- Evaluation of the psychometric properties of the Stanford Health Assessment Questionnaire Disability Index (HAQ-DI) in people with Parkinson’s disease(Società Editrice Universo (SEU)) Galeoto, G; Simeon, R; Berardi, A; Panuccio, F; González-Bernal, J; Seco Calvo, Jesús Ángel; Fisioterapia[EN] The Stanford Health Assessment Questionnaire Disability Index (HAQ-DI) is a widely used patient-reported outcome for measuring functional disability during Activities of daily living (ADL) performance; Parkinson’s Disease (PD) leads to alterations in body function, limited performance in ADLs and increased dependency, resulting in reduced quality of life. The aim of the present study was to analyzed the psychometric properties of HAQ-DI in a population with PD. People with diagnosis of PD were recruited for this study. The psychometric properties analyzed were internal consistency and construct validity using the Parkinson’s Disease Questionnaire (PDQ-39) as gold standard. This study was conducted on 34 patients diagnosed with PD from February to October 2023. The internal consistency of the HAQ-DI was alpha=0.93. The study revealed significant correlations between the dimensions of the PDQ-39 and the subcategories of the HAQ-DI (0.030.91). Significant correlations also emerged between the demographic and clinical characteristics of participants and the subcategories of HAQ-DI. The HAQ -DI is a reliable and valid tool to assess ADLs in people with PD. This is the first study analyzing psychometric properties of this well-known assessment tool in a population with neurological disease, representing an important step to compare outcomes and ADLs independence in different populations.
- Exploring Sex Activity Impact on Biological Biomarkers and Athletic Parameters in Sexually and Physically Active Healthy Adults: A Systematic Review of Clinical Trials(MDPI) Fernández-Lázaro, Diego; Seco Calvo, Jesús Ángel; Izquierdo, José María; Mielgo-Ayuso, Juan; Roche, Enrique; Santamaría, Gema; Fisioterapia[EN] Background: A sexually active lifestyle is generally associated with positive effects on physical condition and health. However, engaging in sexual activity prior to a sports competition could affect athletic performance. This systematic review examines the cur- rent literature on the impact of pre-exercise sexual activity on sports performance, with particular attention paid to its effects on physiological, hormonal, cognitive, and percep- tual markers. Method: Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we systematically reviewed original studies published within the last 25 years. Eligible studies were randomized or non-randomized controlled design and indexed on PubMed, Scopus, Dialnet, and Cochrane. Additional sources were consulted including a network diagram with Connected Papers®. Two methodological quality scales, McMaster University Occupational Therapy Evidence-Based Practice Research Group and Physiotherapy Evidence Database (PEDro), were used. The study was registered in PROSPERO (#CRD42023426555). Results: A total of 244 records were identified through the search process, of which 7 studies met the inclusion criteria. The studies involved 117 (115 men) physically and sexually active subjects including 29 elite top athletes. When comparing the sexual activity condition/group (SexG) to abstinence (AbsG), significant (p < 0.05) decreases were observed in average speed and maximum strength. In contrast, non-significant trends towards improvement (p > 0.05) were observed in exercise capacity, reaction time, and muscular endurance. No significant changes (p > 0.05) were found in physiological and hormonal biomarkers and fatigue perception. However, per- ceived exertion was significantly higher (p < 0.05) in SexG compared to AbsG. Conclusions: Current evidence does not conclusively support the influence of pre-exercise sexual activity on sports performance, or physiological and hormonal biomarkers. However, it could contribute to increased perception of exercise intensity.
- MAC and ROTMAC in structures with closely spaced modes(Universidad de León, Servicio de Publicaciones) Aenlle, Manuel; García Fernández, Natalia; Fernández, Pelayo; Otros[EN] In models with closely spaced or repeated modes, small perturbations in mass or stiffness can cause significant rotations of the mode shapes within their local subspace. The rotation angle is dependent on both the closeness of the modes and the magnitude and location of the perturbation. Consequently, low MAC (modal assurance criteria) values may be obtained in the case of closely spaced modes, even in the case of low mass and stiffness discrepancies. The concept of ROTMAC and the relative angle between the mode shapes provides information of the shear and serves as an indicator of mass discrepancies between models. In this paper, simulations of two spring-mass systems are performed modifying the closeness of the modes, in order to study its effects in the MAC and the ROTMAC.
- Association Between Workplace Sedentary Behavior, Age, and Waist-to-Height Ratio in Spanish Male Workers: An Observational Study in a Large Occupational Cohort(MDPI) de Arriba Santos, Alejandro; Santamaría, Gema; Cobreros Mielgo, Raúl; Cacharro, Luis M.; López-Llorente, Álvaro; Jiménez-Callejo, Elena; Seco Calvo, Jesús Ángel; Fernández-Lázaro, Diego; Fisioterapia[EN] Prolonged sitting (PS) in the workplace has been linked to a higher risk of developing non-communicable chronic diseases. Simultaneously, an elevated waist-to-height ratio (WHtR) is considered a reliable measure of increased risk for the same condition. The main objective of this research was to examine the relationship between workplace PS and increased WHtR among male workers from the Spanish region of Castilla y León. The secondary objective was to assess how age affects elevated WHtR in workers. This retro- spective observational study was carried out in accordance with the STROBE guidelines. The sample included 85,670 male workers, categorized by job type (with or without PS) and age (<40 years or ≥40 years). Chi-square test (X2 ), Pearson correlation coefficients, and odd ratios (OR) were used to analyze associations. Among workers with PS, X2 = 0.73 (p = 0.391) and 1.11 (p = 0.292) were reported, and among those without PS, X 2 = 0.86 (p = 0.354) and 1.24 (p = 0.265), for the years 2022 and 2023, respectively. Therefore, there was no significant association between workers with or without PS and an elevated WHtR, both in those younger than and older than 40 years of age. Advanced age (≥40 years) showed a significant association with increased WHtR (p < 0.01; OR = 2.6). However, no statistical association was observed between PS and elevated WHtR (p > 0.05; OR = 1.15). These findings suggest that age plays a more prominent role than occupational PS time in WHtR among male workers. Future studies should consider other factors, including physical activity and dietary habits, that could affect WHtR
- Lightweigth impactor prototype for a drop tower testing machine, made on carbon fiber composite and additive manufacturing(Universidad de León, Servicio de Publicaciones) López Medina, Pablo; Castillo López, Germán; Beltrán Ramos, José Bernardo; García Sánchez, Felipe; Otros[EN] One of the most commonly used techniques to characterise the impact behaviour of viscoelastic materials is the drop weight impact test. The University of Málaga has an Instron CEAST 9350 for testing at speeds of up to 24 m/s. Currently, the lowest available mass is 2,4 kg, which is excessive for low-stiffness materials. The aim of this study is to design, calculate, and manufacture a lighter impactor, made from carbon-epoxy laminates and continuous carbon fibre additive manufacturing. Geometric constraints have been imposed to ensure its integration into the Instron CEAST 9350, as well as a maximum impact force of 22,5 kN. The proposed solution has been validated through explicit dynamic analysis using LSDYNA. As a result, a mass reduction of approximately 50% has been achieved. The developed structural concept will enable further mass reduction in the future for lower impact forces, depending on the material to be tested.
