Yoga practice has been minimally studied for its effects on breast cancer related lymphedema (BCRL). The purpose of this study was to determine the effect of yoga on arm volume, quality of life (QOL), self-reported arm function, and hand grip strength in women with BCRL. Six women with BCRL participated in modified Hatha yoga 3×/week for 8 weeks. Compression sleeves were worn during yoga sessions. Arm volume, QOL, self-reported arm function, and hand grip strength were measured at …

Kir Channel Activation Contributes To Onset And Steady-State Exercise Hyperemia In Humans, Anne R. Crecelius, Gary J. Luckasen, Dennis G. Larson, Frank A. Dinenno

Health and Sport Science Faculty Publications

We tested the hypothesis that activation of inwardly rectifying potassium (K_IR) channels and Na⁺-K⁺-ATPase, two pathways that lead to hyperpolarization of vascular cells, contributes to both the onset and steady-state hyperemic response to exercise. We also determined whether after inhibiting these pathways nitric oxide (NO) and prostaglandins (PGs) are involved in the hyperemic response. Forearm blood flow (FBF; Doppler ultrasound) was determined during rhythmic handgrip exercise at 10% maximal voluntary contraction for 5 min in the following conditions: control [saline; trial 1 (T1)]; with combined inhibition of K_IR channels and Na …

The Quadmill: Effects Of Eccentric Training Vs. Concentric Training On Lower Extremity Power And Anaerobic Capacity 2014., John Crosby

Participants were 44 undergraduate college students (24 Male 20 Female) Design: participants placed into three equal groups (Quadmill^TM, Lifting, Control). The two experimental groups (Quadmill^TM and Lifting) underwent …

Comparison Of Functional Network Connectivity For Passive-Listening And Active-Response Narrative Comprehension In Adolescents, Yingying Wang, Scott K. Holland

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Comprehension of narrative stories plays an important role in the development of language skills. In this study, we compared brain activity elicited by a passive-listening version and an active-response (AR) version of a narrative comprehension task by using independent component (IC) analysis on functional magnetic resonance imaging data from 21 adolescents (ages 14–18 years). Furthermore, we explored differences in functional network connectivity engaged by two versions of the task and investigated the relationship between the online response time and the strength of connectivity between each pair of ICs. Despite similar brain region involvements in auditory, temporoparietal, and frontoparietal language networks …

The Importance Of Managing Psychosocial Health: A Case Study, Mary Insana Fisher, Harold L. Merriman

Physical Therapy Faculty Publications

Managing the physical aspects of lymphedema requires an individual to be committed to daily treatment of this chronic condition. Performing manual lymph drainage, using compression bandaging or compression garments, exercising, and caring for the skin all take time and a high level of dedication. This commitment to self-care can be emotionally and psychologically exhausting.

When coupled with other emotional stressors in a patient’s life, successful treatment of lymphedema is challenging. We present a case demonstrating how the physical and psychological aspects of care interplay, and, when well-managed, can positively affect the outcome.

Influence Of Tendon Tears On Ultrasound Echo Intensity In Response To Loading, Kayt E. Frisch, David Marcu, Geoffrey S. Baer, Darryl G. Thelen, Ray Vanderby

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Acoustoelastic (AE) ultrasound image analysis is a promising non-invasive approach that uses load-dependent echo intensity changes to characterize stiffness of tendinous tissue. The purpose of this study was to investigate whether AE can detect localized changes in tendon stiffness due to partial and full-thickness tendon tears. Ovine infraspinatus tendons with different levels of damage (Intact, 33%, 66% and full thickness cuts initiated on the articular and bursal sides) were cyclically loaded in a mechanical testing system while cine ultrasound images were recorded. The load-induced changes in echo intensity on the bursal and articular side of the tendon were determined. Consistent …

The Influence Of Partial And Full Thickness Tears On Infraspinatus Tendon Strain Patterns, Kayt E. Frisch, David Marcu, Geoffrey S. Baer, Darryl G. Thelen, Ray Vanderby

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Tears on the bursal and articular sides of the rotator cuff tendons are known to behave differently and strain is thought to play a role in this difference. This study investigates the effect of tear location on the changes in three strain measurements (grip-to-grip, insertion, and mid-substance tissue) in a sheep infraspinatus tendon model during axial loading. We introduced a 14mm wide defect near the insertion from either the articular or bursal side of the tendon to three depths (3 mm, 7mm & full) progressively. For each condition, tendons were sinusoidally stretched (4% at 0.5 Hz) while insertion and midsubstance …

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Of all sports, football accounts for the highest incidence of concussion in the US due to the large number of athletes participating and the nature of the sport. While there is general agreement that concussion incidence can be reduced through rule changes and teaching proper tackling technique, there remains debate as to whether helmet design may also reduce the incidence of concussion. A retrospective analysis was performed of head impact data collected from 1833 collegiate football players who were instrumented with helmet-mounted accelerometer arrays for games and practices. Data were collected between 2005 and 2010 from 8 collegiate football teams: …

Winning And Losing: Differences In Reward And Punishment Sensitivity Between Smokers And Nonsmokers, Laura E. Martin, Lisa S. Cox, William M. Brooks, Cary R. Savage

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Background: Smokers show increased brain activation in reward processing regions in response to smoking-related cues, yet few studies have examined secondary rewards not associated with smoking (i.e., money). Inconsistencies exist in the studies that do examine secondary rewards with some studies showing increased brain activation in reward processing brain regions, while others show decreased activation or no difference in activation between smokers and nonsmokers. Aims: The goal of the current study is to see if smokers process the evaluation and delivery of equally salient real world rewards similarly or differently than nonsmokers. Methods: The current study employed functional magnetic resonance …

Alterations And Specifications Of Excess Post-Exercise Oxygen Consumption: A Review, Genevieve Kocoloski, Anne R. Crecelius

Health and Sport Science Faculty Publications

This review describes oxygen consumption, both in terms of a goal of weight management and aerobic training. It introduces excess postexercise oxygen consumption (EPOC) and the benefits that can come from it. EPOC can aid in weight management as a means to continue to expend energy even after exercise has ceased. This review also discusses the many determinants of EPOC and analyzes the effects of various conditions on the elevated consumption. Such conditions include duration and intensity of exercise, training status, and supplementation. Later discussed are the possible underlying mechanisms and how they are responsible for EPOC. Although they have …

Trunk Coordination In Dancers And Non-Dancers, Danielle N. Jarvis, Jo Armour Smith, Kornelia Kulig

Physical Therapy Faculty Articles and Research

Variability, or how a task changes across trials, may reveal differences between athletes of differing skill levels. The purpose of this study was to examine trunk and lower extremity (LE) single joint kinematic variability and inter-segmental coordination variability in dancers and non-dancers during bipedal vertical dance jumps (sautés). Twenty healthy females, ten with no formal dance training and ten professional dancers, performed 20 consecutive sautés. Single joint kinematic variability was assessed using mean standard deviation of angular displacement, and inter-segmental coordination variability was assessed using angular deviation of the coupling angle between segments. Within the context of the standard error …

Neuromuscular Factors Affecting Stretch-Induced Torque Loss, Gabriel Siqueira Trajano

Theses: Doctorates and Masters

The mechanisms underpinning the immediate torque loss induced by acute, static muscle stretching are still not clear. The current research was designed to examine the neuromuscular factors influencing this torque loss. In Study 1, the contributions of central versus peripheral factors to the stretch-induced torque loss were investigated. Measures of central drive, including the EMG amplitude normalised to the muscle compound action potential amplitude (EMG:M), percent voluntary activation (%VA) and first volitional wave amplitude (V:M), and measures of peripheral function, including the twitch peak torque and 20:80 Hz tetanic torque ratio were made before, and immediately and 15 min after …

Pain Assessment And Possible Mechanism Of Delayed Onset Muscle Soreness, Wing Yin Lau

Theses: Doctorates and Masters

Muscle pain is felt during exercise or daily activities for several days after performing unaccustomed exercise, which is referred to as delayed onset muscle soreness (DOMS). Many people experience DOMS, but its underlying mechanisms are not fully understood. One of the challenges in the investigation of DOMS is its subjective nature, which makes the assessment ambiguous, thus establishing a standardised protocol is necessary. The present thesis scrutinised muscle pain assessments (Study 1, Study 2), developed a new assessment of muscle pain focusing on muscle fascia (Study 3), and investigated why DOMS is reduced after the second than the first bout …
