Estudo de intervenção com escolares utilizando jogo de cartas "o enigma da pirâmide'' sobre alimentação saudável / Intervention study with schoolchildren using the card game "the pyramid enigma" about healthy eating / Estudio de intervención con escolares mediante el juego de cartas "el enigma de la pirámide" sobre alimentación saludable

RESUMO Objetivo: avaliar o conhecimento sobre alimentação saudável promovido pela tecnologia educacional. Método estudo de avaliação de desempenho, do tipo quase-experimental (desenho pré/pós- teste). Participaram 204 alunos, com idade entre nove e 10 anos, de três escolas públicas, de Recife-PE-Brasil, em setembro de 2018. Observou-se o ganho de conhecimento pelo seguinte processo: diminuindo da Pontuação Média Observada após a intervenção (PMO-2) a Pontuação Média Observada antes da intervenção (PMO-1); dividindo-se o número obtido pela PMO-1 e em seguida multiplicando o resultado obtido por 100. Resultados antes da intervenção 16/204 alunos (7,8%) obtiveram pontuação ≥ 7. Depois da intervenção, 160/204 alunos (78,4%) alcançaram essa pontuação. A proporção de alunos que pontuou ≤ 5 passou de 49/204 (24%) para 1/204 (0,5%). Quatro alunos mantiveram a pontuação inicial. O ganho médio de conhecimento após uma única jogada foi de 38,5%. Conclusão estes resultados comprovaram a efetividade do jogo, e seu emprego promoveu a socialização entre os alunos.

ABSTRACT Objective to evaluate the knowledge about healthy eating promoted by educational technology. Method quasi-experimental (pre/posttest design) performance evaluation study. test design). Participated 204 students, aged between nine and 10 years, from three public schools of Recife-PE-Brazil, in September 2018. Knowledge gain was observed by the following process: decreasing from the Mean Score Observed after the intervention (PMO-2) to the Mean Score Observed before the intervention (PMO-1); dividing the number obtained by PMO-1 and then multiplying the result obtained by 100. Results before the intervention 16/204 students (7.8%) scored ≥ 7. After the intervention 160/204 students (78.4%) achieved this score. The proportion of students who scored ≤ 5 went from 49/204 (24%) to 1/204 (0.5%). Four students maintained their initial score. The average knowledge gain after a single move was 38.5%. Conclusion these results proved the effectiveness of the game, and its use promoted socialization among the students.

RESUMEN Objetivo evaluar los conocimientos sobre alimentación saludable promovidos por la tecnología educativa. Método estudio de evaluación del rendimiento, de tipo cuasi-experimental (pre/postprueba). Participaron 204 alumnos, de entre nueve y diez años, de tres colegios públicos, de Recife-PE-Brasil, en septiembre de 2018. La ganancia de conocimientos se observó mediante el siguiente proceso: disminución de la puntuación media observada después de la intervención (PMO-2) a la puntuación media observada antes de la intervención (PMO-1); dividiendo el número obtenido por la PMO-1 y multiplicando luego el resultado obtenido por 100. Resultados antes de la intervención, 16/204 alumnos (7,8%) obtuvieron una puntuación ≥ 7. Después de la intervención, 160/204 alumnos (78,4%) alcanzaron esta puntuación. La proporción de estudiantes que obtuvieron una puntuación ≤ 5 pasó de 49/204 (24%) a 1/204 (0,5%). Cuatro estudiantes mantuvieron su puntuación inicial. La ganancia media de conocimientos tras un solo traslado fue del 38,5%. Conclusión estos resultados demostraron la eficacia del juego, y su uso promovió la socialización entre los estudiantes.

Contract-relax technique compared to static stretching in treating migraine in women: A randomized pilot trial.

INTRODUCTION: Physical therapy is often used by patients with headache, including modalities such as muscle stretching exercises. OBJECTIVES: To evaluate the feasibility of a pilot trial aimed at determining the efficacy of the proprioceptive neuromuscular facilitation (PNF) contract-relax technique compared to static stretching for treating migraineurs. METHODS: This pilot trial allocated 30 migraineur women (23 ±â€¯4 years) into PNF (n = 15) and static stretching groups (n = 15). The interventions were performed twice a week (16 sessions, 8 weeks). The feasibility outcomes included successful random allocation of 30 patients during a 12-month period, the proportion of eligible patients randomly assigned to each group, and the proportion of those who completed the 30-day follow-up. The outcomes of headache characteristics; medication intake; severity of migraine-related disability; neck disability; cervical mobility; pressure pain threshold; adverse effects and global perception of change were evaluated at baseline, after the end of treatment and after 30-day follow-up. RESULTS: The recruitment rate was 4.66% participants/month. The proportion of eligible patients randomly assigned to each group and for those who completed the 30-day follow-up was 88.23% and 100%, respectively. Both groups improved in headache-related outcomes. The perception of change was important for 67% of the PNF group and 47% of the static stretching group. No differences were found between groups regarding the studied outcomes. CONCLUSION: This is a feasible pilot trial. The PNF contract-relax technique was no more effective than static stretching for treating migraine, but both techniques improved the headache, the severity of migraine-related disability and the satisfaction after treatment.

Reproducibility of the pressure biofeedback unit in measuring transversus abdominis muscle activity in patients with chronic nonspecific low back pain.

The Pressure Biofeedback Unit (PBU) is often used by clinicians and researchers to indirectly evaluate transversus abdominis (TrA) muscle activity. The purpose of this study was to evaluate the inter and intra-examiner reproducibility of the PBU in measuring TrA muscle activity in fifty patients with chronic nonspecific low back pain. This study was performed using a test-retest design with a seven day interval. An Intraclass Correlation Coefficient (ICC(2,1)) of 0.74 (95% CI 0.54 to 0.85) and 0.76 (95% CI 0.58 to 0.86) was observed for the intra and inter-examiner reproducibility, respectively. The intra-examiner agreement (Limits of Agreement - LOA = 2.1 to -1.8 mmHg) and the inter-examiner agreement (LOA = 2.0 to -1.9 mmHg) were within the limits of agreement on 95% of occasions. The reproducibility of PBU in measuring TrA muscle activity in patients with chronic nonspecific low back pain ranged from satisfactory to excellent.
