Purpose: A worldwide internet survey was conducted (1) to identify problems of individuals with traumatic brain injury (TBI) addressed by health professionals and (2) to summarize these problems using the International Classification of Functioning, Disability and Health (ICF). Method: A pool of professionals involved in the TBI rehabilitation process that included physicians, nurses, physical therapists, occupational therapists, social workers and psychologists were surveyed to identify problems in functioning and contextual factors of individuals with TBI using open-ended questions. All answers were translated ('linked') to the ICF based on established rules. The frequencies of the linked ICF categories were reported stratified based on context. Results: One-hundred thirty seven professionals from the six World Health Organization regions identified 5656 concepts. 92.66% could be linked to the ICF; 33.03% were related to the domain of body functions, 27.28% to activities and participation, 10.98% to structures and 21.38% to environmental factors. Conclusions: The complexity of TBI was described through the identification of a wide variety of ICF categories. ICF language proved to be a neutral framework allowing the comparison of answers between different professionals in different world regions. [ABSTRACT FROM AUTHOR]

Rehabilitation can improve cognitive deficits observed in patients with traumatic brain injury (TBI). However, despite rehabilitation, the ability of making a choice often remains impaired. Risk taking is a daily activity involving numerous cognitive processes subserved by a complex neural network. In this work we investigated risk taking using the Balloon Analogue Risk Task (BART) in patients with acute TBI and healthy controls. We hypothesized that individuals with TBI will take less risk at the BART as compared to healthy individuals. We also predicted that within the TBI group factors such as the number of days since the injury, severity of the injury, and sites of the lesion will play a role in risk taking as assessed with the BART. Main findings revealed that participants with TBI displayed abnormally cautious risk taking at the BART as compared to healthy subjects. Moreover, healthy individuals showed increased risk taking throughout the task which is in line with previous work. However, individuals with TBI did not show this increased risk taking during the task. We also investigated the influence of three patients’ characteristics on their performance at the BART: Number of days post injury, Severity of the head injury, and Status of the frontal lobe. Results indicate that performance at the BART was influenced by the number of days post injury and the status of the frontal lobe, but not by the severity of the head injury. Reported findings are encouraging for risk taking seems to naturally improve with time postinjury. They support the need of conducting longitudinal prospective studies to ultimately identify impaired and intact cognitive skills that should be trained postinjury.
