While motor and cognitive impairments are common in Multiple Sclerosis (MS) patients, research concerning their relationship in this population has been limited. We aimed to evaluate cross-sectional associations between cognitive functions, walking speed, and falls in patients with MS. Through a retrospective chart review of 81 patients with MS, we examined(More)
Multiple sclerosis (MS) is the most common cause of neurologic disease in young and middle-aged adults, and 75% of patients are female. Nearly one in two patients with MS will experience clinically significant depression-approximately three times the prevalence rate in the general population. This study used a cross-sectional approach to examine the link(More)
PRIMARY OBJECTIVE To determine if individuals with brain injury can modify heart rate variability (HRV) through biofeedback and, if so, enhance its pattern to improve emotional regulation and problem-solving ability. DESIGN A quasi-experimental design with repeated measures was employed. Thirteen individuals aged 23-63 years with severe brain injury(More)
Multiple sclerosis (MS) is frequently accompanied by changes in verbal memory. We hypothesized that administering an abbreviated California Verbal Learning Test-II (CVLT-II) would detect verbal memory problems in MS accurately, thus serving as a potential screening tool. We performed receiver-operating-characteristic (ROC) analyses of three trials (trial 1,(More)
OBJECTIVE Cognitive dysfunction is prevalent in multiple sclerosis. As self-reported cognitive functioning is unreliable, brief objective screening measures are needed. Utilizing widely used full-length neuropsychological tests, this study aimed to establish the criterion validity of highly abbreviated versions of the Brief Visuospatial Memory Test -(More)
BACKGROUND Cognitive impairments are common in individuals with MS and adversely affect functioning. Early detection of cognitive impairment, therefore, would enable earlier, and possibly more effective, treatment. We sought to compare self-reports with a short neuropsychological test as possible screening tools for cognitive impairment. METHODS One(More)
This paper presents a wireframe algorithm that helps visualize embedded Riemannian surfaces in R. Using information provided by the induced metric, also known as the first fundamental form defined in the Euclidean space, the algorithm aims to find an isometric embedding of the intrinsic surface in the three-dimensional space. The fundamental idea is to use(More)
