The Relationship Between Linear And Nonlinear Analysis On Activity Data, Katlyn J. Nimtz 2018 University of Nebraska at Omaha

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

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 ...


A Novel Task To Decrease Step Width Variability In Older Adults, Andreas Skiadopoulos, Katherine Allen, Nicholas Stergiou 2018 University of Nebraska at Omaha

A Novel Task To Decrease Step Width Variability In Older Adults, Andreas Skiadopoulos, Katherine Allen, Nicholas Stergiou

Student Research and Creative Activity Fair

Walking is the most common fall-related activity among older adults. Also, older adults experience greater step width variability when walking. Importantly, increased step width variability during walking has been found to be a strong predictor of fall risk and incidence. Therefore, an intervention for reducing increased step width variability may consequently reduce fall risk for older adults. In the present study, we proposed that lateral stepping training program improve walking in older adults by reducing the increased step width variability to normal values. Therefore, the purpose of the present study is to determine the effect of a six-week lateral stepping ...

Department of Biomechanics, University of Nebraska at Omaha, Omaha, NE 68182

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 be ...

Kinematic And Kinetic Indicators Of Sit-To-Stand, Catherine A. Stevermer, Jason C. Gillette 2017 Des Moines University - Osteopathic Medical Center

Kinematic And Kinetic Indicators Of Sit-To-Stand, Catherine A. Stevermer, Jason C. Gillette

Jason C Gillette

Variation in the timing indicators separating sit-to-stand (STS) into movement phases complicates both research comparisons and clinical applications. The purpose of this study was to use kinetic reference standards to identify accurate kinematic and kinetic indicators for STS movement analysis such that consistent indicators might be used for STS from varied initial postures. Healthy adults performed STS using 4 foot placements: foot-neutral, foot-back, right-staggered, and left-staggered. Kinetic and kinematic data were collected from force platforms and an 8-camera video system. Initiation, seat-off, vertical posture, and termination were detected with 5% start and 7.5% end thresholds for changes in kinetic ...

Muscle Activity Amplitudes And Co-Contraction During Stair Ambulation Following Anterior Cruciate Ligament Reconstruction, Michelle Hall, Catherine A. Stevermer, Jason C. Gillette

Jason C Gillette

The purpose of this study was to compare muscle activity amplitudes and co-contraction in those with anterior cruciate ligament (ACL) reconstruction to healthy controls during stair negotiation. Eighteen participants with unilateral ACL reconstruction and 17 healthy controls performed stair ascent and descent while surface electromyography was recorded from knee and hip musculature. During stair ascent, the ACL group displayed higher gluteus maximus activity (1–50% stance, p = 0.02), higher vastus lateralis:biceps femoris co-contraction (51–100% stance, p = 0.01), and higher vastus lateralis:vastus medialis co-contraction (51–100% stance, p = 0.05). During stair descent, the ACL group ...

Prognosis Of Anterior Cruciate Ligament Reconstruction: A Data-Driven Approach, Abhijit Chandra, Oliva Kar, Kuan Chuen Wu, Michelle Hall, Jason C. Gillette

Jason C Gillette

Individuals who suffer anterior cruciate ligament (ACL) injury are at higher risk of developing knee osteoarthritis (OA) and almost 50% display symptoms 10–20 years post injury. Anterior cruciate ligament reconstruction (ACLR) often does not protect against knee OA development. Accordingly, a multi-scale formulation for data-driven prognosis (DDP) of post-ACLR is developed. Unlike traditional predictive strategies that require controlled off-line measurements or ‘training’ for determination of constitutive parameters to derive the transitional statistics, the proposed DDP algorithm relies solely on in situmeasurements. The proposed DDP scheme is capable of predicting onset of instabilities. As the need for off-line testing ...


The Effects Of Postseason Break On Knee Biomechanics And Lower Extremity Emg In A Stop-Jump Task: Implications For Acl Injury, Boyi Dai, Christopher J. Sorensen, Timothy R. Derrick, Jason C. Gillette 2017 University of Wyoming

The Effects Of Postseason Break On Knee Biomechanics And Lower Extremity Emg In A Stop-Jump Task: Implications For Acl Injury, Boyi Dai, Christopher J. Sorensen, Timothy R. Derrick, Jason C. Gillette

Timothy R Derrick

The effects of training on biomechanical risk factors for anterior cruciate ligament (ACL) injuries have been investigated, but the effects of detraining have received little attention. The purpose of this study was to evaluate the effects of a one-month postseason break on knee biomechanics and lower extremity electromyography (EMG) during a stop-jump task. A postseason break is the phase between two seasons when no regular training routines are performed. Twelve NCAA female volleyball players participated in two stop-jump tests before and after the postseason break. Knee kinematics, kinetics, quadriceps EMG, and hamstring EMG were assessed. After one month of postseason ...


Effects Of Direction Time Constraints And Walking Speed On Turn Strategies And Gait Adaptations In Healthy Older And Young Adults, Dennis Torre 2017 Seton Hall University

Effects Of Direction Time Constraints And Walking Speed On Turn Strategies And Gait Adaptations In Healthy Older And Young Adults, Dennis Torre

Seton Hall University Dissertations and Theses (ETDs)

Hip fractures can be life-threatening, debilitating, and costly. The odds for hip fracture increases from impact of sideways falls. While turning has been strongly associated with hip fracture & sideways falls, the distinction between the risks for walking-turns as opposed to low-velocity in-place turning is not clear. The present study sought to fill a gap as previous research had not compared walking-turn performance in young & healthy older adults at low-fall risk within the same study and response-conditions of speed interacting with direction-cue time constraints. Spatial-temporal variables representative of AP braking/propulsion (i.e. stride-length & speed) & ML stability (left/right H-H BOS) were collected with the Gaitrite upon approach of a turning zone whose entrance width was just 73 cm; and turn-strategy categorical data for stable wide-BOS step-turns, biomechanically challenging narrow-BOS spin-turns, and combined subtypes of mixed-turns either of the “extra-step” variety representative of an AP stability/braking issue or “small-amplitude” variety representative of a ML stability/balance issue were captured on video. Mixed-ANOVA of gait measures for AP propulsion/braking revealed no age-group differences in speed despite a trend for less of a fast-pace increase in elderly stride-length, yet similar anticipatory ...

Biology Faculty Publications

We present unifying rules governing the efficient locomotion of swimming fish and marine mammals. Using scaling and dimensional analysis, supported by new experimental data, we show that efficient locomotion occurs when the values of the Strouhal (St) number St(=f A/U) and A∗(=A/L), two nondimensional numbers that relate forward speed U, tail-beat amplitude A, tail-beat frequency f , and the length of the swimmer L are bound to the tight ranges of 0.2–0.4 and 0.1–0.3, respectively. The tight range of 0.2–0.4 for the St number has previously been associated ...


Analysis Of Human Movement Patterns During Endurance Running, Joshua Paul Bailey 2017 University of Nevada, Las Vegas

Analysis Of Human Movement Patterns During Endurance Running, Joshua Paul Bailey

UNLV Theses, Dissertations, Professional Papers, and Capstones

Endurance running and participation in racing events has flourished over the last decade. Recreational runners enter the training period for an upcoming race at differing levels of fitness and training. As individuals sign-up for the race, they typically follow the commitment with an increase in training load. The increases in training load are accomplished through a combination of increasing mileage, or duration of running, and running intensity through increase velocity. These increases are theoretically being applied in a progressive overload principle, where the musculoskeletal system has time to adapt to the breakdown provided from the previous training session. Progressive overload ...


Optimization Of Prosthetic Hands: Utilizing Modularity To Improve Grip Force, Grasp, And Versatility, Jordan William Harris 2017 University of Nevada, Las Vegas

Optimization Of Prosthetic Hands: Utilizing Modularity To Improve Grip Force, Grasp, And Versatility, Jordan William Harris

UNLV Theses, Dissertations, Professional Papers, and Capstones

It has been demonstrated that although many varieties of upper limb prosthetics exist, commercially available prosthetics are outdated and unsatisfactory. Ineffectiveness and limitations have led to some prosthesis wearers having to own multiple devices, whereas others have given up on them entirely. Even though ample research has been conducted to design and test new hand designs, the industry appears to rest in an overall stagnated state.

It was proposed here, that one problem with prosthetic research is an excess of variables involved in testing, and therefore the improper application of the scientific method. It seems that each time a research ...
