Study Design. Retrospective Objective. To predict satisfaction with medical rehabilitation. Summary of Background Data. While spinal cord injury (SCI) patient satisfaction with life and community services has been investigated, satisfaction with medical rehabilitation has not. Methods. Information submitted to the Uniform Data System for Medical Rehabilitation ( 1998 - 2001) by 134 hospitals/rehabilitation facilities in the United States (n = 6,205 patients with SCI) was examined. Predictors were sociodemographic variables, Case Mix Groupings (CMG) ( 401 - 505, 5001), length of stay, rehospitalization, followup therapy, and health maintenance. Satisfaction was assessed at a mean of 92.2 days (SD 11.9 days) postdischarge. Data were analyzed according to who reported the outcome ( patient, n = 3,858 or family/other, n = 1,869). Statistical modeling was conducted using logistic regression. Results. High overall satisfaction was reported (94%). Significant predictors for the patient report data were CMG and rehospitalization. Compared with CMG 5001 ( short stay,

Computer technology can overcome mobility and functional limitations resulting from spinal cord injury (SCI) and enable re-employment. This study aimed to identify barriers and supports to effective technology use at work from the unique perspectives of technology users themselves. A qualitative research design was used to explore the perspectives of 11 technology users with SCI. In-depth, open-ended interviews and observations were conducted at each person’s workplace. Five major themes emerged: identifying the best or right technology; acquiring the technology; customizing and learning to use the technology; supporting the technology; and empowerment. Understanding these consumer perspectives enables professionals to empower people with SCI to optimize their work potential.

By most accounts the psychological stressor restraint produces a distinct pattern of neuronal activation in the brain. However, some evidence is incongruous with this pattern, leading us to propose that the restraint- induced pattern in the central nervous system might depend on the duration of restraint used. We therefore determined the pattern of neuronal activation ( as indicated by the presence of Fos protein) seen in the paraventricular nucleus (PVN), bed nucleus of the stria terminalis, amygdala, locus coeruleus, nucleus tractus solitarius (NTS), ventrolateral medulla (VLM) and thoracic spinal cord of the rat in response to 0, 15, 30 or 60 min periods of restraint. We found that although a number of cell groups displayed a linear increase in activity with increasing durations of restraint ( e. g. hypothalamic corticotrophin-releasing factor (CRF) cells, medial amygdala neurons and sympathetic preganglionic neurons of the thoracic spinal cord), a number of cell groups did not. For example, in the central amygdala restraint produced both a decrease in CRF cell activity and an increase in non-CRF cell activity. In the locus coeruleus, noradrenergic neurons did not display Fos in response to 15 min of restraint, but were significantly activated by 30 or 60 min restraint. After 30 or 60 min restraint a greater degree of activation of more rostral A1 noradrenergic neurons was observed compared with the pattern of A1 noradrenergic neurons in response to 15 min restraint. The results of this study demonstrate that restraint stress duration determines the amount and the pattern of neuronal activation seen in response to this psychological stressor.

The present study examined 24 individuals with either complete or incomplete injuries to the cervical spinal cord through the use of standardized assessments of dysarthria and a perceptual rating scale. Perceptual assessment revealed predominantly prosodic and phonatory disturbances, while physical impairments were common in the respiratory and laryngeal subsystems of speech production. A reduction in intelligibility and speaking rate resulted in a diminished communicative effectiveness ratio for most participants. Individuals showed a high degree of variation, with no clear relationship between lesion type and impairments present. Further investigation is required to verify the physiological nature of the respiratory and laryngeal impairments found in the present investigation and to determine the relative contributions of these to the overall presentation of speech and voice post cervical spinal cord injury (CSI).
