NeuroRehabilitation

Because traumatic brain injury affects between 1.5 and 2 million individuals per year and results in long term vocational and financial difficulties, there is growing interest in determining those factors that predict successful outcomes for specific groups of individuals with TBI. An NIH consensus panel on TBI has suggested that women are one group that needs more attention, particularly given the studies indicating that men and women experience different cognitive [14], emotional [19], and vocational outcomes following TBI [5]. The current study evaluated differences in injury severity, demographics, neuropsychological abilities, and vocational and financial outcomes for 78 persons with TBI (55 male, 23 female) who received services from a state Vocational Rehabilitation Division (DVR). Despite similar injury severity, neuropsychological and demographic characteristics, more men (43.6%) received Maintenance services from MO-DVR than women (21.7%). Of note, only 4.4% of the women were successfully employed through DVR, compared to 23.6% of the men. In addition, 73.9% of the women had services terminated after being accepted by DVR but before services were initiated, compared to 56.4% of the men. The significance of these results is discussed, as are the limitations of the current project.

The use of typical neuroleptics has always been the mainstay of treatment for delirium following traumatic brain injury (TBI). Given the recent application of atypical neuroleptics to various psychiatric conditions formerly treated with typical neuroleptics, one questions whether this new class of drugs is superior to its predecessor in treating delirium post-TBI. We present a case of one patient with TBI-induced delirium where in fact the use of the typical mid-potency neuroleptic, loxapine, appeared to have a better clinical effect over the atypical neuroleptic, olanzapine.

Parkinson's disease (PD) is a neurodegenerative disorder with progressive impairment in motor and cognitive functioning. A review of past research shows that individuals experience not only physical discomfort brought on by the illness, but also considerable psychological distress. Increased dependency on a caregiver due to impairments in activities of daily living (e.g., walking, eating, dressing) may bring on feelings of being a burden and strain relationships. However, since PD is a chronic illness, it necessitates family caregiving throughout the life-span. This has implications for the family members who need to redefine their roles within the family to manage the circumstances brought on by the illness. Such strains may include finances, threats to employment, social isolation or health strain. Thus, it becomes imperative to provide unrelenting support to the affected family and individual, to enable them to refocus and learn to manage new illness-related, task-oriented, and affective roles. This enhances the integrity and self-esteem of the patient and helps the family's adjustment to illness of a member. This paper outlines, the role of mental health professionals in providing counseling and psychoeducational approaches to helping patients and their families.

Cortical visual disturbances can occur after traumatic or ischemic brain lesion. Patients mostly suffer from hemianopia. Different treatment approaches in patients with hemianopia are being debated with respect to their effectiveness. For more severely disabled patients with cortical blindness or residual rudimentary vision (RRV) no systematic therapeutic approaches have been reported. In a case study the positive effects of a recently developed repetitive photic stimulation therapy in a patient with RRV after a bioccipital ischemic infarction are presented. The application of this new therapy over several months, supported by treatment with amphetamines led to a statistically significant improvement of different visual functions and a reoccurrence of visual abilities important in daily life. The pathophysiological basis and possible neurorehabilitative consequences that arise from these results are discussed with respect to similar findings in animal experiments.

The traditional disease and diagnostic medical model is not always useful to brain injury professionals who need to describe, measure, and compare deficits associated with neurologic insult. Professionals in neurorehabilitation are in need of new systems that will assist them in identifying impairments and areas of intervention. The aim of this article is to present the International Classification of Functioning, Disability and Health (ICF), and its applications to brain injury rehabilitation. This taxonomy, developed by the WHO, allows the classification and assessment of functioning and disability in everyday activities and social involvement for individuals with medical conditions. Multi-disciplinary teams from 65 countries have collaborated in the development of the ICF to develop a tool that serves different purposes and disciplines with high trans-cultural validity. It can be of great value for professionals working in the field of brain injury who need to describe and quantify in detail neurocognitive, emotional, and sensory-motor functions as well as their impact on activities and participation in life situations. Its applications also extend to the domains of epidemiology, public health and public policy.

In this paper we present a mechanical apparatus and methods named BalanceReTrainer for standing-balance training in neurologically impaired individuals. BalanceReTrainer provides an impaired individual with a fall-safe balancing environment, where the balancing efforts of a standing individual are augmented by stabilizing forces acting at the level of pelvis in the sagittal and frontal planes of motion, assisting the balancing activity ankle and hip muscles and at the level of shanks, assisting the knee extensor muscles. A range of different levels of supporting forces is generated by passive, compliant means. Additionally, movement in the sagittal and frontal planes, acquired by transducers is fed to an electronic interface which transforms the current inclinations into a computer mouse signals, which are interfaced to a personal computer (PC) where balance training and evaluation program is running. The level of stiffness support and level of difficulty of computer task can be selected according to current balancing abilities of the impaired individual. We further present results of a case study where an ambulatory chronic hemiparetic subject with neglect syndrome received ten days of balance training on BalanceReTrainer. Biomechanical evaluation of weight-shifting activity before and after treatment shows a substantial functional improvement.
