Published: November 2021

Penelitian ini memiliki tujuan untuk menganalisis orma sosiomatematik terhadap peserta didik yang berlangsung ketika pembelajaran daring matematika. Subjek dari penelitian ini adalah peserta didik SMKN 39 Jakarta. Metode penelitian ini menggunakan metode deskriptif kualitatif. Penelitian ini menggunakan penyebaran angket melalui Google Form dan Wawancara melalui Zoom Meeting. Berdasarkan hasil penelitian, terdapat 3 peserta didik yang berkreteria tinggi dalam norma sosiomatematik, terdapat 25 peserta didik yang berkreteria sedang atau standart, dan terdapat 2 peserta didik yang berkreteria rendah. Hasil penelitian menyimpulkan bahwa kualitas interaksi yang terbentuk dalam pembelajaran daring juga mengalami penurunan, dimana peserta didik hampir tidak melaksanakan diskusi secara daring dan presentasi. Namun dapat kita lihat bahwa peserta didik yang kreteria norma sosiomatematiknya tinggi lebih percaya diri untuk menarik kesimpulan. Maka norma sosiomatematik sangat berkenaan dengan hubungan antar individu, matematika dan masyarakat yang menekankan, bahwa pemahaman dan keyakinan peserta didik dapat ditimbulkan atai dimunculkan saat proses interaksi diskusi dalam pembelajaran, namun karena interaksi yang terjadi mengalami penurunan dalam esensi, maka pemahaman dan keyakinan peserta didik juga mengalami penurunan. Selain itu norma sosiomatematik yang dimiliki peserta didik sangat berpengaruh terhadap tingginya maupun rendahnya hasil pemahaman yang di peroleh pada saat pembelajaran matematika berlangsung.

تناول البحث الموسوم " التنمر الأخوي وخطورته - قصة يوسف أنموذجا-" . بيان أشد أنواع التنمر خطورةً ، ويمكن أن يُسمى العنف الصامت ؛ لأنه – غالباً- لا يُلقى له أهمية من قبل الوالدين مع ما يحويه من خطورة بالغة ، حيث يتعرض الأفراد إلى الأذى الجسدي الذي قد يصل إلى حالات الإصابة الشديدة أو الإعاقة أو القتل ، ولعل في قصة يوسف عليه السلام خير مثال على ذلك .

وتبرز أهمية البحث : ببيان أن التنمر الذي يمارسه بعض الأبناء تجاه إخوتهم، قد يكون أكثر خطورة من أي تعدٍ آخر، فالمتنمِّر يكون مطلعاً على جميع عيوب المتنمَّر عليه بحكم التقارب بينهما مما يجعله فريسة سهلة للتنمر.

ويهدف البحث الى بيان الخطورة العظمى للتنمر الأخوي، وأثر ذلك التعدي على التفكك الأسري التي هي نواة المجتمع.

وقد قُسِّم البحث الى مقدمة ومبحثين ، وخاتمة ، فالمقدمة احتوت على أهمية الموضوع وأهدافه.

وأما المبحث الأول: فقد تناول مفهوم التنمر، وموقف القرآن الكريم منه، وبيان خطورته ، وعلاجه.

وأما المبحث الثاني فقد تناول التنمر في قصة نبي الله يوسف عليه السلام ببيان الباعث على التنمر الأخوي ، وأنواعه في القصة ، وموقف المتنمَّر عليه.

Religious Syncretism
Authors: Bezklubaya Svetlana A.
Published: November 2021

The modern universal significance of the all-human creative experience updates the scientific interest in phenomena of culture which concentrate and disseminate the theories, ideas and beliefs that claim universal significance and cause epochal changes over vast territories. Religion, as a way of spiritual and practical mastery of the world by man, is that part of culture that constantly changes its forms, throws off some and clothes itself in others, fixing itself in cultural systems and actively influencing the processes of their self-organization and selfregulation. Therefore, the object of this study is religious syncretism as a way of transforming components of different order of being into a powerful culturecreative potential. The purpose of the work is to study religious syncretism as a complex multilevel process of mutual influence of various types of religions, sacred ideological images and cultural archetypes (ethical, aesthetic, artistic). The parameters of openness, and the mixing and blurring of boundaries make it possible to consider religious syncretism as a creative factor of culture, giving it the necessary integrity and actual meaning. Analysis of traditional forms of reflection and regulation of socio-cultural processes (myth, ritual, religion, art) reveals syncretism as a way of filling the sacred and religious with a powerful cultural-creative force. The author reveals the entropic essence of religious syncretism and its creative role in overcoming fragmentation, simplification and monism by culture (especially in the interpretation of the concepts of life and death, being and nothing, beautiful and ugly, space and time, virtue, soul, faith). The methodological basis of the research was formed by a transdisciplinary approach establishing a systemic life stance interaction of structurally functional and historical analysis with cultural and philosophical reflection. The theoretical conclusions contained in the work open up new opportunities for further study of the influence of religions on the creativity of cultural systems. The study of the culture-creative potential of religious syncretism clearly demonstrates the unity of the primary causes of being and thus allows one to practically reduce the degree of modern interfaith tension.
Media Trust and Persuasion
Authors: Kitamura Shuhei , Kuroda Toshifumi
Published: November 2021

This study examines the effect of media use on media trust and persuasion using a randomized field experiment in collaboration with a public broadcaster in a democratic setting. By randomly increasing the subjects’ capacity for viewing its TV programs, we found that this treatment increased support for government policies. The effect was driven by individuals trusting that broadcaster more than other broadcasters. Further, we found a divergence in trust levels, indicating the self-reinforcing nature of media trust and persuasion, which we call *endogenous persuasion*. To understand the mechanism underlying these findings, we developed a model and tested the prediction.

The possibility of significantly increasing the degree of regeneration in regenerative gas turbine plants without increasing the size of the recuperator.
Authors: Sevtsov Sergei V.
Published: November 2021

The proposed article considers the theoretical prerequisites and proposes a scheme for a regenerative gas turbine installation with an increase in the degree of regeneration at constant recuperator sizes in order to increase the efficiency of the installation. The new scheme excludes the supply of secondary (cooling the heat pipe and combustion products in the combustion chamber) air to the heat exchanger for heating. Reducing the air flow in the recuperator to the values of only the primary (for fuel oxidation) air flow with the recuperator area unchanged leads to an increase in the degree of regeneration and, accordingly, the efficiency of the plant.
A Toolkit for Analyzing Strategy Use in Phonemic Verbal Fluency Tasks preprint
Authors: Mackey Brandon , Sims Sara , Visscher Kristina , Vance David E.
Published: November 2021

The phonemic verbal fluency task is a common cognitive assessment of language and executive functioning which asks participants to list as many words as they can that begin with a given letter. Verbal fluency tasks are widely used to identify deficits in verbal fluency, which have been associated with disorders such as schizophrenia and dementia. Verbal fluency tasks are scored by the number of correct responses, however analysis of “clusters” of related words within a response list can give insights into the cognitive strategies used by participants. Unfortunately, manual word cluster analysis is time and labor intensive and inconsistent, since raters may cluster words differently depending on how they themselves have phonetically categorized the words. We present an automated pipeline for quantification of strategy use in the phonemic verbal fluency task, “LetterVF”. LetterVF is a python module (i.e., a script containing useful functions, which can be imported and used in other scripts) that uses a pronunciation dictionary to convert verbal fluency task data items into lists of phonemes, which can be analyzed to identify clusters of words that share similarities in any of several clustering categories. Additionally, LetterVF contains useful functions for identifying intrusions (words which do not follow the rules for the task), identifying perseverations (responses repeated within the same trial), counting the number of cluster switches in a list, and calculating the average size of clusters for a list. Analysis of data from 50 participants’ verbal fluency task responses indicated that analysis using LetterVF yields accuracy and consistency on par with manual analysis. Our hope is that this tool will allow researchers to get more out of their datasets, and explore new topics related to cognitive strategy use, such as how strategies change with age and differences in strategies between experimental groups.

The Importance of Maintaining the Momentum of Telemedicine after COVID-19
Authors: Siraj Aisha , Salehi Negar , Karim Saima
Published: November 2021

Telemedicine has been in existence for years with little traction for global mainstream medicine. COVID19 has exposed the importance of providing continued care for patients while minimizing the risk of exposure during pandemics. There has been robust growth in the use of telemedicine since the pandemic began rendering care possible while providing safety to patients and healthcare workers. Various digital applications are available to facilitate telehealth. Even in the absence of a pandemic, telemedicine allows the care of patients who may live in remote areas, or those who have issues with transportation or comorbidities prohibiting ambulation. This study is based on a questionnaire of providers who have been exposed to telemedicine during COVID19. A survey was shared in social media forums involving groups of physicians, and nurse practitioners who were willing to take the survey. Telemedicine is one of the best approaches to handling situations like pandemics or disease surges. In these circumstances, a virtual visit is beneficial for social distancing if a laptop, smartphone, or tablet is available, along with an internet or cellular coverage. Based on this survey conducted for healthcare workers from a variety of specialties, there was a considerable impetus for the continued benefit from telemedicine as an alternative to in-person visits for selected patients. Ongoing improvements in quality of applications/tools, education, and the cost are essential to maintain the benefits of telemedicine. There is also an ongoing necessity for vast improvements in healthcare policies and reimbursements.

Coronary artery embolism is an uncommon cause of acute myocardial infarction (AMI), while antiphospholipid syndrome (APS) is one of the rare reasons due to premature AMI. Coronary angiography can diagnose coronary artery embolism, and the positive serum of aPLs may infirm APS. We report a 32 years old man with ST-elevation AMI, without any high-risk factors of coronary artery disease. Coronary thrombosis was founded in the M1 sub-coronary of Left Anterior Descending (LAD), and the coronary artery was recanalized, the artery was not obstructive, Thrombolysis in Myocardial Infarction (TIMI) grade was III. He became shortness after exercise, the echocardiography showed his left ventricular was enlarged and LVEF was decreased. High titers of an anticardiolipin antibody (aCL) IgG of 46U (positive >20.0U), and it was positive at two dosages with an interval greater than 12 weeks. But there was no evidence of any other serum markers suggesting other associated pathologies such as SLE, so the primary APS was diagnosed. We gave him anticoagulation with warfarin and a single antiplatelet with Aspirin, the target INR was 2.5-3.0. Meanwhile, statins and hydroxychloroquine (HCQ) were all prescribed. After 6-months follow-up, his heart failure symptoms were disappeared, the LVDd and LVEF were all normal, the titer was decreased to nearly normal. In clinical background, young AMI without traditional high-risk factors of CAD, we should suspect APS. Therefore, we believed that HCQ may low thrombotic rate, down-trending aPLs titer, and prevent thrombotic recurrences in patients with primary antiphospholipid syndrome.

Published: November 2021

Mutations in the β-MYH7 gene are one of the major causes that lead to cardiomyopathies. However, to differentiate a causative nsSNP and its impact on protein structure remains a major challenge. In the present study, we detected a missense mutation Arg723His in the head motor domain of β-MYH7 in a HCM patient, and it was absent in 207 healthy individuals. The mutant (R723H) has been found to alter an evolutionarily conserved amino acid. In addition, the mutant (R723H) was predicted pathogenic by Polyphen-2 and SIFT bioinformatic tools. Further, the superimposed 3D structure of the mutant (p.His723 homology model) with native (p. Arg723) displayed the root means square deviation (RMSD) of ~3.38A0. We know that the non-covalent interactions such as hydrophobic, electrostatic, Van der Waals, and hydrogen bonds between amino acids are at the heart of stabilizing protein structures. Here, we demonstrated how the mutant (p.His723) has disrupted a critical non-covalent interactions network at the mutation site and may contribute to the disease phenotype. Hence, our findings in the future could pave the way for developing small molecular modulators or myosin-targeted therapies for heart failure.
Uncinate Fasciculus in Temporal Lobe Epilepsy
Authors: Ribbeck Lourdes Simbrón , Paredes Josefina Sandoval , Sánchez Karen Amador , Barajas Jesús Taboada
Published: November 2021

Background and purpose: Temporal lobe epilepsy is the most common focal intractable epilepsy. Uncinate fasciculus is a white fiber bundle that connects the orbitofrontal cortex with the anterior temporal lobe, and is implicated in most of the superior mental functions. There is evidence of uncinate fasciculus as a propagation pathway of seizures from temporal lobe. The aim of the study is to determine uncinate fasciculus alterations in patients with temporal lobe epilepsy, through fractional anisotropy. Methods: Thirty-three patients with temporal lobe epilepsy (10 right and 23 left) were studied. All of them were right-handed and had left hemisphere dominance for language. A 1.5 T MR imaging scanner was used to obtain diffusion tensor imaging (DTI). Fractional anisotropy of uncinate fasciculus was calculated through TBSS (Tract Based Spatial Statistics). Statistical analysis was done using IBM SPSS (v. 25). Results: Fractional anisotropy was higher in right uncinate fasciculus, regardless of epilepsy side. Right uncinate fasciculus, at the insula level, showed lower fractional anisotropy in patients with right temporal lobe epilepsy. Conclusions: Results support the evidence of uncinate fasciculus as a pathway of propagation in temporal lobe epilepsy, specially at insular level.

Interferencia cognitiva motora a través de la tarea dual, nivel de escolaridad en adultos mayores sanos: Una revisión narrativa
Authors: Aguirre Loaiza Héctor Haney , Roa Bedoya Jessica Alejandra , Vergara Suárez Angélica María
Published: November 2021

El ser humano está en constante interacción con el ambiente, y el cuerpo es fundamental para facilitar los procesos cognitivos. Esta tesis es fundamental en la teoría de la cognición corporizada (embodied cognition). El mundo moderno, en ocasiones, demanda esfuerzos motores y cognitivos de manera simultánea; por ejemplo, caminar y estimar una operación matemática. A este fenómeno se le conoce como interferencia cognitiva motora (ICM), el cual se evalúa a través de tareas duales. Con el propósito de identificar la tendencia de producción científica de la ICM y el rol del nivel de educación sobre el desempeño de las tareas duales en muestras de adultos mayores, se ha diseñado una revisión narrativa con una ventana de observación de diez años (2010-2019). Se encontraron 295 artículos, de los cuales se revisaron 242. Por criterios de inclusión, 187 fueron, y 55 cumplen con los criterios de elegibilidad. Las tareas duales más relevantes fueron Trail Walking Test (TMT), Walking while talking y Stroop Color-Word Test. Dentro de los estudios revisados no se logra identificar un efecto del nivel de educación. Se sugiere que se tengan en cuenta investigaciones donde se estudie el nivel de escolaridad y las tareas duales.
Prácticas de reconocimiento que emergen en los docentes de primaria y su repercusión en la inclusión educativa en población con discapacidad
Authors: López García Deicy Milena , López Rincón Ángela María , Castrillón Rivera Juan Esteban , Toro Zapata Jhon Wilmar
Published: November 2021

El presente trabajo da a conocer las dimensiones del reconocimiento (amor, derecho y solidaridad) de Axel Honneth, y pretende interpretar su repercusión en la inclusión educativa en docentes de primaria de la Institución Educativa Nuestra Señora de Guadalupe, del municipio de Dosquebradas, durante el año 2019. Como propósitos, se quiere comprender las prácticas de reconocimiento, describir las dinámicas de inclusión educativa e identificar actitudes y representaciones que emergen de los docentes en su accionar pedagógico. El enfoque de la investigación es de tipo mixto; el método es de carácter fenomenológico descriptivo, lo cual ayuda a entender cuáles son esas prácticas de reconocimiento que surgen a partir de las estrategias implementadas en el aula, por medio de las técnicas de encuesta, entrevista narrativa y autobiografía. Se ratifica la idea de que son insuficientes los conocimientos de los docentes para asumir una inclusión educativa adecuada y, por tanto, de que son escasas las prácticas de reconocimiento que emergen. Se concluye que las prácticas de reconocimiento de los docentes, que provienen de vivencias personales, vinculan en su accionar pedagógico a niños que requieren inclusión educativa; estas generan experiencias de aula donde los estudiantes se sienten amados, con derechos y vinculados en una sociedad que en ocasiones los menosprecia por su condición.

El capítulo plantea el proceso y el análisis de los resultados obtenidos en la investigación sobre las manifestaciones de las competencias ciudadanas y la convivencia en el aula, mediante la aplicación de una estrategia didáctica, dirigida a estudiantes de grado 4.° de básica primaria, en la Institución Educativa Sagrado Corazón de Jesús de Filandia, Quindío. La investigación es de tipo cualitativa con enfoque hermenéutico, a través de un estudio de caso, donde se observaron las competencias ciudadanas comunicativas, emocionales e integradoras que influyeron el pensar, actuar e interactuar en la convivencia. La unidad de trabajo la conformaron 29 estudiantes con edades entre los 9 y 10 años. Se utilizaron técnicas como observación, entrevistas, talleres y el diario de campo, entre otras. En la obtención de los resultados, se tomó como referencia a Enrique Chaux (2004), quien analiza las competencias ciudadanas y su contribución en el tipo de convivencia. Análisis que cobra sentido en las relaciones que se establecen en el aula; sin embargo, se requiere mejorar aspectos que orientan y dan sentido a las interacciones, tales como comunicación y emociones. En las competencias integradoras se evidencia necesidad de promover el interés en pensar, actuar e interactuar favoreciendo un clima nutritivo en el aula que fomente la democracia, participación, reconocimiento de derechos, obligaciones y el abordaje de conflictos de manera constructiva.

Background: Plant extracts may help to improve glycemic control in individuals with poor glycemic control. However, few studies have been investigated in the prediabetes cohort, which is a high-risk condition for T2DM. Thus, this study aimed to investigate the acute effect of grape seed, rooibos tea, and olive leaf extracts on postprandial blood glucose and insulin in participants with prediabetes. Methods: An acute, single-blind, placebo-controlled, non-randomized, crossover study (ACTRN12617000837325) where placebo and extracts of grape seed, rooibos tea and olive leaf standardized for total antioxidant capacity were given separately during an oral glucose tolerance test to participants (n=19, five men and fourteen women, aged 65.0 ± 1.6 years, Body Mass Index (BMI) 27.3 ± 1.1 kg/m2) with prediabetes (Glycated hemoglobin A1c (HbA1c) 42 ± 1 mmol/mol). The primary outcome incremental area under the curve of glucose (iAUCglucose) was examined with other glycemic measures.  Data was analyzed using linear mixed model for repeated measures. Secondary analysis was conducted by stratifying participants into either a healthier or less healthy subgroup based on the postprandial time to glucose and insulin peaks, with the less healthy subgroup experiencing delayed glucose and/or insulin peaks.Results: There were no overall significant changes to glucose and insulin measures between all plant extracts and placebo (p>0.05). Upon secondary analysis, all extracts affected glycemic responses in the less healthy subgroup. Compared to placebo, grape seed reduced plasma iAUCglucose(p=0.016, 21.9% reduction), 2 h postprandial glucose (2hPG) (p=0.034, 14.7% reduction) and metabolic clearance rate of glucose (MCRglucose) (p=0.016, 16.7% increase). It also improved insulin indices such as 2 h postprandial insulin (2hPI) (p=0.029, 22.4% reduction) and Stumvoll overall insulin sensitivity index (ISIoverall) (p=0.028, 15.0% increase). Rooibos tea extract significantly improved β-cell function as demonstrated by the increased oral disposition index (DI) (p=0.031, 32.4% increase) compared to placebo. Olive leaf extract significantly increased incremental area under the curve of insulin (iAUCinsulin) (p=0.040, 16.7% increase).      Conclusion: Grape seed, rooibos tea and olive leaf extracts demonstrated acute hypoglycemic benefits in adults with prediabetes and having less healthy metabolic profiles. A chronic study on the plant extracts is warranted to determine their longer-term impact on prediabetes.Trial Registration ID: ACTRN12617000837325Keywords: grape seed extract; rooibos tea extract; olive leaf extract; impaired glycemic control; hyperglycemia; hypoglycemic effects; insulin sensitivity; beta-cell function
Yes, no, maybe, I don’t know: Complexity and application of abstract argumentation with incomplete knowledge
Authors: Mailly Jean-Guy
Published: November 2021

Abstract argumentation, as originally defined by Dung, is a model that allows the description of certain information about arguments and relationships between them: in an abstract argumentation framework (AF), the agent knows for sure whether a given argument or attack exists. It means that the absence of an attack between two arguments can be interpreted as “we know that the first argument does not attack the second one”. But the question of uncertainty in abstract argumentation has received much attention in the last years. In this paper, we survey approaches that allow to express information like “There may (or may not) be an attack between these arguments”. We describe the main models that incorporate qualitative uncertainty (or ignorance) in abstract argumentation, as well as some applications of these models. We also highlight some open questions that deserve some attention in the future.
Is There Any Evidence of Monocytes Involvement in Alzheimer’s Disease? A Pilot Study on Human Postmortem Brain

Published: November 2021

Background:

The role of neuroinflammation has become more evident in the pathogenesis of neurodegenerative diseases. Increased expression of microglial markers is widely reported in Alzheimer’s disease (AD), but much less is known about the role of monocytes in AD pathogenesis. In AD animal models, bone marrow-derived monocytes appear to infiltrate the parenchyma and contribute to the phagocytosis of amyloid-β depositions, but this infiltration has not been established in systematic studies of the human brain postmortem.

Objective:

In addition to assessing the distribution of different subtypes of microglia by immunostaining for CD68, HLA-DR, CD163, and CD206, we focused on the involvement of C-chemokine receptor type2 (CCR2) positive monocytes during the AD course.

Methods:

We used formalin-fixed and paraffin-embedded tissue from four vulnerable brain regions (hippocampus, occipital lobe, brainstem, and cerebellum) from neuropathologically characterized AD cases at different Braak stages and age-matched controls.

Results:

Only singular migrated CCR2-positive cells were found in all brain regions and stages. The brainstem showed the highest number of positive cells overall, followed by the hippocampus. This mechanism of recruitment seems to work less efficiently in the human brain at an advanced age, and the ingress of monocytes obviously takes place in much reduced numbers or not at all.

Conclusion:

In contrast to studies on animal models, we observed only a quite low level of myeloid monocytes associated with AD pathology. Furthermore, we provide evidence associating early microglial reactions carried out in particular by pro-inflammatory cells with early effects on tangle- and plaque-positive vulnerable brain regions.

Erobots and the deterritorialization of eroticism
Authors: Schussler Aura-Elena
Published: November 2021

As a result of its accelerated evolution in the early 21st Century, technology has already extended far beyond mere instrumental status. In the not too distant future we can expect technology to move towards a new dimension in terms of fusing with human nature; most notably in the field of intimacy towards what are known as erobots (i.e., sexbots, augmented erotic characters, erotic chatbots, erotic avatars, etc.). Given that these erobots have every chance to become part of a future eroticism, this places erobots beyond the onto-metaphysical grounding of the Western tradition regarding objects. This is an aspect that attracts the dissolution of the anthropocentric legacy of Western metaphysics, within the parameters of OOO, by showing that, in this paradigm, so-called human uniqueness is suffering an ontological twist. To show this I am investigating, the scenario that involves the relationship between a sexbot and a human, alongside of that between two sexbots, within the limits of OOO. Consequently, I am addressing the issue of how a sexbot relates to both a human agent and to another sexbot. I am also analyzing the perspective in which a future presence of erobots in the intimate life of the individual will twist the traditional image of eroticism in Western culture. This perspective is opening a deconstructing process with regard to human exceptionalism – analyzed within the limits of the ‘deterritorialization’ of eroticism – from the traditional structures of Western metaphysical heritage. Such deterritorialization emphasizes the paradigm shift in which eroticism is leaving the familiar terrain of the metaphysics of presence and the fixed structures of societies’ ‘strata’. Thus, following the philosophical thinking of Gilles Deleuze and Félix Guattari, the ‘reterritorialization’ of eroticism – in the fluid, transversal and rhizomatic network of technology – is an ongoing, ever-changing process, taking place in the immanent sphere of techno-eroticism’s ‘plane of consistency’.
Post-Illumination Pupil Response as a Biomarker for Cognition in α-Synucleinopathies

Published: November 2021

Neurodegenerative processes in the brain are reflected by structural retinal changes. As a possible biomarker of cognitive state in prodromal α-synucleinopathies, we compared melanopsin-mediated post-illumination pupil response (PIPR) with cognition (CERAD-plus) in 69 patients with isolated REM-sleep behavior disorder. PIPR was significantly correlated with cognitive domains, especially executive functioning (r = 0.417, p < 0.001), which was more pronounced in patients with lower dopamine-transporter density, suggesting advanced neurodegenerative state (n = 26; r = 0.575, p = 0.002). Patients with mild neurocognitive disorder (n = 10) had significantly reduced PIPR (smaller melanopsin-mediated response) compared to those without (p = 0.001). Thus, PIPR may be a functional—possibly monitoring—marker for impaired cognitive state in (prodromal) α-synucleinopathies.
Application of nonlinear analysis for the assessment of gait in patients with Parkinson’s disease
Authors: Lukšys Donatas , Griškevičius Julius
Published: November 2021

BACKGROUND: Gait can be affected by diseases such as Parkinson’s disease (PD), which lead to alterations like shuffle gait or loss of balance. PD diagnosis is based on subjective measures to generate a score using the Unified Parkinson’s Disease Rating Scale (UPDRS). To improve clinical assessment accuracy, gait analysis can utilise linear and nonlinear methods. A nonlinear method called the Lyapunov exponent (LE) is being used to identify chaos in dynamic systems. This article presents an application of LE for diagnosing PD. OBJECTIVE: The objectives were to use the largest Lyapunov exponents (LaLyEx), sample entropy (SampEn) and root mean square (RMS) to assess the gait of subjects diagnosed with PD; to verify the applicability of these parameters to distinguish between people with PD and healthy controls (CO); and to differentiate subjects within the PD group according to the UPDRS assessment. METHODS: The subjects were divided into the CO group (n= 12) and the PD group (n= 14). The PD group was also divided according to the UPDRS score: UPDRS 0 (n= 7) and UPDRS 1 (n= 7). Kinematic data of lower limbs were measured using inertial measurement units (IMU) and nonlinear parameters (LaLyEx, SampEn and RMS) were calculated. RESULTS: There were significant differences between the CO and PD groups for RMS, SampEn and the LaLyEx. After dividing the PD group according to the UPDRS score, there were significant differences in LaLyEx and RMS. CONCLUSIONS: The selected parameters can be used to distinguish people with PD from CO subjects, and separate people with PD according to the UPDRS score.
