The Relationship Between Linear And Nonlinear Analysis On Activity Data, Katlyn J. Nimtz

UNO Student Research and Creative Activity Fair

Activity monitoring in older adults is a great way to predict disability without interfering in their daily life. We can analyze that data using linear and nonlinear analysis. While linear analysis measures the variation of activity during a specific period of time (i.e., mean, standard deviation), nonlinear analysis focuses on the evolution of activity over a period of time. Therefore, the purpose of this study was to observe the relationship between linear and nonlinear analysis of activity data obtained by activity monitoring in older adults. Eight participants wore an activity monitor around their waist for seven days. Linear analysis was …

Effect Of The Usage Of Handrails On Gait Dynamics In People With Parkinson's Disease, Daniel Jaravata, Danish Bhatti, Vivien Marmelat

The purpose of this project is to determine if increasing body stability during handrails-use walking on a treadmill will increase the complexity of gait variability in patients with Parkinsons disease (PD). In young healthy participants, stride time-series of walking presents a pattern of complex variability, but this complexity critically decreases in patients with PD. Complexity is defined as an optimal state between too much regularity and too much irregularity, allowing the locomotor system to maintain robust performances while being able to adapt to perturbations. A possible explanation is that the decrease in complexity results from increased control mechanisms to avoid …

With findings that the 6MWT is more efficient than the original 12-minute walk test (12MWT), perhaps it can be evident that even the 6MWT can be shortened to examine its effects in a shorter duration that can be more beneficial to the participant. The objective of this study is to examine the outcomes of each minute throughout the 6MWT trials and to see if functional measures can …
