Impact of a Dynamic Orthosis on Manual Dexterity Among People With Parkinson’s Disease: A Randomized Trial
No full textImportance: A dynamic elastomeric fabric orthosis could be a novel nonpharmacological treatment of motor symptoms among people with Parkinson’s disease (PD).
Objective: To evaluate the efficacy of the orthosis in improving manual dexterity among people with PD.
Design: A randomized trial with 60 participants (control group, n = 20; experimental group, n = 40). Manual dexterity was assessed in on–off states of the disease, with and without the orthosis.
Setting: Burgos University Hospital (Burgos, Spain).
Participants: Consecutive nonprobabilistic sampling. Patients were included if they had been diagnosed with PD, had motor symptoms in at least one upper limb, and attended the hospital’s neurology department. Participants were ages 48 to 89 yr, with an average disease duration of 5.38 yr (SD = 4.23). Exclusion criteria were tremor due to another neurological disease or a Montreal Cognitive Assessment score ≤26.
Intervention: The experimental group used the orthosis on the most affected upper limb for 2 mo; the control group participants did not receive the orthosis.
Outcomes and Measures: Manual dexterity was measured with the Purdue Pegboard Test, Minnesota Manual Dexterity Test, and Square Test. Paired t tests for related samples and analysis of covariance tests were used.
Results: Some participants improved on some manual dexterity items while wearing the orthosis. However, it was not sustained when the orthosis was removed after 2 mo of use.
Conclusions and Relevance: The orthosis may improve certain aspects of manual dexterity and functionality among people with PD, but only while it is worn.
Plain-Language Summary: The common motor symptoms and declines in manual dexterity that people with Parkinson’s disease (PD) experience can significantly affect their ability to perform activities of daily living as well as their quality of life. Manual dexterity is a strong predictor of the level of functional independence for people with PD. This study evaluated the efficacy of an elastomeric fabric orthosis to improve manual dexterity for people with PD. The study found that while wearing the orthosis the motor symptoms of PD were reduced and manual dexterity and upper limb functionality improved. Wearing the orthosis has the potential to enhance functionality, foster greater autonomy, and substantially improve the quality of life of people with PD.This study was supported by grants for the financing of research projects in biomedicine, health management and social health care approved by the Regional Health Management of the Junta de Castilla y León (No. EXP.

Compressive Behaviour of Concrete Mixtures with Simultaneous Additions of Waste Wind-Turbine Blade and Coarse Recycled Concrete Aggregates
No full textComunicación presentada en: 4th fib International Conference on Concrete Sustainability 2024, durante los días 11-13 de septiembre en Guimaraes (Portugal)The development of more sustainable materials for the construction
sector begins with optimal use of natural resources and appropriately recycling
the residues produced at the end of the lifecycle of infrastructures. In the coming
years, many wind-farms will be dismantled, providing big amounts of waste windturbine blade (WWTB). This waste can be an opportunity to decarbonize the
construction industry, which causes huge green-house-gas emissions each year
endangering the environment.
Waste generated during the demolition of concrete elements has been used in
the past few years for structural concrete manufacturing in the form of Recycled
Concrete Aggregate (RCA). Feasibility of combination of RCA with WWTB has
yet to be study in concrete mixtures.
This study aims to analyze the simultaneous use of RCA and WWTB to
produce a greener concrete mixture as an effort to transform an industry hitherto
considered polluting into a more sustainable one. For this purpose, three concrete
mixtures were produced with different volume combinations of each waste: 0%
WWTB and 0% RCA; 5% WWTB and 50% RCA; and 10% WWTB and 100%
RCA. Compressive strength, modulus of elasticity and Poisson´s coefficient have
all been evaluated at 28 days. Results show that an adequate dosage of both types of
residues can result in a structural concrete mixture that preserves basic compressive
strength properties while at the same time providing an outlet for a large amount
of waste generated in both construction and wind energy sector.This research work was supported by the Spanish Ministry of Universities, MICINN, AEI, EU, ERDF and NextGenerationEU/PRTR [grant numbers PID2023-146642OB-I00; 719 10.13039/501100011033; TED2021-129715 B–I00]; the Junta de Castilla y León (Regional Government) and ERDF [grant number UIC-231; BU033P23
Full vector archaeomagnetic dating of an Early Iron Age archaeological settlement: El Castillar site (Navarra, northern Spain)
No full textDuring the course of the excavations of the Early Iron Age site of El Castillar (northern Spain), a well-preserved burnt level was discovered. The wide time interval provided by four 14C dates (ca. 800–––416 BCE) offered a good opportunity to perform a full-vector archaeomagnetic study to date the last heating and site abandonment. These studies analyze the remanent magnetization acquired by ferromagnetic minerals after a heating event. For this purpose, eight magnetically oriented hand blocks were collected, and we performed a suite of rock-magnetic experiments and X-ray diffraction analyses along with paleomagnetic and archaeointensity determinations with the Thellier-Coe and Tsunakawa-Shaw methods. Paleomagnetic analyses yielded a mean direction of Declination = 14.9˚ and Inclination = 58.6˚ (α95 = 4.1˚, k = 214, n = 7/8). Successful archaeointensity results were obtained with the Thellier-Coe method, which yielded a mean intensity value of 64.3 ± 1.8 µT (VADM = (10.8 ± 0.3)*1022 Am2). The main magnetic carrier is magnetite with Mg-cation substitutions. A full-vector archaeomagnetic dating, using the SCHA.DIF.4 k geomagnetic model and the Iberian Iron Age PSVC (at 95 % confidence), suggested different compatible age intervals. The youngest is the archaeologically most consistent one, which narrows the dating range to only a few decades according to the Iberian − Iron Age PSVC (685–––655 yr BCE). The relatively high intensity values obtained are compatible with the occurrence of the Levantine Iron Age Anomaly (LIAA) in Western Europe, although not at its highest values. The potential of archaeomagnetism over other dating techniques to accurately date Early Iron Age combustion events is demonstrated.This research has been supported by project PID2019105796GB-I00 of the Agencia Estatal de Investigaci´ on (Spain) and project BU037P23 of the Junta de Castilla y Le´ on (Spain) and the European Regional Development Fund.

Análisis de la construcción de la identidad profesional de un docente de educación física a través de su práctica educativa
No full textEste estudio analiza la construcción de la identidad profesional (IP) de un docente de Educación Física (EF) a partir de su práctica educativa. Se enfoca en el aprendizaje percibido y la gestión de miedos e inseguridades, tanto del docente como del alumnado. Desde un enfoque cualitativo y autoetnográfico, se examina cómo la experiencia, la interacción con los estudiantes y la reflexión pedagógica influyen en la evolución docente. Se observa que la aplicación de metodologías innovadoras y la autoevaluación favorecen la adaptación y mejora continua. Asimismo, se identifican inseguridades relacionadas con la gestión del aula, la percepción de competencia motriz y la comparación entre iguales. La superación de estos desafíos fomenta un aprendizaje más autónomo y participativo. La investigación concluye que la EF es un espacio transformador que, además del desarrollo motriz, impacta en la educación en valores, la socialización y el crecimiento personal del alumnado y del docente.This study analyzes the construction of the professional identity (PI) of a Physical Education (PE) teacher based on their educational practice. It focuses on perceived learning and the management of fears and insecurities, both from the teacher and the students. Using a qualitative and autoethnographic approach, the study examines how experience, student interactions, and pedagogical reflection influence teacher development. The application of innovative methodologies and self-assessment are observed to enhance adaptability and continuous improvement. Additionally, insecurities related to classroom management, motor competence perception, and peer comparison are identified. Overcoming these challenges fosters more autonomous and engaged learning. The research concludes that PE is a transformative space that, beyond motor skill development, plays a crucial role in values education, socialization, and personal growth for both students and teachers.Doctorado en Educació
Circadian rhythms in the university community: perception of health (dis) synchronisation
No full textThe aim of this research is to analyze circadian typologies in the community of the University of Burgos (Spain). In this study, 1,067 participants from three groups (students (ST), administrative and service staff (AS) and teaching and research staff (TR)) from all the educational centers completed the Morningness-Eveningness Questionnaire (MEQ) adapted to Spanish. The majority of the circadian typology in the three groups was intermediate, with a percentage higher than 60% in each of them. With this in mind, certain socio-demographic factors were also evaluated, such as age and gender. Younger participants tended to have an evening circadian typology. In terms of gender, both male and female participants who were not in the middle of the day were more representative of the morning typology. To complement the study, 9 participants were interviewed to explore the health effects of chronotype synchronisation/(de)synchronisation in the different university groups, with a stronger influence observed in students and teaching and research staff.This research is a result of the following projects: TED2021-131563B-I00 funded by MCIN/AEI/10.13039/501100011033 and by the ‘European Union NextGenerationEU/PRTR’; PID2022-139477OB-I00, funded by MCIN/AEI/10.13039/501100011033 and by ‘ERDF A way of making Europe’, by the ‘European Union’; INVESTUN/22/BU/001, Junta de Castilla y León, Consejería de Industria, Comercio y Empleo and BU042G24, from Consejería de Educación.
