Patients With Peripheral Arterial Disease Exhibit Reduced Joint Powers Compared To Velocity-Matched Controls, Shane Wurdeman, Panagiotis Koutakis, Sara Myers, Jason Johanning, Iraklis Pipinos, Nicholas Stergiou

Journal Articles

Previous studies have shown major deficits in gait for individuals with peripheral arterial disease before and after the onset of pain. However, these studies did not have subjects ambulate at similar velocities and potential exists that the differences in joint powers may have been due to differences in walking velocity. The purpose of this study was to examine the joint moments and powers of peripheral arterial disease limbs for subjects walking at similar self-selected walking velocities as healthy controls prior to onset of any symptoms. Results revealed peripheral arterial disease patients have reduced peak hip power absorption in midstance ( …

Mediating And Moderating Effects On The Association Between Vision Loss And Depression Among An Older Population, Terry L. Stone, Jonathan Bruce Santo, Walter Wittich

Psychology Faculty Publications

The purpose of this study was to gain a more holistic view of the association between depression and visual functioning by examining possible mediating and moderating factors. Previous research has established a linkage between low life satisfaction and coping skills and depressive symptoms. Results of this study contribute to this literature by indicating that life satisfaction partially mediates the relationship between visual functioning and depression. Furthermore, a significant coping by visual functioning interaction was discovered, revealing that among this sample, visual impairment is associated with higher levels of depression among individuals with low coping skills; however, little effect was found …

The Influence Of Cognitive-Perceptual Variables On Patterns Of Change Over Time In Rural Midlife And Older Women’S Healthy Eating, Bernice C. Yates, Carol H. Pullen, Jonathan Santo, Linda Boeckner, Patricia A. Hageman, Paul J. Dizona, Susan Noble Walker

Psychology Faculty Publications

Although studies demonstrate that dietary interventions for healthy adults can result in beneficial dietary changes, few studies examine when and how people change in response to these interventions, particularly in rural populations. The purpose of this study was to examine patterns of change over time in healthy eating behaviors in midlife and older women in response to a one-year health-promoting intervention, and to examine what predictors (perceived benefits, barriers, self-efficacy, and family support for healthy eating) influence the changes during the intervention and follow-up. Data for this secondary analysis were from the Wellness for Women community-based trial. Women (N …

Response To Chastin Et Al.: Analysis Of Nonlinear Patterns Of Activity, James T. Cavanaugh, Nicholas Stergiou

Journal Articles

We appreciate the thoughtful commentary by Chastin and colleagues regarding our recent article entitled “Nonlinear Analysis of Ambulatory Activity Patterns in Community-dwelling Older Adults.” (1) We fully agree with their observation that the application of nonlinear analytical tools to accelerometry data is an emerging area of research that shows potential for illuminating the complex nature of physical activity profiles. We also welcome the opportunity to discuss their concerns regarding (a) our application of detrended fluctuation analysis (DFA), entropy rate, and approximate entropy to natural activity data and (b) our narrow focus on stepping activity.

The Effect Of Virtual Reality On Gait Variability, Dimitrios Kastavelis, Mukul Mukherjee, Leslie M. Decker, Nikolaos Stergiou

Journal Articles

Optic Flow (OF) plays an important role in human locomotion and manipulation of OF characteristics can cause changes in locomotion patterns. The purpose of the study was to investigate the effect of the velocity of optic flow on the amount and structure of gait variability. Each subject underwent four conditions of treadmill walking at their self-selected pace. In three conditions the subjects walked in an endless virtual corridor, while a fourth control condition was also included. The three virtual conditions differed in the speed of the optic flow displayed as follows – same speed (OFn), faster (OFf), and slower (OFs) …

Attractor Divergence As A Metric For Assessing Walking Balance, Max J. Kurz, Katerina Markopoulou, Nikolaos Stergiou

Journal Articles

: Individuals with Parkinson's disease and the aged have a high prevalence of falls. Since an increase in the number of falls is associated with physical and psychological harm, it is prudent that biomechanical metrics be established that will accurately assess an individual's walking balance. In this investigation, we initially used a simple bipedal walking computer model to theoretically establish the relationship between attractor divergence and walking balance. The Lyapunov exponent was used to quantify the amount of divergence present in the walking attractor. Simulations from our model indicated that attractors that have a greater amount of divergence are more …

Variability Of Lower Extremity Joint Kinematics During Backward Walking In A Virtual Environment, Dimitrios Kastavelis, Mukul Mukherjee, Leslie M. Decker, Nikolaos Stergiou

Journal Articles

Backward walking (BW) shows significant differences with forward walking (FW) and these differences are potentially useful in rehabilitation. However the lack of visual cues makes BW risky. The purpose of this study was to investigate the effect of visual cues provided by a virtual environment on FW and BW on gait variability. Each subject underwent four conditions of treadmill walking at self-selected pace. The subjects walked backwards in three conditions and forwards in the fourth condition. A virtual corridor was displayed to the subjects in the FW condition (forward optic flow) and two of the backward conditions (forward and backward …

Nonlinear Analysis Of Ambulatory Activity Patterns In Community-Dwelling Older Adults, James T. Cavanaugh, Naomi Kochi, Nikolaos Stergiou

Journal Articles

Background The natural ambulatory activity patterns of older adults are not well understood. User-worn monitors illuminate patterns of ambulatory activity and generate data suitable for analysis using measures derived from nonlinear dynamics.

MethodsAmbulatory activity data were collected continuously from 157 community-dwelling older adults for 2 weeks. Participants were separated post hoc into groups based on the mean number of steps per day: highly active (steps ≥ 10,000), moderately active (5,000 ≤ steps < 10,000 steps), and inactive (steps

Results All groups displayed patterns of fluctuating step count values containing complex temporal structure. DFA, ER, and ApEn parameter values increased monotonically and significantly with increasing activity …

Infants Born Preterm Exhibit Different Patterns Of Center-Of-Pressure Movement Than Infants Born At Full Term, Stacey C. Dusing, Anastasia Kyvelidou, Vicki S. Mercer, Nikolaos Stergiou

Journal Articles

Background: Infants born preterm are at risk for developmental impairments related to postural control.

Objective: The purpose of this study was to determine whether infants born preterm and infants born at full term differed in postural control at 1 to 3 weeks after term age.

Design: This study included 17 infants born preterm (mean gestational age=31.9 weeks, range=25.0–34.6) and 15 infants born at full term (mean gestational age=38.9 weeks, range=37.3–40.6). All infants were without diagnosed neurological or genetic conditions.

Measurement: Center-of-pressure (COP) data were recorded at 5 Hz while each infant was positioned supine on a pressure-sensitive mat …

The First Anniversary: Stress, Well-Being, And Optimism In Older Widows, Mary E. Minton, Melody Hertzog, Cecilia R. Barron, Jeffrey French, Roni Reiter-Palmon

Psychology Faculty Publications

The first anniversary for older widows (n = 47) has been explored during Months 11, 12, and 13. Concurrent correlations show that optimism inversely correlates with psychological (intrusion and avoidance) stress as measured with the Impact of Event Scale (r = —.52 to —.66, p < .005) and positively correlates with well-being (physical: r = .36 to .46, p < .025; psychosocial: r = .58 to .72, p < .005; spiritual: r = .50 to .69, p < .005). Lagged correlation patterns suggest that higher levels of optimism at a given time are associated with higher life satisfaction and spiritual well-being at later times. Psychological stress is higher at Month 12 when compared to Month 13, t(43) = 2.54, p = .01, but not when compared to Month 11, t(43) = 1.49, p > .10. There are no significant differences in physiologic stress (salivary cortisol) or well-being during the first …
