peak vertical ground reaction force (pVGRF) asymmetry could be identified using stance phase time differences …

Acl Reconstruction Results In Alterations For Force Control Variability During Multidirectional Force Production, Amelia S. Lanier

UNO Student Research and Creative Activity Fair

After anterior cruciate ligament (ACL) rupture most will undergo reconstructive surgery. Within the first year after surgery 25% of patients will re-tear their ACL. Most of those injured attempt to return to sports which include running and cutting. The ability to produce appropriate ground reaction forces may be crucial for the successful return to sports without re-injury. Understanding stability of multidirectional ground reaction force (mGRF) production in healthy and ACL reconstructed (ACL-r) patients can lend insight to the high instance of re-injury. Typically, stability has been measured using linear analyses, but these analyses cannot capture the subtle time varying changes …

The Effects Of Walking Speed On Gait Propulsion When Wearing An Ankle-Foot Orthosis, Alli Kalina

UNO Student Research and Creative Activity Fair

Peripheral artery disease (PAD) is a cardiovascular disease that results from blockage of one or more arteries in the lower extremity. Often, patients with PAD have reduced ability to push off with the foot at the end of the gait cycle. When walking, the ankle contributes the majority of the power to propel the body into the next step. An ankle-foot orthosis (AFO) is a device that aids in ankle propulsion by increasing the energy return, thus decreasing the ankle deficit in pathological individuals. The purpose is to investigate the effect of walking speed on ankle propulsion during walking. Subjects …
