GI and 78.9% in GII (p=0.334). The pain started during pregnancy in 75% in GI and in 73.3% in GII (p=0.784

Introdução: A Função Executiva é expressa nas atividades do dia a dia por meio do controle inibitório, memória de trabalho e da flexibilidade cognitiva. Apesar da importância de avaliar essas medidas, existem divergências sobre a reprodutibilidade dos testes. Objetivo: Testar a reprodutibilidade do Stroop Color-Word Test, Teste dos Cubos de Corsi e Teste de Trilhas em mulheres idosas. Métodos: Trinta e cinco mulheres idosas realizaram o Stroop Color-Word Test (Controle Inibitório), Teste dos Cubos de Corsi (Memória de Trabalho) e Teste de Trilhas (Flexibilidade Cognitiva) com uma semana entre o teste e reteste. A reprodutibilidade dos testes foi determinada pelo coeficiente de correlação intraclasse, coeficiente de variação, erro padrão da medida e inspeção visual dos gráficos de Bland-Altman. Resultados: O Stroop Color-Word Test apresentou valores satisfatórios quanto à reprodutibilidade apenas para as medidas congruentes e incongruentes, com valores excelentes de coeficiente de correlação intraclasse. O Teste dos Cubos de Corsi apresentou valores reprodutíveis com coeficiente de correlação intraclasse moderado e bom para a sequência e escore composto, respectivamente. O Teste de Trilhas apresentou valores reprodutíveis para as partes A, B e a razão (B/A), com coeficientes de correlação intraclasse entre moderado e bom. A inspeção visual nos gráficos de Bland-Altman demonstrou baixo viés em todas as variáveis. Conclusão: Os resultados do Stroop Color-Word Test, para ensaios congruentes e incongruentes, a sequência e o escore composto do Teste dos Cubos de Corsi, assim como a parte A, B e a razão (B/A) do Teste de Trilha são medidas reprodutíveis para mulheres idosas.

Introduction: Core stabilization training is pointed as an effective option for pain relief chronic non-specific low back pain (CNLBP), however, the adequate training volume to induce analgesia is still unknown. Objective: To evaluate the effect of one session of high and low volume core stabilization training protocols on endogenous pain modulation in women with CNLBP. Methods: This is an evaluator-blinded randomized crossover trial. Eighteen volunteers participated of the study, whom performed two core stabilization training sessions: high and low training volume. The variables evaluated were the pressure pain thresholds (PPT) and temporal summation (TS) by digital pressure algometer, in addition to the conditioned pain modulation (CPM) using a pressure algometer and ischemic compression with sphygmomanometer as conditioned stimulus. A 2x2 repeated measures ANOVA was performed to compare training and time, Bonferroni's post hoc test for pairwise comparison from interactions (time and training). Data were expressed as mean ± standard deviation and the significance level established in 5%. Results: When comparing pre and post intragroup, low volume core stabilization training showed significant increase at the PPT in L5 (p < 0.05) and tibialis anterior (p < 0.01). High volume training not showed a significant increase in none of the PPT measures. However, none of the investigated protocols changed TS and CPM in women with CNLBP. Conclusion: Low volume core stabilization training produces local analgesia and remote hypoalgesia, demonstrated by increased PPT in L5 and tibialis anterior. However, none of the investigated protocols were effective to reduce the central sensitization assessed by CPM and TS.

Exercise‐induced hypoalgesia (EIH) is characterized as the pain reduction after an exercise session and it seems to be related to the release of plasma β‐endorphin. In this sense, the core stabilization training (CT) has been suggested for patients with chronic nonspecific low back pain (CNSLBP), but it is unclear whether it induces EIH. Patients with CNSLBP have neuromotor dysfunctions that can affect the performance of functional tasks, thus, performing functional training (FT) could improve motor control and promote EIH, since functional training uses multi‐joint exercises that aim to improve the functionality of actions performed in daily life. EIH is usually assessed using quantitative sensory tests (QST) such as conditioned pain modulation, pressure pain threshold, and temporal summation. Thus, the sum of parameters from quantitative sensory tests and plasma β‐endorphin would make it possible to understand what the neuroendocrine effects of FT and CT session are. Our study compared the acute effect of CT and FT on the EIH and plasma β‐endorphin release, and correlated plasma β‐endorphin with quantitative sensory testing in patients with CNSLBP. Eighteen women performed two training sessions (CT and FT) with an interval of 48 h between sessions. EIH was assessed by QST and plasma β‐endorphin levels. Results showed that only FT significantly increased plasma β‐endorphin (FT p < 0.01; CT p = 0.45), which correlated with pain pressure threshold (PPT) and conditioned pain modulation (CPM). However, QST values were not different in women with CNSLBP after CT or FT protocols. Plasma β‐endorphin correlated with PPT and CPM, however, the same did not occur with a temporal summation.
