Background: Postural control deficits and persistent joint stability issues are prevalent in population with anterior cruciate ligament (ACL) injuries or reconstructions. Postural control is typically assessed using the center of pressure (CoP) parameters during the static single-leg stance with a force plate. However, previous studies have reported unclear definitions and descriptions of the CoP parameters, causing inconsistent results of postural control deficits in a specific population.

The Balance Error Scoring System (BESS) is commonly used to assess static balance in individuals with CAI. However, the sensitivity of BESS in detecting balance deficits in CAI is unknown.

We performed Mendelian randomization (MR) analysis to identify the causal effects of ligamentous knee injuries on the CST.
Hypothesis: Ligamentous knee injuries impair CST microstructure (ie, by reducing fractional anisotropy [FA] and increasing mean diffusivity [MD]).
Context: Structural evidence for corticospinal tract (CST) abnormality between patients with ACLR and healthy controls, and the relationships between CST structure and clinical features of the patients (e.g., objective sensorimotor outcomes, postoperative duration) are lacking.

Background: Chronic ankle instability (CAI) has been considered a neurophysiological disease, having as symptoms dysfunction in somatosensory and motor system excitability. Rehabilitation has been considered an effective treatment for CAI. However, few studies have explored the effects of rehabilitation on neuroplasticity in the CAI population.

It accounts for approximately 60-70% of all dementia cases worldwide. With the increasing number of AD patients, elucidating underlying mechanisms and developing corresponding interventional strategies are necessary.
View Article and Find Full Text PDFTo determine whether existing exercise therapies can restore the joint position sense (JPS) deficits of patients with chronic ankle instability (CAI) when compared with controlled non-training patients. Seven databases were searched using ankle, injury, proprioception, and exercise-therapy-related terms. Peer-reviewed human studies in English that used the absolute errors score of joint position reproduction (JPR) test to compare the JPS of injured ankles in CAI patients before and after exercise therapy and non-training controls were included and analyzed.
View Article and Find Full Text PDFContext: Postural control deficits arising from injured ankles are central to chronic ankle instability (CAI) and its persistent symptoms. This is usually measured by recording the center of pressure (CoP) trajectory during static single-leg stance using a stable force plate. However, existing studies have produced conflicting results on whether this mode of measurement adequately reveals the postural deficits in CAI.
View Article and Find Full Text PDFBackground: Pain plays an important role in chronic ankle instability (CAI), and prolonged pain may be associated with ankle dysfunction and abnormal neuroplasticity.
Purpose: To investigate the differences in resting-state functional connectivity among the pain-related brain regions and the ankle motor-related brain regions between healthy controls and patients with CAI, and explore the relationship between patients' motor function and pain.
Study Design: A cross-database, cross-sectional study.
Context: Chronic ankle instability (CAI) has been considered a neurophysiological condition, with dysfunctional somatosensory and motor system excitability. However, few researchers have explored the changes in cortical activation during balance tasks of patients with CAI.
Objective: To compare the cortical activity during single-legged stance among CAI, copers, and uninjured control participants and to compare dynamic balance across groups.
Objectives: Electrophysiological studies have revealed that abnormal function of the corticospinal pathway might contribute to chronic ankle instability, but structural evidence underlying the abnormality is lacking. The purpose of this study was to quantitate microstructural differences between corticospinal tracts in patients with chronic ankle instability and healthy controls.
Design: Cross-sectional.
Objective: Patients with chronic ankle instability (CAI) may experience ankle force sense deficits due to mechanoreceptor injury and proprioceptive deafferentation in the affected ankles. This study aimed to systematically review the literature and investigate (1) whether patients with CAI have impaired force sense when compared with uninjured contralateral sides or healthy controls, and (2) which characteristics of CAI (e.g.
View Article and Find Full Text PDFObjective: Individuals with chronic ankle instability experience recurring sprains and impaired proprioception, and the effect of external support in the proprioception of injured ankles is still inconsistent in existing studies. Therefore, this study aimed to investigate whether external support could enhance the proprioception of injured ankles in patients with chronic ankle instability.
Design: This was a systematic review and meta-analysis.
