Comprehensive Physical Work Capacity Evaluations for Korean Farmers Assessed in Healthy Volunteers.

OBJECTIVE: To establish the lower limits of normative values of the physical work capacity for Korean farmers in healthy working individual. METHODS: We developed a comprehensive set of physical work capacity evaluation items that encompass common farming tasks. These items include measurements of trunk flexion/extension angles, strength (hand grip, trunk flexion/extension, leg/back lifting, and pushing/pulling), and positional tolerances. We calculated the normative values for the items and defined the normal range in 124 healthy volunteers aged 20-79 years. We calculated the intraclass correlation coefficient (ICC) to validate the test-retest reliability of the measurements protocol. RESULTS: The normal values for each measurement item were as follows: trunk flexion and extension angle (65.3°±11.6° and 29.6°±6.6°), dominant hand grip strength (32.2±10.5 kgf), trunk flexion and extension strength (288.4±119.0 N and 297.3±129.9 N), leg and back lifting strength (452.9±233.5 N and 349.2±166.7 N), pushing and pulling strength (214.7±75.1 N and 221.7±63.3 N), and positional tolerance time (squat: 76.8±9.0 seconds, front: 73.8±7.7 seconds, twist: 82.2±8.8 seconds, upward: 71.9±11.3 seconds). Regarding test-retest reliability, all strength measurements demonstrated excellent absolute agreement (ICC, 0.91-0.96). However, positional tolerance showed poor-to-moderate absolute agreement (ICC, 0.37-0.58). CONCLUSION: We conducted measurements of muscle strength and positional tolerance in healthy participants of various ages, focusing on tasks commonly performed by Korean farmers. The outcomes hold significant value as they offer a pertinent instrument for assessing the appropriateness of workers, thereby carrying implications for rehabilitation objectives, legal evaluations, and work capacity assessments within the agricultural domain.

Work ability of school servants and the mediating effects between personal characteristics, work conditions, and sickness absence1.

BACKGROUND: School servants are professionals involved with cleaning and feeding activities in schools. Exposed to conditions of physical and psychosocial overload at work, they may face situations of morbidity and functional restrictions. OBJECTIVE: To evaluate personal and work characteristics and work ability index (WAI) of school servants in Brazil and test the mediating effect of WAI in the duration of sickness absence. METHODS: 163 Brazilian school servants participated in this cross-sectional study, that including the self-completion of a sociodemographic questionnaire, information about the Work Environment, the Protocol of Psychosocial Risks at Work's Evaluation, and the Work Ability Index. Also was collected, in a secondary health database, information about sickness absence. A linear regression model was constructed to identify the predictors of the duration of absence, followed by the analysis of mediation with the Path Analysis method. RESULTS: The study found that the WAI partially mediates the relation of the personal characteristics and the work conditions with the duration of absence of the school servants. The predictors included the organizational aspects of work, mental exhaustion, physical damage, health self-evaluation, availability of personal protective equipment, and the need to assume inadequate postures at work. These predictors explained 33% of the duration of absence and 53% of the WAI of these workers. CONCLUSION: This study indicated that inadequate working conditions and low WAI impact in the sickness absence, increasing by 33% the length of time off work of school servants.

Musculoskeletal complaints, physical work demands, and functional capacity in individuals with a brachial plexus injury: An exploratory study.

BACKGROUND: Musculoskeletal complaints (MSCs) may be more common in individuals with brachial plexus injury (BPI), whose physical work demands exceed their functional capacity (FC). OBJECTIVES: (a) To assess the concurrent validity of five methods for measuring upper extremity work demands and the Dictionary of Occupational Titles (DOT). (b) To explore the relations between MSCs, physical work demands, and FC in individuals with BPI. METHODS: This study had a descriptive correlational design. Physical work demands of 16 individuals with BPI (12 males, 6 one-handed workers) were assessed during work using five assessment methods and the DOT. Spearman correlation coefficients between work demand methods were determined. FC was assessed using the functional capacity evaluation one-handed (FCE-OH). A questionnaire was used to examine MSCs. The relationship between MSCs, physical work demands and FC was analyzed visually, using Spearman correlation coefficients, and by comparing FCE-OH results to FCE reference values. RESULTS: Spearman correlation coefficients for the DOT and four out of five assessment methods for determining work demands on upper extremities were significant and moderate (four combinations: r = 0.65-0.79) to strong (five combinations: r = 0.81-0.94). Correlations of the fifth method with the other methods were weak to fair. No significant relationships were found between MSCs, physical work demands and FCE-OH results. CONCLUSION: The relationships between MSCs, physical work demands, and FC are evidently complex and require further investigation. In this small sample the concurrent validity of the DOT and four methods for determining work demands on upper extremities was moderate to good.

Comprometimento da Capacidade para o Trabalho e efeitos neuropsicológicos entre trabalhadores com Covid-19 prévia / Impairment of Work Ability and neuropsychological effects among workers who have had COVID-19

RESUMO A Covid-19 é uma doença multissistêmica e consequências funcionais e tardias estão em estudo. Sequelas psicológicas e neurocognitivas podem comprometer a Capacidade para o Trabalho (CT) dos trabalhadores. Objetivou-se investigar a CT de pessoas previamente infectadas pelo Sars-CoV-2, correlacionando-a com avaliação da sonolência, ansiedade, depressão e fadiga. Estudo transversal, com trabalhadores diagnosticados com Covid-19 e em acompanhamento no Serviço de Neurologia da Universidade Estadual de Campinas (Unicamp). Aplicou-se o instrumento Índice de Capacidade para o Trabalho (ICT), um formulário com dados sociodemográficos e ocupacionais, bem como escalas de sonolência, ansiedade, depressão e fadiga. Dos 119 trabalhadores que participaram do estudo, mais da metade apresentaram comprometimento da CT (52,9%). Distúrbio emocional foi o agravo relatado mais frequente (31,9%). A regressão logística múltipla mostrou que a interação entre ansiedade e sonolência esteve associada ao comprometimento da CT (OR=4,50 com p=0,002). Ansiedade e sonolência foram alterações tardias da Covid-19 e associadas ao comprometimento da CT dos trabalhadores avaliados. Este estudo demonstra a necessidade de que todos os trabalhadores com teste positivo por Covid-19 tenham sua CT avaliada por ocasião do retorno ao trabalho. Ações de promoção à saúde, reabilitação funcional e adaptação do trabalho de acordo com as sequelas apresentadas pelos trabalhadores.

ABSTRACT COVID-19 is a multisystemic disease, with functional and late consequences still under study. Psychological and neurocognitive sequelae impact workers' quality of life and may compromise the Work Ability (WA). The objective was to investigate the WA of people infected with SARS-CoV-2, correlating it with the assessment of sleepiness, anxiety, depression and fatigue. Cross-sectional study, involving workers diagnosed with COVID-19 under follow-up at the Department of Neurology of Universidade Estadual de Campinas (UNICAMP). Application of the Work Ability Index (WAI) analyzed with sociodemographic and occupational variables, as well the sleepiness, anxiety, depression and fatigue scales. Multiple logistic regression analysis was performed. 119 workers participated in the study and, among them, more than half had WA impairment (52.9%). Emotional disorders were the most frequent reported problem (31.9%). Multiple logistic regression showed that the interaction between anxiety and sleepiness was associated with WA impairment (OR=4.50, p=0.002). Anxiety and sleepiness were associated with previous COVID-19 and they were associated with WA impairment among workers. This study shows the WA evaluation should be provided for all workers with a previous history of COVID-19, when they return to work. This assessment can guide health promotion actions, functional rehabilitation and work adaptation to the sequelae presented by workers, singularly.

Bridging the gap: Hospital to workplace.

BACKGROUND: Work-oriented neurorehabilitation to return to competitive employment after a serious neurologic illness or injury is an interdisciplinary process that begins as soon as pathology has stabilized. OBJECTIVE: This bimonthly column provides narratives of anonymized clients in situations that challenge their return-to-work. Each case study is designed for postgraduate education about tools and methods that are appropriate to consider in similar situations. METHODS: Through case studies of adults attempting to return to safe and dependable competitive employment, real-world issues are explored that occur at the interface between the client and their employer. RESULTS: The current case describes Structured Task Self Appraisal (STSA), a forensic rehabilitation method to collect self-report baseline information concerning the client's job-relevant functional limitations. STSA guides return-to-work rehabilitation services. CONCLUSION: Information concerning the core tasks and important abilities of the client's target occupation that are immediately available in O*NET can be analyzed in a structured manner to provide the workplace context for rehabilitation.

[Analysis of the profile of employees declared unfit for the job : How do societal or extra-professional factors contribute, and what are the consequences for employment?] / Analyse du profil des salariés déclarés inaptes au poste de travail : quelle place pour les facteurs sociétaux ou extra-professionnels et quelles conséquences sur l'emploi ?

INTRODUCTION: Professional career can be modified by health problems. Professional impairment, certified by an occupational health physician, can be followed by a redeployment or occupational disintegration. OBJECTIVES: To describe the profiles of workers declared unfit for their workplace and the profiles of those who have no remaining work capacity (RWC). METHODS: The workers followed by an inter-enterprise occupational health service composed of 20 occupational physicians. The characteristics of workers declared unfit for work were extracted from the medical files: age, gender, activity sector (Naf), socioprofessional category (PCS), pathology leading to professional impairment (CIM10), status of obligation to employ disabled workers (BOETH). Factors associated with unfitness to work due to no remaining work capacity (RWC) were identified by logistic regression models. RESULTS: In 2019, 82678 workers in France were followed by the SPSTI and 554 (0.67%), of whom 162 had no RWC, were declared unfit to work by an occupational health physician. Professional impairment rates were highest for women and workers > 55 years old. Psychological (29%) and rheumatic (50%) pathologies were the most frequent causes of professional impairment. BOETH status was identified among 63%. Age > 45 and psychological pathology were significantly associated with absent RWC, whereas gender, activity sector and PCS were not. DISCUSSION: No comprehensive public administration records of professional impairment exist in France. While past studies have described the profiles of workers who were unfit for their workplace, none have characterized those without RWC, who are high risk of precarity. CONCLUSIONS: Psychological pathologies generate the most professional impairment in persons without RWC. Prevention of these pathologies is essential. While rheumatic disease is the first cause of professional impairment, the proportion of workers with these diseases who have no remaining work capacity is relatively low; this may be due to the efforts made to facilitate their return to work.

Functional capacity of individuals with brachial plexus injury.

BACKGROUND: To enable (pain free) functioning, individuals with brachial plexus injury (BPI) may require a higher functional capacity compared to two-handed individuals, because the load on unaffected structures is greater. OBJECTIVE: This study compared the functional capacity of individuals with BPI and healthy controls and explored differences in the functional capacity of BPI-affected individuals with respect to: those with and without hand function; affected and unaffected sides; with and without musculoskeletal complaints (MSCs). METHODS: Six functional capacity tests adjusted for one-handed function were performed by 23 BPI-affected individuals and 20 healthy controls. Hand function was assessed through physical examination and the Dutch Musculoskeletal Questionnaire was used to assess MSCs. RESULTS: Individuals with BPI scored lower for the two-handed tests, compared with the controls (p≤0.01, effect size (r) ≤-0.41 for both tests). However, both groups performed similar in the one-handed tests. On average individuals with BPI met the physical demands to perform sedentary to light physical work. Among BPI-affected individuals, two-handed overhead lifting capacity was higher in those with hand function than in those without hand function (p = 0.02; r = 0.33). Functional capacity tended to be lower for the unaffected side than for the affected side (4 tests; p≤0.05, r≤-0.36). Test results of BPI-affected Individuals with and without MSCs were similar. CONCLUSION: Individuals with BPI demonstrated lower two-handed functional capacity than healthy controls. Effect sizes were medium. Capacity of their unaffected side was similar to the dominant side of controls. No association was found between MSCs and functional capacity.

Mapping information regarding the work-related disability of depression and long-term musculoskeletal pain to the International Classification of Functioning, Disability and Health and ICF Core Sets.

Introduction: The International Classification of Functioning, Disability and Health is the WHO coding scheme for functioning-related data. Clear and unambiguous information regarding patients' work-related disabilities is important not only for the assessment of entitlement to paid sickness benefits but also for planning rehabilitation and return to work. The objective was to validate the content of ICF and ICF Core Sets for information on work-related disability in sick leave due to depression and long-term musculoskeletal pain. Specific aims: To describe to what extent (1) such data could be linked to ICF and (2) the result of the ICF linking in terms of ICF categories was represented in relevant ICF Core Sets. Methods: An ICF-linking study following the ICF-linking rules. A random sample of sick leave certificates issued in primary care for either depression (n = 25) or long-term musculoskeletal pain (n = 34) was collected from a community with 55,000 inhabitants in Stockholm County, Sweden. Results: The results of the ICF linking consisted of codings for (1) ICF categories and (2) other health information not possible to link to ICF. The ICF categories were compared to ICF Core Sets for coverage. The majority of the meaning units, 83% for depression and 75% for long-term musculoskeletal pain, were linked to ICF categories. The Comprehensive ICF Core Set for depression covered 14/16 (88%) of the ICF categories derived from the ICF linking. The corresponding figures were lower for both the Brief ICF Core Set for depression 7/16 (44%) and ICF Core Set for disability evaluation in social security 12/20 (60%). Conclusion: The results indicates that ICF is a feasible code scheme for categorising information on work-related disability in sick leave certificates for depression and long-term musculoskeletal pain. As expected, the Comprehensive ICF Core Set for depression covered the ICF categories derived from the certificates for depression to a high degree. However, the results indicate that (1) sleep- and memory functions should be added to the Brief ICF Core Set for depression, and (2) energy-, attention- and sleep functions should be added to the ICF Core Set for disability evaluation in social security when used in this context.

Haemodialysis nurses' occupational health and work-related musculoskeletal hand pain after work: A cluster analysis.

AIM: To identify clusters based on haemodialysis nurses' self-rated work ability, work engagement and self-reported work hours and to compare the identified clusters regarding hand pain after work. DESIGN: Cross-sectional survey. METHODS: Data based on the Work Ability Index, Utrecht Work Engagement Scale and hand pain severity after work were collected through a web-based survey among 503 haemodialysis nurses working in Sweden and Denmark. A two-step cluster analysis was used to identify homogenous groups of cases within the dataset, followed by comparative analyses of the clusters. RESULTS: Four distinct clusters were identified, illustrating differing profiles of haemodialysis nurses' work ability, work engagement and working hours. Nurses who worked part-time and reported moderate work ability and average work engagement had significantly higher ratings of hand pain after work. CONCLUSIONS: Haemodialysis nurses are a heterogeneous group as regards work ability, work engagement and self-reported work hours. The four distinct clusters of nurses indicate a need for customized interventions for retaining each subgroup at work.

Work situation, work ability and expectation of returning to work in patients with systemic autoimmune myopathies.

OBJECTIVES: To document the work situation, the work ability and the expectation of returning to work among adult patients with systemic autoimmune myopathies (SAMs), and to identify the factors associated with each of these outcomes. METHODS: Cross-sectional study. The work situation (performing paid work vs out of work) was ascertained via a structured questionnaire. For those who were working, we applied the Work Ability Index (WAI; scale 7-49); and for those who were out of work, we applied the Return-to-Work Self-Efficacy questionnaire (RTW-SE; scale 11-66). RESULTS: Of the 75 patients with SAMs included, 33 (44%) were doing paid work and 42 (56%) were out of work. The work situation was independently associated with physical function, assessed by the Health Assessment Questionnaire-Disability Index (HAQ-DI). A 1-point increase in the HAQ-DI (scale 0-3) decreased the chance of doing paid work by 66% (95% CI: 0.16, 0.74; P = 0.007). Patients performing paid work had a mean WAI of 33.5 (6.9). The following variables were associated with a decrease in the WAI score in the regression model: female sex (-5.04), diabetes (-5.94), fibromyalgia (-6.40), fatigue (-4.51) and severe anxiety (-4.59). Among those out of work, the mean RTW-SE was 42.8 (12.4). Cutaneous manifestations and >12 years of education were associated with an average increase of 10.57 and 10.9 points, respectively, in the RTW-SE. A 1-point increase in the HAQ-DI decreased the RTW-SE by 4.69 points. CONCLUSION: Our findings highlight the poor work participation in a well-characterized sample of working-age patients with SAMs. Strategies to improve work-related outcomes in these patients are urgently needed.

Factors related to work ability among nursing professionals from urgent and emergency care units: A cross-sectional study.

BACKGROUND: Nursing professionals are on the front line of health systems in Brazil as well as worldwide. Studies on the work ability of nursing professionals are especially relevant as care demands increase and health care workforce shortages are expected. As the population of Brazil ages, the need for nursing care will increase. OBJECTIVE: To identify levels and predictors of work ability among Brazilian nursing professionals. METHODS: A cross-sectional study with 267 nursing professionals (72 nurses and 195 nursing technicians and nursing auxiliary) from public emergency and urgent care units was conducted. Measures included the following: Work Ability Index; Questionnaire of Socio-demographics, Lifestyle and Work and Health Aspects; and Violence at Work questionnaire. Generalized linear regression and Poisson models were used for data analysis. RESULTS: The mean work ability was 40.4 (range: 22 to 49). Almost 79.6% (n = 211) of participants reported good or excellent work ability, and 20.4% (n = 54) reported moderate or poor work ability. Better perceptions of health and job satisfaction, absence of health issues (past 15 days), lower stress levels, and having a partner were associated with better work ability. Victims of workplace violence were less likely to have good or excellent work ability than non-victims (prevalence ratio = 0.80; 95% CI 0.72 to 0.90). Professionals with cumulative experiences of workplace violence were less likely to report better work ability. CONCLUSIONS: The prevalence of good or excellent work ability was 79.6%. Our findings indicate that the following factors are predictors of work ability: self-reported perception of health, health issues in the last 15 days, workplace violence, job satisfaction, stress, and marital status.

Perceptions of medical advisers on ICF core-sets' use for evaluating work incapacity related to back pain in French-speaking Belgium.

BACKGROUND: There is willingness in Europe to implement the use of a biopsychosocial model such as the International Classification of Functioning, Disability and Health (ICF) for assessing work incapacity. OBJECTIVE: A preliminary study was conducted to investigate the perceptions of medical advisers on the value of structuring clients' biopsychosocial information in an ICF-based report. METHOD: A sample (n = 101) received a perception questionnaire after watching two comparative videos based on a clinical case. Questions relating to work incapacity were also asked. The data was analysed using quantitative methods. Comments were also collected. RESULTS: Before knowing the ICF-based report, 61.96% of the respondents believed a return to work seems possible by providing adapted work or a different job. There is an increase of 8.69 pp (p-value: 0.077) after reading the report. Opening up the initial sample to more insurance physicians (n = 119), the difference is more significant (p-value: 0.012). Also, 71.9% of respondents believe they have a better view of the client's biopsychosocial situation after reading the report. Respondents recognise the clinical and diagnostic relevance of ICF but say it cannot be used at the moment for various reasons, such as the time required or the need for a multidisciplinary team and effective coordination. Older respondents are less enthusiastic about the appropriateness of using ICF. CONCLUSION: The respondents identify an added value in having a biopsychosocial based-report. After learning about the report, more physicians see opportunities for professional re-integration than before. The medical advisers and their team must be strengthened and receive a clear role in order to empower them.

Estimation of Functional Reserve in Patients with Hospital-Associated Deconditioning.

BACKGROUND: This study aimed to analyze the applicability of sit-to-stand (STS) muscle power tests for evaluating functional reserve in patients with hospital-associated deconditioning (HAD). METHODS: This study is a single group preliminary observational study. STS tests were performed in the early stages of comprehensive rehabilitation treatment, and the interval changes in the clinical indicators were assessed after four weeks of clinical observation. A STS capacity ratio was estimated by the time duration of five STS repetitions (5r-STS) and the maximum number of STS repetitions over 30 s (30s-STS); the activities were measured using a three-dimension motion capture system and force plate. RESULTS: After 4 weeks of comprehensive rehabilitation, the 10 m gait speed (p = 0.004), hand grip power (p = 0.022), hip extensor power (p = 0.002), Berg balance scale (p < 0.001), and modified Barthel index (MBI) (p = 0.001), respectively, were significantly improved. The force plate-derived (FPD) 30s-STS power and the number of repeats in the FPD 30s-STS showed a positive correlation with improvements in the hand grip power (Spearman's Rho = 0.477, p = 0.045), hip extensor power (Spearman's Rho = 0.482, p = 0.043), and MAI (Spearman's Rho = 0.481, p = 0.043), respectively. The STS capacity ratio was correlated with higher improvements in the 10 m gait speed (Spearman's Rho = 0.503, p = 0.034), hip extensor power (Spearman's Rho = 0.494, p = 0.037), and MBI (Spearman's Rho = 0.595, p = 0.009). Despite individual variability in the differences between the FPD and estimated STS power, the results for the correlation between the STS capacity ratio and clinical outcomes were consistent. CONCLUSIONS: The STS capacity ratio showed a positive correlation with the clinical outcomes, including gait speed, and may reflect a part of the functional reserve excluding the individual variability of performance.

Evaluation of measurement properties of the German Work Role Functioning Questionnaire.

OBJECTIVE: We assessed the measurement properties of the German Work Role Functioning Questionnaire (WRFQ) after its cross-cultural adaptation of the Dutch version. The WRFQ is a generic role-specific instrument that measures how a particular health status influences the ability to meet work demands. METHODS: We performed an observational study among German employees assessing the following measurement properties: 1) structural, 2) convergent and 3) discriminant validity, 4) floor and ceiling effects, 5) internal consistency, 6) reproducibility and 7) responsiveness. Participants were recruited from an online access panel sample aged 18 to 64 years having worked more than 12 hours in the last 4 weeks prior to study enrollment (n(T0) = 653, n(T1) = 66, n(T2) = 95). RESULTS: Measurement properties proved to be good except for structural validity and responsiveness. An exploratory factor analysis showed limited replicability of three of the four original subscales. CONCLUSION: With the WRFQ German version, the extent can be measured, to which employees with a certain health level experience problems can meet their work demands. This widely used health-related work outcome measurement tool, that helps to identify employees with decreasing work functioning, is now also available in German. This gives researchers and practitioners the opportunity to address work functioning in practice, e.g. in intervention studies in occupational health or rehabilitation. Further research to examine valid subscales is needed.

Factors associated with work ability and intention to leave nursing profession: a nested case-control study.

This study aims to identify factors associated with impaired work ability and intention to leave the nursing profession. This is a case-control nested within a cross-sectional study. Samples were randomly selected for work ability (475 controls and 158 cases) and intention to leave profession (454 controls and 151 cases). Data on demographic, lifestyle, occupational features, work environment, work ability and intention to leave profession were collected. Multiple logistic regression analysis was performed. Factors associated with work ability impairment were: risk for moderate (OR=1.28) and high (OR=2.26) job strain, effort-reward imbalance (OR=2.82), high overcommitment (OR=1.77), situations that may contribute to musculoskeletal pain/injury with moderate (OR=1.82) or high (OR=2.58) exposures, degree level (OR=2.13) or elementary/high school level (OR=1.67), and low physical activity (OR=1.74). Age of 31-40 years (OR=0.26) and ≥41 years (OR=0.27) were protective factors. Factors associated with intention to leave profession were: high risk for job strain (OR=1.81), effort-reward imbalance (OR=3.25), situations that may contribute to musculoskeletal pain/injury with high exposure (OR=1.54), and insomnia symptoms (OR=2.72). Age >40 years was a protective factor (OR=0.50). Individual characteristics and occupational conditions were associated with work ability impairment and intention to leave profession. Measures to improve working conditions and individual resources were recommended.

Work ability and associated factors in people living with human T-cell leukemia virus type 1

ABSTRACT Background: Infection with the human T-lymphotropic virus type 1 (HTLV-1) affects an estimated 10-15 million people worldwide. However, knowledge of the impact of HTLV-1 infection on work ability is lacking. This study aimed to measure the frequency and identify factors associated with poor work ability in patients living with HTLV-1. Methods: This cross-sectional study included 207 individuals infected with HTLV-1 who attended the University Hospital in Salvador, Bahia, Brazil. HTLV-1 antibodies were detected in the participants' blood by enzyme-linked immunosorbent assay (ELISA) and confirmed by western blotting. Participants answered a questionnaire on sociodemographic data, personal habits, clinical data, health-related quality of life, and work ability, evaluated using the work ability index questionnaire. A Poisson regression model with a robust variance estimate was used to identify the factors associated with the prevalence of poor work ability. Results: Patients mean age was 55.2, ranging from 19 to 84 years, 73.0% were females, 100% had monthly family income less than US$ 394, and 33.8% presented HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP). No individual was classified as having excellent work ability. Poor work ability prevalence was strongly associated (prevalence ratio; 95% confidence interval [CI]) with sedentarism (1.30; 1.03-1.65), neurological symptoms (1.25; 1.02-1.52), and low physical (0.95; 0.94-0.96) and mental (0.98; 0.97-0.99) component summaries of health-related quality of life. Conclusions: Poor work ability among people living with HTLV-1 is associated with sedentarism, neurologic symptoms, and low health-related quality of life.

Capacidade para o trabalho e intenção de saída da profissão na enfermagem de São Paulo / Work ability and intending to leave the nursing profession in São Paulo / Capacidad de trabajo e intención de dejar la profesión en enfermería en São Paulo

identificar o perfil de capacidade para o trabalho e intenção de saída da profissão na enfermagem. Método: um estudo transversal junto a 3051 profissionais do estado de São Paulo, com coleta de dados realizada por meio da internet avaliando características pessoais, ocupacionais, condições de trabalho, capacidade para o trabalho e ISP. Foi feita análise descritiva dos dados e associações verificadas por meio do teste qui-quadrado. Resultados: entre os profissionais, 55,4% tinham capacidade para o trabalho comprometida e 33,5% tinham intenção de saída presente. A intenção de saída aumentava na medida em que aumentava o comprometimento da capacidade para o trabalho (p<0,001). Foram identificadas condições físicas e psicossociais inadequadas de trabalho. Conclusão: o comprometimento da capacidade para o trabalho e a presença de intenção de saída da profissão a foram frequentes entre os profissionais de enfermagem, sendo que condições laborais inadequadas estão presentes no trabalho desse contingente profissional.

to identify the profile of work ability and intention to leave the nursing profession. Method: in this cross-sectional study of 3051 nurses in São Paulo state, data on personal and occupational characteristics, working conditions, work ability and intention to leave were collected through the Internet. Descriptive analysis was performed and associations were identified using the chi-square test. Results: 55.4% of the nurses' work ability was impaired and 33.5% intended to leave. Intention to leave increased as impairment of fitness for work increased (p < 0.001). Inadequate physical and psychosocial work conditions were identified. Conclusion: impaired work ability and the intention to leave the profession were frequent among professional nurses, and their work was found to suffer from inadequate labour conditions.

Towards the Use of 2D Video-Based Markerless Motion Capture to Measure and Parameterize Movement During Functional Capacity Evaluation.

Purpose The objective of this study was to determine the agreement of kinematic parameters calculated from motion data collected via a 2D video-based pose-estimation (markerless motion capture) approach and a laboratory-based 3D motion capture approach during a floor-to-waist height functional lifting test. Method Twenty healthy participants each performed three floor-to-waist height lifts. Participants' lifts were captured simultaneously using 2D video (camcorder) in the sagittal plane and 3D motion capture (Vicon, Oxford, UK). The three lifts were representative of a perceived light, medium, and heavy load. Post-collection, video data were processed through a pose-estimation software (i.e., markerless motion capture). Motion data from 3D motion capture and video-based markerless motion capture were each used to calculate objective measures of interest relevant to a functional capacity evaluation (i.e., posture, balance, distance of the load from the body, and coordination). Bland-Altman analyses were used to calculate agreement between the two methods. Results Bland-Altman analysis revealed that mean differences ranged from 1.9° to 22.1° for posture and coordination-based metrics calculated using markerless and 3D motion capture, respectively. Limits of agreement for most posture and coordination measures were approximately + 20°. Conclusions 2D video-based pose estimation offers a strategy to objectively measure movement and subsequently calculated metrics of interest within an FCE context and setting, but at present the agreement between metrics calculated using 2D video-based methods and 3D motion capture is insufficient. Therefore, continued effort is required to improve the accuracy of 2D-video based pose estimation prior to inclusion into functional testing paradigms.
