Article Synopsis
  • The study explores the link between knee muscle strength, postural balance, and mobility in older women, aiming to identify fall risks and improve prevention programs.
  • Results showed that higher knee strength correlates with better functional mobility but only weakly relates to semi-static balance, indicating different coordination requirements for each activity.
  • Overall, findings suggest that improving knee strength can enhance mobility in elderly women, while maintaining balance may rely on different neuromuscular controls.

Objective: After deep brain stimulation (DBS), patients with Parkinson's disease (PD) typically still present significant gait and postural stability problems, and thus additional interventions are needed. In this way, our purpose was evaluate the comparative effectiveness of treadmill training, with and without body weight support, on balance outcomes among patients with PD after DBS.

Methods: Eleven patients with PD that were using bilateral subthalamic nucleus DBS were evaluated using Time Up and Go test (TUG); Berg Balance Scale (BBS) and Static Posturography.

Introduction: An accurate assessment of balance problems is critical for decreasing the risk of falling in patients with Parkinson's Disease (PD). Reliable diagnostic tools such as Computerized Dynamic Posturography (CDP) are not feasible for the clinical setting. Therefore, the present study's aim was to assess the correlation between the clinical Balance Evaluation Systems Test (BESTest) and CDP.

Introduction: Advanced Glycation End-Products (AGEs) are a diverse group of highly reactive molecules that play a vital role in the development of neurodegenerative disorders, such as Parkinson's Disease (PD), leading to a decline in functional and cognitive capacity. The objective of this study was to assess the intake and quantification of AGEs in individuals with PD and to correlate them with their functional and cognitive abilities.

Methods: This was a cross-sectional study involving 20 PD patients and 20 non-PD individuals as the Control group (C).

The ability to drive depends on the motor, visual, and cognitive functions, which are necessary to integrate information and respond appropriately to different situations that occur in traffic. The study aimed to evaluate older drivers in a driving simulator and identify motor, cognitive and visual variables that interfere with safe driving through a cluster analysis, and identify the main predictors of traffic crashes. We analyzed the data of older drivers (n = 100, mean age of 72.

Introduction: The main causes of amputation include vascular diseases, trauma, cancer, and congenital limb abnormalities. The person with transtibial amputation (TA) is affected by a greater cardiorespiratory, metabolic, and muscular load to walk and perform daily activities. The sedentary lifestyle contributes to the process of chronic non-communicable diseases.

Context: Many studies show the importance of evaluating the adaptation time of subjects in a virtual driving environment, looking forwards to a response as closest as a possible real vehicle.

Objectives: This study aimed to identify and analyze the adaptation to the driving simulator in older adults and middle-aged adults with and without a distraction, and a secondary aim was to identify predictors of safe performance for older adults' drives.

Design: Male and female middle-aged adults (n = 62, age = 30.

Context: Anterior Cruciate Ligament (ACL) injury is disabling in several sports because it causes knee instability and functional deficit. Usually, surgical treatments produce the best functional outcomes, however, sometimes they are not always able to fully restore stability and function.

Objective: The objective of this study was to evaluate postural balance, muscle strength, and functional performance of young athletes with an ACL injury before and after ACL reconstruction.

Context: Aging causes a progressive worsening in postural balance, affecting functional independence and increasing the risk of falls.

Objective: The aim of the study was to evaluate the effect of aging on the static balance in women from 50-years to 89-years of age.

Design: This was a cross-sectional study, with 400 irregularly active women were evaluated and grouped by age: Group 6 decade (age 50 to 59) ‒ 58 participants; Group 7 decade (age 60 to 69) ‒ 214 participants; Group 8 decade (age 70 to 79) ‒ 92 participants; Group 9 decade (age 80 to 89) ‒ 36 participants.

Background: Several studies have shown persistent postural control deficits and rotatory instability in patients after isolated Anterior Cruciate Ligament (ACL) reconstruction. There is evidence to support that the Anterolateral Ligament (ALL) plays an important role in the remaining anterolateral rotatory laxity of the knee. There are no further evidences in order to understand how patients with a combined ACL + ALL reconstruction surgery indication behave regarding postural control.

COVID-19 is an acute respiratory illness with higher mortality in older adults. This condition is spread person-to-person through close contact, and among policies employed to decrease transmission are the improvement of hygiene habits and physical distancing. Although social distancing has been recognized as the best way to prevent the transmission, there are concerns that it may promote increased depression symptoms risk and anxiety, mainly in older adults.
