Shoulder Pain, Functional Status, and Health-Related Quality of Life after Head and Neck Cancer Surgery
(2013-12) Wang, Hsiao-Lan; Keck, Juanita F.; Weaver, Michael T.; Mikesky, Alan; Bunnell, Karen; Buelow, Janice M; Rawl, Susan M.
Head and neck cancer (HNC) patients experience treatment-related complications that may interfere with health-related quality of life (HRQOL). The purpose of this study was to describe the symptom experience (shoulder pain) and functional status factors that are related to global and domain-specific HRQOL at one month after HNC surgery. In this exploratory study, we examined 29 patients. The outcome variables included global HRQOL as well as physical, functional, emotional, and social well-being. Symptom experience and functional status factors were the independent variables. In the symptom experience variables, shoulder pain distress was negatively associated with physical well-being (R2 = 0.24). Among the functional status variables, eating impairment was negatively related to global HRQOL (R2 = 0.18) and physical well-being (R2 = 0.21). Speaking impairment and impaired body image explained a large amount of the variance in functional well-being (R2 = 0.45). This study provided initial results regarding symptom experience and functional status factors related to poor HRQOL in the early postoperative period for HNC patients.
An Analysis of Future Coaches’ Emerging Dispositions on Social Justice: The Wooden Effect
(2014-02) Culp, Brian
This qualitative study explored the extent to which an archetype presented through a non-fiction text could impact aspiring coaches' (AC's) dispositions regarding social justice. Forty-three aspiring coaches at a Midwestern university enrolled in a foundations class that presented issues related to inequity were studied. Analysis of student journals indicated changes in AC's philosophies regarding social justice, an appreciation for the perspectives of underrepresented groups and emergent critical perspectives when examining sport processes. Results of the study imply that a focus on democratic education and constructivism in coaching preparation programs may be of benefit. A means by which praxis of this nature can be realized for future professionals is presented using Giddens' structuration theory.
Promoting Successful Aging through Competitive Sports Participation Insights from Older Adults
(2013-01) Heo, Jinmoo; Culp, Brian; Yamada, Naoko; Won, Youngshin
In this study we explored the experience of competing in the Senior Games and the resultant contributions to the successful aging of older adults. We used in-depth interviews with older adults who participated in the National Senior Games. Analysis of the data produced five central themes: (a) perseverance, (b) career development and significant effort, (c) personal and social benefits, (d) unique ethos, and (e) identification as a senior athlete. We found that participating in the Senior Games as a form of serious leisure enhanced the well-being of older adults and could be utilized as a means by which to maintain a healthy lifestyle.
Reliability of pain intensity clamping using response-dependent thermal stimulation in healthy volunteers
(Springer (Biomed Central Ltd.), 2015) Cruz-Almeida, Yenisel; Naugle, Kelly M.; Vierck, Charles J.; Fillingim, Roger B.; Riley, Joseph L.; Department of Kinesiology, School of Physical Education and Tourism Management
BACKGROUND: Pain intensity clamping uses the REsponse-Dependent Stimulation (REDSTIM) methodology to automatically adjust stimulus intensity to maintain a desired pain rating set-point which is continuously monitored from a subject's real-time pain ratings. REDSTIM blinds subjects regarding the pain intensity set-point, supporting its use for assessing intervention efficacy. By maintaining the pain intensity at a constant level, a potential decrease in pain sensitivity can be detected by an increase in thermode temperature (unknown to the subject) and not by pain ratings alone. Further, previously described sensitizing and desensitizing trends within REDSTIM provide a novel insight into human pain mechanisms overcoming limitations of conventional testing methods. The purpose of the present study was to assess the test-retest reliability of pain intensity clamping using REDSTIM during three separate sessions. METHODS: We used a method for testing changes in pain sensitivity of human subjects (REDSTIM) where the stimulus temperature is modulated to clamp pain intensity near a desired set-point. Temperature serves as the response variable and is used to infer pain sensitivity. Several measures were analyzed for reliability including average temperature and area under the curve (AUC). Intraclass correlation coefficients were calculated for each measure at pain rating set-points of 20/100 and 35/100. RESULTS: Sixteen healthy individuals (mean age = 21.6 ± 3.9) participated in three experiments two days apart at both pain rating set-points. Most reliability coefficients were in the moderate to substantial range (r's = 0.79 to 0.94) except for the negative AUC (r = 0.52), but only at the 20/100 pain rating set-point. CONCLUSIONS: The present study supports the test-retest reliability of pain intensity clamping using the REDSTIM methodology while providing a novel tool to examine human pain modulatory mechanisms and overcoming common shortcomings of conventional quantitative sensory testing methods.
Modulation of the Cutaneous Silent Period in the Upper-Limb with Whole-Body Instability
(PLOS, 2016-03-16) Eckert, Nathanial R.; Poston, Brach; Riley, Zachary A.; Department of Kinesiology, School of Physical Education and Tourism Management
The silent period induced by cutaneous electrical stimulation of the digits has been shown to be task-dependent, at least in the grasping muscles of the hand. However, it is unknown if the cutaneous silent period is adaptable throughout muscles of the entire upper limb, in particular when the task requirements are substantially altered. The purpose of the present study was to examine the characteristics of the cutaneous silent period in several upper limb muscles when introducing increased whole-body instability. The cutaneous silent period was evoked in 10 healthy individuals with electrical stimulation of digit II of the right hand when the subjects were seated, standing, or standing on a wobble board while maintaining a background elbow extension contraction with the triceps brachii of ~5% of maximal voluntary contraction (MVC) strength. The first excitatory response (E1), first inhibitory response (CSP), and second excitatory response (E2) were quantified as the percent change from baseline and by their individual durations. The results showed that the level of CSP suppression was lessened (47.7 ± 7.7% to 33.8 ± 13.2% of baseline, p = 0.019) and the duration of the CSP inhibition decreased ( p = 0.021) in the triceps brachii when comparing the seated and wobble board tasks. For the wobble board task the amount of cutaneous afferent inhibition of EMG activity in the triceps brachii decreased; which is proposed to be due to differential weighting of cutaneous feedback relative to the corticospinal drive, most likely due to presynaptic inhibition, to meet the demands of the unstable task.
Purposeful Pedaling: Analyzing MS 150 Participant Behavior
(Emerald, 2015) Gregg, Elizabeth A.; Pierce, David A.; Sweeney, Kristi M.; Lee, Jason W.; Department of Kinesiology, School of Physical Education and Tourism Management
Purpose – The purpose of this paper is to explore factors affecting participant awareness, attraction, and attachment to the National Multiple Sclerosis Society’s (NMSS) MS 150 PGA Tour Cycle to the Shore charitable bike ride utilizing the Psychological Continuum Model (PCM) developed by Funk and James. In addition, the authors sought to outline variables sport organizations can use to predict donor behavior. Design/methodology/approach – Data for this project were derived from an electronic survey distributed to race participants and was analyzed in SPSS® software. Regression analysis was employed. Findings – The findings support previous research employing the PCM; wherein social situational variables have the greatest influence on the relational significance of hedonic and dispositional needs in attraction and attachment to sporting events. The work supports the inclusion of communities as an additional attachment outcome. Practical implications – In all, 92 percent of riders were informed about the event through word of mouth (WOM) marketing, highlighting the importance this promotional technique in the awareness stage of the PCM. NMSS would be well served by capitalizing on the power of WOM. Originality/value – The research provides insight into predictors of fundraising efficacy. In terms of fundraising effectiveness, participants with four or more years of participation were six times more likely than first-year riders to raise $1,000 or more.
Antioxidant vitamin C prevents decline in endothelial function during sitting
(International Scientific Information, 2015-04-07) Thosar, Saurabh S.; Bielko, Sylvanna L.; Wiggins, Chad S.; Klaunig, James E.; Mather, Kieren J.; Wallace, Janet P.; Department of Kinesiology, School of Physical Education and Tourism Management
BACKGROUND: This study was designed to test the hypothesis that antioxidant Vitamin C prevents the impairment of endothelial function during prolonged sitting. MATERIAL AND METHODS: Eleven men (24.2 ± 4.4 yrs) participated in 2 randomized 3-h sitting trials. In the sitting without vitamin C (SIT) and the sitting with vitamin C (VIT) trial, participants were seated for 3 h without moving their legs. Additionally, in the VIT trial, participants ingested 2 vitamin C tablets (1 g and 500 mg) at 30 min and 1 h 30 min, respectively. Superficial femoral artery (SFA) flow-mediated dilation (FMD) was measured hourly for 3 h. RESULTS: By a 1-way ANOVA, there was a significant decline in FMD during 3 h of SIT (p<0.001). Simultaneously, there was a significant decline in antegrade (p=0.04) and mean (0.037) shear rates. For the SIT and VIT trials by a 2-way (trial x time) repeated measures ANOVA, there was a significant interaction (p=0.001). Pairwise testing revealed significant between-SFA FMD in the SIT and VIT trial at each hour after baseline, showing that VIT prevented the decline in FMD 1 h (p=0.009), 2 h (p=0.016), and 3 h (p=0.004). There was no difference in the shear rates between SIT and VIT trials (p>0.05). CONCLUSIONS: Three hours of sitting resulted in impaired SFA FMD. Antioxidant Vitamin C prevented the decline in SFA FMD, suggesting that oxidative stress may contribute to the impairment in endothelial function during sitting.
Weight loss attitudes and social forces in urban poor Black and White women
(Ingenta Connect, 2015-01) Keith, NiCole R.; Hemmerlein, Kimberly A.; Clark, Daniel O.; Department of Kinesiology, School of Physical Education and Tourism Management
OBJECTIVE: To explore differences between Blacks and Whites in perceived influences on weight-related behaviors among obese urban poor women. METHODS: Participants (N = 27) received physician referrals to a weight loss program located in Federally Qualified Health Centers and either never attended or stopped attending. We conducted in-depth, in home interviews using a script informed by focus groups, pilot discussions, and the theory of planned behavior (TPB) to learn about participants' weight loss attitudes, social forces and perceived behavioral control. RESULTS: White women reported having more social support and social pressure for weight management activities. Black women reported eating for positive reasons whereas white women associated eating with negative emotions. CONCLUSION: Social networks and emotions may be critical factors in weight management and lifestyle program participation.
Novel method for assessing age-related differences in the temporal summation of pain
(Dove Medical Press, 2016) Naugle, Kelly M.; Cruz-Almeida, Yenisel; Fillingim, Roger B.; Staud, Roland; Riley, Joseph L.; Department of Kinesiology, School of Physical Education and Tourism Management
Temporal summation (TS) of pain protocols typically involve the delivery of brief repetitive noxious stimuli held at a constant intensity and measuring the consequent increase in the perceived intensity of pain sensations. To date, no studies have examined the effect of a TS protocol on the perceived spatial dimensions of the pain experience and its interaction with age. This study used a new TS protocol that examined changes in the perceived size of the painful area in 22 younger adults and 20 older adults. Four trials of ten brief heat pulses delivered at a constant intensity were administered on the volar forearm. Interpulse intervals (IPIs) were 2.5 seconds or 3.5 seconds. Subjects rated the peak pain intensity (trials 1 and 3) or the size of the painful area (trials 2 and 4) after each pulse on a 0-100 scale. The magnitude of summation was calculated for each trial. Three seconds and 6 seconds after delivering the last heat pulse, the subjects rated the intensity or the size of any remaining pain (aftersensations). The results indicated that older adults compared to younger adults exhibited significantly greater summation of size ratings for the 2.5-second and 3.5-second IPI trials and size of pain aftersensations at 3 seconds following the 2.5-second IPI TS trial. These results suggest that aging is associated with enhanced endogenous facilitation of the perceived size of pain. The potential clinical and mechanistic implications of enhanced TS of size of pain remain unknown and warrant further investigation.
PARCS: A Safety Net Community-Based Fitness Center for Low-Income Adults
(2016) Keith, NiCole; Mi, Deming; Alexander, Kisha; Kaiser, Stephanie; de Groot, Mary; Department of Kinesiology, School of Physical Education and Tourism Management
Background: Physical activity (PA) and fitness are critical to maintaining health and avoiding chronic disease. Limited access to fitness facilities in low-income urban areas has been identified as a contributor to low PA participation and poor fitness. Objectives: This research describes community-based fitness centers established for adults living in low-income, urban communities and characterizes a sample of its members. Methods: The community identified a need for physical fitness opportunities to improve residents’ health. Three community high schools were host sites. Resources were combined to renovate and staff facilities, acquire equipment, and refer patients to exercise. The study sample included 170 members older than age 18 who completed demographic, exercise self-efficacy, and quality of life surveys and a fitness evaluation. Neighborhood-level U.S. Census data were obtained for comparison. Results: The community-based fitness centers resulted from university, public school, and hospital partnerships offering safe, accessible, and affordable exercise opportunities. The study sample mean body mass index was 35 + 7.6 kg/m2 (class II obesity), mean age was 50 ± 12.5 years, 66% were Black, 72% were female, 66% completed some college or greater, and 71% had an annual household income of less than $25,000 and supported 2.2 dependents. Participants had moderate confidence for exercise participation and low fitness levels. When compared with census data, participants were representative of their communities. Conclusion: This observational study reveals a need for affordable fitness centers for low-income adults. We demonstrate a model where communities and organizations strategically leverage resources to address disparities in physical fitness and health.
