Comparison Of Therapeutic Exercise Accuracy During Completion Of A Home Exercise Program Using The Exercise Tutor Versus A Written Home Exercise Program, James Flis, Riana Stanko, Megan Stang, Ann Reinthal, Deborah Espy

Undergraduate Research Posters 2014

Exercise is powerful in rehabilitation and prevention of disability; however, patient adherence to home exercises is difficult, learning new movements requires a great deal of practice, and incorrectly performed exercises are ineffective or even dangerous. We have developed a system comprised of a Kinect device with wearable inertial sensors to capture, record, and process the exerciser’s movement while concurrently providing targeted feedback to guide correct exercise completion. This pilot study allowed us to perform initial testing of this system, specifically, the effectiveness of this system in improving exercise accuracy, with and without the addition of inertial sensors to the Kinect …

Is Steering Practice Task Dependent?, Dale Lewis, Seyed Amirhossein Hosseini, Jacqueline Jenkins

A driving simulation experiment was conducted to examine the performance improvement of participants while conducting a lane keeping task and two lane changing tasks on a straight road. Forty-four participants, sixteen females and twenty-eight males, drove one of three driving conditions. The data was analyzed to test whether 1) practice is better than no practice; 2) practicing a less challenging but similar steering task is good practice for a more challenging steering task; and 3) practicing a more challenging but similar steering task is good practice for a less challenging steering task. The results indicate that practicing the more challenging …

Motor Output Structure In Targeted Aiming: A Mechanistic Model, Dale Lewis, Roger Young, Jeffrey Eder, Andrew B, Slifkin

Undergraduate Research Posters 2014

Studies using a variety of experimental tasks have established that when humans repeatedly produce an action, fluctuations in action output are highest at the lowest frequencies and fluctuation magnitude (power) systematically declines as frequency increases. Such time series structure is termed pink noise. However, the appearance of pink noise seems to be limited to tasks where action is executed in the absence of task-related feedback. A few studies have demonstrated that when action was executed in the presence of task-related feedback, power was evenly distributed across all spectral frequencies—i.e., white noise was revealed. Here, participants produced cyclical aiming movements under …

The elliptical cross trainer has become a popular a mode of exercise, but can only be used indoors. The StreetStrider was designed as an outdoor elliptical-bike. PURPOSE: The purpose of this study is to determine whether the elliptical or the StreetStrider was more enjoyable, and to compare the physiological variables for energy expenditure, heart rate (HR), VO2, and Rate of Perceived Exertion (RPE). METHODS: Thirty participants (15 male, 15 female, mean age=22±2) from Cleveland State University exercised for 20 minutes at 75% of their age predicted maximal heart rate on the StreetStrider and elliptical. Energy expenditure was measured with a …
