Filter by:The purpose of this study is to determine the utility of a performance measure for the dual-task of gait and considering people with multiple sclerosis have both cognitive and motor problems, the secondary aim of this study is to determine the effectiveness of a gait-specific dual-tasking intervention for ambulatory individuals with multiple sclerosis.
Background: Dynamic balance keeps the vertical projection of the center of mass within the base of support while the center of mass moves. The age-related decrease in dynamic balance is a risk factor for falls. Dynamic balance tests are used to predict the risks for falls and eventual falls but the psychometric properties of most tests assessing dynamic balance are unsatisfactory and comprise no actual loss of balance while walking. Objectives: Using beam walking distance as a measure of dynamic balance, we will determine the psychometric properties, lifespan and patient reference values, the relationship with selected 'dynamic balance tests', and the accuracy of beam walking distance to predict falls. Methods: This cross-sectional observational study will examine healthy adults in 7 decades (n=432) at 4 centers. Center 5 will examine patients (n=100) diagnosed with Parkinson's disease, multiple sclerosis, stroke, and balance disorders. At Test 1, all participants will be measured for demographics, medical history, grip and leg strength, short physical performance battery, static balance on a force platform, and dynamic balance using beam walking (4m-long, 4, 8, and 12 cm wide) under single (beam walking only) and dual task conditions (beam walking while concurrently performing an arithmetic task). In addition, cognitive function (global cognition, attention, executive function, processing speed, memory) will be assessed. Patients and healthy participants age 50+ will be additionally measured for fear of falling, history of falls, miniBESTest, functional reach on a force platform, timed up and go, and reactive balance. At Test 2, 7-10 days after Test 1, healthy adults young and age 50+ (n=40) will be re-tested for reliability of beam walking performance. All participants age 50+ will be re-called to report fear of falling and fall history 6 and 12 months after Test 1. Conclusion: The investigators expect to find that beam walking performance vis-à-vis the traditionally used balance outcomes predicts more accurately fall risks and falls.
Most of patients with autoimmune encephalitis are left with permanent cognitive deficits of varying severity. The patients' life and career would be affected definitely by cognitive deficits. Recently, more and more clinical physician have begun to focus on cognitive impairment of patients with autoimmune encephalitis. Generally, the outcome was measured by the modified Rankin Scale (mRS). However, the mRS are commonly used to evaluate the degree of disability or dependence in the daily activities of the patients suffering from a stroke and cognition function were minimally evaluated in this scale. It is crucial to adopt detailed cognition tools to study the long-term cognitive outcomes and as an indicator of overall curative effect judgment in autoimmune encephalitis. Currently, only early immunotherapy is uniformly and consistently considered to produce favorable cognitive outcomes. However, studies concerning the association of second-line immunotherapy with cognitive outcomes have been scarce and have shown conflicting results regarding autoimmune encephalitis. Hence, the goal of this study was to explore cognitive neural mechanism of autoimmune encephalitis by using neuropsychological tests and multi-mode MRIs.
Pulmonary rehabilitation program with aerobic and strengthening for 3 months will be applied to the candidates for lung transplantation. The program will be designed to be 2 days supervised weekly and 3 day home program. Cognitive functions and exercise capacities of the patients before and after the program will be evaluated.
This study evaluates the application of non-invasive brain stimulation in the treatment of Mild Cognitive Impairment (MCI) in adults aged 55-85. Half of the participants will receive transcranial direct current stimulation (tDCS), while the other half will receive sham (like placebo) stimulation.
The aim of this study is to assess the brain correlates, as assessed with multimodal MRI, of working memory training in patients with severe traumatic brain injury (TBI)
Cognitive impairment is a significant health problem in the United States, resulting in costs over $100 billion a year. We will provide an efficient, effective, and financially intelligent solution to Primary Care Physician's to identify cognitive impairment in the earliest stages, delay progression through appropriate treatment, and to afford patients the opportunity to make future plans at a time when symptoms are mild and patients are able to make informed decisions concerning financial and life activities. This has the potential to delay devastating effects of cognitive impairment, and to lessen the financial burden on the health care system in the United States.
The purpose of this study is to investigate the efficacy of the Karie Automated Medication delivery device in enhancing medication adherence among a group of elderly patients with mild to moderate cognitive decline.
The study aims to use machine learning to predict the occurrence of episodic and autobiographical memory deficits as well as treatment response following a course of electroconvulsive therapy. Additionally, the neurophysiological correlates of the cognitive effects after a course of ECT will be investigated. Therefore, structural, resting-state and diffusion tensor images will be collected within one week before the first and after the last ECT treatment from severely depressed patients. Standard measures of cognitive function and specifically episodic as well as autobiographical memory will also be collected longitudinally and used for prediction. The study consists of 60 ECT receiving inpatients suffering from major unipolar or bipolar depression, 60 medication-only controls and 60 healthy controls.
The aim of this study is to investigate the effect of dual site-dual channel non-invasive brain stimulation for recovery of language and cognitive function in post stroke patients. Simultaneous dual site-dual channel stimulation was applied by using two sets of transcranial direct current stimulation devices. All subjects will go through four conditions of transcranial direct current stimulation with for 30 minutes. Four conditions are 1) Dual stimulation: i) anodal stimulation on ipsilesional inferior frontal cortex, ii) anodal stimulation on ipsilesional dorsolateral prefrontal cortex. 2) Single stimulation 1: anodal stimulation on ipsilesional inferior frontal cortex and cathodal stimulation on contralesional inferior frontal cortex; 3) Single stimulation 2: anodal stimulation on ipsilesional inferior frontal cortex and cathodal stimulation on contralesional supraorbital area.
