Funções neuropsicológicas de escolares na reabertura das escolas brasileiras na pandemia da Covid-19 / The neuropsychological functions of schoolchildren after the reopening of brazilian schools during the Covid-19 pandemic

RESUMO Objetivo O objetivo desse estudo foi analisar as funções neuropsicológicas de estudantes de uma escola pública do Distrito Federal (Brasil), matriculadas 1º e 2º ano de Ensino Fundamental na reabertura das escolas públicas na pandemia da COVID-19 e a influência dos fatores familiares e contextuais sobre o desempenho dessas habilidades. Métodos Participaram 117 estudantes, bem como seus responsáveis. As crianças foram avaliadas presencialmente por meio do Instrumento de Avaliação Neuropsicológica Breve Infantil (NEUPSILIN-Inf). Os pais/responsáveis responderam remotamente ao Inventário de Recursos do Ambiente Familiar e as questões para classificação socioeconômica e de escolaridade materna. Resultado Os dados apontam alta prevalência de crianças em fase de alfabetização que apresentam alerta ou déficit das funções de orientação, memória, linguagem, habilidades visuoespaciais, habilidades aritméticas e fluência verbal. Ainda, as atividades previsíveis que sinalizam algum grau de estabilidade na vida familiar são preditoras do desempenho das crianças na habilidade de orientação e os recursos que promovem processos proximais refletem significativamente no desempenho em linguagem. Os resultados sugerem que crianças inseridas em família com estimativas da renda domiciliar abaixo de um salário mínimo apresentam piores desempenhos do controle inibitório. Conclusão Foram apresentados e discutidos os impactos das alterações das habilidades neuropsicológicas para o aprendizado das crianças, destacando a necessidade de intervenções imediatas e direcionadas para essas funções. Foram considerados os fatores contextuais que apresentaram influência sobre o desempenho das habilidades neuropsicológicas.

ABSTRACT Purpose The objective of this study was analyzed the neuropsychological functions of students from a public school in Brazil, enrolled in the 1st and 2nd year of Elementary School at the time of the reopening of schools during the COVID-19 pandemic and to access the influence of family and contextual information on the performance of these skills. Methods 117 students participated in the study, as well as their parents or guardians. The children were evaluated in person using the Brief Child Neuropsychological Assessment Instrument (NEUPSILIN-Inf). The parents/guardians answered remotely the Inventory of Resources of the Family Environment and questions about socioeconomic classification and maternal education. Results The data showed a high prevalence of children who had problems or deficits in the functions of orientation, memory, language, visuospatial skills, arithmetic skills and verbal fluency. Furthermore, predictable activities that signal some degree of stability in family life are predictors of children's performance in orientation skills and resources that promote proximal processes significantly reflect on language performance. The results suggest that children included in families with a household income below one Brazilian minimum monthly salary presented poorer inhibitory control performances. Conclusion The impact of changes in neuropsychological skills in children's learning were presented and discussed, highlighting the need for immediate and targeted intervention of these functions. Contextual factors that influenced the performance of neuropsychological skills were also considered.

Nível de atividade física, capacidade funcional e flexibilidade de soldados ingressantes no Exército brasileiro / Level of physical activity, functional capacity and flexibility of soldiers entering the Brazilian Army

Objetivou avaliar o nível de atividade física, capacidade funcional (CF) e a flexibilidade de adultos jovens antes e após dez meses de ingresso em um programa de exercícios físicos no Exército brasileiro. Trata-se de uma pesquisa de coorte prospectivo. O nível de atividade física foi avaliado pelo Questionário Internacional de Atividade Física (IPAQ), a CF, pelo Teste de Cooper, e a flexibilidade, pelo Banco de Wells. Amostra (n = 198; 18±0,27 anos) com índice de massa corporal (IMC) de 23,23±3,84 kg/m2. Após dez meses de admissão no Exército, constatou-se redução na prevalência de sedentarismo (33  28%) e na CF (2.982±243,61  3.117±192,87 m), sem alteração da flexibilidade (27,31±7,39  27,52±7,40 cm). Houve grande tamanho de efeito no IMC, na relação cintura quadril (RCQ) e na flexibilidade. Conclui-se que a inserção em um programa de exercícios físicos no Exército brasileiro aumentou a CF e reduziu a RCQ dos jovens.

This study aimed to evaluate the level of physical activity, functional capacity (FC), and flexibility of young adults before and ten months after joining a physical exercise program in the Brazilian Army. This was a prospective cohort study. The level of physical activity was assessed using the International Physical Activity Questionnaire (IPAQ), FC using the Cooper Test, and flexibility using the Wells bench. Sample (n = 198; 18±0.27 years) with a body mass index (BMI) of 23.23±3.84 kg/m2. After ten months of admission to the Brazilian Army, there was a reduction in the prevalence of sedentary lifestyle (33  28%) and FC (2,982±243.61  3,117±192.87 m), without change in flexibility (27.31±7.39  27.52±7.40 cm). There was a large effect size on BMI, waist-hip ratio (WHR), and flexibility. In short, inclusion in a physical exercise program in the Brazilian Army increased FC and reduced the WHR of young recruits.

Do Improved Trunk Mobility and Isometric Strength Correlate with Improved Pain and Disability after Multimodal Rehabilitation for Low Back Pain? / A melhora da mobilidade e da força isométrica do tronco se correlacionam com a melhora da dor e da incapacidade após a reabilitação multimodal para dor lombar?

Abstract Objective To determine the correlation between posttreatment trunk range of motion (ROM) and isometric strength (TIS) and pain and disability in patients who underwent multimodal rehabilitation for low back pain (LBP). Methods In this prospective cohort study, 122 patients undergoing multimodal rehabilitation for LBP were analyzed. The pre- and posttreatment numerical pain rating scale (NPRS) and the Oswestry disability index (ODI) scores, as well as trunk ROM and TIS were compared. The Pearson correlation was used to determine correlation between posttreatment clinical outcomes and ROM and TIS. Results At the end of treatment, the mean NPRS (p< 0.0001) and ODI (p< 0.0001) scores, mean trunk extension (p< 0.0001), and flexion (p< 0.0001) ROMs improved significantly. Similarly, posttreatment, the mean extension (p< 0.0001) and flexion (p< 0.0001) TISs improved significantly. There was a weak correlation between the NPRS score and ROM extension (r = -0.24, p= 0.006) and flexion strength (r = -0.28, p= 0.001), as well as between the ODI score and TIS extension (r = -0.30, p= 0.0007) and flexion (r = -0.28, p= 0.001). Conclusion Despite significant improvement in pain, disability, trunk ROM, and TIS with multimodal treatment, there was a weak correlation between posttreatment pain and function and trunk ROM and TIS. Improvement in pain and function with physical rehabilitation treatment for LBP is a complex phenomenon and needs further investigation.

Resumo Objetivo Determinar a correlação entre a amplitude de movimento (ADM) do tronco pós-tratamento e a força isométrica do tronco (FIT) e a dor e a incapacidade em pacientes submetidos à reabilitação multimodal para dor lombar (DL). Métodos Neste estudo de coorte prospectiva, 122 pacientes submetidos à reabilitação multimodal para DL foram analisados. Foram comparados os escores de escala numérica de dor pré- e pós-tratamento (END) e do índice de incapacidade Oswestry (Oswestry disability index - ODI), a ADM do tronco e a FIT. A correlação de Pearson foi utilizada para determinar a correlação entre desfechos clínicos e a ADM e a FIT pós-tratamento. Resultados Ao final do tratamento, as médias de ADM (p< 0,0001) e ODI (p< 0,0001), as ADMs médias de extensão (p< 0,0001) e a flexão (p< 0,0001) do tronco melhoraram significativamente. Da mesma forma, a FIT pós-tratamento, as FITs médias de extensão (p< 0,0001) e flexão (p< 0,0001) melhoraram significativamente. Houve uma correlação fraca entre o escore do END e a ADM de extensão (r = -0,24, p= 0,006) e força de flexão (r = -0,28, p= 0,001) pós-tratamento, assim como entre o escore de ODI e FIT de extensão (r = -0,30, p= 0,0007) e flexão (r = -0,28, p= 0,001) pós-tratamento. Conclusão Apesar da melhora significativa da dor, capacidade, ADM do tronco e FIT com tratamento multimodal, houve uma fraca correlação entre dor pós-tratamento e função e ADM e FIT de tronco. A melhora da dor e da função com o tratamento de reabilitação física para DL é um fenômeno complexo e precisa de uma investigação mais aprofundada.

Relación entre flexibilidad, fuerza y VO2max de los deportistas de Imbabura

Las cualidades de la condición física como la flexibilidad, fuerza y VO2max en el deportista, se manifiestan en su totalidad en cualquier actividad deportiva. El objetivo de la investigación fue evaluar el nivel de flexibilidad y la relación existente con el nivel de fuerza explosiva y VO2max. Se seleccionaron 137 deportistas de la provincia de Imbabura en las disciplinas de fútbol, basquetbol, escalada, atletismo, ciclismo y taekwondo y se evaluaron mediante la prueba de sit and reach, salto vertical (VERT) y test de Queen College. Los resultados mostraron que el 81,8% fueron de etnia mestiza, el 56 % de la muestra de género masculino. Las disciplinas taekwondo y escalada fueron más flexibles (31 cm), la fuerza explosiva promedio que destacó fue la escalada (48cm) de capacidad de salto, seguido del basquetbol (45cm); el VO2max de los basquetbolistas fue excelente (57 ml*kg-1*min-1). El fútbol presentó un VO2max promedio (52,8 ml*kg-1*min), con diferencias significativas entre las medias (p=<0,05). La flexibilidad de las disciplinas deportivas tuvo una relación (p=<0,00) directa moderada con la fuerza e inversa moderada (p=<0,01/ rho =-0,4) con el VO2max. La flexibilidad fue directamente proporcional a la fuerza, es decir, si aumentó la flexibilidad también aumentó la fuerza; sin embargo, la flexibilidad fue inversamente proporcional a el VO2max, es decir, la flexibilidad disminuyó y el VO2 max aumentó.

As qualidades de aptidão física como flexibilidade, força e VO2max no atleta se manifestam em sua totalidade em qualquer atividade esportiva. O objetivo da pesquisa era avaliar o nível de flexibilidade e a relação existente com o nível de força explosiva e VO2max. Um total de 137 atletas foram selecionados da província de Imbabura nas disciplinas de futebol, basquete, escalada, atletismo, ciclismo e taekwondo e foram avaliados usando o teste sit and reach, salto vertical (VERT) e o teste Queen's College. Os resultados mostraram que 81,8% eram de etnia mista, 56% da amostra era masculina. As disciplinas de taekwondo e escalada eram mais flexíveis (31 cm), a força explosiva média que se destacava era a capacidade de saltar (48 cm), seguida do basquetebol (45 cm); o VO2max dos jogadores de basquetebol era excelente (57 ml*kg-1*min-1). O futebol tinha um VO2máx médio (52,8 ml*kg-1*min-1), com diferenças significativas entre os meios (p=<0,05). A flexibilidade das modalidades esportivas teve uma relação direta moderada (p=<0,00) com força e uma relação inversa moderada (p=<0,01/ rho =-0,4) com o VO2max. A flexibilidade foi diretamente proporcional à força, ou seja, se a flexibilidade aumentou, a força também aumentou; entretanto, a flexibilidade foi inversamente proporcional ao VO2máx, ou seja, a flexibilidade diminuiu e o VO2máx aumentou.

The qualities of the physical condition such as flexibility, strength and VO2max in the athlete, are fully manifested in any sporting activity. The objective of the research was to evaluate the level of flexibility and the existing relationship with the level of explosive strength and VO2max. One hundred thirty-seven athletes from the province of Imbabura were selected in the disciplines of soccer, basketball, climbing, athletics and taekwondo and were evaluated through the sit and reach test, vertical jump (VERT) and Queen College test. The results showed that 81.8 % were of mixed ethnicity, 56 % of the sample male. The taekwondo and climbing disciplines were more flexible (31 cm), the average explosive strength that stood out was climbing (48cm) of jumping capacity, followed by basketball (45cm); the VO2max of the basketball players was excellent (57 ml*kg-1*min-1). Soccer presented an average VO2max (52.8 ml*kg-1*min), with significant differences between the means (p=<0.05). The flexibility of the sports disciplines had a moderate direct relationship (p=<0.00) with strength and a moderate inverse relationship (p=<0.01/ rho =-0.4) with VO2max. Flexibility was directly proportional to strength, that is, if flexibility increased, strength also increased; however, flexibility was inversely proportional to VO2max, that is, flexibility decreased and VO2max increased.

Terapia a laser de alta intensidade para rigidez muscular dos isquiotibiais: fundamentação e desenho do estudo para estudo controlado randomizado simples-cego / High-intensity laser therapy for hamstring muscle tightness: rationale and study design for a single-blinded randomized controlled trial

CONTEXTO: Sentar-se por muito tempo e um estilo de vida sedentário podem resultar em encurtamento dos isquiotibiais. Um declínio na atividade física regular pode levar a uma diminuição da flexibilidade do músculo em um adulto mais jovem. Aumentar a flexibilidade dos músculos isquiotibiais pode diminuir as possibilidades de lesões e prevenir a dor lombar. A aplicação da terapia a laser de alta intensidade (TLAI) tem demonstrado inúmeros benefícios para diversas condições. No entanto, até o momento, não hápesquisas publicadassobre a eficácia dessaterapia para melhorar o comprimento dos músculos isquiotibiais em adultos jovens saudáveis. Este artigo descreve o protocolo de estudo para investigar os benefícios do TLAI no tratamento da rigidez muscular dos isquiotibiais em adultos jovens. MÉTODOS: 136 indivíduos jovens saudáveis serão recrutados, pelo método de amostragem intencional, para participar de um estudo randomizado, simplescego e controlado por simulação. Os participantes recrutados serão divididos aleatoriamente em dois grupos, o grupo TLAIativo e o grupo TLAI placebo. A duração do tratamento será de 8 a 10 minutos por sessão em ambos os membros inferiores, em dias alternados, durante duas semanas. O teste de extensão ativa do joelho e o teste de sentar e tocar são as medidas de resultado que serão registradas na linha de base, no final do período pós-intervenção de 2 semanas. O valor de p ≤0,05 será considerado estatisticamente significativo. DISCUSSÃO: Os resultados do estudo fornecerão os dados para determinar se aTLAI seria uma futura intervenção não farmacológica não invasiva para reduzir a tensão muscular dos isquiotibiais em adultos jovens. REGISTRO DE ENSAIO: Registro de Ensaios Clínicos NCT05077761.

BACKGROUND: Prolonged sitting and a sedentary lifestyle may result in hamstring shortness. A decline in regular physical activity could lead to a decrease in the flexibility of the muscle in a younger adult. Increasing hamstring muscle flexibility could decrease the possibility of injuries and prevent low back pain. The application of high-intensity laser therapy (HILT) has proved to be innumerable benefits for many conditions. However, to date, no published research is available on the effectiveness of this therapy in improving hamstring muscle length in healthy young adults. This article describes the study protocol for investigating the benefits of HILT in treating hamstring muscle tightness among young adults. METHODS: 136 healthy young individuals will be recruited, by purposive sampling method, to participate in a randomized, single-blinded, sham-controlled study. Recruited participants will be randomly divided into two groups, the active HILT group, and the sham HILT group. The treatment duration will be 8-10 minutes per session, on both lower limbs, for alternate days a week, for two weeks. The active knee extension test and sit-toe and touch test are the outcome measures that will be recorded at baseline, end of the 2-week post-intervention period. The p-value ≤0.05 will be considered statistically significant. DISCUSSION: The study findings will provide the data to determine whether HILT would be a future non-pharmacological non-invasive intervention to reduce hamstring muscle tightness among young adults. TRIAL REGISTRY: Clinical Trials Registry NCT05077761.

Effect of online acceptance and commitment therapy group intervention on psychological flexibility of undergraduate students with facial negative physical self / 中华行为医学与脑科学杂志

Objective:To investigate the effect of online acceptance and commitment therapy(ACT) group intervention on psychological flexibility of undergraduate students with facial negative physical self.Methods:From March to June 2022, thirty-two undergraduates with facial negative physical self-image were recruited, assessed and selected from a university in Zhejiang Province.The subjects were randomly divided into the training group( n=16) and the control group( n=16). The training group received 20 days of online ACT group intervention, while the control group kept waiting.The cognitive fusion questionnaire(CFQ), acceptance and action questionnaire version Ⅱ(AAQ-Ⅱ) and negative physical self scale-face(NPSS-F) were used to measure the two groups before and after intervention and 1 month after intervention.Repeated measurement analysis of variance(ANOVA) conducted was used to compare scale results with SPSS 26.0. Results:(1)The interaction effect between group and time of CFQ scores was statistically significant( F(1.625, 48.755)=4.316, P=0.025, ηp2=0.126). After intervention, the CFQ score of the training group was significantly lower than those of the control group(34.38±8.66, 40.94±8.82, P<0.05). The CFQ scores of the training group after intervention and 1 month after intervention(36.00±9.49) were both significantly lower than those before intervention(41.87±8.72, all P<0.05). (2)The interaction effect between group and time of AAQ-Ⅱ scores was marginally statistically significant( F(2, 29)=3.009, P=0.065, ηp2=0.172). After intervention, the AAQ-Ⅱ score of the training group was significantly lower than those of the control group(24.12±4.97, 28.69±6.78, P<0.05). The AAQ-Ⅱ score of the training group after intervention was significantly lower than those before intervention(28.75±6.11, P<0.05). (3)The interaction effect between group and time of NPSS-F scores was not statistically significant( F(2, 29)=1.509, P=0.238, ηp2=0.094), while the main effect of time was marginally statistically significant between the two groups( F(2, 29)=3.315, P=0.051, ηp2=0.186). The NPSS-F score of the training group after intervention was significantly lower than those before intervention(16.06±6.67, 18.81±7.85, P<0.05). Conclusion:Online ACT group intervention can effectively reduce the cognitive fusion and experiential avoidance of undergraduate students with facial negative physical self, then can improve their psychological flexibility.

Differences of resting-state brain functional connectivity in patients with early-onset and late-onset obsessive compulsive disorder and their correlation with cognitive flexibility / 中华行为医学与脑科学杂志

Objective:To explore the differences of the resting-state functional connectivity(FC) between goal-directed network and habituation networks in patients with early- and late-onset obsessive compulsive disorder (OCD) and the correlation between the strength of FC in the differential brain regions and cognitive flexibility.Methods:From October 2019 to April 2021, 40 patients with OCD were included in this study, including 22 patients with early-onset OCD and 18 patients with late-onset OCD.The cognitive flexibility of all subjects was assessed using the Wisconsin card sorting test (WCST), the Stroop task and the trail making test (TMT). The brain regions which were associated with goal-directed network(caudate, orbitofrontal cortex, ventromedial prefrontal cortex, and anterior cingulate cortex) and the brain regions which were associated with habituation network(putamen, supplementary motor area and insula) were selected as FC regions of interest (ROI). The DPABI and SPM12 plug-ins in the matlab2011a platform were used for whole brain FC analysis to compare the difference of FC between patients with early-onset OCD and patients with late-onset OCD on the two networks.The data were analyzed by SPSS 25.0 with χ2 test, independent samples t-test, and Pearson correlation analysis. Results:Compared with patients with early-onset OCD, patients with late-onset OCD had significantly enhanced FC of the left supplementary motor area with the left putamen and left insula.The total number of persistent errors of WCST in patients with late-onset OCD was greater than that in patients with early-onset OCD ((20.61±11.30), (14.95±8.94), P<0.05). The FC of the left putamen-left supplementary motor area was significantly and positively correlated with the total number of sustained responses ( r=0.678, P=0.003) and the total number of incorrect responses ( r=0.590, P=0.013) in patients with late-onset OCD.The FC of the left supplementary motor area-left insula was significantly positively correlated with the number of responses required to complete the first classification in patients with late-onset OCD ( r=0.485, P=0.049). Conclusion:Patients with late-onset OCD have stronger habituation network FC than patients with early-onset OCD, and the enhanced FC correlates with patients' cognitive flexibility performance, while late-onset OCD has more impaired cognitive flexibility than early-onset OCD.

Relationship between self-esteem and mental health of medical students: mediating effect of psychological flexibility / 中华医学教育探索杂志

Objective:To explore the relation among self-esteem, psychological flexibility and mental health in medical students, and to provide scientific reference for mental health education for medical students.Methods:A total of 788 medical students selected from a medical university in Chongqing City were investigated with the symptom checklist 90 (SCL-90), self-esteem scale (SES), acceptance and action questionnaire-Ⅱ (AAQ-Ⅱ), and cognitive fusion questionnaire-fusion (CFQ-F). SPSS 22.0 software was used for statistical analysis. T test, ANOVA, correlation analysis and tests for mediation effects were conducted. Results:There were significant differences in self-esteem and mental health level among medical students in gender and different grades ( t=-2.55, P<0.05; F=6.53, P<0.05). Mental health, self-esteem and psychological flexibility of medical students were correlated in pairs ( r=-0.528-0.694, P<0.01). Psychological flexibility played a partial mediation role between self-esteem and mental health of medical students, and the mediating effect accounted for 60.03% of the total effect. Conclusion:Self-esteem can directly predict the mental health of medical students, and can also indirectly affect mental health through psychological flexibility. Medical universities should carry out psychological education and promotion work with pertinence.

Objective:To explore the intervention effect of acceptance and commitment therapy on the psychological flexibility, self-compassion, anxiety and depression of the primary caregivers of patients with primary liver cancer, so as to provide reference for the clinical care of the primary caregivers of cancer patients.Methods:This was a prospective study. A total of 80 primary caregivers of patients with primary liver cancer treated in Tianyou Hospital Affiliated to Wuhan University of Science and Technology from July to December 2021 were selected as the observation objects, and they were randomly divided into the control group and the intervention group according to the random drawing method, with 40 cases in each group. The control group was given routine nursing measures, while the intervention group was given acceptance and commitment therapy on the basis of routine nursing. The intervention effect was evaluated by the Acceptance and Action Questionnaire-2nd Edition (AAQ-Ⅱ), Self-Compassion Scale Short-Form (SCS-SF) and Hospital Anxiety and Depression Scale (HADS) before the intervention, on the day of discharge, and one month after discharge.Results:Finally, 71 primary caregivers completed the intervention and follow-up, 36 in the control group and 35 in the intervention group. Before the intervention, there was no statistically significant difference in the scores of AAQ-Ⅱ, SCS-SF, Anxiety subscale of HADS(HADS-A) and Depression subscale of HADS(HADS-D) between the two groups ( P>0.05). The AAQ-Ⅱscores of the intervention group on the day of discharge and one month after discharge were (19.63±2.59), (19.12 ± 2.20) points, which were significantly lower than those of the control group (23.14 ± 2.49), (22.56 ± 2.40) points. The differences were statistically significant ( t=5.83, 6.25, both P<0.01). The SCS-SF scores of the intervention group on the day of discharge and one month after discharge were (39.34 ± 2.68), (39.89 ± 2.81) points, which were significantly higher than those of the control group (36.69 ± 3.08), (37.72 ± 2.41) points, the differences were statistically significant ( t=-3.86, -3.49, both P<0.01). The HADS-A/HADS-D scores of the intervention group on the day of discharge and one month after discharge were (9.31 ± 1.95), (9.09 ± 1.60) points and (8.80 ± 2.15), (8.54 ± 1.75) points,which were significantly lower than those of the control group(11.42 ± 1.50), (11.03 ± 1.70) points and (10.11 ± 1.92), (10.03 ± 1.84) points, the differences were statistically significant( t values were 2.71-5.10, all P<0.01). The scores of AAQ-Ⅱ, SCS-SF, HADS-A and HADS-D of the two groups were analyzed by repeated measures analysis of variance, and there were significant differences in time effect, inter-group effect and interaction effect ( F vaules were 3.42-37.90, all P<0.05). Conclusions:Acceptance and commitment therapy can improve the self-compassion and psychological flexibility, reduce anxiety and depression of the primary caregivers of patients with primary liver cancer.

There were 6 males and 22 females with an average age of 69.5 years (range, 56-92 years). The injured vertebra were located at T 10-L 2, including 11 cases of single thoracic fracture, 11 cases of single lumbar fracture, and 6 cases of multiple thoracolumbar fractures. The disease duration ranged from 3 weeks to 36 months, with a median of 5 months. All patients received examinations of BFB-CT and standing lateral full-spine X-ray (SLFSX). The thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), local kyphosis of injured vertebra (LKIV), lumbar lordosis (LL), and the sagittal vertical axis (SVA) were measured. Referring to the calculation method of scoliosis flexibility, the kyphosis flexibility of thoracic, thoracolumbar, and injured vertebra were calculated respectively. The sagittal parameters measured by the two methods were compared, and the correlation of the parameters measured by the two methods was analyzed by Pearson correlation.@*RESULTS@#Except LL ( P>0.05), TK, TLK, LKIV, and SVA measured by BFB-CT were significantly lower than those measured by SLFSX ( P<0.05). The flexibilities of thoracic, thoracolumbar, and injured vertebra were 34.1%±18.8%, 36.2%±13.8%, and 39.3%±18.6%, respectively. Correlation analysis showed that the sagittal parameters measured by the two methods were positively correlated ( P<0.001), and the correlation coefficients of TK, TLK, LKIV, and SVA were 0.900, 0.730, 0.700, and 0.680, respectively.@*CONCLUSION@#Thoracolumbar kyphosis secondary to old osteoporotic vertebral compression fracture shows an excellent flexibility and BFB-CT in simulated surgical position can obtain the remaining real angle which need to be corrected surgically.

Evidências de validade do teste informatizado para avaliação das funções executivas / Evidence of validity of the computerized test for evaluating executive functions / Evidencia de validez de la prueba computarizada para evaluación de funciones ejecutivas

Funções executivas (FE) referem-se ao conjunto de habilidades que, de forma integrada, coordenam o comportamento e a cognição. Assim, o comprometimento no desenvolvimento das FE está ligado a vários desfechos negativos ao longo da vida. Portanto, a avaliação dessas habilidades na infância é essencial para identificar e prevenir prejuízos na vida adulta. Este estudo teve como objetivo investigar evidências de validade do Teste Informatizado para Avaliação das Funções Executivas (Tafe) pelo critério de idade e pelo padrão de correlação entre medidas do TAFE e outras medidas de FE. Para isso, foi utilizada uma amostra de 51 crianças, entre 4 e 10 anos de idade, matriculadas em uma escola privada na cidade de Goiânia (GO), da pré-escola ao 4º ano do ensino fundamental. Como instrumentos, foram utilizados, além do Tafe, as tarefas de Bloco de Corsi, Teste de Trilhas A e B, Teste de Trilhas Pré-Escolares, Teste de Stroop Pré-Escolares e Subteste Dígitos da Escala Wechsler de Inteligência. Foram conduzidas análises estatísticas Kruskal Wallis para verificar a evidência de validade por relação com idade e análises de correlação não paramétrica de Spearman para avaliar as evidências de validade convergente. O instrumento investigado mostrou-se efetivo para discriminar entre as diferentes faixas etárias, assim, sensível ao desenvolvimento das FE. Os resultados obtidos no Tafe correlacionaram-se aos obtidos em outros testes que também avaliaram FE, mostrando claros padrões de convergência. Logo, as análises dos resultados fornecem evidências de validade ao Tafe, derivadas a partir de diferentes estratégias de investigação.(AU)

Executive functions (EF) refer to the set of skills that, in an integrated way, coordinate behavior and cognition. Thus, the commitment in developing EF is linked to several negative outcomes throughout life. Therefore, the assessment of these abilities in childhood is essential to identify and prevent possible harm in adult life. This study aimed to investigate evidences of validity of the Computerized Test for Evaluation of Executive Functions (TAFE) by the age criterion and by the pattern of correlation between TAFE measures and other EF measures. To this end, a sample of 51 children, between 4 and 10 years old, enrolled in a private school in the municipality of Goiânia (GO), from preschool to the 4th year of elementary school, was used. As instruments, in addition to TAFE, the tasks of Corsi Block, Trails Test A and B, Preschool Trails Test, Preschool Stroop Test and the Digits Subtest of the Wechsler Intelligence Scale were used. Kruskal Wallis statistical analyzes were conducted to verify the evidence of validity by age criteria and Spearman's nonparametric correlation analysis to assess evidence of convergent validation. The instrument investigated was effective to discriminate between different age groups, thus being sensitive to the development of EF. The results obtained in TAFE were correlated with those obtained in other tests that also assess FE, showing patterns of convergence. Therefore, the analysis of the results provides validation evidence to TAFE, derived from different investigation methods.(AU)

Relationship between lower limb muscle strength and walk speed in community dwelling older adults: the chain mediating role of flexibility and dynamic balance / 中国康复理论与实践

ObjectiveTo investigate the relationship between lower limb muscle strength and walking speed in older adults, and to analyze the mediating role of flexibility and dynamic balance. MethodsFrom November to December, 2021, a total of 155 older adults at the Shanghai Senior Sports and Health Home were included. Their basic health information was collected, and the lower limb muscle strength, flexibility, dynamic balance and walking speed were tested. A mediated effects analysis was conducted. ResultsThere was a pairwise correlation among lower limb muscle strength, flexibility, dynamic balance and walking speed in older adults (r > 0.210, P < 0.01). In the mediated effects model, after controlling for age and gender, lower limb muscle strength did not directly predict walking speed in older adults (β = 0.029, P = 0.699), however, lower limb muscle strength could influence walking speed through the partial mediation of dynamic balance (effect = 0.0130, 95% CI 0.0073~0.0197) and the chain mediation of lower flexibility and dynamic balance (effect = 0.0019, 95% CI 0.0003~0.0043). ConclusionLower limb muscle strength can indirectly affect walking speed in older adults through the mediators of flexibility and dynamic balance, or the dynamic balance alone.

Characteristics of health-related physical fitness of patients with chronic neck pain / 中国康复理论与实践

ObjectiveTo investigate the characteristics of health-related physical fitness of patients with chronic neck pain, and the relationship between neck pain and physical fitness. MethodsFrom Match to June, 2020, 30 healthy controls and 30 patients with chronic neck pain in Dalian University of Technology were included. They were assessed with Neck Disability Index (NDI) and Visual Analog Scale for pain (VAS). The body composition, grip strength (dominant), shoulder joint flexibility, cardiopulmonary endurance and neck muscle endurance of all the participants were measured. ResultsThe content of standardized subcutaneous fat was more, and the trunk muscle content was less in the patients than in the healthy controls, while the standardized grip strength, endurance of neck flexor and extensor, right shoulder flexibility, absolute maximum oxygen uptake were all poorer (|t| > 2.088, P < 0.05). The score of VAS correlated (P < 0.05) with the score of NDI score (r = 0.407), grip strength (r = -0.406), endurance of neck extensor (r = -0.384), right shoulder joint flexibility (r = -0.551) and absolute value of maximal oxygen uptake (r = -0.510). ConclusionHealth-related physical fitness has been impaired for patients with chronic neck pain, and correlates with the intensity of pain.

Curso Temporal de los Efectos Agudos de una Sesión de Estiramiento Muscular en Sujetos Jóvenes y Sanos / Time Course of the Acute Effects of a Muscle Stretching Session in Young and Healthy Subjects

Introducción. La duración de los efectos agudos del estiramiento muscular y su relación con el volumen total de estiramiento es un tema controversial. Método. Se distribuyeron aleatoriamente 29 varones jóvenes y deportistas en tres grupos: Control, "protocolo corto" (5 estiramientos x 30' segundos) y "protocolo largo" (10 estiramientos x 30 segundos). Para medir el efecto se usó el Active Knee Extension Test en forma previa y posterior a los 0, 3, 7, 12, 18 y 25 minutos. Cada medición se grabó en video, y se identificó el rango máximo de estiramiento con el software Kinovea. Se realizó comparación pre y postintervención entre grupos e inter grupo. Se incorporó análisis post hoc en medidas repetidas. Resultados. No hubo diferencias en la medición preintervención entre los grupos (P=0,266). Ambos protocolos tuvieron cambios significativos (P<0,007) respecto del grupo control (P=0,65). Todas las mediciones postintervención comparadas con la preintervención presentan diferencias en el protocolo corto (P≤0,018) y largo (P≤0,009). Hubo diferencia entre el grupo control con el de protocolo corto (P≤0,014) y control con protocolo largo (P≤0,004) para todas las mediciones, y una diferencia entre ambos protocolos en el post inmediato (P=0,033) pero no para las mediciones posteriores (P≤0,139). Conclusión. Un protocolo de 150 segundos de estiramiento estático en isquiotibiales en varones asintomáticos jóvenes, presenta efectos por al menos 25 minutos. Al duplicar a 300 segundos sólo presenta diferencia en la medición inmediatamente posterior. Por lo tanto, ambos protocolos son igualmente efectivos, pero el protocolo corto es más eficiente.

Background. The duration of the acute effects of muscle stretching and its relationship with the total volume of stretching is a controversial issue. Methods. 29 young male athletes were randomly distributed into three groups: control, "short protocol" (5 stretches x 30'') and "long protocol" (10 stretches x 30''). To measure the effect, the Active Knee Extension Test was used before and after 0, 3', 7', 12', 18' and 25'. Each measurement was videotaped, and the maximum range of stretch was identified using the Kinovea software. A pre-post intervention comparison was made between groups and inter groups. Post hoc analysis was incorporated into repeated measures. Results. There were no differences in the pre-intervention measurement between the groups (P=0.266). Both protocols had significant changes (P<0.007) compared to the control group (P=0.65). All post-intervention measurements compared to pre-intervention present differences in the short (P≤0.018) and long (P≤0.009) protocol. There was a difference between the control group with the short protocol (P≤0.014) and the control group with the long protocol (P≤0.004) for all measurements, and a difference between both protocols in the immediate post (P=0.033) but not for the measurements. subsequent measurements (P≤0.139). Conclusion. A protocol of 150'' of static stretching in hamstrings in asymptomatic young men, presents effects for at least 25'. When doubling at 300'', it only presents a difference in the immediately subsequent measurement. Therefore, both protocols are equally effective, but the short protocol is more efficient.
