Purpose:The aim of the study was to determine whether corticospinal excitability and inhibition of the tibialis anterior during single-leg standing differs among individuals with chronic ankle instability (CAI),lateral ankle sprain copers,and healthy controls.Methods:Twenty-three participants with CAI,23 lateral ankle sprain copers,and 24 healthy control participants volunteered.Active motor threshold (AMT),normalized motor-evoked potential (MEP),and cortical silent period (CSP) were evaluated by transcranial magnetic stimula-tion while participants performed a single-leg standing task.Results:Participants with CAI had significantly longer CSP at 100％ of AMT and lower normalized MEP at 120％ of AMT compared to lateral ankle spraincopers (CSP100％:p 0.003;MEP120％:p 0.044) and controls (CSP100％:p 0.041;MEP120％:p 0.006).Conclusion:This investigation demonstrate altered corticospinal excitability and inhibition of the tibialis anterior during single-leg standing in participants with CAI.Further research is needed to examine the effects of corticospinal maladaptations to motor control of the tibial anterior on postural control performance in those with CAI.

宋词与宋代舞蹈密不可分,通常凭借宋舞概念、宋舞语言、宋舞风格再现宋代舞蹈,是研究宋代舞蹈的重要文献.鉴于此,文章分析宋词对宋代舞蹈的再现.其中,宋舞概念的再现,主要涉及宋舞场景、类型及表演主体;宋舞语言的再现,往往涉及描述宋代舞蹈的肢体动作;宋舞风格的再现,则关涉形式与创作理念两方面.宋词记录的宋代舞蹈实况再现了宋舞的部分真实面貌.
Purpose:The present study aimed to systematically review and compare 2 femoral autograft fixation techniques,namely,interference screws and suture anchors,for isolated medial patellofemoral ligament reconstruction in patients with recurrent patellofemoral
Purpose:This study aimed to determine the accuracy of a 4 split time modelling method to generate velocity-time and velocity-distance variables in elite male 100-m sprinters and subsequently to assess the roles of key sprint parameters with respect to 100
Objective:We reviewed and appraised the existing evidence of in vivo manifestations of residual force enhancement in human skeletal muscles and assessed,through a meta-analysis,the effect of an immediate history of eccentric contraction on the subsequent
Background:Accurate quantification of voluntary activation is important for understanding the extent of quadriceps dysfunction in individuals with anterior cruciate ligament reconstruction (ACLR).Voluntary activation has been quantified using both percent
折纸艺术是一种古老而又常新的艺术形式.它承载着丰富的文化内涵,集趣味性、装饰性、科学性与哲理性于一体,如今已广泛应用到人们生产生活的各个领域.文章主要通过分析国内外典型案例及设计实践等方式,探究折纸艺术在现代景观设计中的应用策略,从造型语言与空间形式、寓意象征与文化内涵,材料与结构应用这三个方面分析研究折纸艺术与景观设计相结合的规律与方法.折纸艺术以抽象化的独特的造型语言增强了景观设计的艺术性与感染力,打破了惯有的空间定义,创造出更加丰富的空间体验.折纸元素赋予景观场所深层次的寓意象征与文化内涵,以丰富的
Background:Team-sport players have a particularly high injury risk.Although female sex is considered a risk factor,it is still unknown whether female and male team-sport players,in fact,differ in their injury rates.We aimed to compare injury rates between
Background:Football is the most practised sport in the world and is associated with the risk of injuries in the players.Some studies have been published that identify injury prevention programs,but there is no review of the full body of evidence on injury
