Technology of Auto Teller Machine Interface: Accessibility for Bank Customer with Visual Impairments

Auto Teller Machine (ATM) is one of the banking facilities that attract customers with visually impaired to take advantage of banking services. However, there are still some obstacles faced to utilize technology related to ATM, this is because the technology owned by a number of ATMs is not in accordance with the conditions of customers with visual impairments. Therefore, this study aims to determine the ability of customers with visual impairments in operating ATM machines and determine the difficulties experienced when operating them. This research uses a quantitative descriptive research method by using the main research instrument in the form of a questionnaire and supporting data obtained through focus group discussions conducted with a number of respondents selected purposively. The results show that there are several difficulties faced by customers with visual impairments when using ATM facilities provided by banks. These difficulties include difficulty accessing ATM locations, queuing to use ATMs, inserting cards and taking cash out of ATM machines, taking proof of transaction slips, and difficulties when experiencing errors when using ATM machines that are not equipped with security personnel, so they have difficulty reporting the obstacles they face. While the most common difficulties experienced by customers with visually impairments when dealing with ATM machines are accessing information contained on the ATM screen, entering the pin number on the ATM machine that is not equipped with a button that can help customers with visually impaired, following the instructions for use listed on the ATM screen, as well as typing on the ATM screen type touch screen.

Cladding Profilometry Analysis of Experimental Breeder Reactor-II Metallic Fuel Pins with HT9, D9, and SS316 Cladding

BISON finite element method fuel performance simulations were conducted using an existing automated process that couples the Fuels Irradiation & Physics Database (FIPD) and the Integral Fast Reactor Materials Information System database by writing input files and comparing the BISON output to post-irradiation fuel pin profilometry measurements contained within the databases. The importance of this work is to demonstrate the ability to benchmark fuel performance metallic fuel models within BISON using Experimental Breeder Reactor-II fuel pin data for a number of similar pins, while building off previous modeling efforts. Changes to the generic BISON input file include implementing pin specific axial power and flux profiles, pin specific fluences, frictional contact, and irradiation-induced volumetric swelling models for cladding. A statistical analysis of irradiation-induced volumetric swelling models for HT9, D9, and SS316 was performed for experiments X421/X421A, X441/X441A, and X486. Between these three experiments, there were 174 post-irradiation examination (PIE) profilometries used for validating the swelling models presented using a standard error of the estimate (SEE) method. Implementation of the volumetric swelling models for D9 and SS316 claddings was found to have a significant impact on the BISON profilometry simulated, where HT9 clad pins had an insignificant change due to low fluence values. BISON profilometry simulated for HT9, D9, and SS316 fuel pins agreed with PIE profilometry measurements, with assembly SEE values being 4.4 × 10−3 for X421A, 2.0 × 10−3 for X441A, and 2.8 × 10−3 for X486. D9 clad pins in X421/X421A had the highest SEE values, which is due to the BISON simulated profilometry being shifted axially. While this work accomplished its purpose to demonstrate the modeling of multiple fuel pins from the databases to help validate models, the results suggest that the continued development of metallic fuel models is necessary for qualifying new metallic fuel systems to better capture some physical performance phenomena, such as the hot pressing of U-Pu-Zr and the fuel cladding chemical interaction.

Abbreviation noun phrases at the intersection of abbreviation and syntactic motivations

The paper focuses on acronym-based noun phrases, i.e. noun phrases consisting of an abbreviation and a non-abbreviated lexeme. The author works with the theory of lexical motivation which presumes the existence of several types of motivation, including abbreviation and syntactic motivation. While abbreviations are formed by means of abbreviation motivation, syntactic constructions such as noun phrases are formed by means of syntactic motivation. Both types of motivation are dominant in the forming of abbreviation noun phrases. The author distinguishes and explains the differences between tautological (PIN number), semi-tautological (SIM card) and explicative noun phrases (GPRS platforms) as well as abbreviation multi-word units (USB port). The paper points out manifold functionality of each type of abbreviation noun phrase/multiword unit and presents abbreviations as productive means of forming new constructions and lexemes. Their versatile character makes abbreviations universal forms for coining new expressions of terminological character and thus contributing to multiple terminological databases of languages.

Introducing Negative Pressure Wound Therapy for Lower Limb Defects: A Report of Three Cases of Open Fractures Fixed with Ilizarov External Fixator

The Ilizarov external fixator fixes the ring frame to the bone using steel wires and pins, then connects the plurality with rods. It enables stronger fixation and adjustment in various angles and directions than that by other modular external fixators. It is often used for damage control and reduction fixation of open fractures, but there are difficulties in handling necrotic skin and soft tissue over time. In particular, when the bone is exposed, it is recommended to cover it with a flap or skin graft as soon as possible. However, in cases of a wound surrounded by an Ilizarov external fixator, flap plasty would be challenging due to the large number of steel wires and pins inserted. Therefore, the wound needs to be carefully managed until it is closed.We report three cases of lower limb open fractures with tissue defect, in which negative pressure wound therapy was introduced simultaneously with fixation using the Ilizarov external fixator and proper wound management.

Reduced Pin-Count Test Strategy for 3D Stacked ICs Using Simultaneous Bi-Directional Signaling Based Time Division Multiplexing

3D Stacked Integrated Circuits (SICs) offer a promising way to cope with the technology scaling; however, the test access requirements are highly complicated due to increased transistor density and a limited number of test channels. Moreover, although the vertical interconnects in 3D SIC are capable of high-speed data transfer, the overall test speed is restricted by scan-chains that are not optimized for timing. Reduced Pin-Count Testing (RPCT) has been effectively used under these scenarios. In particular, Time Division Multiplexing (TDM) allows full utilization of interconnect bandwidth while providing low scan frequencies supported by the scan chains. However, these methods rely on Uni-Directional Signaling (UDS), in which a chip terminal (pin or a TSV) can either be used to transmit or receive data at a given time. This requires that at least two chip terminals are available at every die interface (Tester-Die or Die-Die) to form a single test channel. In this paper, we propose Simultaneous Bi-Directional Signaling (SBS), which allows a chip terminal to be used simultaneously to send and receive data, thus forming a test channel using one pin instead of two. We demonstrate how SBS can be used in conjunction with TDM to achieve reduced pin count testing while using only half the number of pins compared to conventional TDM based methods, consuming only 22.6% additional power. Alternatively, the advantage could be manifested as a test time reduction by utilizing all available test channels, allowing more parallelism and test time reduction down to half compared to UDS-based TDM. Experiments using 45nm technology suggest that the proposed method can operate at up to 1.2 GHz test clock for a stack of 3-dies, whereas for higher frequencies, a binary-weighted transmitter is proposed capable of up to 2.46 GHz test clock.

Code Based Proficient Transactions Based on QR Code with Biometric Authentication

Now a days the security dangers in the online ex-changes, ATM money withdrawals’ have expanded on a substan-tial scale. Individuals in the country zone are as yet ignorant of these dangers are as yet encountering many loses. Individuals unconscious of these dangers don't perceive that sharing their ATM PIN number, yet additionally sharing their credit/debit card number and CCV can likewise prompt the getting to of financial balance without their insight. In this way, in this proposed framework it is said that the credit/debit card number and CCV are being supplanted with dynamically produced QR codes. This QR code that is created can't be reproduced or hacked as effec-tively as the current framework. In the present framework OTP is sent to authenticate our transactions. This OTP is additionally added with Bio-metric confirmation like unique finger-print, iris information. This provides an additionally improved verification amid all the ATM exchanges. The execution on the above framework is basic as all the financial accounts are now linked with Aadhar card. And this can be implementing the QR code scanner alongside unique finger-print scanner and iris scanner in later stages. This never enables the unapproved clients to access or make any installments without the respective of the account holders. This expands the security level and furthermore enables the client to the exchange cash all the more securely. The pro-posed framework improves the security in the exchanges in our everyday life as no ATM withdrawal or Deposit should be possi-ble without the QR code and the Account holder themselves.

Design, manufacture and testing of a prototype obstacle-detection device at blind corners: an automated highway system technology

Abstract Traffic accidents on highways are attributed mostly to the "invisibility" of oncoming traffic and road signs. "Speeding" also causes drivers to reduce the effective radius of the vehicle path in the curve, thus trespassing into the lane of the oncoming traffic. The main aim of this paper was to develop a multisensory obstacle-detection device that is affordable, easy to implement and easy to maintain to reduce the risk of road accidents at blind corners. An ultrasonic sensor module with a maximum measuring angle of 15° was used to ensure that a significant portion of the lane was detected at the blind corner. The sensor covered a minimum effective area of 0.5 m2 of the road for obstacle detection. Yellow light was employed to signify caution while negotiating the blind corner. Two photoresistors (PRs) were used as sensors because of the limited number of pins on the microcontroller (Arduino Uno). However, the device developed for this project achieved obstacle detection at blind corners at relatively low cost and can be accessed by all road users. In real-world applications, the use of piezoelectric accelerometers (vibration sensors) instead of PR sensors would be more desirable in order to detect not only cars but also two-wheelers.

Supracondylar Humerus Fractures in Older Children: Success of Closed Reduction and Percutaneous Pinning.

The incidence of supracondylar humerus (SCH) fracture declines and fracture types change as children grow. Optimal treatment method is unclear in older children. The aim of the study was to determine if fracture type and configuration of distal humerus fractures changes as patients approach skeletal maturity, and to assess the success of closed reduction and percutaneous pin (CRPP) in extra-articular SCH fractures in this transitional age group. Inclusion criteria for this retrospective review were (1) distal humerus fractures with extension types 2 and 3, flexion type, T-type; (2) surgically managed, and (3) modified Sauvegrain score ≥1. Reviewed parameters included fracture type and configuration, grade of skeletal maturity, fixation technique, and loss of reduction. Primary analysis was to determine the distribution of fracture type and configuration with age or grade of skeletal maturity. Secondary analysis was used to determine the factors affecting treatment success of CRPP in extra-articular fractures. A total of 142 patients were included (58 males and 84 females). Fracture types revealed significant changes with increased age (P=0.031) and skeletal maturity grade (P<0.005). Skeletal maturity was a better predictor of changing fracture type than chronological age. T-type fractures were only seen in patients with modified Sauvegrain score ≥6 and flexion-type fractures were only seen in patients with modified Sauvegrain score ≤4. Loss of reduction rate after CRPP was 5%. The success of CRPP was not affected by age, sex, modified Sauvegrain score, fracture type, direction of displacement, coronal fracture pattern, number of pins or medial pin use. Fracture obliquity in the sagittal plane (P=0.05), suboptimal pin spread (P<0.01), and lack of bicolumnar fixation (P<0.01) were found as statistically significant factors associated with failed CRPP. The distribution of fracture type changed with increased age and skeletal maturity. CRPP of extra-articular fractures in older children is a reliable option regardless of the stage of skeletal maturity. Determinants of a good outcome include optimal pinning technique with adequate pin spread at the fracture site and bicolumnar fixation. Level IV-retrospective case series.

In order to achieve security and to overcome illegal activities, shortcoming of piracy in money transactions, we propose the idea of using fingerprints of customers and password instead of traditional use of PIN number. After authorized verification, the customer will be able to proceed for transaction else after four successive wrong attempts, the ATM card will be ejected automatically and a message will be sent to the registered mobile number. The proposed system is developed to provide better security to the ATMs. Keywords— ATM, Fingerprint, PIN, Biometric.

Effectiveness of Atm and Bank Security: Three Factor Authentications With Systemetic Review

Security is one of the key aspects in despite of time, location and domain. Providing a better security is an essential obligation to all sectors (state and private) and workers. Rendering better security is not only difficult but also fairly impossible due to growth of new technologies and constantly growing Information Technology domain. Rapid Improvement of banking sector provides many acceptable ways of managing the accounts, information and activities. This advancement has been a main driving force to the account activities with the help of Automatic Teller Machine (ATM). With the increase number of ATM usage among the public, hackers also use the technological growth to hack the data / information and apply the fraud actions. The said vulnerabilities have been increasing in a gradual manner and also ATM fraud has spread and become nightmare all around the world. This paper elaborates to mitigate the possible frauds can be happened at the ATM cubical with the hybrid multi-layered security concept. Here, previous studies were reviewed and compared in order to support to develop a system with the less loopholes. A three-layered architecture including PIN, OTP or finger print and pattern lock has been used in this system to mitigate the frauds. 400 students were selected to test the system and 384 students roughly 96% of students have successfully entered their pin number at the first attempt, in the second layer 95% of the students out of 384 students were succeeded and the third layer 99% of the students out of 363 students were success in drawing the patterns. The overall result of this evaluation process shows that, the suggested security tiers can be applicable since the accuracy in performance is better and accepted by the sample selected.

Multi-dimensional cubic symmetric block cipher algorithm for encrypting big data

The advanced technology in the internet and social media, communication companies, health care records and cloud computing applications made the data around us increase dramatically every minute and continuously. These renewals big data involve sensitive information such as password, PIN number, credential numbers, secret identifications and etc. which require maintaining with some high secret procedures. The present paper involves proposing a secret multi-dimensional symmetric cipher with six dimensions as a cubic algorithm. The proposed algorithm works with the substitution permutation network (SPN) structure and supports a high processing data rate in six directions. The introduced algorithm includes six symmetry rounds transformations for encryption the plaintext, where each dimension represents an independent algorithm for big data manipulation. The proposed cipher deals with parallel encryption structures of the 128-bit data block for each dimension in order to handle large volumes of data. The submitted cipher compensates for six algorithms working simultaneously each with 128-bit according to various irreducible polynomials of order eight. The round transformation includes four main encryption stages where each stage with a cubic form of six dimensions.

Effects of Processing Variables of Extrusion-Pultrusion Method on the Impregnation Quality of Thermoplastic Composite Filaments.

Carbon fibre-reinforced polypropylene composite filaments were fabricated via the extrusion–pultrusion method. One of the important factors influencing composites’ filament processability and structural properties is the impregnation quality, which can be represented by interfacial adhesion between the matrix and fibre. To improve the interfacial shear strength (IFSS) of the filament, four processing variables—melt temperature, pulling speed, number of pins in the impregnation die and fibre treatment—have been optimised using the Box–Behnken response surface methodology (RSM). Analysis of variance (ANOVA) was conducted to evaluate the linearity of the response surface models. Three levels were set for each independent variable. The melt temperature was varied at levels 190, 210 and 230 °C, while the pulling speed was set at three levels, namely, 40, 47 and 50 cm/min. The number of spreader pins was varied at 1, 2 and 3 pins, and there were three variations of the fibre treatment, namely, vinyltrimethoxysilane (VTMS), γ-aminopropyltriethoxy silane (APTS) and liquid nitrogen. Twenty-seven experimental runs were conducted, and a significant regression for the coefficient between the variables was obtained. The filament IFSS was measured by a customised pull-out test, and its surface morphology was characterised using a scanning electron microscope. ANOVA showed that fibre treatment significantly affected the IFSS due to their surface roughness, followed by pulling speed and melt temperature in quadratic order. Liquid nitrogen is recommended for carbon fibre treatment because of the high surface roughness, thereby providing a better matrix–fibre bonding effect. The results demonstrated that a melt temperature of 190 °C, pulling speed of 40 cm/min, three spreader pins and treatment of the fibre with liquid nitrogen afforded the optimum impregnation quality. It is important to keep a reasonable low processing temperature to obtain the geometrical stability of the product.

Adventures in study of the pressure losses in wire-wrapped rod bundle arrays

For the occasion of celebrating the 40th anniversary of the NURETH conference series, we present a brief overview of our work on the thermal-hydraulics of wire-wrapped rod bundles over these past four decades. In this context, this short technical note presents a personal perspective about this topic in a colloquial narrative. Particular focus is placed on a model for calculating hydraulic performance of rod bundles with wire spacers as used in sodium- and lead-cooled fast reactors. Since its first publication in 1986, this model has been often discussed by the international community at events like NURETH, sparking some suggestions for improvement. These issues have been addressed in a recent series of articles leading to an upgraded version published in 2018. This upgraded model yields a better overall prediction of all available experimental data and accurately represents some relevant geometrical aspects, such as the friction factor for two otherwise identical bundles but with different number of pins (bundle size effect). An outlook on the next steps for this effort is given, particularly from the point of view of using this model for licensing purposes.

Quelle est la configuration optimale pour la stabilité et la qualité de l’imagerie par résonance magnétique de la fixation externe temporaire des fractures du plateau tibial ?

IntroductionTemporary external fixation has been widely utilized in the stabilization of plateau fractures while waiting for an optimization of the soft tissue conditions before subsequent permanent internal fixation. Simultaneously, MRI is beneficial in the assessment of concomitant damage to ligaments and menisci so that these injuries could be promptly identified, and surgical planning executed at the time of definitive fixation of the bony injury. Increasing numbers of sidebars and pins have been previously suggested to increase frame rigidity but, at the same time, several studies have indicated the presence of MRI artifacts which may obscure key anatomical structures, even when MRI-compatible fixation devices are used. This study aims to identify, among six potential configurations, the construct that maximizes stability while most minimizing the number of MRI artifacts generated among different configurations commonly used. HypothesisThere is one or more configurations among the others that maximize stability while preserving a clinically acceptable level of MRI quality. Material and methodsSix constructs were recreated on cadaveric specimens and identified by the disposition of the bars: H, anterior, flash, hashtag, rhomboid, and diamond. Stage one evaluated the amount of artifact produced during MRI on instrumented cadaveric legs, as well as the signal-to-noise ratio (SNR) and the contrast-to-noise ratio (CNR) at five specific regions of interest. Stage two assessed the amount of compressional and torsional stiffness of the configurations on bone surrogate models. ResultsImage artifacts were not detected within the knee joint for all considered constructs. In terms of SNR The H, anterior, hashtag, and diamond configurations were not significantly different from their control (p>0.366) while the others were significantly different (p<0.03). The values of CNR found for the H and hashtag configurations were not significantly different from their controls (p>0.07) while the remaining configurations were significantly different (p<0.03). In compression, the H and diamond configurations had similar stiffness (p=0.468) of 35.78N/mm and 31.44N/mm, respectively, and were stiffer than the other configurations. In torsion, the constructs have shown different stiffness (p<0.001) with a minimum value of 0.66Nm/deg for the rhomboid configuration, which was significantly less stiff than the anterior configuration (1.20Nm/deg (p<0.001)). There was no difference between the diamond and H configurations (p=0.177) or between them and the hashtag configuration (p=0.215). DiscussionAn external fixator construct directly bridging the femur and tibia without interconnections is the most stable and produces MRI scans without image artifacts that would interfere with diagnostic quality.

Diminishing Returns and Deep Learning for Adaptive CPU Resource Allocation of Containers

Containers provide a lightweight runtime environment for microservices applications while enabling better server utilization. Automatic optimal allocation of CPU pins to the containers serving specific workloads can help to minimize the completion time of jobs. Most of the existing state-of-the-art focused on building new efficient scheduling algorithms for placing the containers on the infrastructure, and the resources to the containers are allocated manually and statically. An automatic method to identify and allocate optimal CPU resources to the containers can help to improve the efficiency of the scheduling algorithms. In this article, we introduce a new deep learning-based approach to allocate optimal CPU resources to the containers automatically. Our approach uses the law of diminishing marginal returns to determine the optimal number of CPU pins for containers to gain maximum performance while maximizing the number of concurrent jobs. The proposed method is evaluated using real workloads on a Docker-based containerized infrastructure. The results demonstrate the effectiveness of the proposed solution in reducing the completion time of the jobs by 23% to 74% compared to commonly used static CPU allocation methods.

The Islamic boarding school is a place for students to gain religious knowledge. The Santri period is the first time for most students to fully finance independently without parental supervision. Many students are unable to help financially so that they are increasingly irrational in buying their needs, the money charts in a short time after being sent money by their parents. One of the negative impacts of uncontrolled impact is the tendency of students to inform money when they know money. This research implements RFID as a payment instrument for students in the Islamic boarding school environment, through this payment system all santri financial data can manage the good expenses owned by these students. RFID is used for several processes or needs, namely checking balances, changing pins and processing payments. The results of RFID testing show a fast time in each process, namely the balance check process which takes an average of 1.55 seconds, the process of changing pin numbers on an average of 10.05 seconds, the payment process takes an average of 4.675 seconds.

Dependence of phantom current in a metal vapor laser on electrode geometry

It is observed that the discharge current in a copper vapor laser rises prior to the voltage breakdown. This current, which appears almost 50 ns before the discharge breakdown and is equivalent to almost 70% of the peak current at the time of breakdown, is termed the phantom current. It is reported that by reducing the residual electron density (phantom current) in a metal vapor laser (MVL), its performance can be significantly improved. Metallic pins are used in the electrode to facilitate discharge in the long discharge tube. Besides augmenting the discharge during the initial stage, it has a significant impact on the laser performance. In this paper, we find out the correlation between the phantom current and the electrode pin geometry and then present the optimum electrode geometry for improved laser performance. It was observed that the number of pins in the electrode affects the localized electric field in the nearby region and plays a dominant role in the quantum of the phantom current in the discharge tube of the laser. The MVL system was tested with electrodes that had a different number of pins (zero, eight and 36) and it was found that the phantom current is minimum when the electrode has zero pins and highest with an eight-pin electrode.

HPV Vaccine Searches on Pinterest: Before and After Pinterest's Actions to Moderate Content.

Objectives. To compare how human papillomavirus (HPV) vaccination was portrayed on Pinterest before and after the platform acted to moderate vaccine-related search results to understand (1) what the information environment looked like previously and (2) whether Pinterest's policy decisions improved this environment in terms of sources and content.Methods. In this quantitative content analysis, we compared 2 samples of 500 HPV vaccine-focused Pinterest posts ("pins") collected before and after Pinterest's actions to provide more reliable vaccine-related information. Pins were based on search results and were analyzed using the Health Belief Model.Results. The majority of preaction search results leaned toward vaccine skepticism, specifically focused on perceived vaccine barriers. Few pins were published by public health-related Pinterest accounts. Postaction search results showed a significant shift to HPV vaccination benefits, and the number of pins by government or medical accounts increased. However, the proportion of pins in search results containing HPV content of any type was significantly lower.Conclusions. Pinterest's efforts to moderate vaccination discussions were largely successful. However, the ban also appeared to limit HPV vaccination search results overall, which may contribute to confusion or an information vacuum.

Analysis of Pelvic Organ Prolapse-related Content on Pinterest.

Our study is a cross-sectional, qualitative study analyzing pelvic organ prolapse-related content on Pinterest, a social media platform that also functions as a visual search engine. Primary outcomes assessed include quality, understandability, and actionability of content. Secondary outcomes include levels of misinformation and commercial bias. Our study further characterizes sources of prolapse content and treatment modalities discussed. A Pinterest search was conducted using the term "pelvic organ prolapse," analyzing the first 100 relevant results. We examined the publisher of each pin and the writer of linked content. Using validated tools including the Patient Education Materials Assessment Tool and DISCERN criteria, we assessed understandability and actionability of content. We further compared content to professional guidelines for discussing and treating prolapse, evaluating for misinformation. We also evaluated for commercial bias and subjectively rated pin quality. Of pins evaluated, low understandability was found in 16, low actionability in 30, and low-to-moderate quality in 69. The most common publisher of pins was health and wellness groups, and the most common writer of content was physical therapists. Pelvic floor muscle training (PFMT) is the treatment modality discussed most frequently on Pinterest. Pinterest content discussing pelvic organ prolapse shows good levels of understandability for patients at all levels of health literacy. However, the number of pins showing poor actionability raises concern that content may not encourage readers to take direct steps toward prolapse assessment and management. In all, a majority of prolapse-related content on Pinterest was of low-to-moderate quality.

Functional implications of impaired bimanual force coordination in chronic stroke

BackgroundThe ability to coordinate forces with both hands is crucial for manipulating objects in bimanual tasks. The purpose of this study was to determine the influence of bimanual force coordination on collaborative hand use for dexterous tasks in chronic stroke survivors. MethodsFourteen stroke survivors (63.03 ± 15.33 years) and 14 healthy controls (68.85 ± 8.16) performed two bimanual tasks: 1) Pegboard assembly task, and 2) dynamic force tracking task using bilateral index fingers. The Pegboard assembly task required collaborative use of both hands to construct a structure with pins, collars, and washers. We quantified bimanual dexterity with Pegboard assembly score as the total number of pins, collars, and washers assembled in one minute. The force tracking task involved controlled force increment and decrement while tracking a trapezoid trajectory. The task goal was to match the target force with the total force, i.e., sum of forces produced by both hands as accurately as possible. We quantified bimanual force coordination by computing time-series cross-correlation coefficient, time-lag, amplitude of coherence in 0 – 0.5 Hz, and 0.5–1 Hz for force increment and decrement phases. ResultsIn the Pegboard assembly task, the stroke group assembled fewer items relative to the control group (p = 0.004). In the bimanual force tracking task, the stroke group showed reduced cross-correlation coefficient (p = 0.01), increased time-lag (p = 0.00), and reduced amplitude of coherence in 0–0.5 Hz (p = 0.03) and in 0.5–1 Hz (p = 0.00). Multiple regression analysis in the stroke group revealed that performance on Pegboard assembly task was explained by cross-correlation coefficient and coherence in 0.5–1 Hz during force increment (R2 = 0.52, p = 0.00). ConclusionsIndividuals with stroke show impaired bimanual dexterity and diminished bimanual force coordination. Importantly, stroke-related deterioration in bimanual force coordination was associated with poor performance on dexterous bimanual tasks that require collaboration between hands. Re-training bimanual force coordination in stroke survivors could facilitate a higher degree of participation in daily activities through improved bimanual dexterity.
