Compression and texture in socks enhance football kicking performance

The purpose of this study was to observe effects of wearing textured insoles and clinical compression socks on organisation of lower limb interceptive actions in developing athletes of different skill levels in association football. Six advanced learners and six completely novice football players (15.4 ± 0.9 years) performed 20 instep kicks with maximum velocity, in four randomly organised insoles and socks conditions, (a) Smooth Socks with Smooth Insoles (SSSI); (b) Smooth Socks with Textured Insoles (SSTI); (c) Compression Socks with Smooth Insoles (CSSI) and (d), Compression Socks with Textured Insoles (CSTI). Reflective markers were placed on key anatomical locations and the ball to facilitate three-dimensional (3D) movement recording and analysis. Data on 3D kinematic variables and initial ball velocity were analysed using one-way mixed model ANOVAs. Results revealed that wearing textured and compression materials enhanced performance in key variables, such as the maximum velocity of the instep kick and increased initial ball velocity, among advanced learners compared to the use of non-textured and compression materials. Adding texture to football boot insoles appeared to interact with compression materials to improve kicking performance, captured by these important measures. This improvement in kicking performance is likely to have occurred through enhanced somatosensory system feedback utilised for foot placement and movement organisation of the lower limbs. Data suggested that advanced learners were better at harnessing the augmented feedback information from compression and texture to regulate emerging movement patterns compared to novices.     

Representative design: Does the addition of a defender change the execution of a basketball shot?

ObjectiveThe aim of this study was to examine the influence of a defender on the performance of a motor skill from an invasion sport.DesignHighly skilled basketball players performed different variations of basketball shots using a randomised test schedule.MethodParticipants completed a total of 30 test trials comprising 6 trials of 5 different shot types in both defended and undefended conditions.ResultsThe presence of a defender led to significant changes in several behavioral measures including faster shot execution times, longer jump times, and an increase in the amount of time that the ball spent in the air as it travelled to the basket after being released from the shooter's hand. These behavioral changes were accompanied by an overall decline in shooting accuracy of over 20%. Defended shots also tended to elicit greater amounts of movement variability which, when interpreted in conjunction with the other findings, suggests that participants were attempting to adapt their movements to accommodate for the changing demands of the performance environment. Comparisons across different shot types revealed that the influence of the defender was generally context and task dependent.ConclusionsThe results have important implications for representative task design, and highlight how the manipulation of key information sources can have a marked effect upon behavioral responses.     

Measuring stress in clinical and nonclinical subjects using a German adaptation of the Perceived Stress Scale

Background/Objective: Stress is perceived differently across individuals, which might be particularly true for nonclinical and clinical subjects. For this reason, we tested a German adaption of the 10-item Perceived Stress Scale (PSS-10) for model fit and measurement invariance in a big nonclinical and clinical sample. Method: We (1) conducted multiple confirmatory factor analysis (CFA) in 1,248 nonclinical subjects and 575 outpatients, (2) measurement invariance with multigroup CFA, (3) assessed correlations with relevant constructs and (4) calculated internal consistencies for overall stress and the subscales Helplessness and Self-efficacy. Results: In both samples, CFA revealed a robust two-factorial structure with an excellent model fit. Group comparisons revealed strict measurement invariance. Correlations with associated measures support validity. Internal consistencies were good to very good. Conclusions: We show highly satisfactory psychometric properties of the German PSS-10 for nonclinical and clinical individuals. Measurement invariance analyses demonstrated that varying stress levels of people with a different mental health status are due to true interindividual differences.     

Moving from “I” to “We”: A Grounded Theory Analysis of Couple Therapy with Liver Patients and Their Partners

Prior research indicates that couples who cope with chronic illness from a relational “we” orientation experience more positive outcomes than couples that cope individually; however, little prior research identifies clinical processes that promote reciprocity or how societal gender processes are involved. This grounded theory analysis of 25 videotaped therapy sessions with six heterosexual couples coping with chronic liver disease (LD) used a feminist-informed relational lens to focus on the clinical processes involved in shifting from an individual to a relational orientation. Findings identified three contextual barriers to attaining a “we orientation”: (a) autonomy discourse, (b) illness-related power, and (c) gendered power. Analysis detailed therapist actions that decreased the impact of barriers to reciprocity and fostered relational coping. Clinical implications attend to complex intersections among gender, caregiving, and contextual barriers to reciprocity.     

Infidelity in the Time of COVID-19

Infidelity occurs in approximately 25% of marriages and is associated with various negative consequences for individuals (e.g., depression, anxiety, and post-traumatic stress), the couple relationship (e.g., financial loss, increased conflict, and aggression), and the couple's children (e.g., internalizing and externalizing behaviors). Infidelity is also one of the most frequently cited reasons for divorce. The increased stress brought on by the pandemic may be putting couples at an increased risk for experiencing infidelity, and data collected during the pandemic have shown that people across the United States are engaging in behaviors that are associated with a high likelihood of experiencing infidelity. The negative consequences of infidelity are also likely to be exacerbated for couples during the pandemic due to the intersection with the social, emotional, and financial consequences of COVID-19. Furthermore, couples are likely to experience disruptions and delays to the affair recovery process during the pandemic, which can negatively impact their ability to heal. Therefore, recommendations for navigating affair recovery during the pandemic, including adaptations for therapy, are also discussed.

The author shares musings and observations of key lessons learned from mentors and practice across over three decades.     

Polish Research Ethics Committees in the European Union System of Assessing Medical Experiments

The Polish equivalents of Research Ethics Committees are Bioethics Committees (BCs). A questionnaire study has been undertaken to determine their situation. The BC is usually comprised of 13 members. Nine of these are doctors and four are non-doctors. In 2006 BCs assessed an average of 27.3 ± 31.7 (range: 0–131) projects of clinical trials and 71.1 ± 139.8 (range: 0–638) projects of other types of medical research. During one BC meeting an average of 10.3 ± 14.7 (range: 0–71) projects of medical research were assessed (2006). The amendment of Polish laws according with Directive 2001/20/EC caused a percentage increase in BCs which assessed less than 20 projects per year (16% vs. 33% or 42% in 2003 vs. 2005 or 2006 respectively, p < 0,05). The results confirm the usefulness of the current practice of creating BCs by medical universities, medical institutes and regional chambers of physicians and dentists but rationalization of the workload for individual BCs is necessary.

The epistemically virtuous clinician

Today, modern Western medicine is facing a quality-of-care crisis that is undermining the patient–physician relationship. In this paper, a notion of the epistemically virtuous clinician is proposed in terms of both the reliabilist and responsibilist versions of virtue epistemology, in order to help address this crisis. To that end, a clinical case study from the literature is first reconstructed. The reliabilist intellectual virtues, including the perceptual and conceptual virtues, are then discussed and applied to the case study. Next, a similar method is employed to examine the responsibilist intellectual virtues, including curiosity, courage, honesty, and humility, and to apply them to the case study. To round out the discussion, the love of knowledge and both theoretical and practical wisdom are explored and applied to the case study. The paper concludes with a brief discussion of how the notion of an epistemically virtuous clinician addresses the quality-of-care crisis, in terms of the connection between ethical and intellectual virtues, and of the notion’s implications for medical education.

Clinical intuition versus statistics: different modes of tacit knowledge in clinical epidemiology and evidence-based medicine

Despite its phenomenal success since its inception in the early nineteen-nineties, the evidence-based medicine movement has not succeeded in shaking off an epistemological critique derived from the experiential or tacit dimensions of clinical reasoning about particular individuals. This critique claims that the evidence-based medicine model does not take account of tacit knowing as developed by the philosopher Michael Polanyi. However, the epistemology of evidence-based medicine is premised on the elimination of the tacit dimension from clinical judgment. This is demonstrated through analyzing the dichotomy between clinical and statistical intuition in evidence-based medicine’s epistemology of clinical reasoning. I argue that clinical epidemiology presents a more nuanced epistemological model for the application of statistical epidemiology to the clinical context. Polanyi’s theory of tacit knowing is compatible with the model of clinical reasoning associated with clinical epidemiology, but not evidence-based medicine.
