Цель - изучение качественных и количественных показателей папиллярных узоров дистальных фаланг пальцев рук у женщин пожилого возраста. Материал и методы. С помощью аппаратно-программного комплекса (АПК) «Малахит» определены типы кожного узора (дуга, радиальная петля, ульнарная петля и завиток), распространенность каждого типа на пальцах правой и левой руки, симметричность на гомологичных пальцах у 169 женщин пожилого возраста. Составлены формулы распределения для каждого типа узора на пальцах обеих рук. Статистический анализ результатов обследования проведен с использованием пакета прикладных программ SPSS 22.0. Результаты. Чаще регистрировались ульнарные петли, вторую группу по распространенности составили завитковые узоры, радиальные петли и дуги вошли в группу наиболее редких узоров. Выявлены статистически значимые билатеральные различия в распространенности завитковых и дуговых узоров на пальцах правой и левой кисти: наибольшее количество завитков зарегистрировано на пальцах правой кисти, дуговых узоров - на пальцах левой кисти. Чаще всего симметричные узоры регистрировали на V пальцах, значимо реже на II пальцах. Выводы. Изученные признаки папиллярных узоров являются маркерами, характеризующими особенности рельефа гребешковой кожи на дистальных фалангах пальцев рук у женщин пожилого возраста. Objective - to study the qualitative and quantitative indicators of papillary patterns of the elderly women distal phalanges. Material and methods. Papillary patterns were studied with the help of the «Malachite» software-hardware complex. Types of friction ridge patterns (arc, radial and ulnar loops, whorl) were determined; the prevalence of each type of pattern on all fingers of the right and left hands and the symmetry of friction ridge patterns on homologous fingers were studied in 169 elderly women. Formulas for each type of pattern on the fingers of both hands were developed. Statistical analysis of the study results was performed using the SPSS 22.0 software Results. The ulnar loops were recorded most frequently; the second most frequently found were whorls and radial loops, and radial loops and arcs were the rarest patterns. Statistically significant bilateral differences were found in the prevalence of whorls and arcs on fingers of left and right hands: the largest number of whorls was recorded on the fingers of the right hand, the largest number of arcs - on the fingers of the left hand. The symmetrical patterns were most frequently found on the fifth fingers, and significantly less frequent - on the second fingers. Conclusions. The studied features of skin patterns are markers that are characteristic for the ridged skin of the distal phalanges of elderly women.

A peculiarity of pension relations is that the right to a pension should actually arise before the appointment of a pension, that is, before the emergence of a pension legal relationship. Insurance pensions are fully covered by this provision. This indicates not only the connection between pension and labor relations, but also that qualitative and quantitative indicators of labor should be reflected in the employee's pension rights.

Because medical professionals lack the means to monitor exercises performed by patients in their home environment directly, there is a strong case for introducing technological solutions into this domain. They include methods that use wireless inertial sensors, which emit signals recorded and processed by special applications that work with mobile devices. This paper’s aim is (a) to evaluate whether such sensors are suitable for qualitative and quantitative motion analysis, and (b) to determine the repeatability of results over a few recordings. Knee joint activity was analysed using a system of inertial sensors connected through a Wi-Fi network to mobile devices. The tested individuals did eight different activities, all of which engaged the knee joint. Each excercise was repeated three times. Study results did not reveal any statistically significant differences between the three measurements for most of the studied parameters. Furthermore, in almost every case, there were no statistically significant differences between the results of the right and left lower limb (p > 0.05). This study shows that easy use and repeatability of results combined with the feature of quantitative and qualitative analysis make the examined method useful for functional evaluations of the knee joint.

Among a group of 12 persons selected for the ability to write with ease with either hand, none were found to write using a hooked hand posture with either the right or left hand. Tests of verbal and manipulospatial ability indicated a normal balance of these two types of abilities, usually associated with the left and right hemispheres. Findings are discussed in terms of implications for cerebral organization and hand position in writing.

It has previously been shown that, when stimuli positioned above or below a central fixation point (“up” and “down” stimuli) are assigned to left and right responses, the stimulus–response mapping up-left/down-right is more compatible than the mapping up-right/down-left for responses executed by the left hand in the left hemispace, but this relation is reversed for responses executed by the right hand in the right hemispace. In Experiment 1, each hand responded at locations in both hemispaces to dissociate the influence of hand identity from response location, and response location was found to be the determinant of relative compatibility. In Experiment 2 responses were made at the sagittal midline, and an inactive response switch was placed to the left or right to induce coding of the active switch as right or left, respectively. This manipulation of relative location had an effect similar to, although of lesser magnitude than, that produced by physically changing location of the response switch in Experiment 1. It is argued that these results are counter to predictions of a movement-preference account and consistent with the view that spatial coding underlies compatibility effects for orthogonally oriented stimulus and response sets.

ABSTRACT Objective:  To assess lateral differences between ossification events and stages of bone development in the hands and wrists utilizing Fishman's skeletal maturation indicators (SMIs). Materials and Methods:  The skeletal ages of 125 subjects, aged 8 to 20 years, were determined with left and right hand-wrist radiographs using Fishman's SMI assessment. Each subject was also given the Edinburgh Handedness Questionnaire to assess handedness. The skeletal ages of both hand-wrist radiographs were analyzed against each other, handedness, chronologic age, and gender. Results:  There were no significant differences overall in right and left SMI scores (P  =  .70); 79% of all patients showed no difference in right and left SMI scores, regardless of handedness, gender, or age. However, when patients were categorized based on clinical levels of SMI score for the right hand-wrist, there was a significant difference (P  =  .01) between the SMI 1-3 group and the SMI 11 group. Subjects in the SMI 1-3 group were more likely to show a left > right SMI score, while subjects in the SMI 11 group were likely to show a right > left SMI score. Conclusion:  Although no significant overall lateral differences in SMI scores were noted, it may be advisable to obtain a left hand-wrist radiograph and/or additional diagnostic information to estimate completion of growth in young surgical patients.

ABSTRACT:Background:Constructional impairment following left vs. right hemisphere damage has been extensively studied using drawing tasks. A confounding factor in these studies is that right-handed patients with left hemisphere damage (LHD) are often forced by weakness to use their non-dominant (left) hand or hemiparetic dominant hand. Qualitative differences in the drawing characteristics of left and right hand drawings by normal subjects have not previously been characterized. The present study was undertaken to determine the qualitative differences between left and right hand drawings of normal subjects.Methods:Thirty right-handed, elderly subjects without a history of neurological disease were asked to draw, from memory, seven objects using the right and left hand. Half of the subjects were randomly assigned to draw with the left hand first, and half the right hand first. Right and left hand drawings were compared using a standardized scoring system utilized in several previous studies of drawing in focal and diffuse neurological disease. Each drawing was scored on eighteen criteria. Right and left hand drawing scores were then compared using the t-test for paired samples or the Wilcoxon matched-pairs testResults:Drawings made using the left hand were found to be significantly simpler, more tremulous and of poorer overall quality than drawings made by the same subjects using the right hand.Conclusions:The deficits found in left versus right hand drawings of normals are similar to those found in patients with LHD, suggesting that much of the drawing impairment seen following LHD is due to an elementary motor disturbance related to use of the non-dominant hand.

AbstractWe used three dose levels (Sham, 2mA and 4mA) and two different electrode montages (unihemispheric or bihemispheric) to examine DOSE and MONTAGE effects on regional cerebral blood flow (rCBF) as a surrogate marker of neural activity, and on a finger sequence task, as a surrogate behavioral measure drawing on brain regions targeted by transcranial direct current stimulation (tDCS). We placed the anodal electrode over the right motor region (C4) while the cathodal or return electrode was placed either over a left supraorbital region (unihemispheric montage) or over the left motor region (C3 in the bihemispheric montage). Performance changes in the finger sequence task for both hands (left hand: p = 0.0026, and right hand: p = 0.0002) showed a linear tDCS dose response, but no effect of montage. rCBF in the the right hemispheric perirolandic area increased with dose under the anodal electrode (p = 0.027), while in the perirolandic ROI in the left hemisphere, rCBF showed a trend to increase with dose (p = 0.053), and significant effect of montage (p = 0.00004). The bihemispheric montage showed additional rCBF increases in frontomesial regions in the 4mA condition but not in the 2mA condition. Furthermore, we found correlations between rCBF changes in the right perirolandic region and improvements in the finger sequence task performance (FSP) for left and right hand. Our data support not only a strong direct tDCS dose effect for rCBF and FSP as surrogate measures of targeted brain regions, but also indirect effects on rCBF in functionally connected regions (e.g., frontomesial regions), particularly in the higher dose condition, and on FSP of the ipsilateral hand (to the anodal electrode). At higher dose and irrespective of polarity, a wider network of sensorimotor regions is positively affected by tDCS.Graphical AbstractHighlightstDCS-DOSE had linear effect on finger sequence performance for both handsrCBF changes in both perirolandic ROIs demonstrated tDCS-DOSE effects and left perirolandic ROI demonstrated tDCS-MONTAGE effects.Simulated current intensity in the left and right perirolandic ROI strongly correlated with the contralateral hand’s finger sequence performance.tDCS-Tolerability scores did not correlate with change in rCBF or finger sequence performance of the left hand.

The variability of fingerprints is widely used to identify a person in criminology, as adiagnostic-prognostic marker system in medicine and in the study of multi-vectoredethnogenetic processes in population surveys that cover different regions of the state.The purpose of the study is to outline the local structure of the male population ofUkraine by analyzing the indicators of digital dermatoglyphics for information on the vectorof evolution of the local population. Dermatoglyphic study was performed using H.Cummins and Ch. Midlo for 400 practically healthy men from different administrative-territorial regions of Ukraine. Statistical processing of the obtained results was carried outin the package STATISTICA 6.1 using nonparametric methods. High heterogeneity wasestablished on the basis of qualitative and quantitative indicators of signs of digitaldermatoglyphics among the following administrative-territorial groups: between theinhabitants of central and southern (22.22% of indicators), central and eastern (20.37% ofindicators) of central and western (15.74%), northern and southern (17.59% of indicators),northern and western (16.67% of indicators), northern and eastern (15.74% of indicators),western and eastern (12.04% of indicators) and southern and eastern (12.04% ofindicators) of the regions of Ukraine. Significant homogeneity was detected in terms ofqualitative and quantitative indicators of signs of digital dermatoglyphics inherent in men,residents of the northern and central regions of Ukraine (differences are recorded at 7(6.48%) indicators, as well as men living in the southern and western regions of thecountry (differences are recorded for 10-9.26% of indicators of only qualitativecharacteristics.) The obtained results allowed to distinguish two dermatological complexeson the territory of Ukraine: local north-central and local south-western. High taxonomicthe value for intra-population differentiation of the local level have: types of patternswith high intensity comb and the capacity of the pattern, especially the III and IV fingersof the right hand and I and II fingers of the left hand

Eye movements provide very critical information about the cognitive load and behaviors of human beings. Earlier studies report that under normal conditions, the left- and right-eye pupil sizes are equal. For this reason, most studies undertaking eye-movement analysis are conducted by only considering the pupil size of a single eye or taking the average size of both eye pupils. This study attempts to offer a better understanding concerning whether there are any differences between the left- and right-eye pupil sizes of the right-handed surgical residents while performing surgical tasks in a computer-based simulation environment under different conditions (left hand, right hand and both hands). According to the results, in many cases, the right-eye pupil sizes of the participants were larger than their left-eye pupil sizes while performing the tasks under right-hand and both-hands conditions. However, no significant difference was found in relation to the tasks performed under left-hand condition in all scenarios. These results are very critical to shed further light on the cognitive load of the surgical residents by analyzing their left-eye and right-eye pupil sizes. Further research is required to investigate the effect of the difficulty level of each scenario, its appropriateness with the skill level of the participants, and handedness on the differences between the left- and right-eye pupil sizes.

PURPOSE: The knowledge for the disease sarcopenia among the elderly population in Bulgaria is insufficient. Whole-body dual-energy X-ray (DXA) scans, anthropometric and clinical tests are used to diagnose it. Early screening of sarcopenia is an important strategy for the timely detection of this disease. The aim of the current study is to identify sarcopenia in the elderly through SARC-F questionnaire. METHODS: Data were obtained based on a questionnaire conducted by the student nurses in the Faculty of Public Health and Health Care of the University "Prof. Dr. Assen Zlatarov"-Burgas. A five-component SARC-F questionnaire was used to assess muscle strength. A sum equal to or greater than 4 is predictive of sarcopenia. 113 women aged ≥65 with a mean age of 74.6 ± 6.7 years were included in the study. RESULTS: 37% of the women had a total score corresponding to the risk of sarcopenia. The most common signs were a lack of muscle strength and an increased number of falls. The assessment of SARC-F might facilitate the physicians in the clinical practice to detect sarcopenia in the elderly population. CONCLUSIONS: SARC-F is a reliable method for the assessment of sarcopenia in elderly women.
