ReviewElectronic assistive technology to support memory function after traumatic brain injury: A systematic review of efficacy and user perspectives.
Abstract Rapid technology advances have led to diverse assistive technology (AT) options for use in memory rehabilitation after traumatic brain injury (TBI). This systematic review aimed to evaluate the efficacy of electronic AT for supporting phases of memory in daily life after TBI. A secondary aim was to examine user perspectives on the utility of AT and factors influencing uptake or use. ⋯ There was the most empirical support for the efficacy of AT for facilitating retrieval and execution phases of memory (i.e., supported by 6/9 studies) with external support to encode memory intentions or pre-programmed reminders. Further controlled studies are needed to determine whether outcomes vary according to individuals' level of independence with use (e.g., self-initiated vs. pre-programmed reminders) and to examine user characteristics and design features influencing uptake and effectiveness. Greater involvement of end-users with brain injury in the design and evaluation of AT features is also recommended to enhance usability and uptake in daily life.

Multicenter StudyEarly Signs of Elevated Intracranial Pressure (ICP) on Computed Tomography Correlate with Measured ICP in the Intensive Care Unit and Six-Month Outcome Following Moderate to Severe TBI.
Traumatic brain injury (TBI) is a leading cause of death and disability in the United States. Early triage and treatment after TBI have been shown to improve outcome. Identifying patients at risk for increased intracranial pressure (ICP) via baseline computed tomography (CT) , however, has not been validated previously in a prospective dataset. ⋯ Sulcal obliteration and third ventricular compression, radiographic signs of elevated ICP, were significantly associated with measurements of ICP ≥20 mm Hg. These radiographic biomarkers were significantly associated with patient outcome. There is potential utility of ICP-related imaging variables in triage and prognostication for patients after moderate-severe TBI.

An at-home, virtually administered graded exertion protocol for use in concussion management: Preliminary evaluation of safety and feasibility in healthy youth and children with subacute concussion.
Graded exertion testing (GXT) is an important tool for concussion management, as it is used to personalize post-concussion exercise prescription and return athletes to sport. However, most GXT requires expensive equipment and in-person supervision. Our objective was to assess the safety and feasibility of the Montreal Virtual Exertion (MOVE) protocol, a no-equipment, virtually compatible GXT, in healthy children and children with subacute concussion. ⋯ Among concussed youth, increases in heart rate (MOVE: 82.4 ± 17.9 bpm, BCTT: 72.1 ± 23.0 bpm; t(28) = 1.36, p = 0.18), RPE (MOVE: 5.87 ± 1.92, BCTT: 5.07 ± 2.34, t(28) = 1.02, p = 0.32), and overall symptom presentation were similar between the MOVE and BCTT protocols. The MOVE protocol is a safe and feasible GXT in healthy youth and youth with subacute concussion. Future studies should assess the fully virtual administration of the MOVE in children with concussion, MOVE protocol tolerability in children with acute concussion, and whether the MOVE protocol can be used to guide individualized exercise prescription.

Prognostication and Withdrawal of Care Decisions in Severe Traumatic Brain Injury: A Survey of The Seattle International Severe Traumatic Brain Injury Consensus Conference (SIBICC) Working Group.
Abstract Best practice guidelines have advanced severe traumatic brain injury (TBI) care; however, there is little that currently informs goals of care decisions and processes despite their importance and frequency. Panelists from the Seattle International severe traumatic Brain Injury Consensus Conference (SIBICC) participated in a survey consisting of 24 questions. Questions queried use of prognostic calculators, variability in and responsibility for goals of care decisions, and acceptability of neurological outcomes, as well as putative means of improving decisions that might limit care. ⋯ Whether conceptualizing an ideal or existing prognostic calculator to predict death or an unacceptable outcome, on average a 64-69% chance of a poor outcome was felt to justify treatment withdrawal. These results demonstrate important variability in goals of care decision making and a desire to reduce this variability. Our panel of recognized TBI experts opined on the neurological outcomes and chances of those outcomes that might prompt consideration of care withdrawal; however, imprecision of prognostication and existing prognostication tools is a significant impediment to standardizing the approach to care-limiting decisions.

Adolescents with More Oculomotor and Vestibular Signs of Sport-Related Concussion Benefit from Aerobic Exercise: an Exploratory Analysis.
Abstract Early targeted heart rate (HR) aerobic exercise has been shown to reduce the duration of recovery from sport-related concussion (SRC) as well as the incidence of persistent post-concussive symptoms (PPCS). It is not known, however, if more severe oculomotor and vestibular presentations of SRC benefit from a prescription of aerobic exercise. The current study is an exploratory analysis of two published randomized controlled trials that compared aerobic exercise within 10 days of injury with a placebo-like stretching intervention. ⋯ Aerobic exercise (hazard ratio = 0.621 [0.412, 0.936], p = 0.023) reduced recovery times even when controlling for site (hazard ratio = 0.461 [0.303, 0.701], p < 0.001), severity (hazard ratio = 0.528 [0.325, 0.858], p = 0.010) and the interaction term of intervention and severity (hazard ratio = 0.972 [0.495, 1.909], p = 0.935). Adolescents who presented with >3 signs and were assigned to the placebo-like stretching group had a PPCS incidence of 38%, which was the highest of all subgroups (aerobic exercise and ≤3 findings: 8%; stretching and ≤3 findings: 11%; aerobic exercise and >3 findings: 21%). This exploratory study provides pilot evidence that prescribed sub-symptom threshold aerobic exercise treatment early after SRC may be effective for adolescents with more oculomotor and vestibular physical examination signs and should be validated in future adequately powered trials.
