Reliability of the spanish version of Questionnaire of Physical Activity PAQ-C

Objetivo. El objetivo de esta investigación ha sido valorar en niños españoles la fiabilidad del cuestionario de actividad física en niños mayores (PAQ-C). Método. Se utilizó como referencia la validación de la versión traducida al castellano del cuestionario de actividad física para adolescentes PAQ-A. En una muestra de 72 niños entre 8 y 14 años, se evaluó la fiabilidad test-retest del cuestionario PAQ-C en 3 mediciones, antes de la clase de educación física (M1), 2 horas después (M2) y al cabo de una semana (M3). La fiabilidad se calculó mediante el coeficiente de correlación intraclase (ICC) y la consistencia interna mediante el Coeficiente α de Cronbach. Resultados: Los valores obtenidos en la puntuación total del cuestionario reflejan un ICC superior a 0.73 en todas las comparaciones, con un intervalo de confianza al 95% que sigue indicando una fiabilidad buena o excelente. La consistencia interna mostró un coeficiente de α = 0,83Background: The aim of this study was to assess the reliability of the PAQ-C questionnaire in spanish older children (PAQ-C). Methods: A proof translation in Spanish of the physical activity questionnaire for teenager PAQ-A, was used as reference. Reliability of the test-retest questionnaire PAQ-C, was evaluated on 72 children aged between 8 and 14 years. Measurements were taken at three different stages: before the physical education class (M1), 2 hours after the lecture (M2) and one week later (M3). Reliability was calculated using the intraclass correlation coefficient (ICC) while the inner consistency by Cronbach's αcoefficient. Results: The results obtained in the overall score of the questionnaire reflect an intraclass coefficient (ICC) higher than 0,73 in every possible comparison giving a confidence interval of 95% which still indicates a good or very good reliability. The inner consistency showed a coefficient of α = 0,8

Validity and reliability of the satel 40 HZ stabilometric force platform for measuring quiet stance and dynamic standing balance in healthy subjects

Background: A force platform must have validity and reliability for optimal use. The objective of this study was to analyze the validity and the reliability of the Satel 40 Hz stabilometric force platform. Methods: A study of instrumental validity and reliability, involving a cross-sectional correlational and comparative analysis was performed. To determine the validity, four certified weights located on three axes were used and the ability of the stabilometric force platform to detect changes in the position of the different axes was observed. A test–retest was performed to analyze the reliability. Forty-two symptom-free volunteers participated in the study. Assessments were taken in a standing static position and in a dynamic position, with the eyes open and closed. Three measurements were taken and the intra-class correlation coefficient (ICC) was calculated. Results: The validity increased as the weight increased for all the variables measured in the stabilometric parameters (p < 0.05). The reliability was shown to be good to excellent for the two visual conditions. The positional variables obtained a higher ICC. The variable with the best ICC was the Y mean in OE (ICC 0.874 and a p < 0.001). All the values showed an increase in a dynamic situation. Conclusion: The findings support the reliability and validity of the Satel 40 Hz stabilometric force platform. The platform could be recommended to evaluate static and dynamic standing balance in healthy adult individuals. Guidelines for treatment and the level of quality of stabilometry could be obtained from its use

Barriers against incorporating evidencebased practice in physical therapy in Colombia: current state and factors associated

Background: Evidence-based practice (EBP) has been widely implemented in differing areas of physiotherapy. Nevertheless, few studies have investigated EBP-related barriers amongst Latin-American physical therapists working in primary care. The primary objective of this study was to describe the current state concerning perceived barriers engagement in EBP among physical therapy in Colombia. A secondary objective was to identify factors associated with barriers to implementation EBP. Methods: A cross-sectional online survey was conducted. The study involved physical therapists working in public and private hospital who were contacted through professional networks (Email, Facebook®, ResearchGate® and Linked-In®) and invited to participate. Multiple logistic regression (MLR) and multiple correspondence analysis (MCA) were used for examining factors associated with perceived barriers to including EBP in their work. Results: The final sample size was 1064 (77.2 % female). Forty-one percent of the respondents indicated that a “lack of research skills” was the most important barrier to evidence being used in practice. MLR analysis suggested that several variables were associated with perceived barriers to including EBP: i.e. hours of work per week, current main role in therapy center and undergraduate degree. The MCA model established two groups of similarities regarding the different barriers; the "lack of understanding of statistical analysis", "insufficient time" and "understanding of the English in which articles are written" barriers were weighted more heavily regarding in the first group (the second factor on MCA) and the rest barriers on the second group (first factor on the MCA). Conclusions: Although most physiotherapists had a positive opinion regarding EBP, they considered that they needed to improve their knowledge, skills and attitudes towards EBP. Initiatives to advance EBP in Colombia with no academic or research tradition should primarily target practitioner-level factors

Treadmill interventions with partial body weight support in children under six years of age at risk of neuromotor delay:a report of a Cochrane systematic review and meta-analysis

Delayed motor development may occur in children with Down syndrome, cerebral palsy or children born preterm, which in turn may limit the child's opportunities to explore the environment. Neurophysiologic and early intervention literature suggests that task-specific training facilitates motor development. Treadmill intervention is a good example of locomotor task-specific training. Aim. The aim of this paper was to assess the effectiveness of treadmill intervention on locomotor motor development in pre-ambulatory infants and children under six years of age who are at risk for neuromotor delay. Design. A Cochrane systematic review with meta-analysis. Methods. We employed a comprehensive search strategy. We included randomised, quasi-randomised and controlled clinical trials that evaluated the effect of treadmill intervention in children up to six years of age with delays in gait development or the attainment of independent walking or who were at risk of neuromotor delay. We searched CENTRAL, MEDLINE, EMBASE, PsycINFO, CINAHL, Science Citation Index, PEDro, CPCI-S and LILACS; and also ICTRP, ClinicalTrials.gov, mRCT and Center Watch. Four authors independently extracted the data using standardized forms. Results. We included five studies, which reported on treadmill intervention in 139 children. Of the 139 children, 73 were allocated to treadmill intervention groups. The studies varied in the type of population studied, the type of comparison, the time of evaluation and the parameters assessed. Due to the diversity of the studies, we were only able to use data from three studies in meta-analyses and these were limited to two outcomes: age of onset of independent walking and gross motor function. Evidence suggested that treadmill intervention could lead to earlier onset of independent walking when compared to no treadmill intervention (effect estimate -1.47; 95% CI: -2.97, 0.03), though these trials studied two different populations: Down syndrome and children at risk of neuromotor disabilities. Children with Down syndrome seemed to benefit while it was not clear if this was the case for children at high risk of neuromotor disabilities. Two other studies, both in children with Down syndrome, compared different types of treadmill intervention (high versus low intensity training). Both were inconclusive regarding the impact of these different protocols on the age at which children started to walk. There is insufficient evidence to determine whether treadmill intervention improves gross motor function (effect estimate 0.88; 95% CI: -4.54, 6.30). Conclusion. The current review provided only limited evidence of the efficacy of treadmill intervention in children up to six years of age. Few studies have assessed treadmill interventions in young children using an appropriate control group. The available evidence indicates that treadmill intervention may accelerate the development of independent walking in children with Down syndrome. Further research is needed to confirm this and should also address whether intensive treadmill intervention can accelerate walking onset in young children with cerebral palsy and high risk infants, and whether treadmill intervention has a general effect on gross motor development in the various subgroups of young children at risk for developmental delay
