Objetivo Presentar los resultados psicométricos de la escala de convivencia con artrosis (EC-Artrosis) en la población española. Diseño Estudio observacional, multicéntrico y transversal, con retest en una fracción de la muestra. Emplazamiento Centros públicos y privados de atención primaria y secundaria, así como asociaciones de pacientes con artrosis de Navarra, La Rioja, Madrid, Valencia y Málaga. Participantes La muestra estuvo compuesta por un total de 291 pacientes con diagnóstico de artrosis por su médico, en cualquier estadio de la enfermedad de atención primaria o especializada, nacionalidad española, y no hospitalizados. Intervenciones De manera adicional a la EC-Artrosis, se incluyó un cuestionario sociodemográfico y escalas para evaluar el apoyo social percibido por el paciente (DUFSS), la calidad de vida relacionada con la salud (WHOQOL-BREF) y la escala de satisfacción con la vida del paciente. Mediciones principales Se analizaron las propiedades psicométricas de la escala EC-Artrosis, tales como viabilidad y aceptabilidad, fiabilidad (consistencia interna y estabilidad), precisión y validez de constructo (convergente, interna y para grupos conocidos). Resultados El 100% de los datos fueron computados. La calidad de los datos y la aceptabilidad fueron excelentes. El alfa de Cronbach para el total de la escala fue de 0,87 y el índice de homogeneidad de 0,22. El ICC para el total de la escala fue de 0,88. En cuanto a la precisión, el valor del EEM fue de 5,18 (<½DE = 7,47). Conclusiones La EC-Artrosis ha mostrado ser un instrumento válido y fiable para evaluar la convivencia del paciente con artrosis a nivel nacional.

Background: Leisure-time physical activity (LTPA) is not the same as occupational activity. Various factors influence both forms of physical activity, including job stress and job satisfaction, but the associations found are weak, and the need for new studies in large populations is emphasized. The objective was to study the relationship between job stress and job satisfaction, and the relationship between these and occupational and leisure-time physical activity according to the National Survey of Health 2017. Methods: A population-based study of 8716 workers between 18 and 65 years of age. The variables age, sex, leisure, and occupational-time physical activity (OTPA), educational level, type of occupation, job stress level, and job satisfaction were collected. A simple and multiple correspondence analysis was performed between the variables that reached statistical significance. Results: 4621 cases (53.02%) correspond to men with a mean age of 44.83 years (SD 10.22) and 4095 cases to women with a mean age of 44.55 years (SD 10.23). Women had higher percentages of higher education (p < 0.001), intermediate to high occupations and unskilled (p < 0.001), job stress (p < 0.001), covered the most extreme levels of satisfaction (p = 0.003), and do less LTPA (p < 0.001) and OTPA (p < 0.001). Also, in women a relationship was found between job stress and LTPA (p = 0.024), as well as between satisfaction and both forms of physical activity (OTPA p = 0.013 and LTPA p < 0.001). In men, significance was only reached in the relationship between job stress and OTPA (p <0.001). Conclusions. The higher the job stress, the less the job satisfaction, but the relationship is reversed in the intermediate categories. For both sexes, job stress is related to a sedentary lifestyle and higher employment and education levels. Higher levels of satisfaction correspond to higher levels of occupancy. The relationship between job satisfaction and educational level is direct in women but inverse in men. In women, there is a relationship between sedentary occupations and job satisfaction. In addition, intense physical activity at work is related to higher levels of job stress, lower satisfaction levels, and less physical activity in leisure-time.

Idiopathic toe-walkers (ITWs) pedobarographic analysis has not been described yet nor its possible relationship with orthopedical and developmental characteristics. The objective of this research is to develop a dynamic pedobarographic classification of ITWs to propose a specific therapeutical approach. Through an observational study, 56 ITWs aged 3-6 years were classified by their initial foot contact; differences between idiopatic toe-walking (ITW) types and with respect to 40 control children were calculated by means of ANOVA and Student t-tests. The results show that the three ITW types displayed different step models for pressure and impulse distribution and also for temporal development (p < .05). They also showed different orthopedic and developmental characteristics (p < .05). As a whole, they demonstrated different severity levels, which suggest different therapeutical indications. This study confirms the convenience of a specific orthopedic, developmental, and gait assessment in ITW to clarify therapeutical indication.
