AbstractThis study explored the effects of training computer mouse use in the nondominant hand on clicking performance of the dominant and nondominant hands. Computer mouse use is a daily operation in the workplace and requires minute hand and wrist movements developed and refined through practice and training for many years. Our study had eleven right-handed computer mouse users train their nondominant hand for 15 min a day, five days per week, for six weeks. This study found improved performance with the computer mouse in the dominant hand following nondominant hand training because of the bilateral transfer effect of training. Additionally, our study showed that the nondominant hand is capable of learning the complex movements that our dominant hand has trained for many years. Last, our research showed that nondominant hand performance decreases when the skill is not trained for over a year, but the performance is significantly higher than that prior to the original training and can be rapidly relearned. Overall, training the nondominant hand on the computer mouse will allow for improved performance in industry while allowing safer, sustainable, and more achievable work in a multitude of economies.

The focus of this research was to investigate how maximum torque and muscle forces were affected by pronation and supination, i.e., inward and outward rotation of the forearm in a series of screwdriver tests with 6 varied handles. Consecutively, maximum torque for pronation and supination was determined, submaximum isometric levels of torque were demanded, and, finally, an equal dynamic screwing work for all subjects was simulated. Physiological cost of performance was simultaneously measured by registrations of electromyographic activities (EA) from 4 muscles, which were expected to be involved intensively in screwing tasks. Significant and essential differences between maximum torque values produced by pronation and supination of the right and the left arm of the mainly right-handed subjects were found. For clockwise work, as it is necessary e.g., for driving in screws, inward rotations (pronations) of the nondominant hand are at least as strong as outward rotations of the dominant hand. Differences of about 8% favour of pronations were found. Yet, for counter clockwise work involved e.g., in removing a tightened screw, inward rotations of the dominant hand yielded a much more stronger torque strength than outward rotations of the nondominant hand. Differences of more than 50% right-handed subjects were measured. Also, EA values of the 4 muscles monitored on the right arm differed significantly. Systematically operational and physiological differences due to the varied screwdriver grips, as results of investigations which were not the main objective of the study, corresponded well with the findings of prior studies.

Background: Impairment of the dominant hand should lead to greater disability than impairment of the nondominant hand, but few studies have tested this directly, especially in the domain of upper-extremity peripheral nerve disorder. The aim of this study was to identify the association between hand dominance and standardized measures of disability and health status after upper-extremity peripheral nerve disorder. Methods: An existing database was reanalyzed to identify the relationship between affected-side (dominant vs nondominant) on individuals with unilateral upper-extremity peripheral nerve disorder (N = 400). Primary measure of disability was the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. Results: We found no differences in standardized measures of disability or health status between patients with affected dominant hand and patients with an affected nondominant hand. However, a post hoc exploratory analysis revealed that patients with an affected dominant hand reported substantially reduced ability to perform 2 activities in the DASH questionnaire: “write” and “turn a key.” Conclusions: Following unilateral upper-extremity peripheral nerve disorder, impairment of the dominant hand (compared with impairment of the nondominant hand) is associated with reduced ability to perform specific activities, but this reduced ability is not reflected in standardized measures of disability and health status. To adequately identify disability following unilateral impairment of the dominant hand with the DASH, individual items must be used instead of the total score. New or alternative measures are also recommended.

Objective. The purpose was to determine if upper extremity impairment and function in individuals with chronic stroke is dependent upon whether the dominant or non-dominant hand is affected. Methods. Ninety-three community-dwelling individuals with stroke. The Modified Ashworth Scale (tone), handheld dynamometry (isometric strength), monofilaments (sensation), Brief Pain Inventory (pain), Chedoke Arm and Hand Activity Inventory Motor Activity Log (paretic arm use), and Reintegration to Normal Living Index (participation) were used to form impairment and function models. Results. Multivariate analysis models (Dominance × Severity) were created for impairment and function variables. There was a significant interaction and main effect of Dominance for the impairment model ( P = 0.01) but not the function model ( P = 0.75). The dependent variables of tone, grip strength, and pain were all significantly affected by Dominance, indicating less impairment if the dominant hand was affected. All dependent variables except pain were affected by Severity. Conclusion. This study looked at the effect of the dominant hand being affected versus the nondominant in individuals with chronic stroke. Individuals with the dominant hand affected demonstrated less impairment than those with the nondominant hand affected. However, there was no effect of dominance on paretic arm use or performance in activities of daily living. Prospective studies to further explore the issue of hand dominance and poststroke function are suggested.

Crime Classification

In this paper, a detailed study on crime classification and prediction using deep learning architectures is presented. We examine the effectiveness of deep learning algorithms in this domain and provide recommendations for designing and training deep learning systems for predicting crime areas, using open data from police reports. Having time-series of crime types per location as training data, a comparative study of 10 state-of-the-art methods against 3 different deep learning configurations is conducted. In our experiments with 5 publicly available datasets, we demonstrate that the deep learning-based methods consistently outperform the existing best-performing methods. Moreover, we evaluate the effectiveness of different parameters in the deep learning architectures and give insights for configuring them to achieve improved performance in crime classification and finally crime prediction.

Aims: The first aim of the study was to examine the attentional performance of children (8–13 years of age) who practiced two different sport disciplines: Open skill sport – racket and closed skill sport – running and also to investigate the acute effects of these two specific training sessions on children’s immediate and delayed attentional performance. The second aim of the present study was to verify gender differences in attentional performance. Eighteen children+ (8 girls and 10 boys; age = 10.6 ± 1.5 yrs; height = 144.3 ± 12.2 cm; weight = 44.2 ± 12.5 kg; BMI = 20.8 ± 2.7 kg/m2) engaged in a racket sports and eighteen children (9 girls and 9 boys; age = 9.9 ± 1.2 yrs; height = 142.4 ± 9.5 cm; weight = 40.0 ± 8.6 kg; BMI = 19.6 ± 2.4 kg/m2) engaged in running were enrolled. Methods: Children’s training and experience with these activities averaged 2.3 (± 1.0) years. Children’s attentional capacity was measured before, immediately after and 50 minutes after each specific training session by the d2 test of attention. This paper -and -pencil letter cancellation test evaluated concentration and sustained attention under stress induced by a fixed executing time. A 2 (Sport: open vs closed skill) x 2 (Gender: boys vs girls) x 3 (Time: pre vs 0’ post vs 50’ post) repeated measures ANOVA for time was used to compare the effect of an open skill session and a closed skill session on the individual attentional variables. Results: Children of open skill sport showed higher attentional scores (higher processing speed - TN, higher concentration performance - CP and lower percentage of errors - E%; p < 0.01), improved CP from pre to 0’ post intervention (p = 0.01) and maintained this improved performance at 50’ post intervention (50’ post vs pre; p < 0.01), and decreased E% from pre to 0’ post intervention (p = 0.01) and maintained this improvement at 50’ post intervention (50’ post vs pre; p < 0.001). Children of closed skill sport significantly decreased their CP from pre to 50’ post intervention (50’ post vs pre; p = 0.001 and 50’ post vs 0’ post; p < 0.0001) and worsened their E% across the time (50’ post vs pre; p = 0.001 and 50’ post vs 0’ post; p < 0.0001). Boys showed significantly higher TN values than girls only in closed skill sport (p = 0.023). Finally, all girls of both open and closed skill sports significantly improved their CP from pre to 0’ post intervention (p = 0.04). Conclusion: Results of the study showed that open skill sport practice and training session positively affects children’s attentional performance.

Abstract In studies investigating haptic softness perception, participants are typically instructed to explore soft objects by indenting them with their index finger. In contrast, performance with other fingers has rarely been investigated. We wondered which fingers are used in spontaneous exploration and if performance differences between fingers can explain spontaneous usage. In Experiment 1 participants discriminated the softness of two rubber stimuli with hardly any constraints on finger movements. Results indicate that humans use successive phases of different fingers and finger combinations during an exploration, preferring index, middle, and (to a lesser extent) ring finger. In Experiment 2 we compared discrimination thresholds between conditions, with participants using one of the four fingers of the dominant hand. Participants compared the softness of rubber stimuli in a two-interval forced choice discrimination task. Performance with index and middle finger was better as compared to ring and little finger, the little finger was the worst. In Experiment 3 we again compared discrimination thresholds, but participants were told to use constant peak force. Performance with the little finger was worst, whereas performance for the other fingers did not differ. We conclude that in spontaneous exploration the preference of combinations of index, middle, and partly ring finger seems to be well chosen, as indicated by improved performance with the spontaneously used fingers. Better performance seems to be based on both different motor abilities to produce force, mainly linked to using index and middle finger, and different sensory sensitivities, mainly linked to avoiding the little finger.
