Abstract
The aim of the present study was to compare the differences in joint coordination patterns and variability in the lower extremity between the first and second landing phases of the drop jump. Eighteen resistance-trained men (age: 22.8 ± 1.8 years) performed drop jumps from a height of 0.40 m. An eight-camera motion capture system was utilized to record kinematic trajectories. Modified vector coding technique and circular statistics were used to determine the coordination pattern and variability of the following joint couples during the first and second landings: hip frontal-knee frontal (HfKf), hip sagittal-knee frontal (HsKf), hip sagittal-knee sagittal (HsKs), knee frontal-ankle frontal (KfAf), knee sagittal-ankle frontal (KsAf), and knee sagittal-ankle sagittal (KsAs). Statistical differences in the distribution frequencies of coupling angles and variability between the dominant and nondominant limbs across the two landing phases were compared using two-way repeated analysis of variance and Wilcoxon rank-sum tests. During the second landing phase, the proportion of HsKs, KfAf, and KsAs showing in-phase coordination was reduced but the proportion of KfAf and KsAs showing proximal joint (knee) coordination was increased (p < .05). Significant differences in bilateral asymmetry were observed only for the HfKf and KfAf patients (p < .05). HsKs, KfAf, and KsAf varied considerably during the second landing phase (p < .05). Joint coordination patterns during the second landing phase of the drop jump differed considerably from those during the first landing phase, thereby increasing the risk of knee and ankle injuries.

Abstract
INTRODUCTION Individuals with traumatic brain injury (TBI) frequently need assistance to manage complex everyday activities. However, little is known about the types of cognitive assistance that can be used to facilitate optimal independence. A conversion mixed method study using video analysis was conducted to describe assistance provided by trained occupational therapists during three everyday tasks carried out in the participants' homes and surrounding environments. METHODS Forty-five people with moderate and severe TBI were tested by three occupational therapists using the Instrumental Activities of Daily Living Profile, an observation-based assessment that documents independence in complex everyday activities and the minimal assistance required to attain task goals. Using video analysis, difficulties experienced by the people with TBI during a meal preparation and grocery shopping task, and the cognitive assistance provided by the occupational therapists in response to these difficulties, were documented. Statistical analyses were also completed to identify the main difficulties and types of cognitive assistance provided during the evaluation, for the whole group and depending on their level of independence. RESULTS Nine types of cognitive assistance were used by occupational therapists, including implicit (stimulating thought processes), and more explicit assistance (cueing), to facilitate task performance. When needed, motivational assistance, which consisted of encouraging participants to think for themselves, was also used. Stimulating thought processes was mostly used to support goal formulation and planning, whereas cueing was used in numerous instances. Participants with lower levels of independence received more assistance of almost all types to support them. CONCLUSION Using these findings, training could be developed for caregivers and occupational therapists to support them in providing minimal and personalised cognitive assistance. Further research is needed to examine the extent to which all types of cognitive assistance are effective in helping various cognitive profiles of people with TBI attain optimal independence.

Abstract
PURPOSE Wheelchair users and people with disabilities have limited access to physical exercise due to various factors, including medical follow-up and training facilities. Although tele-exercise guided by experts has become a viable option, there is limited knowledge about the acute performance decrement (APD) resulting from remote training methods. The current cross-sectional study aimed to: (1) assess the APD of muscle resistance strength after three synchronous tele-exercise training methods in wheelchair users and (2) compare the training loads associated with each training method. MATERIALS AND METHODS Eighteen male and female wheelchair users who participated in tele-exercise strength practices were recruited. The participants performed a maximum resistance strength test by synchronous tele-assessment (push-up test, PUT) at baseline and immediately after three training methods: high-intensity interval training (HIIT), moderate-intensity continuous training (MICT) and sprint interval training (SIT). The primary outcome was the APD, which was measured by the percentage decrease in the number of repetitions of the PUT immediately after the training methods. RESULTS APD was observed for all three training methods, with no significant differences between them (-34.8%, -29.9% and -38.0% for MICT, SIT and HII, respectively), and presented a non-significant correlation with the training loads. HIIT had a significantly higher training load than MICT and SIT. CONCLUSIONS APD occurred in all training sessions, but did not correlate with training load, indicating that it is not an appropriate metric for comparison. Findings provide insight into APD response and highlight the need to consider multiple metrics when comparing training protocols.

Abstract
BACKGROUND While effective apprehensions of non-compliant suspects are central to public safety, the minimal force needed to transition a suspect from standing to the ground, vital for apprehension success, has not been established. OBJECTIVE To examine the technical-tactical behaviors of general duty police officers during simulated apprehensions and quantify the minimum force required to destabilize non-compliant suspects. METHODS Task simulations conducted with 91 officers were analyzed to identify common grappling movements, strikes, control tactics, and changes in body posture. A separate assessment of 55 male officers aimed to determine the minimum force required for destabilization in five body regions (wrist, forearm, shoulder, mid-chest, and mid-back). Data are presented as mean±standard deviation. RESULTS On average, apprehensions took 7.3±3.2 seconds. While all officers used grappling movements (100%) and the majority employed control tactics (75%), strikes were seldom used (4%). Apprehensions typically began with a two-handed pull (97%; Contact Phase), 55% then attempted an arm bar takedown, followed by a two-handed cross-body pull (68%; Transition/Control Phase), and a two-handed push to the ground (19%; Ground Phase). All officers began in the upright posture, with most shifting to squat (75%), kneel (58%), or bent (45%) postures to complete the apprehension. The minimum force required to disrupt balance differed across body regions (wrist: 54±12 kg; forearm: 49±12 kg; shoulder: 42±10 kg; mid-chest: 44±11 kg; mid-back: 30±7 kg, all P < 0.05), except between the shoulder and chest (P = 0.19). CONCLUSION These findings provide insights that can enhance the design and accuracy of future apprehension evaluations and inform the optimization of law enforcement physical employment standards.

Abstract
OBJECTIVE To investigate the correlation between changes in brain activity associated with working memory and assessment scales of memory scores in amnestic mild cognitive impairment (aMCI) before and after moxibustion therapy. METHODS aMCI patients were randomized into the moxibustion treatment (MT) group and the placebo moxibustion (PM) group. Each group received either moxibustion therapy or a placebo moxibustion for eight weeks. Neuropsychological performance and functional brain responses to a working memory task were assessed at baseline and at the end of treatment. Memory function was evaluated individually by the Rivermead behavioral memory test (RBMT), and working memory was assessed by the N-back task. RESULTS Compared with the PM group, RBMT score changes were significant ( < 0.05). In the MT group, the accuracy of the N-back texts increased compared with those before the intervention. After moxibustion intervention, the right insula, postcentral gyrus, precentral gyrus, superior temporal gyrus, thalamus, lingual gyrus, calcarine sulcus, posterior cingulate gyrus, middle frontal gyrus and anterior frontal gyrus were significantly activated (= 0.01, Cluster-level Family-Wise Error = 0.05). Pearson correlation analysis showed that the insula, lingual gyrus and posterior cingulate gyrus were associated with changes in N-back score. Spearman correlation analysis showed that the postcentral gyrus, superior temporal gyrus, thalamus, lingual gyrus, and posterior cingulate gyrus were correlated with RBMT score changes. CONCLUSION Moxibustion treatment improved memory in aMCI patients and was associated with the activation of the brain region of the insula, lingual gyrus, posterior cingulate gyrus, postcentral gyrus, superior temporal gyrus, and thalamus, which may be an important mechanism by which moxibustion improves the memory function.

Abstract
This is a cross-sectional descriptive study that investigates the mediating effect of humanism on the relationship between task performance and holistic nursing competence among clinical nurses. The participants were nurses with more than one year of work experience in general hospitals in South Korea, recruited using convenience sampling. A total of 227 data samples were collected. A self-reported questionnaire including the task performance competence scale, holistic nursing competence scale, and humanism scale was used for the survey. Data were analyzed using the t-test, analysis of variance, Pearson's correlation coefficients, and hierarchical multiple regression after checking for normal distribution. The results showed that task performance competence, holistic nursing competence, and humanism differed according to characteristics such as gender, age, educational level, marital status, position, length of career, and job and salary satisfaction. Task performance competence was positively correlated with holistic nursing competence and humanism. A positive correlation was also observed between holistic nursing competence and humanism. A partial mediating effect of humanism in the relationship between task performance competence and holistic nursing competence was confirmed. Thus, to increase nurses' holistic nursing competence, it is necessary to improve task performance competence and formulate a continuous and repetitive education program that includes humanism.

Abstract
PURPOSE To develop a new assessment form that is assessed by therapists for the performance of public transportation use for stroke survivors through content validation. MATERIALS AND METHODS The items for the tentative assessment form were selected using hierarchical clustering analysis on previous records of 76 field-based training sessions for public transportation use for stroke survivors. After the modification of the tentative form based on 6 months of clinical use, the final form was developed through content validation using the Delphi method by 71 therapists who had been working at the hospital for more than 2 years and had experience with training for public transportation use. RESULTS The Public Transportation use Assessment Form (PTAF) for stroke was successfully developed through three validation processes. It consists of four categories (plan for going out, mobility, using trains, and using buses) including 15 items that cover various tasks of public transportation use. The scoring for each was as follows: 3, independent; 2, requires supervision of verbal assistance; 1, requires assistance; and N, not applicable. CONCLUSION The PTAF, developed through content validation, could assess the ability of public transportation use, and identify specific problems for each stroke survivor in clinical setting.IMPLICATIONS FOR REHABILITATIONWe developed the Public Transportation use Assessment Form (PTAF) to assess the ability of stroke survivors to use public transportation.The PTAF could identify specific problems related to public transportation use for stroke survivors and aid in planning rehabilitation programs based on the results.The PTAF could share information about which task need support in public transportation use and could augment the hospital discharge plan.

Abstract
Coaches and psychologists can use time-motion analysis to elaborate specific interventions for female BJJ athletes, increasing specific training context and reducing unnecessary psychological and physical demands and injuries. Therefore, the present study aimed to analyze high-level BJJ female athletes in the 2020 Pan-American Games by comparing the weight categories on the time-motion analysis. The time-motion analysis (i.e., approach, gripping, attack, defensive actions, transition, mounting, guard, side control, and submissions) of 422 high-level female BJJ combats was divided and compared by weight category as follows: Rooster (n = 8), Light Feather (n = 18), Feather (n = 122), Light (n = 84), Middle (n = 74), Medium Heavy (n = 44), Heavy (n = 36), Super Heavy (n = 36), using p ≤ 0.05. The main results indicated that the Super heavyweight category [3.1 (5.8;119.9) s] had a shorter gripping time than other weight categories, p ≤ 0.05. In contrast, roosters [7.2 (3.5;64.6) s] had longer gripping, transition [14.0 (4.8;29.6) s], and attack time [76.2 (27.7, 93.2)] than the light feather, middlers, and heavier weight categories, p ≤ 0.05. These findings should be considered for the psychological interventions and training prescription.

Abstract
This study compared the time of female judo combat phases in international competitions between two Olympic cycles (2016; 2020) according to weight divisions (48 kg = 132; 52 kg = 72; 57 kg = 109; 63 kg = 96; 70 kg = 69; 78 kg = 106; >78 kg = 82; total = 666 combats/cycle). The behaviors of 1,332 high-level female judo combats were randomly observed over two Olympic cycles (2016 = 666; 2020 = 666) from the top 20 athletes in the world ranking by weight division. We performed time-motion analysis according to the combat phase and sequential judo actions (approach, gripping, attack, defense, groundwork, pause, and effort: pause ratio) considering the moment when the combat ended (Regular time = RT; Golden score = GS). The weight division groups were compared between Olympic cycles (2016; 2020), and p < 0.05 was defined as significant. The main results showed that 2020 athletes spent less time in the gripping (p = 0.005), attack (p < 0.001), defense (p < 0.001), groundwork (p<0.001) and pause (p = 0.002) phases than 2016 athletes. However, compared by the end-of-combat, 2020 female athletes spent less time in all combat phases for RT combats (p < 0.001), and more time in the approach phase for GS combats (p < 0.05) than in 2016. The 2016 weight divisions showed a higher diversity in the effort: pause ratio (2.5:1-3.4:1), whereas the 2020 weight divisions had values closer to each other (2.8,1-3:1). Analyzing each weight division separately and by the end-of-combat, the main results showed that (p < 0.05): 48, 63, 70, and 78 kg reduced the time in almost every phase of RT combat (except for: 63 kg = gripping and attack; 70 kg = approach and groundwork; 78 kg = approach); 48 and 57 kg increased the groundwork time in GS combats whereas 78 kg decreased; 52 kg and 78 kg increased the GS approach time. The temporal behavior of the combats changed between the Olympic cycles with different rules. These data must be considered to understand the characteristics of each group and to prescribe specialized training in female judo.

Abstract
Insomnia is associated with fatigue and poor driving performance, thus increasing the risk of traffic accidents. This study aimed to evaluate the effect of fatigue on driving in patients with chronic insomnia in a free-flow traffic scenario and car-following scenario, and to investigate the relationships between driving performance, cognitive function, and insomnia. The Trail Making Test (TMT), Stroop Color and Word Test (SCWT), Symbol Digit Modalities Test (SDMT), and Digit Span Test (DST) of 15 participants with mild-to-moderate chronic insomnia and 16 healthy participants were assessed. During the fatigue driving task, drivers completed simulated driving tasks under free-flow traffic and car-following scenarios. The mean speed (MS), mean acceleration (MA), mean lateral position (MLP), and standard deviation of lateral position (SDLP) were measured to assess driving performance. During fatigued tasks, the MA and MLP in the free-driving scenario were higher than those in the car-following scenario (P < 0.01), the SDLP was higher in the insomnia group than in the healthy group (P = 0.02), and the interaction effect was significantly different for MLP between the groups (P = 0.03). MS was negatively correlated with TMT score, SDMT score, and DST score, and positively correlated with time to complete TMT, errors in SCWT, and time to complete SCWT. SDLP was negatively correlated with DST score and positively correlated with time to complete SCWT. Furthermore, the insomnia group had poorer lateral vehicle control ability than the healthy group. The insomnia group had a more impaired driving performance in the free-driving scenario than in the car-following scenario. Drivers with impaired cognitive function exhibited impaired driving performance.

Abstract
Objective: Continued competency is poorly defined in emergency medical services (EMS), with no established method for verifying continued competency at a national level. The objective of this project was to refine understanding of continued competency for EMS clinicians in the U.S. and establish priorities for developing competency assessments.Methods: A panel of EMS managers, educators, medical directors, and experts in competency assessment, simulation, and certification used a modified Delphi technique to address two questions: "What is the content for continued competency in EMS that should be assessed or verified?" (content) and "How should continued competency of EMS clinicians be demonstrated?" (process) The Delphi process was conducted through electronic conferencing and survey software over a 6-month period. In round one, panelists responded to open-ended prompts and their contributions were analyzed and categorized into themes by independent reviewers. In round two, the panel rated theme importance using five-point Likert-type scales. In round three, the panel ranked their top 10 themes, and in round four, the panel selected the most important themes for each of the two questions through consensus-building discussions. Descriptive statistics and thematic analyses were performed with Excel and STATA 16.Results: Fourteen invited experts participated in all Delphi activities. The panel contributed 70 content and 35 process items from the original prompts. Following thematic analysis, these contributions were reduced to 21 and 14 unique themes, respectively. The final top five prioritized themes for content important for continued competency included 1) airway, respiration, and ventilation, 2) patient assessment, 3) pharmacology, 4) pediatrics, and 5) management of time critical disease progressions. The final top five prioritized themes for the processes for continued competency assessment included 1) assessments of evidence-based practice, 2) performance-based assessments, 3) combined knowledge and skill assessments, 4) performance improvement over time, and 5) frequent, short knowledge assessments.Conclusion: This modified Delphi process identified priorities for content and assessment, laying the groundwork for EMS continued competency at a national level. These findings can be leveraged by national task forces to develop transparent and consistent guidelines for systems that verify continued competency related to certification, licensure, and local credentialing.

Abstract
This study aimed to synthesize literature data on male judo combat time in international competitions between 2010 and 2019. The search was carried out from May 8th to June 11th, 2021, in electronic databases using the following keywords: ("technical-tactical" OR "time motion" OR "combat time") AND ("judo" OR "combat sports" OR "martial arts"). After the selection process, 8 articles were included in the systematic review and 7 in the meta-analysis. These studies analyzed 2,562 international male judo combats over the years 2010-2019. We observed that the average male judo combat time changed (2010 = 202.8; 2011-2012 = 304.8; 2016 = 237.4; 2018-2019 = 189.8 s) after each rule change (2010, 2013, 2017, and 2018). There was a significant difference between combats that ended up to the regular time and those that needed overtime (Golden Score: 2013 = 3% vs. 2018-2019 = 21%; p = 0.03). There were differences between 60 kg (p ≤ 0.019) and + 100 kg (p ≤ 0.04) categories and the others in 2011-2012. However, no significant difference was found between the combat time by weight division after the 2017 rule changes, although there are still differences in relation to the end of the combats (p < 0.001). There were significant changes in the male judo combat time with each rule change (2010, 2013, 2017, and 2018), and the data from the included studies point to a trend of homogeneity in the combat time spent between the weight divisions over the years, and an increase in the occurrence of Golden Score. More studies need to be carried out to identify the new temporal behaviors of athletes.

Abstract
BACKGROUND Retarded task-oriented gait, balance performance and increased fall risk are among the most debilitating problems in patients with diabetic polyneuropathy (DPN). The lower body positive pressure (LBPP) training was recently introduced in the field of rehabilitation, but evaluating the effects of the LBPP on gait, balance and fall risk in patients with DPN has not been thoroughly investigated. AIM The aim of this study was to evaluate the effect of LBPP treadmill training program on task-oriented gait, balance performance and fall risk in patients with DPN. DESIGN Single-blinded, randomized-controlled trial. SETTING Rehabilitative outpatient unit. POPULATION Sixty-two patients with DPN were randomly assigned into 5-groups; group-A (100% weight-bearing; N.=12), group-B (75% weight-bearing; N.=13), group-C (50% weight-bearing; N.=13), group-D (25% weight-bearing; N.=12) and group-E (control group; N.=12). METHODS The intervention groups (A, B, C, D) received moderate intensity aerobic exercise training (AET) program (30-45 minutes, 50-70% heart rate reserve) on the AlterG (AlterG, Inc., Fremont, CA, USA) treadmill for 12-weeks. Task-oriented gait, balance performance and the fall risk were evaluated at baseline (evaluation-1), after 12-weeks (evaluation-2) and 12-weeks poststudy cessation (evaluation-3; follow-up) for all groups using the Tinetti balance assessment tool. RESULTS At evaluation-2, there were significant "within-groups" increases in the balance, gait and fall risk scores. There were significant "between-groups" differences in the same evaluated variables, with the highest increases were in group-B (P<0.05). At evaluation-3, there was a decline in the mean values of the evaluated variables, but still significant increases in the mean values of balance, gait and fall risk compared to the baseline mean values. There were significant "between-groups" differences in all variables, with the highest increases were in group-B (P<0.05). CONCLUSIONS Moderate intensity LBPP treadmill training program can effectively improve task-oriented gait, balance performance, and fall risk scores in patients with DPN. The 25% off-loading weight percentage during the LBPP treadmill training program yielded the most favorable short and long-term improvements compared to the other weight off-loading percentages in patients with DPN. CLINICAL REHABILITATION IMPACT The LBPP aerobic training program is an effective rehabilitation procedure in patients with DPN especially when utilizing the 25% off-loading weight percentage during the LBPP treadmill training program.

Abstract
CONTEXT A detailed analysis of wheelchair basketball skills in beginner wheelchair basketball players (WBP) can provide practitioners with important indications regarding the selection and prospective development of potential sports talents. A comprehensive WBP evaluation can be very time consuming, mainly during the initial phases of the training processes, which could be a barrier in clinical and practical settings. Moreover, the large number and the turnover of beginner WBP attending rehabilitation centers make the applicability of field and strength tests unfeasible. OBJECTIVE To verify the relationships between the medicine ball throw (MBT) and wheelchair basketball mobility performance field tests and the shoulder and trunk peak torque in male and female beginner WBP. DESIGN Cross-sectional study. SETTING Rehabilitation Hospital Network, Paralympic Program. PARTICIPANTS Thirty-seven female and male beginner WBP. MAIN OUTCOMES MEASURES Participants performed wheelchair basketball field tests (speed, agility, strength, and power tests) and the maximum strength test in the isokinetic dynamometer. The outcomes were correlated with the MBT results. RESULTS The MBT presented significantly very high and perfect correlations with all wheelchair basketball field tests assessed (5-m sprint, 20-m sprint, and zig-zag agility test with and without a ball), and peak torque (R2 ranging from .810 to .995; P ≤ .05) for male and female athletes. CONCLUSIONS The MBT, a simple and feasible test, can be used for estimating and determining the wheelchair mobility performance of female and male beginner WBP. It is suggested to measure the distance of a 5-kg medicine ball thrown by athletes during training and testing routines to follow the players' progression.

Abstract
This study aimed to determine the impact of a soccer game on the creatine kinase (Ck) response and recovery and the specific Global Positioning System (GPS)-accelerometry-derived performance analysis during matches and comparing playing positions. A sample composed of 118 observations of 24 professional soccer teams of the Brazil League Serie A was recruited and classified according to playing positions, i.e., Left/Right Defenders (D = 30, age: 25.2 ± 5.8 years, height: 187 ± 5.5 cm, weight: 80 ± 5.8 kg), Offensive Midfielders (OM = 44, age: 25.1 ± 0.2 years, height: 177 ± 0.3 cm, weight: 73 ± 1.2 kg), Forwards (F = 9, age: 25.1 ± 0.2 years, height: 176.9 ± 4.3 cm, weight: 74.5 ± 2.1 kg), Left/Right Wingers (M = 23, age: 24.5 ± 0.5 years, height: 175 ± 1.1 cm, weight: 74 ± 4.4 kg), and Strikers (S = 12, age: 28 ± 0.2 years, height: 184 ± 1.0 cm, weight: 80 ± 1.4 kg). Blood Ck concentration was measured pre-, immediately post-, and 24 h postgame, and the GPS-accelerometry parameters were assessed during games. Findings demonstrated that Ck concentrations were higher at all postgame moments when compared with pregame, with incomplete recovery markers being identified up to 24 h after the game (range: 402–835 U/L). Moreover, Midfielders (108.6 ± 5.6 m/min) and Forwards (109.1 ± 8.3 m/min) had a higher relative distance vs. other positions (100.9 ± 10.1 m/min). Strikers [8.2 (8.1, 9.05) load/min] and Defenders [8.45 (8, 8.8) load/min] demonstrated lower load/min than Wingers [9.5 (9.2, 9.8) load/min], Midfielders [10.6 (9.9, 11.67) load/min], and Forwards [11 (10.65, 11, 15) load/min]. These results could be used to adopt specific training programs and recovery strategies after match according to the playing positions.

Abstract
PURPOSE To determine the effects of a Home-based multimodal exercise program for older people with Alzheimer's disease (AD-HOMEX) on muscle strength, mobility, the risk of falls and functioning. MATERIALS AND METHODS A trial with a blinded assessor was conducted involving 40 older people with mild to moderate AD randomized to an intervention group (IG) or control group (CG). The IG participated in a 16-week protocol with three 60-minute sessions per week. The sessions were performed at the participant's home by a physiotherapist and involved progressive individualized physical exercises. Muscle strength (5X Sit-to-Stand Test [5XSTS], 30-Second Chair Stand test, isokinetic and hand-grip dynamometer), functioning (DAFS-R and ADL-Q), mobility and the risk of falls (TUG) were assessed at baseline and after training. Intention-to-treat analysis was adopted. RESULTS There was a significant group-evaluation time interaction for the 5XSTS (p = 0.011). The IG demonstrated an improved performance on the 5XSTS (p = 0.020) and a reduced risk of falls (p = 0.000), whereas the CG exhibited a worse functional limitation (p = 0.008) after 16 weeks. The CG had an increased risk of falls (p = 0.006) and worse performance on the ADL-Q (p = 0.047) at the follow-up evaluation. An improvement in the IG and worsening in the CG were found regarding transition patterns between severity levels of functional limitation based on the ADL-Q. CONCLUSIONS Home-based physical exercise for older people with mild to moderate AD is an effective strategy that decreases the risk of falls and improves strength and functioning.

Abstract
This study explored which technical and physical attributes could predict superior and/or safe landing performance when surfers performed variations of a simulated aerial task. Fourteen surfers (age 20.6 ± 5.7 years, height 178.1 ± 9.50 cm, mass 70.6 ± 10.8 kg) had their lower limb mobility, squat jump, countermovement jump, and drop-and-stick landing performance assessed. Performance of two aerial variations (Frontside Air (FA) and Frontside Air Reverse (FAR)) was also measured, with variables relating to technical performance (critical feature and subjective ratings) and potential injury risk (relative total peak landing force and loading rates) collected. Multiple linear regressions were used to predict performance of both aerial variations based on a subset of independent variables. Four models could predict performance. Predicted technical capability in the FAR was mostly influenced by lead limb hip extension and lead limb knee flexion range of motion. Potential injury risk when surfers perform an FA and FAR was predicted to be mitigated by increasing lead ankle dorsiflexion range of motion, as well as trail hip extensor mobility to reduce the relative total peak force experienced when landing the FA. These simple outcome measures could be routinely assessed to ensure successful and safe aerial landings in surfing.

Abstract
Understanding decision-making in complex and dynamic environments is relevant for designing strategies targeting safety improvements and error rate reductions. However, studies evaluating brain dynamics in realistic situations are scarce in the literature. Given the evidence that specific microstates may be associated with perception and attention, in this work we explored for the first time the application of the microstate model in an ecological, dynamic and complex scenario. More specifically, we evaluated elite helicopter pilots during engine-failure missions in the vicinity of the so called "dead man's curve," which establishes the operational limits for a safe landing after the execution of a recovery maneuver (autorotation). Pilots from the Brazilian Air Force flew a AS-350 helicopter in a certified aerodrome and physiological sensor data were synchronized with the aircraft's flight test instrumentation. We assessed these neural correlates during maneuver execution, by comparing their modulations and source reconstructed activity with baseline epochs before and after flights. We show that the topographies of our microstate templates with 4, 5, and 6 classes resemble the literature, and that a distinct modulation characterizes decision-making intervals. Moreover, the source reconstruction result points to a differential activity in the medial prefrontal cortex, which is associated to emotional regulation circuits in the brain. Our results suggest that microstates are promising neural correlates to evaluate realistic situations, even in a challenging and intrinsically noisy environment. Furthermore, it strengthens their usage and expands their application for studying cognition under more realistic conditions.

Abstract
This study aimed to perform motor action and biomechanical analysis of techniques in female judo athletes separated by weight categories of 638 female bouts (103 extra lightweight <48 kg, 140 half lightweight 48>52 kg, 65 lightweight 52>57 kg, 73 half middleweight 57>63 kg, 77 middleweight 63>70 kg, 80 half heavyweight 70>78 kg and 60 heavyweight >78 kg). All bouts were analyzed following the phases of approach, gripping, defensive action, attack, also biomechanical analysis of techniques and groundwork was performed (p ≤ .05). Results indicated that lightweight athletes presented lower attempts to grip, right collar grip and left collar grip frequencies than other categories. Extra lightweight judokas presented lower right back grip and left back and sleeve grip frequencies as well as lower occurrence of techniques with arm and leg lever scored than half lightweight athletes, while half lightweight athletes demonstrated higher frequency of techniques with waist lever variable scored than lightweight ones. These findings should be considered for training prescription.

Abstract
AIMS To identify the determinants of the quality of nursing care from the perceptions of nursing personnel. BACKGROUND The quality of nursing care is often measured with standards, expectations, satisfaction and outcomes, but in developing countries, it relies mostly on negative indicators. METHODS A descriptive qualitative study was used. Semi-structured interviews based on the critical incident technique were conducted with a convenience sample of 136 nursing personnel who told 225 stories. RESULTS Seven quality determinants of nursing care were identified as follows: standard of care, triage and assessment, emergency care, communication with the patient or family, communication with colleagues, multidisciplinary teamwork and helping colleagues. The most important one was the standard of care. CONCLUSION Quality nursing care is based on the degree of excellence nursing personnel show with regard to their competences in technical care, communication and teamwork. A key attribute of quality nursing care is defined by the related standards, and the focus is mostly on the nursing care process. IMPLICATIONS FOR NURSING MANAGEMENT These findings can increase awareness of the determinants of nursing quality and the qualities of the nursing personnel involved and can help managers to evaluate nursing practice, select new employees and organise teams.

Abstract
Introduction. Connecting multiple haptic devices in a master-slave fashion enables us to deliver kinesthetic (haptic) feedback from 1 person to another. This study examined whether inter-user feedback delivered from an expert to a novice would facilitate skill acquisition of the novice in learning laparoscopic surgery and expedite it compared to traditional methods. Methods. We recruited fourteen novices and divided them into 1 of 2 training groups with 6 half-hour training sessions. The task was precision cutting adopted from one of the tasks listed in Fundamentals of Laparoscopic Surgery using laparoscopic instruments. In the haptic feedback group (haptic), 8 subjects had the chance to passively feel an expert's performance before they started to practice in each training session. In the self-learning group (control), 6 subjects watched a video before practicing. Each session was video recorded, and task performance was measured by task completion time, number of grasper adjustments, and instrument crossings. Cutting accuracy, defined as the percentage of deviation of the cutting line from the predefined line, was analyzed via computer analysis. Results. Results show no significant difference among performance measures between the 2 groups. Participants performed similarly when practicing alone or with periodic haptic feedback. Discussion. Further research will be needed for improving our way of integrating between-person haptic feedback with skills training protocol.

Abstract
Background Operational failures, defined as inadequacies or errors in the information, supplies, or equipment needed for patient care, are known to be highly consequential in hospital environments. Despite their likely relevance for GPs’ experiences of work, they remain under-explored in primary care. Aim To identify operational failures in the primary care work environment and to examine how they influence GPs’ work. Design and setting Qualitative interview study in the East of England. Method Semi-structured interviews were conducted with GPs (n = 21). Data analysis was based on the constant comparison method. Results GPs reported a large burden of operational failures, many of them related to information transfer with external healthcare providers, practice technology, and organisation of work within practices. Faced with operational failures, GPs undertook ‘compensatory labour’ to fulfil their duties of coordinating and safeguarding patients’ care. Dealing with operational failures imposed significant additional strain in the context of already stretched daily schedules, but this work remained largely invisible. In part, this was because GPs acted to fix problems in the here-and-now rather than referring them to source, and they characteristically did not report operational failures at system level. They also identified challenges in making process improvements at practice level, including medicolegal uncertainties about delegation. Conclusion Operational failures in primary care matter for GPs and their experience of work. Compensatory labour is burdensome with an unintended consequence of rendering these failures largely invisible. Recognition of the significance of operational failures should stimulate efforts to make the primary care work environment more attractive.

Abstract
PURPOSE Mothers of infants hospitalized in neonatal intensive care units (NICUs) need to be recognized as essential partners of the care team as their presence and involvement are key to infants' health and developmental outcomes. Addressing mothers' perceived needs is beneficial for the improvement of supportive nursing care; however, little qualitative research on their unmet needs has been conducted in South Korea. This study assessed mothers' perspectives on their NICU experiences and their unmet needs within the South Korean cultural context. METHOD A cross-sectional, multicentered, secondary analysis study was conducted using the written responses to an open-ended questionnaire. Of the 344 NICU-experienced mothers, 232 throughout South Korea (seven cities and five provinces) voluntarily completed the questionnaire via smartphone-based or web-based surveys. Their narrative responses were analyzed using thematic content analysis guided by the critical incident technique. RESULTS Four themes emerged. NICU-experienced mothers of preterm infants referred to the "family-friendly environment" (16.4%) as a positive experience. The greatest unmet need was "relationship-based support" (58.2%), followed by "information and education-based support" (20.0%) and "system-level challenges" (5.4%). CONCLUSION The importance of creating a family-friendly NICU environment should be emphasized by ensuring 24-hour unrestricted access and encouraging active parental involvement in infant care, as well as actively supporting NICU families through supportive words and actions. The assurance of antiinfection management and better staffing levels should be fundamentally guaranteed to NICU staff.

Abstract
Up to 81% of individuals who are fluent in sign language (signers) report pain. Non-native signers (with non-signing, non-deaf parents) report greater pain than natives (≥1 signing, deaf parent). The goal of this study was to develop a composite measure of injury risk (the modified Strain Index for signers) based on previously identified biomechanics unique to signers and examine scores across sub-groups of natives and non-natives. Non-natives were hypothesized to have greater pain and higher composite scores than natives. Ten natives and 15 non-natives used a numeric scale to rate pain while signing. Measures included 'micro' rests, muscle activation, ballistic signing, non-neutral joint angle, and work envelope. Descriptive statistics were used to create categorical ratings and backward elimination multiple linear regression to establish rank order of the biomechanical tasks. Participant performance was rated, and the product of the multipliers across tasks created a score. Pain intensity was associated with the composite score (r = 0.46; p = 0.02), however there was no difference between natives (score = 13.39 ± 3.1) and non-natives (score = 19.55 ± 4.7; p = 0.34). This work presents an approach to incorporate multiple biomechanical factors into a single, composite measure unique to signers, however further evidence-based adjustments are needed to enhance its robustness.

Abstract
This study aimed to evaluate the degree to which transcutaneous electrical stimulation (ES) enhanced recovery following a simulated water rescue. Twenty-six lifeguards participated in this study. The rescue consisted of swimming 100 m with fins and rescue-tube: 50 m swim approach and 50 m tow-in a simulated victim. Blood lactate clearance, rated perceived effort (RPE), and muscle contractile properties were evaluated at baseline, after the water rescue, and after ES or passive-recovery control condition (PR) protocol. Tensiomiography, RPE, and blood lactate basal levels indicated equivalence between both groups. There was no change in tensiomiography from pre to post-recovery and no difference between recovery protocols. Overall-RPE, legs-RPE and arms-RPE after ES (mean ± SD; 2.7 ± 1.53, 2.65 ± 1.66, and 2.30 ± 1.84, respectively) were moderately lower than after PR (3.57 ± 2.4, 3.71 ± 2.43, and 3.29 ± 1.79, respectively) (p = 0.016, p = 0.010, p = 0.028, respectively). There was a significantly lower blood lactate level after recovery in ES than in PR (mean ± SD; 4.77 ± 1.86 mmol·L-1 vs. 6.27 ± 3.69 mmol·L-1; p = 0.045). Low-frequency ES immediately after a water rescue is an effective recovery strategy to clear out blood lactate concentration.

Abstract
OBJECTIVE To diagnose egocentric neglect after stroke, the spatial bias of performance on cancellation tasks is typically compared to a single cutoff. This standard procedure relies on the assumption that the measurement error of cancellation performance does not depend on non-spatial impairments affecting the total number of cancelled targets. Here we assessed the impact of this assumption on false-positive diagnoses. METHOD We estimated false positives by simulating cancellation data using a binomial model. Performance was summarised by the difference in left and right cancelled targets (R-L) and the Centre of Cancellation (CoC). Diagnosis was based on a fixed cutoff versus cutoffs adjusted for the total number of cancelled targets and on single test performance versus unanimous or proportional agreement across multiple tests. Finally, we compared the simulation findings to empirical cancellation data acquired from 651 stroke patients. RESULTS Using a fixed cutoff, the rate of false positives depended on the total number of cancelled targets and ranged from 10% to 30% for R-L scores and from 10% to 90% for CoC scores. The rate of false positives increased even further when diagnosis was based on proportional agreement across multiple tests. Adjusted cutoffs and unanimous agreement across multiple tests were effective at controlling false positives. For empirical data, fixed versus adjusted cutoffs differ in estimation of neglect prevalence by 13%, and this difference was largest for patients with non-spatial impairments. CONCLUSIONS Our findings demonstrate the importance of considering non-spatial impairments when diagnosing neglect based on cancellation performance.

Abstract
This brief research report showed technical-tactical behaviors of male and female judo cadets during combats, comparing the frequency and time of judo combat actions, techniques and penalties. The data was composed for 3,240 sequential technical-tactical behavior analysis from 108 female and 300 male cadet combats recorded of public judo championships. Combat, standing combat moments, approach action, gripping action, attack, groundwork actions and pause moment were observed and determinant technical-tactical behaviors (frequencies of actions, penalties and type of attacks) analysis were done with FRAMI software, followed by Mann-Whitney and Student's t-test, p ≤ 0.05. Our main results indicated that male cadets with 58.66s ± 50.26s demonstrated longer gripping action than female with 38.44s ± 30.44s, as standing combat (tachi-waza) had differences between male with 96.8s ± 72s and female athletes with 75.85s ± 56.97s. Moreover, male cadets had higher sacrifice techniques (sutemi-waza) actions than female athletes. This information could be used to a best performance associated with "psyching-up" as much as it could be used on physical training and technical-tactical ability of female and male cadets.

Abstract
Background: An increasing lifespan and the resulting change in our expectations of later life stages are dependent on a good health state. This emphasizes the importance of the development of strategies to further strengthen healthy aging. One important aspect of good health in later life stages is sustained skilled motor function. Objective: Here, we tested the effectiveness of robotic upper limb motor training in a game-like scenario assessing game-based learning and its transfer potential. Methods: Thirty-six healthy participants (n = 18 elderly participants, n = 18 young controls) trained with a Pacman-like game using a hand-held Cellulo robot on 2 consecutive days. The game-related movements were conducted on a printed map displaying a maze and targets that had to be collected. Gradually, the task difficulty was adjusted between games by modifying or adding different game elements (e.g., speed and number of chasing ghosts, additional rules, and haptic feedback). Transfer was assessed by scoring simple robot manipulation on two different trajectories. Results: Elderly participants were able to improve their game performance over time [t(874) = 2.97, p < 0.01]. The applied game elements had similar effects on both age groups. Importantly, the game-based learning was transferable to simple robot manipulation that resembles activities of daily life. Only minor age-related differences were present (smaller overall learning gain and different effects of the wall-crash penalty rule in the elderly group). Conclusions: Gamified motor training with the Cellulo system has the potential to translate into an efficient and relatively low-cost robotic motor training tool for promoting upper limb function to promote healthy aging.

Abstract
OBJECTIVES The assessment of situation awareness (SA), team performance and task performance in a simulation training session requires reliable and feasible measurement techniques. The objectives of this study were to test the Airways-Breathing-Circulation-Disability-Exposure (ABCDE) checklist and the Team Emergency Assessment Measure (TEAM) for inter-rater reliability, as well as the application of Situation Awareness Global Assessment Technique (SAGAT) for feasibility and internal consistency. DESIGN Methodological approach. SETTING Data collection during team training using full-scale simulation at a university clinical training centre. The video-recorded scenarios were rated independently by four raters. PARTICIPANTS 55 medical students aged 22-40 years in their fourth year of medical studies, during the clerkship in anaesthesiology and critical care medicine, formed 23 different teams. All students answered the SAGAT questionnaires, and of these students, 24 answered the follow-up postsimulation questionnaire (PSQ). TEAM and ABCDE were scored by four professionals. MEASURES The ABCDE and TEAM were tested for inter-rater reliability. The feasibility of SAGAT was tested using PSQ. SAGAT was tested for internal consistency both at an individual level (SAGAT) and a team level (Team Situation Awareness Global Assessment Technique (TSAGAT)). RESULTS The intraclass correlation was 0.54/0.83 (single/average measurements) for TEAM and 0.55/0.83 for ABCDE. According to the PSQ, the items in SAGAT were rated as relevant to the scenario by 96% of the participants. Cronbach's alpha for SAGAT/TSAGAT for the two scenarios was 0.80/0.83 vs 0.62/0.76, and normed χ² was 1.72 vs 1.62. CONCLUSION Task performance, team performance and SA could be purposefully measured, and the reliability of the measurements was good.

Abstract
This study compared grappling motor actions of male mixed martial arts (MMA) athletes considering outcome types from Ultimate Fighting Championship ( UFC) bouts. A validated protocol of technical-tactical analysis was utilized as in previous studies addressing MMA performance analysis, and Kruskall Wallis and U Mann-Whitney tests were applied to compare effects of types of outcome decisions (Split vs. Unanimous Decision vs. Knockout-KO/Technical-knockout-TKO vs. Submission). Unanimous Decision showed higher frequencies of takedowns attempted/round than KO/TKO and Submission outcomes (p ≤ 0.05; 1.9 ± 1.9 vs. 1.3 ± 1.4 vs. 1.0 ± 1.1 attempts). Bouts with Split Decision demonstrated higher takedowns/round than bouts ended by Submission (p = 0.048; 0.4 ± 0.7 vs. 0.2 ± 0.6 attempts). TKO/KO showed lower values of sweeps/round (p = 0.008, 0.0 ± 0.0 vs. 0.1 ± 0.3 attempts) and takedowns attempted/round (p = 0.014, 1.3 ± 1.4 vs. 2.0 ± 1.6 attempts) than bouts ending by Split Decision. The Submission outcome showed a higher frequency of submissions attempted/round than KO/TKO and Unanimous Decision (p ≤ 0.041, 0.3 ± 0.7 vs 0.2 ± 0.5 vs 0.2 ± 0.5). These results show a large specificity in the type of grappling attack/situation according to the strategy to end the combat. These results also show that the grappling strategy and tactics are variable depending on the strengths and weaknesses of the athletes, and can be used by coaches and athletes to develop specific training programs.

Abstract
Background Recent advances in technology have reopened an old debate on which sectors will be most affected by automation. This debate is ill served by the current lack of detailed data on the exact capabilities of new machines and how they are influencing work. Although recent debates about the future of jobs have focused on whether they are at risk of automation, our research focuses on a more fine-grained and transparent method to model task automation and specifically focus on the domain of primary health care. Objective This protocol describes a new wave of intelligent automation, focusing on the specific pressures faced by primary care within the National Health Service (NHS) in England. These pressures include staff shortages, increased service demand, and reduced budgets. A critical part of the problem we propose to address is a formal framework for measuring automation, which is lacking in the literature. The health care domain offers a further challenge in measuring automation because of a general lack of detailed, health care–specific occupation and task observational data to provide good insights on this misunderstood topic. Methods This project utilizes a multimethod research design comprising two phases: a qualitative observational phase and a quantitative data analysis phase; each phase addresses one of the two project aims. Our first aim is to address the lack of task data by collecting high-quality, detailed task-specific data from UK primary health care practices. This phase employs ethnography, observation, interviews, document collection, and focus groups. The second aim is to propose a formal machine learning approach for probabilistic inference of task- and occupation-level automation to gain valuable insights. Sensitivity analysis is then used to present the occupational attributes that increase/decrease automatability most, which is vital for establishing effective training and staffing policy. Results Our detailed fieldwork includes observing and documenting 16 unique occupations and performing over 130 tasks across six primary care centers. Preliminary results on the current state of automation and the potential for further automation in primary care are discussed. Our initial findings are that tasks are often shared amongst staff and can include convoluted workflows that often vary between practices. The single most used technology in primary health care is the desktop computer. In addition, we have conducted a large-scale survey of over 156 machine learning and robotics experts to assess what tasks are susceptible to automation, given the state-of-the-art technology available today. Further results and detailed analysis will be published toward the end of the project in early 2019. Conclusions We believe our analysis will identify many tasks currently performed manually within primary care that can be automated using currently available technology. Given the proper implementation of such automating technologies, we expect considerable staff resources to be saved, alleviating some pressures on the NHS primary care staff.

Abstract
The present study aimed to compare pacing and decision making of athletes competing in judo, with particular attention paid to effort-pause ratios occurring in the championship phases of the Olympic Games and non-Olympic Games. The sample was composed of 53,403 sequential actions analyzed during 611 performances of the non-Olympic Games (eliminatory n = 330, quarterfinals n = 60, semi-final n = 88, repechage n = 21, third place playoff n = 26, and final n = 79) and 163 from the Olympic Games (eliminatory n = 71, quarterfinals n = 13, semi-final n = 26, repechage n = 20, third place playoff n = 24, and final n = 14). The analysis of effort-pause ratios included separating bouts into states of approach, gripping, attack, groundwork and pause, according to frequency and time. A Markov multi-state model and analysis of variance were applied (p ≤ 0.05). Approach time presented differences of the eliminatory Olympic Games (7.3 ± 3.2 s) versus final non-Olympic Games (6.0 ± 2.2s), and the third place playoff Olympic Games (8.1 ± 2.3 s) versus semi-final (6.2 ± 2.4 s) and third place playoff (5.9 ± 2.1 s) of the non-Olympic Games, and the semi-final Olympic Games (8.6 ± 2.3 s) versus eliminatory (6.5 ± 2.3 s), quarter-finals (6.5 ± 1.7 s), semi-final (6.2 ± 2.4 s), repechage (6.2 ± 2.2 s), third place playoff (5.9 ± 2.1 s), and final (6.0 ± 2.0 s) of the non-Olympic Games. Pause time presented differences of the semi-final Olympic Games (6.8 ± 2.1 s) versus eliminatory (5.1 ± 3.1 s). The present data suggest a focus on pacing strategy during championship phases, which mimic the requirements of judo combats.

Abstract
Basketball is a team sport, where fundamental skills - fundamentals - are key determinants for success. Jump-shot (JS) is a basketball fundamental used frequently during game. It is interesting to spread light on the relationship between effort intensity and JS ability. Study aim was to investigate different heart rates (HRs) effect on JS accuracy (JS%) in 22 male youth (15.7 ± 0.9 years) players. Experimental sessions consisted of 10 JSs from five spots 5 m from basket at three different HRs: rest (0HR) and after warm-up (50% [50HR] and 80% maximal HR [80HR]). Analysis of variance showed differences in JS% over sessions (42.27 ± 14.78% at 0HR, 38.18 ± 10.53% at 50HR, and 30.00 ± 16.62% at 80HR; P = 0.018). Least significant difference test did not show any significant difference between 50HR and 0HR JS% (P = 0.343), while 80HR elicited significantly lower values with respect to both 0HR (P = 0.006) and 50HR (P = 0.049). Study provided practical indications on maintaining high JS%: preliminary warm-up (even if injury-protecting) does not improve JS%, because between 50HR and 0HR difference was not significant; and 80HR significantly decreases JS%. Therefore, to maximize JS scoring players have to rest as much as possible during game-play pauses, and coaches should manage timeouts and substitutions accordingly, especially during final minutes of close games.

Abstract
Background Increasingly, eHealth involves health data visualizations to enable users to better understand their health situation. Selecting efficient and ergonomic visualizations requires knowledge about the task that the user wants to carry out and the type of data to be displayed. Taxonomies of abstract tasks and data types bundle this knowledge in a general manner. Task-data taxonomies exist for visualization tasks and data. They also exist for eHealth tasks. However, there is currently no joint task taxonomy available for health data visualizations incorporating the perspective of the prospective users. One of the most prominent prospective user groups of eHealth are older adults, but their perspective is rarely considered when constructing tasks lists. Objective The aim of this study was to construct a task-data taxonomy for health data visualizations based on the opinion of older adults as prospective users of eHealth systems. eHealth experts served as a control group against the bias of lacking background knowledge. The resulting taxonomy would then be used as an orientation in system requirement analysis and empirical evaluation and to facilitate a common understanding and language in eHealth data visualization. Methods Answers from 98 participants (51 older adults and 47 eHealth experts) given in an online survey were quantitatively analyzed, compared between groups, and synthesized into a task-data taxonomy for health data visualizations. Results Consultation, diagnosis, mentoring, and monitoring were confirmed as relevant abstract tasks in eHealth. Experts and older adults disagreed on the importance of mentoring (χ24=14.1, P=.002) and monitoring (χ24=22.1, P<.001). The answers to the open questions validated the findings from the closed questions and added therapy, communication, cooperation, and quality management to the aforementioned tasks. Here, group differences in normalized code counts were identified for “monitoring” between the expert group (mean 0.18, SD 0.23) and the group of older adults (mean 0.08, SD 0.15; t96=2431, P=.02). Time-dependent data was most relevant across all eHealth tasks. Finally, visualization tasks and data types were assigned to eHealth tasks by both experimental groups. Conclusions We empirically developed a task-data taxonomy for health data visualizations with prospective users. This provides a general framework for theoretical concession and for the prioritization of user-centered system design and evaluation. At the same time, the functionality dimension of the taxonomy for telemedicine—chosen as the basis for the construction of present taxonomy—was confirmed.

Abstract
PURPOSE We sought to develop and validate automated performance metrics to measure surgeon performance of vesicourethral anastomosis during robotic assisted radical prostatectomy. Furthermore, we sought to methodically develop a standardized training tutorial for robotic vesicourethral anastomosis. MATERIALS AND METHODS We captured automated performance metrics for motion tracking and system events data, and synchronized surgical video during robotic assisted radical prostatectomy. Nonautomated performance metrics were manually annotated by video review. Automated and nonautomated performance metrics were compared between experts with 100 or more console cases and novices with fewer than 100 cases. Needle driving gestures were classified and compared. We then applied task deconstruction, cognitive task analysis and Delphi methodology to develop a standardized robotic vesicourethral anastomosis tutorial. RESULTS We analyzed 70 vesicourethral anastomoses with a total of 1,745 stitches. For automated performance metrics experts outperformed novices in completion time (p <0.01), EndoWrist® articulation (p <0.03), instrument movement efficiency (p <0.02) and camera manipulation (p <0.01). For nonautomated performance metrics experts had more optimal needle to needle driver positioning, fewer needle driving attempts, a more optimal needle entry angle and less tissue trauma (each p <0.01). We identified 14 common robotic needle driving gestures. Random gestures were associated with lower efficiency (p <0.01), more attempts (p <0.04) and more trauma (p <0.01). The finalized tutorial contained 66 statements and figures. Consensus among 8 expert surgeons was achieved after 2 rounds, including among 58 (88%) after round 1 and 8 (12%) after round 2. CONCLUSIONS Automated performance metrics can distinguish surgeon expertise during vesicourethral anastomosis. The expert vesicourethral anastomosis technique was associated with more efficient movement and less tissue trauma. Standardizing robotic vesicourethral anastomosis and using a methodically developed tutorial may help improve robotic surgical training.

Abstract
BACKGROUND The mini clinical evaluation exercise (mini-CEX)-a tool used to assess student-patient encounters-is increasingly being applied as a learning device to foster clinical competencies. Although the importance of eliciting self-assessment for learning is widely acknowledged, little is known about the validity of self-assessed mini-CEX scores. The aims of this study were (1) to explore the variability of medical students' self-assessed mini-CEX scores, and to compare them with the scores obtained from their clinical supervisors, and (2) to ascertain whether learners' self-assessed mini-CEX scores represent a global dimension of clinical competence or discrete clinical skills. METHODS In year 4, medical students conducted one to three mini-CEX per clerkship in gynaecology, internal medicine, paediatrics, psychiatry and surgery. Students and clinical supervisors rated the students' performance on a 10-point scale (1 = great need for improvement; 10 = little need for improvement) in the six domains history taking, physical examination, counselling, clinical judgement, organisation/efficiency and professionalism as well as in overall performance. Correlations between students' self-ratings and ratings from clinical supervisors were calculated (Pearson's correlation coefficient) based on averaged scores per domain and overall. To investigate the dimensionality of the mini-CEX domain scores, we performed factor analyses using linear mixed models that accounted for the multilevel structure of the data. RESULTS A total of 1773 mini-CEX from 164 students were analysed. Mean scores for the six domains ranged from 7.5 to 8.3 (student ratings) and from 8.8 to 9.3 (supervisor ratings). Correlations between the ratings of students and supervisors for the different domains varied between r = 0.29 and 0.51 (all p < 0.0001). Mini-CEX domain scores revealed a single-factor solution for both students' and supervisors' ratings, with high loadings of all six domains between 0.58 and 0.83 (students) and 0.58 and 0.84 (supervisors). CONCLUSIONS These findings put a question mark on the validity of mini-CEX domain scores for formative purposes, as neither the scores obtained from students nor those obtained from clinical supervisors unravelled specific strengths and weaknesses of individual students' clinical competence.

Abstract
Background: Clinical scales for upper extremity motor function may not capture improvement among higher functioning people with stroke. Objective: To describe upper extremity kinematics in people with stroke who score within the upper 10% of the Fugl-Meyer Assessment (FMA-UE) and explore the ceiling effects of the FMA-UE. Design: A cross-sectional study design was used. Participants: People with stroke were included from the Stroke Arm Longitudinal Study at University of Gothenburg together with 30 healthy controls. The first analysis included participants who achieved FMA-UE score > 60 within the first year of stroke (assessed at 3 days, 2 weeks, 4 weeks, 3 months, or 12 months post stroke). The second analysis included participants with submaximal FMA-UE (60-65 points, n = 24) or maximal FMA-UE score (66 points, n = 21) at 3 months post stroke. Measurements: The kinematic analysis of a standardized drinking task included movement time, velocity and strategy, joint angles of the elbow, and shoulder and trunk displacement. Results: The high FMA-UE stroke group showed deficits in seven of eight kinematic variables. The submaximal FMA-UE stroke group was slower, had lower tangential and angular peak velocity, and used more trunk displacement than the controls. In addition, the maximal FMA-UE stroke group showed larger trunk displacement and arm abduction during drinking and lower peak angular velocity of the elbow. Conclusions: Participants with near or fully recovered sensorimotor function after stroke still show deficits in movement kinematics; however, the FMA-UE may not be able to detect these impairments.

Abstract
OBJECTIVE To apply the critical incident technique (CIT) methodology to a series of perianesthetic cardiac arrest events at a university teaching hospital to describe the factors that contributed to cardiac arrest. STUDY DESIGN CIT qualitative analysis of a case series. ANIMALS A group of 16 dogs and cats that suffered a perioperative cardiac arrest between November 2013 and November 2016. METHODS If an arrest occurred, the event was discussed among the anesthesiologists. The discussion included a description of the case, a description of the sequence of events leading up to the arrest and a discussion of what could have been done to affect the outcome. A written description of the case and the event including animal signalment and a timeline of events was provided by the supervising anesthesiologist following discussion among the anesthesiologists. Only dogs or cats were included. After the data collection period, information from the medical record was collected. A qualitative document analysis was performed on the summaries provided about each case by the supervising anesthesiologist, the medical record and any supporting documents. Each case was then classified into one or more of the following: animal, human, equipment, drug and procedural factors for cardiac arrest. RESULTS The most common factor was animal (n=14), followed by human (n=12), procedural (n=4), drugs (n=1) and equipment (n=1). The majority (n=11) of animals had multiple factors identified. CONCLUSIONS AND CLINICAL RELEVANCE Cardiac arrests during anesthesia at a referral teaching hospital were primarily a result of animal and human factors. Arrests because of procedural, drug and equipment factors were uncommon. Most animals experienced more than one factor and two animals arrested after a change in recumbency. Future work should focus on root cause analysis and interventions designed to minimize all factors, particularly human ones.

Abstract
Background The integration of body-worn sensors with mobile devices presents a tremendous opportunity to improve just-in-time behavioral interventions by enhancing bidirectional communication between investigators and their participants. This approach can be used to deliver supportive feedback at critical moments to optimize the attainment of health behavior goals. Objective The goals of this systematic review were to summarize data on the content characteristics of feedback messaging used in diet and physical activity (PA) interventions and to develop a practical framework for designing just-in-time feedback for behavioral interventions. Methods Interventions that included just-in-time feedback on PA, sedentary behavior, or dietary intake were eligible for inclusion. Feedback content and efficacy data were synthesized descriptively. Results The review included 31 studies (15/31, 48%, targeting PA or sedentary behavior only; 13/31, 42%, targeting diet and PA; and 3/31, 10%, targeting diet only). All studies used just-in-time feedback, 30 (97%, 30/31) used personalized feedback, and 24 (78%, 24/31) used goal-oriented feedback, but only 5 (16%, 5/31) used actionable feedback. Of the 9 studies that tested the efficacy of providing feedback to promote behavior change, 4 reported significant improvements in health behavior. In 3 of these 4 studies, feedback was continuously available, goal-oriented, or actionable. Conclusions Feedback that was continuously available, personalized, and actionable relative to a known behavioral objective was prominent in intervention studies with significant behavior change outcomes. Future research should determine whether all or some of these characteristics are needed to optimize the effect of feedback in just-in-time interventions.

Abstract
The three-point shot (3S) is a fundamental basketball skill used frequently during a game, and is often a main determinant of the final result. The aim of the study was to investigate the effect of different metabolic conditions, in terms of heart rates, on 3S accuracy (3S%) in 24 male (Under 17) basketball players (age 16.3 ± 0.6 yrs). 3S performance was specifically investigated at different heart rates. All sessions consisted of 10 consecutive 3Ss from five different significant field spots just beyond the FIBA three-point line, i.e., about 7 m from the basket (two counter-clockwise “laps”) at different heart rates: rest (0HR), after warm-up (50%HRMAX [50HR]), and heart rate corresponding to 80% of its maximum value (80%HRMAX [80HR]). We found that 50HR does not significantly decrease 3S% (−15%, P = 0.255), while 80HR significantly does when compared to 0HR (−28%, P = 0.007). Given that 50HR does not decrease 3S% compared to 0HR, we believe that no preliminary warm-up is needed before entering a game in order to specifically achieve a high 3S%. Furthermore, 3S training should be performed in conditions of moderate-to-high fatigued state so that a high 3S% can be maintained during game-play.

Abstract
Process mapping has been identified as a strategy to improve surgical efficiency but has been inconsistently applied in the literature and underutilised in surgical practice. In this journal, we recently described our utilisation of these approaches when applied to breast reconstruction. We showed that in surgery as complex as autologous breast reconstruction, process mapping can improve efficiency, and may improve surgical teaching, education and audit. The intraoperative period specifically is an area that can be applied not only to breast reconstruction, but to a much broader range of surgical procedures. A systematic review was undertaken of the databases Ovid MEDLINE, Allied and Complementary Medicine Database, Embase and PsychINFO. Manual searching of the references from articles identified was also conducted. Data items relating to the review aims were extracted from articles' methods, applications, and outcomes. A descriptive analysis was carried out to synthesise the information on the current usage of process mapping in the intraoperative period. Seventeen of 1,488 studies were eligible for review, with all of non-randomised study design. Studies had overlap in components of the intraoperative period to which process mapping was applied. Common areas of improvement were identified. Outcome measures were assessed in ten studies that implemented interventions based on the improvement areas to increase surgical efficiency. As such, process mapping has been used as part of larger quality improvement methods, albeit with inconsistent nomenclature, to improve surgical efficiency. While it has been applied to a range of surgical specialties, there is a lack of application to the surgical component of the intraoperative period. Greater consistency in the reporting and description of process mapping will enable further research for evidence of its benefits.

Abstract
BACKGROUND Emergency airway management is commonly associated with life-threatening hypoxia and hypotension which may be preventable. AIMS The aim of this quality improvement study was to reduce the frequency of intubation-related hypoxia and hypotension. METHODS This prospective quality improvement study was conducted over 4 years in the Emergency Department of The Royal Children's Hospital, Melbourne, Australia. A preintervention cohort highlighted safety gaps and was used to design study interventions, including an emergency airway algorithm, standardized airway equipment, a preintubation checklist and equipment template, endtidal carbon dioxide monitoring, postintubation team debriefing, and multidisciplinary team training. Following implementation, a postintervention cohort was used to monitor the impact of study interventions on clinical process and patient outcome. Process measures were as follows: use of a preintubation checklist, verbalization of an airway plan, adequate resuscitation prior to intubation, induction agent dose titration, use of apneic oxygenation, and use of endtidal carbon dioxide to confirm endotracheal tube position. The primary outcome measure was first pass success rate without hypoxia or hypotension. Potential harms from study interventions were monitored. RESULTS Forty-six intubations were included over one calendar year in the postintervention cohort (compared to 71 in the preintervention cohort). Overall clinical uptake of the 6 processes measures was 85%. First pass success rate without hypoxia or hypotension was 78% in the postintervention cohort compared with 49% in the preintervention cohort (absolute risk reduction: 29.0%; 95% confidence interval 12.3%-45.6%, number needed to treat: 3.5). No significant harms from study interventions were identified. CONCLUSION Quality improvement initiatives targeting emergency airway management may be successfully implemented in the emergency department and are associated with a reduction in adverse intubation-related events.

Abstract
BACKGROUND The prospect of assessing cognition longitudinally and remotely is attractive to researchers, health practitioners, and pharmaceutical companies alike. However, such repeated testing regimes place a considerable burden on participants, and with cognitive tasks typically being regarded as effortful and unengaging, these studies may experience high levels of participant attrition. One potential solution is to gamify these tasks to make them more engaging: increasing participant willingness to take part and reducing attrition. However, such an approach must balance task validity with the introduction of entertaining gamelike elements. OBJECTIVE This study aims to investigate the effects of gamelike features on participant attrition using a between-subjects, longitudinal Web-based testing study. METHODS We used three variants of a common cognitive task, the Stop Signal Task (SST), with a single gamelike feature in each: one variant where points were rewarded for performing optimally; another where the task was given a graphical theme; and a third variant, which was a standard SST and served as a control condition. Participants completed four compulsory test sessions over 4 consecutive days before entering a 6-day voluntary testing period where they faced a daily decision to either drop out or continue taking part. Participants were paid for each session they completed. RESULTS A total of 482 participants signed up to take part in the study, with 265 completing the requisite four consecutive test sessions. No evidence of an effect of gamification on attrition was observed. A log-rank test showed no evidence of a difference in dropout rates between task variants (χ22=3.0, P=.22), and a one-way analysis of variance of the mean number of sessions completed per participant in each variant also showed no evidence of a difference (F2,262=1.534, P=.21, partial η2=0.012). CONCLUSIONS Our findings raise doubts about the ability of gamification to reduce attrition from longitudinal cognitive testing studies.

Abstract
Background There is limited research about the effects of video quality on the accuracy of assessments of physical function. Methods A repeated measures study design was used to assess reliability and validity of the finger-nose test (FNT) and the finger-tapping test (FTT) carried out with 50 veterans who had impairment in gross and/or fine motor coordination. Videos were scored by expert raters under eight differing conditions, including in-person, high definition video with slow motion review and standard speed videos with varying bit rates and frame rates. Results FTT inter-rater reliability was excellent with slow motion video (ICC 0.98-0.99) and good (ICC 0.59) under the normal speed conditions. Inter-rater reliability for FNT 'attempts' was excellent (ICC 0.97-0.99) for all viewing conditions; for FNT 'misses' it was good to excellent (ICC 0.89) with slow motion review but substantially worse (ICC 0.44) on the normal speed videos. FTT criterion validity (i.e. compared to slow motion review) was excellent (β = 0.94) for the in-person rater and good ( β = 0.77) on normal speed videos. Criterion validity for FNT 'attempts' was excellent under all conditions ( r ≥ 0.97) and for FNT 'misses' it was good to excellent under all conditions ( β = 0.61-0.81). Conclusions In general, the inter-rater reliability and validity of the FNT and FTT assessed via video technology is similar to standard clinical practices, but is enhanced with slow motion review and/or higher bit rate.

Abstract
AIM To describe the time allocation and temporal focus in nursing management. BACKGROUND There is limited information about the time allocation and temporal focus of nursing management activities. The role of nurse administrators is changing, resulting in challenges related to time management. METHODS Published literature in 2005-2014 related to the time allocation or temporal focus of nurse administrators' management activities was retrieved from five databases, and an integrative review was conducted. Data extraction, quality assessment and quantitative content analysis were performed for eight reviewed articles. RESULTS Daily reactive management activities and administrative routines were dominant in the nurse administrators' work, and strategic, proactive activities were scarce. Their daily work was fragmented by a variety of activities and numerous interruptions. CONCLUSION Little information exists about time allocation or temporal focus in nurse administrators' management activities. Further research on this topic is needed. The evidence was fairly modest, although the studies' results were generally similar. IMPLICATIONS FOR NURSING MANAGEMENT These results can be used to clarify the job descriptions of nurse administrators and to plan and focus their education and training. Organisations need to use evidence to standardise the job descriptions of different levels of nurse managers and directors.

Abstract
INTRODUCTION We studied the learning curve for percutaneous nephrolithotomy of urology residents according to stone complexity. METHODS The learning curve of 8 residents with no previous experience of solo percutaneous nephrolithotomy was studied. Stones were classified according to complexity using the Guy stone score. Competence was reviewed using 4 markers, namely operative time, fluoroscopic time, complication rate using the modified Clavien grading system and success rate. Analysis was done in 3-month cohorts to determine how and when competence and excellence were achieved during 1 year of training for various grades of stone. The results of resident surgeons were compared with those of experienced endourologist. RESULTS Resident surgeons achieved a plateau in mean operative time and fluoroscopic time for grade I stones after 30 to 35 cases but not for more complex stones. Similarly complications were decreased significantly only in grade I stone cases. Resident surgeons also achieved an almost excellent success rate of 87% for grade I stones only. CONCLUSIONS This study of the learning curve of residents suggests that competence and near excellence is reached after 30 to 35 cases for grade I stones. However the learning curve for complex stones (grades II to IV) is steeper and requires more experience.

Abstract
Usability testing allows human factors professionals to identify and mitigate issues with the design and use of medical technology. The test results, however, can be paradoxical and therefore be misinterpreted, limiting their usefulness. The paradoxical findings can lead to products that are not aligned with the needs and constraints of their users. We herein report on our observations of the paradox of expertise, the paradox of preference versus performance, and the paradox of choice. Each paradox explored is in the perspective of the design of medical technology, the issues that need to be considered in the interpretation of the test results, as well as suggestions on how to avoid the pitfalls in the design of medical technology. Because these paradoxes can influence product design at various stages of product development, it is important to be aware of the effects to interpret the findings properly.

Abstract
OBJECTIVE This study aims to explore the views of members of theater teams regarding the proposed introduction of a workplace-based assessment of nontechnical skills of surgeons (NOTSS) into the Intercollegiate Surgical Curriculum Programme in the United Kingdom. In addition, the previous training and familiarity of the members of the surgical theater team with the concept and assessment of NOTSS would be evaluated. DESIGN A regional survey of members of theater teams (consultant surgeons, anesthetists, scrub nurses, and trainees) was performed at 1 teaching and 2 district general hospitals in South Yorkshire. RESULTS There were 160 respondents corresponding to a response rate of 81%. The majority (77%) were not aware of the NOTSS assessment tool with only 9% of respondents reporting to have previously used the NOTSS tool and just 3% having received training in NOTSS assessment. Overall, 81% stated that assessing NOTSS was as important as assessing technical skills. Trainees attributed less importance to nontechnical skills than the other groups (p ≤ 0.016). Although opinion appears divided as to whether the presence of a consultant surgeon in theater could potentially make it difficult to assess a trainee's leadership skills and decision-making capabilities, overall 60% agree that the routine use of NOTSS assessment would enhance safety in the operating theater and 80% agree that the NOTSS tool should be introduced to assess the nontechnical skills of trainees in theater. However, a significantly lower proportion of trainees (45%) agreed on the latter compared with the other groups (p = 0.001). CONCLUSIONS Our survey demonstrates acceptability among the theater team for the introduction of the NOTSS tool into the surgical curriculum. However, lack of familiarity highlights the importance of faculty training for assessors before such an introduction.

As both mini-CEXs and OSCEs assess clinical skills, but within different contexts, this study aims at analyzing to which degree students' mini-CEX scores can be predicted by their recent OSCE scores and/or context characteristics. METHODS Medical students participated in an end of Year 3 OSCE and in 11 mini-CEXs during 5 different clerkships of Year 4. The students' mean scores of 9 clinical skills OSCE stations and mean 'overall' and 'domain' mini-CEX scores, averaged over all mini-CEXs of each student were computed. Linear regression analyses including random effects were used to predict mini-CEX scores by OSCE performance and characteristics of clinics, trainers, students and assessments. RESULTS A total of 512 trainers in 45 clinics provided 1783 mini-CEX ratings for 165 students; OSCE results were available for 144 students (87%). Most influential for the prediction of 'overall' mini-CEX scores was the trainers' clinical position with a regression coefficient of 0.55 (95%-CI: 0.26-0.84; p < .001) for residents compared to heads of department. Highly complex tasks and assessments taking place in large clinics significantly enhanced 'overall' mini-CEX scores, too. In contrast, high OSCE performance did not significantly increase 'overall' mini-CEX scores. CONCLUSION In our study, Mini-CEX scores depended rather on context characteristics than on students' clinical skills as demonstrated in an OSCE. Ways are discussed which focus on either to enhance the scores' validity or to use narrative comments only.
