Randomized Controlled TrialCervicovestibular Rehabilitation in Adults with Mild Traumatic Brain Injury: A Randomised Clinical Trial.
The objective of this study was to compare the effects of a cervicovestibular rehabilitation program combined with symptom-limited aerobic exercise (SLAE) program to a SLAE program alone in adults with persistent symptoms after mild traumatic brain injury (mTBI) on severity of symptoms and other indicators of clinical recovery. In this single-blind, parallel-group randomized controlled trial, 60 adults with persistent symptoms after mTBI were randomly assigned to: (1) a 6-week SLAE program or (2) a 6-week cervicovestibular rehabilitation program combined with a SLAE program. All participants took part in four evaluation sessions (baseline, week 6, 12, and 26) performed by a blinded evaluator. ⋯ For PCSS, NPRS, NDI, HDI, DHI, and return to function, there were no group-by-time interactions at any time points follow-up (p > 0.05); clinically significant time effects were, however, observed (p < 0.05). There were group-by-time interactions at weeks 6 and 12 for vestibulo-ocular reflex (p < 0.003) and the craniovertebral mobility (p < 0.001) measures in favor of the cervicovestibular rehabilitation group. The study indicates that a cervicovestibular rehabilitation program combined with SLAE was not superior to a SLAE program alone in term of symptoms and functional level improvement but resulted in improved physical cervical and vestibular function.

Randomized Controlled TrialBrain Injury Effects on Neuronal Activation and Synaptic Transmission in the Basolateral Amygdala (BLA) of Adult Male and Female Wistar Rats.
Traumatic brain injury (TBI) is defined as brain damage produced by an external mechanical force that leads to behavioral, cognitive, and psychiatric sequelae. The basolateral amygdala (BLA) is involved in emotional regulation, and its function and morphology are altered following TBI. Little is known about potential sex-specific effects of TBI on BLA neuronal function, but it is critical for the field to identify potential sex differences in TBI effects on brain and behavior. ⋯ Further, TBI increased spontaneous excitatory and inhibitory postsynaptic current (sEPSC and sIPSC) amplitude in BLA neurons of females relative to all other groups. TBI increased sEPSC frequency in BLA neurons of females relative to males but did not alter sIPSC frequency. In summary, lateral fluid percussion produced different physiological responses in male and female rats, as well as sex-specific alterations in BLA neuronal activation, excitability, and synaptic transmission 1 h after injury.

Randomized Controlled Trial Multicenter StudyExercise improves cardiorespiratory fitness but not arterial health after spinal cord injury: The CHOICES trial.
Arterial stiffness, as measured by carotid-femoral pulse wave velocity (cfPWV), is elevated after spinal cord injury (SCI). In the uninjured population, exercise training has been shown to reduce arterial stiffness. In a randomized, multi-center clinical trial, we evaluated the impact of two exercise interventions on cardiovascular disease risk factors in persons with chronic SCI. ⋯ However, peak oxygen uptake increased with ACET compared with BWSTT (p = 0.04). The findings of this trial demonstrate that although 24 weeks of upper-body exercise improved CRF in persons with motor-complete SCI ≥T6, neither intervention resulted in improvements in arterial stiffness or cardiometabolic health measures. ClinicalTrials.gov identifier: NCT01718977.

Randomized Controlled Trial Multicenter StudyTargeting Autoregulation-Guided Cerebral Perfusion Pressure after Traumatic Brain Injury (COGiTATE): A Feasibility Randomized Controlled Clinical Trial.
Managing traumatic brain injury (TBI) patients with a cerebral perfusion pressure (CPP) near to the cerebral autoregulation (CA)-guided "optimal" CPP (CPPopt) value is associated with improved outcome and might be useful to individualize care, but has never been prospectively evaluated. This study evaluated the feasibility and safety of CA-guided CPP management in TBI patients requiring intracranial pressure monitoring and therapy (TBIicp patients). The CPPopt Guided Therapy: Assessment of Target Effectiveness (COGiTATE) parallel two-arm feasibility trial took place in four tertiary centers. ⋯ There were no significant differences between groups for TIL or for other safety end-points. Conclusively, targeting an individual and dynamic CA-guided CPP is feasible and safe in TBIicp patients. This encourages a prospective trial powered for clinical outcomes.

Randomized Controlled TrialCarbamazepine for Irritability and Aggression after Traumatic Brain Injury: A Randomized, Placebo-Controlled Study.
This study tested the hypothesis that carbamazepine (CBZ) reduces irritability/aggression among individuals >6 months post-traumatic brain injury (TBI). Seventy individuals were enrolled in a parallel-group, randomized, double-blind, placebo-controlled, forced-titration trial of CBZ (n = 35) versus placebo (n = 35). Participants were randomly assigned to receive CBZ or placebo 42 days with outcome assessed at baseline and Day 42. ⋯ Large placebo effects may have masked the detection of differences. Clinician rating metrics suggest benefit, and thus, CBZ should remain a treatment option for the experienced brain injury clinician. Data are provided that may aid treatment decisions.
