Résumé :

Background: Hand washing is one of the actions to clean hands and fingers to reduce nosocomial infections. Correct and appropriate nurse’s behavior in carrying out hand washing determines the adequate hand washing. Objective: This study purpose was to determine the perceptions of the nurse to implement five moments of hand washing. Methods: The study design used a description. Sampling used in this study was 20 respondents. The perceptions were measured by questionnaire. The statistical test data was analyzed using univariate. Results: The study results showed that the majority of respondents had a good perception (75%), while a small number of respondents had a fairly good perception (25%). Conclusion: The nurse's perception of carrying out the five moments of hand washing in the emergency room at Unipdu Medika Hospital was good. Hence, doing the correct hand washing procedure can prevent nosocomial infections.

Résumé :

Perception of one's body is related not only to the physical appearance of the body, but also to the neural representation of the body. The brain contains many body maps that systematically differ between right- and left-handed people. In general, the cortical representations of the right arm and right hand tend to be of greater area in the left hemisphere than in the right hemisphere for right-handed people, whereas these cortical representations tend to be symmetrical across hemispheres for left-handers. We took advantage of these naturally occurring differences and examined perceived arm length in right- and left-handed people. When looking at each arm and hand individually, right-handed participants perceived their right arms and right hands to be longer than their left arms and left hands, whereas left-handed participants perceived both arms accurately. These experiments reveal a possible relationship between implicit body maps in the brain and conscious perception of the body.

Résumé :

Hand hygiene is among the most important factors of infection control in healthcare settings. Healthcare workers are the primary source of hospital-acquired infection. We assessed the current state of hand hygiene knowledge, perception, and practice among the healthcare workers in Qassim, Saudi Arabia. In this cross-sectional study, we used the hand hygiene knowledge and perception questionnaire developed by the World Health Organization. Knowledge and perceptions were classified into good (80–100%), moderate (60–79%), and poor (<60% score). The majority of the healthcare workers had moderate knowledge (57.8%) and perception (73.4%) of hand hygiene. Males were less likely to have moderate/good knowledge compared to females (OR: 0.52, p < 0.05). Private healthcare workers were less likely (OR: 0.33, p < 0.01) to have moderate/good perceptions compared to the government healthcare workers. Healthcare workers who received training on hand hygiene were more likely to have good/moderate perception (OR: 3.2, p < 0.05) and to routinely use alcohol-based hand rubs (OR: 3.8, p < 0.05) than the ones without such training. Physicians are more likely (OR: 4.9, p < 0.05) to routinely use alcohol-based hand rubs than technicians. Our research highlighted gaps in hand hygiene knowledge, perception and practice among healthcare workers in Qassim, Saudi Arabia and the importance of training in this regard.

Résumé :

How we perceive our body is shaped by sensory experiences with our surrounding environment, as witnessed by poor performance in tasks during which participants judge with their hands crossed the temporal order between two somatosensory stimuli, one applied on each hand. This suggests that somatosensory stimuli are not only processed according to a somatotopic representation but also a spatiotopic representation of the body. We investigated whether the perception of stimuli occurring in external space, such as visual stimuli, can also be influenced by the body posture and somatosensory stimuli. Participants performed temporal order judgements on pairs of visual stimuli, one in each side of space, with their hands uncrossed or crossed. In Experiment 1, participants’ hands were placed either near or far from the visual stimuli. In Experiment 2, the visual stimuli were preceded, either by 60 ms or 360 ms, by tactile stimuli applied on the hands placed near the visual stimuli. Manipulating the time interval was intended to activate either a somatotopic or a spatiotopic representation of somatic inputs. We did not obtain any evidence for an influence of body posture on visual temporal order judgment, suggesting that body perception is less relevant for processing extrabody stimuli than the reverse.

Résumé :

Sensory perception for dexterous robotic hands is an active research area and recent progress in robotics. Effective dexterous manipulation requires robotic hands to accurately feedback their state or perceive the surrounding environment. This article reviews the state-of-the-art of sensory perception for dexterous robotic manipulation. Two types of sensors, such as intrinsic and extrinsic sensors, are introduced according to their function and layout in robotic hands. These sensors provide rich information to a robotic hand, which contains the posture, the contact information of objects, and the physical information of the environment. Then, a comprehensive analysis of perception methods including planning-level, control-level, and learning-level perceptions is presented. The information obtained from sensory perception can help robotic hands to make decisions effectively. Previously issued reviews mainly focus on the design of tactile senor, while we analyze and discuss the relationship among sensing, perception, and dexterous manipulation. Some potential research topics on sensory perception are also summarized and discussed.

Résumé :

Healthcare-associated infections (HAIs) is a great issue to concern in healthcare services because it accounts for prolonged hospital stay and may lead to morbidity or mortality. Proper hand hygiene behavior in the healthcare environment is indispensable in minimizing the risk of HAIs. This study aimed to identify the impact of hand hygiene education on healthcare workers' (HCWs) compliance, knowledge, and perception of hand hygiene at Atma Jaya Hospital, Jakarta, Indonesia. The compliance of hand hygiene was evaluated using the World Health Organization’s (WHO) five moments for hand hygiene as the reference. Data on hand hygiene knowledge and perception were collected using a translated version of the WHO’s hand hygiene knowledge questionnaire and hand hygiene perception questionnaire, respectively. Results showed a significant increase in compliance with hand hygiene after the online session’s intervention had been implemented, except hand hygiene compliance for the ‘after touching patient surroundings’ moment. There was also a significant increase in the HCWs' hand hygiene knowledge after the intervention. The HCWs' perceptions are also found to be positive even before the intervention. This study concludes that the HCWs' knowledge and compliance with hand hygiene at Atma Jaya Hospital increase significantly after an educational intervention had been conducted.

Objective This study conducted to assess health care practitioners’ knowledge and perceptions of hand hygiene among health professional working in clinical settings in Khartoum State - Sudan. with the specific objective of determining the association between their stance on hand hygiene and the general demographic characteristics of these health-care professionals. Methodology This is a cross-sectional study conducted between July and November 2017 using a modified form of WHO questionnaire for knowledge and perception that was included 22 items was sent online to health care workers via social media. The data obtained entered and analyzed by SPSS version 24. Chi-square and test of independence were used as a test of significance. A p-value of < 0.05 was considered statistically significant for all purposes. Result 437 hospital staff were responded to the questionnaire. (99.3%) was found to have good knowledge. 197(45.2%) had good perception and 239(54.8%) had fair perception. Formal hand hygiene training was found to have no association with knowledge levels of hand hygiene, but the fair perception was higher in the respondents who didn’t receive formal training. Conclusion The present study highlights the hand hygiene knowledge and perception. Most health care workers were found to have good knowledge, and the majority was found to have a fair perception. Formal hand hygiene training courses were found to have no association with knowledge but it may be reflected in practice. The importance of training sessions regarding hand hygiene was noticed in the perception level.

Résumé :

When using tools effects in body space and distant space often do not correspond or are even in conflict. The ideomotor principle holds that actors select, initiate and execute movements by activating the anticipatory codes of the movements’ sensory effects (Greenwald, 1970; James, 1890). These may be representations of body-related effects and/or representations of more distal effects. Previous studies have demonstrated that distant action effects dominate action control, while body-related effects are attenuated (e.g., Müsseler and Sutter, 2009). In two experiments, participants performed closed-loop controlled movements on a covered digitizer tablet to control a cursor on a monitor. Different gains perturbed the relation between hand and cursor amplitude, so that the hand amplitude varied and the cursor amplitude remained constant, and vice versa. Within a block the location of amplitude perturbation randomly varied (low predictability) or not (high predictability). In Experiment 1 both trajectories of hand and cursor followed the same linear path, in Experiment 2 a linear hand trajectory produced a curved cursor trajectory on the monitor. When participants were asked to evaluate their hand movement, they were extremely uncertain about their trajectories. Both, predictability of amplitude perturbation and shape of cursor trajectory modulated the awareness of one’s own hand movements. We will discuss whether the low awareness of proximal action effects originates from an insufficient quality of the humans’ tactile and proprioceptive system or from an insufficient spatial reconstruction of this information in memory.

Résumé :

We explored predictions of a scheme that views position and force perception as a result of measuring proprioceptive signals within a reference frame set by ongoing efferent process. In particular, this hypothesis predicts force illusions caused by muscle vibration and mediated via changes in both afferent and efferent components of kinesthesia. Healthy subjects performed accurate steady force production tasks by pressing with the four fingers of one hand (the task hand) on individual force sensors with and without visual feedback. At various times during the trials, subjects matched the perceived force using the other hand. High-frequency vibration was applied to one or both of the forearms (over the hand and finger extensors). Without visual feedback, subjects showed a drop in the task hand force, which was significantly smaller under the vibration of that forearm. Force production by the matching hand was consistently higher than that of the task hand. Vibrating one of the forearms affected the matching hand in a manner consistent with the perception of higher magnitude of force produced by the vibrated hand. The findings were consistent between the dominant and nondominant hands. The effects of vibration on both force drift and force mismatching suggest that vibration led to shifts in both signals from proprioceptors and the efferent component of perception, the referent coordinate and/or coactivation command. The observations fit the hypothesis on combined perception of kinematic-kinetic variables with little specificity of different groups of peripheral receptors that all contribute to perception of forces and coordinates. NEW & NOTEWORTHY We show that vibration of hand/finger extensors produces consistent errors in finger force perception. Without visual feedback, finger force drifted to lower values without a drift in the matching force produced by the other hand; hand extensor vibration led to smaller finger force drift. The findings fit the scheme with combined perception of kinematic-kinetic variables and suggest that vibration leads to consistent shifts of the referent coordinate and, possibly, of coactivation command to the effector.

Résumé :

This paper proposes a learning model that enables a robot to acquire a body image for parts of its body that are invisible to itself. The model associates spatial perception based on motor experience and motor image with perception based on the activations of touch sensors and tactile image, both of which are supported by visual information. The tactile image can be acquired with the help of the motor image, which is thought to be the basis for spatial perception, because all spatial perceptions originate in motor experiences. Based on the proposed model, a robot estimates invisible hand positions using the Jacobian between the displacement of the joint angles and the optical flow of the hand. When the hand touches one of the invisible tactile sensor units on the face, the robot associates this sensor unit with the estimated hand position. The simulation results show that the spatial arrangement of tactile sensors is successfully acquired by the proposed model.

Résumé :

Abstract BACKGROUND: Handwashing is the most important daily activity to keep microbial infections at a distance. Schoolchildren tend to acquire most of the infections by not following the protocol of frequent handwashing which leads to frequent illnesses and absenteeism from school on a regular basis. MATERIALS AND METHODS: A cross-sectional study was conducted by means of collecting hand swabs from 133 schoolchildren to estimate the extent of germs present. Furthermore, student's perception on hand hygiene was assessed by means of questionnaire. RESULTS: Among the schoolchildren, majority (68.4%) of them felt washing hands is important. Almost 56.4% of students washed their hands before eating lunch, but only 64.7% of them used soaps for cleaning their hands. Furthermore, hand swabs of 133 schoolchildren showed the growth of potential pathogens such as Staphylococcus aureus, Escherichia coli, Klebsiella spp., and Enterococcus faecalis. CONCLUSIONS: Hands of schoolchildren were found to be contaminated and measures to inculcate the habit of frequent handwashing with soap are essential.

Résumé :

AbstractBackground:Infectious complications are frequent among critically ill neonates. Hand hygiene is the leading measure to prevent healthcare-associated infections, but poor compliance has been repeatedly documented, including in the neonatal setting. Hand hygiene promotion requires a complex approach that should consider personal factors affecting healthcare workers' attitudes.Objective:To identify beliefs and perceptions associated with intention to comply with hand hygiene among neonatal healthcare workers.Methods:An anonymous, self-administered questionnaire (74 items) based on the theory of planned behavior was distributed to 80 neonatal healthcare workers to assess intention to comply, attitude toward hand hygiene, behavioral and subjective norm perceptions, and perception of difficulty to comply. Variables were assessed using multi-item measures and answers to 7-point bipolar scales. All multi-item scales had satisfactory internal consistency (alpha > 0.7). Multivariate logistic regression identified independent perceptions or beliefs associated with a positive intention to comply.Results:The response rate was 76% (61 of 80). Of the 49 nurses and 12 physicians responding, 75% believed that they could improve their compliance with hand hygiene. Intention to comply was associated with perceived control over the difficulty to perform hand hygiene (OR, 3.12; CI95, 1.12 to 8.70; P = .030) and a positive perception of how superiors valued hand hygiene (OR, 2.89; CI95, 1.08 to 7.77; P = .035).Conclusion:Our data highlight the importance of the opinions of superiors and a strong perceived controllability over the difficulty to perform hand hygiene as possible internal factors that may influence hand hygiene compliance.

Résumé :

Humans routinely use both of their hands to gather information about shape and texture of objects. Yet, the mechanisms of how the brain combines haptic information from the two hands to achieve a unified percept are unclear. This study systematically measured the haptic precision of humans exploring a virtual curved object contour with one or both hands to understand if the brain integrates haptic information from the two hemispheres. Bayesian perception theory predicts that redundant information from both hands should improve haptic estimates. Thus exploring an object with two hands should yield haptic precision that is superior to unimanual exploration. A bimanual robotic manipulandum passively moved the hands of 20 blindfolded, right-handed adult participants along virtual curved contours. Subjects indicated which contour was more “curved” (forced choice) between two stimuli of different curvature. Contours were explored uni- or bimanually at two orientations (toward or away from the body midline). Respective psychophysical discrimination thresholds were computed. First, subjects showed a tendency for one hand to be more sensitive than the other with most of the subjects exhibiting a left-hand bias. Second, bimanual thresholds were mostly within the range of the corresponding unimanual thresholds and were not predicted by a maximum-likelihood estimation (MLE) model. Third, bimanual curvature perception tended to be biased toward the motorically dominant hand, not toward the haptically more sensitive left hand. Two-handed exploration did not necessarily improve haptic sensitivity. We found no evidence that haptic information from both hands is integrated using a MLE mechanism. Rather, results are indicative of a process of “sensory selection”, where information from the dominant right hand is used, although the left, nondominant hand may yield more precise haptic estimates.

Résumé :

Hand hygiene is the act of cleaning one’s hands to remove oil, grease, microorganisms (or) other unwanted substances. Hand hygiene is considered as a primary practice which is used to reduce the risk and spread of infections to some extent. Washing hands with soap and water are considered the best way to remove germs. It helps in preventing diarrhea and uncomfortable intestinal diseases and reduces bacterial content on our hands. Health care professionals use alcohol-based hand disinfectant to prevent healthcare-associated infections and transmission of pathogens. Another widely used standard precautionary measure is wearing protective gloves. The main aim of this study is to assess the knowledge of hand hygiene practice of dental students. The present study is a cross-sectional study conducted among 100 dental students. The questionnaire consisted of 15 questions which were circulated among dental students through an online survey link. The questions were read carefully, and the answers were marked accordingly. The data was then collected and statistically analyzed. 93% of the participants think that hand hygiene is really necessary for day to day life. 88% of the participants think that maintaining proper hand hygiene helps us to be free from infections. The present-day dental students have very good knowledge about hand hygiene practice.

Résumé :

SUMMARYIn this paper we present a series of haptic exploratory procedures, or EPs, implemented for a multi-fingered, articulated, sensate robot hand. These EPs are designed to extract specific tactile and kinesthetic information from an object via their purposive invocation by an intelligent robotic system. Taken together, they form an active robotic touch perception system to be used both in extracting information about the environment for internal representation and in acquiring grasps for manipulation. The theory and structure of this robotic haptic system is based upon models of human haptic exploration and information processing.The haptic system presented utilizes an integrated robotic system consisting of a PUMA 560 robot arm, a JPL/Stanford robot hand, with joint torque sensing in the fingers, a wrist force/torque sensor, and a 256 element, spatially-resolved fingertip tactile array. We describe the EPs implemented for this system and provide experimental results which illustrate how they function and how the information which they extract may be used. In addition to the sensate hand and arm, the robot also contains structured-lighting vision and a Prolog-based reasoning system capable of grasp generation and object categorization. We present a set of simple tasks which show how both grasping and recognition may be enhanced by the addition of active touch perception.

Résumé :

We investigated whether hand guards (HG) influence the perception of pain and exertionduring the execution of a standardized task on high bar to induce forearm muscle fatigue aswell as a decline in grip strength after the task. Design: A cross-over study design wasemployed 15 healthy and physically active volunteers completed static bodyweight holds (8cycles of 20 second load in hang and 10 second rest), on a high bar. The exercise protocolwas performed with and without HG. Perception of pain and exertion during the task wererecorded. Peak handgrip force and explosive force parameters (i.e., rate of force development[RFD] and contractile impulse [CI] at 30 to 200 ms) were obtained from force-time curves.Peak force and explosive force parameters were normalized (i.e., POS/PRE) for statisticalanalysis. The use of a HG significantly attenuates pain perception (p < 0.05), with amoderate to large effect size (d = 0.52), but did not alter the perception of exertion during thetask, nor did it alter peak force, RFD, or CI. The use of HG reduces the perception of localpain during static holds. However, HG do not alter the perception of exertion during the tasknor do they alter the gripping force ability immediately afterwards. This research did notreceive any specific grant from funding agencies in the public, commercial, or not-for-profitsectors.

Résumé :

Our ability to perceive and discriminate textures is based on the processing of high-frequency vibrations generated on the fingertip as it scans across a surface. Although much is known about the processing of vibration amplitude and frequency information when cutaneous stimulation is experienced at a single location on the body, how these stimulus features are processed when touch occurs at multiple locations is poorly understood. We evaluated participants’ ability to discriminate tactile cues (100–300 Hz) on one hand while they ignored distractor cues experienced on their other hand. We manipulated the relative positions of the hands to characterize how limb position influenced cutaneous touch interactions. In separate experiments, participants judged either the frequency or intensity of mechanical vibrations. We found that vibrations experienced on one hand always systematically modulated the perception of vibrations on the other hand. Notably, bimanual interaction patterns and their sensitivity to hand locations differed according to stimulus feature. Somatosensory interactions in intensity perception were only marked by attenuation that was invariant to hand position manipulations. In contrast, interactions in frequency perception consisted of both bias and sensitivity changes that were more pronounced when the hands were held in close proximity. We implemented models to infer the neural computations that mediate somatosensory interactions in the intensity and frequency dimensions. Our findings reveal obligatory and feature-dependent somatosensory interactions that may be supported by both feature-specific and feature-general operations. NEW & NOTEWORTHY Little is known about the neural computations mediating feature-specific sensory interactions between the hands. We show that vibrations experienced on one hand systematically modulate the perception of vibrations felt on the other hand. Critically, interaction patterns and their dependence on the relative positions of the hands differed depending on whether participants judged vibration intensity or frequency. These results, which we recapitulate with models, imply that somatosensory interactions are mediated by feature-dependent neural computations.

This study investigates the concerns of 50 patients with ganglia and their reasons for primary care consultation and referral to a hand unit. Although a minority of patients sought advice and treatment because of pain, more (38%) were concerned about the cosmetic appearance and a significant number (28%) were concerned that their ganglion was a malignant growth. The general practitioners referred 70% of patients to the hand clinic for “excision of the ganglion” and 30% for further “advice and treatment”. However, 74% of patients were satisfied with aspiration of the ganglion and general advice.

Résumé :

Introduction: We aimed to investigate whether the provision of water, sanitation, and hand hygiene (WASH) interventions were associated with changes in hand hygiene compliance and perceptions of healthcare workers towards infection control. Methodology: The study was conducted from June 2017 through February 2018 among healthcare workers in two Northern districts of Ghana. Using a pretest-posttest design, we performed hand hygiene observations and perception surveys at baseline (before the start of WASH interventions) and post-intervention (midline and endline). We assessed adherence to hand hygiene practice using the WHO direct observation tool. The perception study was conducted using the WHO perception survey for healthcare workers. Study outcomes were compared between baseline, midline and endline assessments. Results: The hand hygiene compliance significantly improved from 28.8% at baseline through 51.7% at midline (n = 726/1404; 95% CI: 49.1-54.2%) to 67.9% at endline (n = 1000/1471; 95% CI: 65.6-70.3%). The highest increase in compliance was to the WHO hand hygiene moment 5 after touching patients surrounding (relative increase, 205%; relative rate, 3.05; 95% CI: 2.23-4.04; p < 0.0001). Post-intervention, the top three policies deemed most effective at improving hand hygiene practice were: provision of water source (rated mean score, n = 6.1 ± 1.4), participation in educational activities (rated mean score 6.0 ± 1.5); and hand hygiene promotional campaign (6.0 ± 1.3). Conclusion: Hand hygiene compliance significantly improved post-intervention. Sustaining good hand hygiene practices in low resource settings should include education, the provision of essential supplies, and regular hand hygiene audits and feedback.

Résumé :

Prolonged exposure to visual stimuli, or adaptation, often results in an adaptation “aftereffect” which can profoundly distort our perception of subsequent visual stimuli. This technique has been commonly used to investigate mechanisms underlying our perception of simple visual stimuli, and more recently, of static faces. We tested whether humans would adapt to movies of hands grasping and placing different weight objects. After adapting to hands grasping light or heavy objects, subsequently perceived objects appeared relatively heavier, or lighter, respectively. The aftereffects increased logarithmically with adaptation action repetition and decayed logarithmically with time. Adaptation aftereffects also indicated that perception of actions relies predominantly on view-dependent mechanisms. Adapting to one action significantly influenced the perception of the opposite action. These aftereffects can only be explained by adaptation of mechanisms that take into account the presence/absence of the object in the hand. We tested if evidence on action processing mechanisms obtained using visual adaptation techniques confirms underlying neural processing. We recorded monkey superior temporal sulcus (STS) single-cell responses to hand actions. Cells sensitive to grasping or placing typically responded well to the opposite action; cells also responded during different phases of the actions. Cell responses were sensitive to the view of the action and were dependent upon the presence of the object in the scene. We show here that action processing mechanisms established using visual adaptation parallel the neural mechanisms revealed during recording from monkey STS. Visual adaptation techniques can thus be usefully employed to investigate brain mechanisms underlying action perception.

Résumé :

Our ability to accurately discriminate information from one sensory modality is often influenced by information from the other senses. Previous research indicates that tactile perception on the hand may be enhanced if participants look at a hand (compared to a neutral object) and if visual information about the origin of touch conveys temporal and/or spatial congruency. The current experiment further assessed the effects of non-informative vision on tactile perception. Participants made speeded discrimination responses (digit 2 or digit 5 of their right hand) to supra-threshold electro-cutaneous stimulation while viewing a video showing a pointer, in a static position or moving (dynamic), towards the same or different digit of a hand or to the corresponding spatial location on a non-corporeal object (engine). Therefore, besides manipulating whether a visual contact was spatially congruent to the simultaneously felt touch, we also manipulated the nature of the recipient object (hand vs. engine). Behaviourally, the temporal cues provided by the dynamic visual information about an upcoming touch decreased reaction times. Additionally, a greater enhancement in tactile discrimination was present when participants viewed a spatially congruent contact compared to a spatially incongruent contact. Most importantly, this visually driven improvement was greater for the view-hand condition compared to the view-object condition. Spatially-congruent, hand-specific visual events also produced the greatest amplitude in the P50 somatosensory evoked potential (SEP). We conclude that tactile perception is enhanced when vision provides non-predictive spatio-temporal cues and that these effects are specifically enhanced when viewing a hand.

Résumé :

Background: Electronic hand hygiene monitoring systems (EHHMSs) are being increasingly utilized to improve hand hygiene outcomes. Following the implementation of an EHHMS at a large, academic medical center, an interdisciplinary team developed a web-based survey to gather information on employee’s perceptions and behaviors surrounding the EHHMS. Methods: In total, 1,273 complete responses were collected. Responses were analyzed using Stata version 16 statistical software with 2-tailed tests and .05 significance level. Multivariate logistic regression models were constructed to examine factors associated with negative perceptions of the EHHMS and of wearing the EHHMS radiofrequency identification (RFID) badge. Supporting qualitative analysis was performed using Atlas.ti version 9 software. Results: The general sentiment toward the monitoring system was neutral (38%) to negative (37%). The same was true for respondents’ sentiments toward wearing the RFID badge. Of respondents who interact with the system, 48% feel that the system does not capture hand hygiene data accurately. The EHHMS had limited influence on employee’s hand hygiene habits: 27% significant influence and 54% little-to-no influence. Respondents of younger age, those employed as a registered nurse, scientist, physician, or master’s level clinician, and those working at the satellite hospital were significantly more likely to have negative perceptions of the EHHMS. Negative perceptions were also significantly more likely among respondents familiar with the institution’s hand hygiene policy and those who had a negative opinion of seeing the hand hygiene data of others. Negative perceptions of the EHHMS RFID badge were significantly more likely among respondents of younger age, those employed as a registered nurse, scientist, physician, or master’s level clinician, those working at the satellite hospital, and those with a negative perception of seeing the hand hygiene data of others. Employment in a role providing direct patient care and those employed at the institution for >1 year were also significantly more likely to have a negative perception. Conclusions: Negative and neutral opinions dominate perceptions of the EHHMS considered in this analysis. Respondents expressed concerns with accuracy of the EHHMS data collection. The system’s limited influence is likely a result of limited familiarity, limited performance feedback, and employee frustration and concerns. These findings provide opportunities for improvement in future implementation of EHHMS. Based on these results, implementation of EHHMS would be best be supported by coordinated backing from administration and leadership, advanced planning and education, and frequent, effective communication. Additional research and evaluation are required to optimize implementation of electronic hand hygiene monitoring systems, with the goal of improving hand hygiene outcomes.Funding: NoneDisclosures: None

Résumé :

ABSTRACT Objective Hand sensory tests do not consider distinct physiological receptors, nor detect normal range variations concerning developmental or pathological changes. We developed an instrument with a set of tests with timing and scoring for assessing haptic perception, which is the interaction between sensory and motor systems, in surfaces exploration, by moving hands. Method Firstly, group meetings were set for test/manual conception and materials testing. The test/manual were submitted to 30 reviewers in 3 stages (10 reviewers on each stage). Results The Hand Haptic Perception Instrument (HHPI) evaluates hand sensorimotor performance on six domains: depression, elevation, texture, compressibility, weight (barognosis) and form perception. Each domain requires specific materials. Score ranges from 0 to 57, being 0 the worst rating. Conclusion This methodological process allowed the development of six domains and instructions to assess haptic perception. This version of HHPI is a pilot model. Further studies will determine reliability and normality ranges.

Résumé :

Introduction Simply inspecting one’s own body can reduce clinical pain and magnification of body parts can increase analgesia. Thus, body perceptions seem to play an important role for analgesia. Conversely, pain may also affect bodily perceptions. Therefore, we evaluated the effects of clinical and/or experimental pain on perceived hand size in fibromyalgia patients (FM) and healthy controls (HC). Methods To investigate the effects of chronic and/or acute pain on size perception we compared hand size estimates of 35 HC and 32 FM patients at baseline and during tonic mechanical pain stimuli applied to one ear lobe. Mechanical stimuli were adjusted for each individual pain sensitivity to achieve a rating of 4 ± 1 VAS (0–10) units. Photographs of each subject’s hands were digitally manipulated to produce a monotonic series of 5 images larger and 6 smaller than actual size which were then presented to the participants in ascending and descending order (total number of images: 12). Results FM and HC participants’ clinical pain ratings at baseline were 3.3 (3.1) and .3 (.8) VAS units, respectively. At baseline, FM participants selected significantly smaller hand images than HC as representative of their actual size (p < .02). During application of tonic experimental pain, the image size chosen to represent their actual hand size decreased significantly in FM participants and HC (p < .001) but this decrease was not different between groups (p > .05). Hand size estimates of FM participants correlated negatively with their clinical pain ratings (p < .04). Conclusion The decreased hand size perception of FM patients and HC was associated with their clinical and/or experimental pain, supporting the hypothesis that pain can result in visual body distortions.

Résumé :

The rubber-hand illusion provides a window into body representation and consciousness. It has been found that body-ownership extended to numerous hand-like objects. Interestingly, the vast majority of these objects were three-dimensional. We adopted this paradigm by using hand drawings to investigate whether rubber-hand illusion could be extended to two-dimensional hand samples, and we measured skin conductance responses and behavioural variables. The fact that this illusion extended to two-dimensional stimuli reveals the dominant role of top–down information on visual perception for body representation and consciousness.

Résumé :

Humans rely on their hands to perform everyday tasks. The hand is used as a tool, but also as the interface to ?sense? the world. Current prosthetic hands are based on sophisticated multi-fingered structures, and include many sensors which counterpart natural proprioceptors and exteroceptors. The sensory information is used for control, but not sent to the user of the hand (amputee). Grasping without sensing is not good enough. This research is part of the development of the sensing interface for amputees, specifically addressing the analysis of human perception while grasping. The goal is to determine the small number of preferred positions of sensors on the prosthetic hand. This task has previously been approached by trying to replicate a natural sensory system characteristic for healthy humans, resulting in a multitude of redundant sensors and basic inability to make the patient aware of the sensor readings on the subconscious level. We based our artificial perception system on the reported sensations of humans when grasping various objects without seeing the objects (obstructed visual feedback). Subjects, with no known sensory deficits, were asked to report on the touch sensation while grasping. The analysis included objects of various sizes, weights, textures and temperatures. Based on this data we formed a map of the preferred positions for the sensors that is appropriate for five finger human-like robotic hand. The final map was intentionally minimized in size (number of sensors).

Résumé :

We examined the haptic perception of orientations of a single bar throughout the horizontal plane using a verbal response: participants were to assign a number of minutes to the orientation of a bar defined with respect to the stimulus table. Performance was found to be systematically biased. Deviations were consistent with, yet much smaller than, those resulting from haptic motor matching tasks. The size and direction of the deviations were found to correlate with hand orientation, and not to depend on spatial location per se, suggesting a role for hand-centred reference frames in biasing performance. Delaying the response by 10 s led to a small improvement only of right-hand perceptions, indicating different hemispheric involvement in processes involved in retaining and/or recoding of haptic orientation information. Also the haptic oblique effect was found with the current verbal response. Importantly, it was affected neither by hand orientation nor by delay, suggesting that the oblique effect is independent of the aforementioned deviations in orientation perception.

Résumé :

The severity of hand–arm vibration syndrome (HAVS) is usually graded according to the Stockholm workshop scales. Although the Stockholm workshop scales are regarded the gold standard for assessing the severity of HAVS, they are based primarily on subjective symptoms. The aim of the present study was to explore the agreement between Stockholm workshop scales and the outcome from ten well-defined clinical tests commonly used in hand rehabilitation for assessment of hand function. One hundred and eleven vibration-exposed workers participated in the study. Ten objective tests of hand function and four questions on subjective hand symptoms were included. The results indicated that, out of these tests, perception of vibration, perception of touch/pressure and dexterity showed a moderate agreement with Stockholm workshop scales. Among specific questions on hand symptoms, cold intolerance and pain showed a high agreement with Stockholm workshop scales.
