Statistical analysis of categorical data often relies on multiway contingency tables; yet, as the number of categories and/or variables increases, the number of table cells with few (or zero) observations also increases. Unfortunately, sparse contingency tables invalidate the use of standard goodness-of-fit statistics. Limited-information fit…

Purpose: The goal of this study was to establish the perceptual underpinnings of the terms that are commonly used by patients when describing the quality of their tinnitus. Method: Using a free-classification method, 15 subjects with normal hearing placed 60 different tinnitus-like sounds into similarity clusters on a grid. Multidimensional…

In the present work, we have undertaken a proof-of-concept study to determine whether a simple upper-limb movement could be useful to accurately classify low-functioning children with autism spectrum disorder (ASD) aged 2-4. To answer this question, we developed a supervised machine-learning method to correctly discriminate 15 preschool children…

A significant percentage of patients suffering from a stroke involving motor-relevant central nervous system regions will develop a spastic movement disorder. Hyperactivity of different muscle combinations forces the limbs affected into abnormal postures or movement patterns. As muscular hyperactivity can effectively and safely be treated with…

The aim of our study was to develop a graphical tool that can be used in addition to standard statistical criteria to support decisions on the number of classes in explorative categorical latent variable modeling for rehabilitation research. Data from two rehabilitation research projects were used. In the first study, a latent profile analysis was…

Hemicrania continua is an uncommon primary headache disorder, characterized by continuous unilateral pain, where pain exacerbations are associated with cranial autonomic features. The hallmark of this condition is the absolute response to indometacin. We describe the phenotype of this condition in a large series of patients. Thirty-six (92%)…

Introduction: Annually, over 3,000 rural veterans are admitted to Veterans Health Administration (VA) hospitals for acute myocardial infarction (AMI), yet no studies of AMI have utilized the VA rural definition. Methods: This retrospective cohort study identified 15,870 patients admitted for AMI to all VA hospitals. Rural residence was identified…

Aim: This study investigated the reliability and validity of the Barry-Albright Dystonia Scale (BADS), the Burke-Fahn-Marsden Movement Scale (BFMMS), and the Unified Dystonia Rating Scale (UDRS) in patients with bilateral dystonic cerebral palsy (CP). Method: Three raters independently scored videotapes of 10 patients (five males, five females;…

Systematic Treatment Selection (STS) is a form of technical eclectism that develops and plans treatments using empirically founded principles of psychotherapy. It is a model that provides systematic guidelines for the utilization of different psychotherapeutic strategies based on patient qualities and problem characteristics. Historically, it…

The objective of this study was development and psychometric testing of an adaptive, International Classification of Functioning, Disability, and Health (ICF)-oriented questionnaire to be processed by the rehabilitation physician that aids in assessing mobility, self-care, and domestic life (Moses-Physician). The intent is to develop a physician…

A sample of chronic postconcussive patients with and without overt malingering signs was compared with objectively brain-injured patients (total sample=106) on common episodic memory and malingered amnesia measures. Findings validate commonly cited malingering measures and new methods of classifying malingering in real-world clinical samples. (SLD)

The usefulness of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and the Personality Assessment Inventory (PAI) in the classification of patients diagnosed with Borderline Personality Disorder (BPD) was investigated. Twenty-two female inpatients diagnosed as having BPD and 22 female student control participants participated in the…

Describes methods used in a project at George Washington University's Rehabilitation Research and Training Center to predict and classify a family's involvement in a patient's rehabilitation program. As family attitudes can enhance or damage a program's effectiveness, early identification of uncooperative families is necessary so that intervention…
