Randomized Controlled TrialAcupuncture Treatment for Chronic Post-traumatic Headache in Individuals with Mild Traumatic Brain Injury: A Pilot Study.
Chronic post-traumatic headache (CPTH) after a mild traumatic brain injury (mTBI) has been reported in up to 60% of patients and can be extremely debilitating. While pharmacological treatments are typically used for CPTH, they frequently cause side effects and have limited effectiveness, leading individuals with CPTH to be unsatisfied with current treatment options and to seek nonpharmacological options. Acupuncture has been identified as a potential treatment option; however, the evidence in this population remains limited. ⋯ There were no significant changes in acute medication use or sleep quality. While there were some QOL improvements identified, these results should be interpreted with caution. Overall, acupuncture was shown to be safe and well-tolerated in people with CPTH after mTBI, and five acupuncture treatments using a standardized protocol shows promise in providing headache relief for this population.

Randomized Controlled TrialGoal-Oriented Attentional Self-Regulation Training in Chronic Mild Traumatic Brain Injury is Linked to Microstructural Plasticity in Prefrontal White Matter.
Impaired attention is one of the most common, debilitating, and persistent consequences of traumatic brain injury (TBI), which impacts overall cognitive and executive functions in these patients. Previous neuroimaging studies, trying to understand the neural mechanism underlying attention impairment post TBI, have highlighted the role of prefrontal white matter tracts in attentional functioning in mild TBI (mTBI). Goal-Oriented Attentional Self-Regulation (GOALS) is a cognitive rehabilitation training program that targets executive control functions in participants by applying mindfulness-based attention regulation and goal management strategies. ⋯ Our results show significantly better white matter microstructural integrity in left and right anterior corona radiata (ACR) in the GOALS group compared with the control group post-training. Moreover, we found a significant correlation between sustained attention ability of GOALS training participants and white matter integrity of their right ACR pre- and post-training. Finally, our findings indicated that the improved white matter integrity of the ACR in GOALS training participants was the result of increased neurite density and decreased fiber orientation dispersion within this tract.

Randomized Controlled Trial Multicenter StudyPredicting Progression of Intracranial Hemorrhage in the Prehospital TXA for TBI Trial.
Progression of intracranial hemorrhage is a common, potentially devastating complication after moderate/severe traumatic brain injury (TBI). Clinicians have few tools to predict which patients with traumatic intracranial hemorrhage on their initial head computed tomography (hCT) scan will progress. The objective of this investigation was to identify clinical, imaging, and/or protein biomarkers associated with progression of intracranial hemorrhage (PICH) after moderate/severe TBI and to create an accurate predictive model of PICH based on clinical features available at presentation. ⋯ Models composed of machine-selected features performed better than models composed of expert-selected variables (reaching an average of 77% accuracy, AUC = 0.78 versus AUC = 0.68 for the expert-selected variables). Predictive models utilizing variables measured at admission can accurately predict PICH, confirmed by the 6-hour follow-up hCT. Our best-performing models must now be externally validated in a separate cohort of TBI patients with low GCS and initial hCT positive for hemorrhage.

Randomized Controlled TrialExoskeletal-Assisted Walking during Acute Inpatient Rehabilitation Enhances Recovery for Persons with Spinal Cord Injury - A Pilot Randomized Controlled Trial.
Spinal cord injury (SCI) negatively impacts individuals' functional independence, and motor and sensory function. Intense walking training has been shown to facilitate recovery for individuals with chronic SCI. Powered robotic exoskeletons provide therapists with a tool that allows them to conduct walking training with less therapist effort as compared to conventional walking training. ⋯ Incorporating EAW into AIR may facilitate functional, motor, and sensory recovery for individuals with SCI during AIR better than standard AIR. However, the study had a limited sample size. Further studies are needed to clarify the effects of EAW in AIR.

Randomized Controlled TrialCardiorespiratory Responses to Acute Intermittent Hypoxia in Humans with Chronic Spinal Cord Injury.
Brief exposure to repeated episodes of low inspired oxygen, or acute intermittent hypoxia (AIH), is a promising therapeutic modality to improve motor function after chronic, incomplete spinal cord injury (SCI). Although therapeutic AIH is under extensive investigation in persons with SCI, limited data are available concerning cardiorespiratory responses during and after AIH exposure despite implications for AIH safety and tolerability. Thus, we recorded immediate (during treatment) and enduring (up to 30 min post-treatment) cardiorespiratory responses to AIH in 19 participants with chronic SCI (>1 year post-injury; injury levels C1 to T6; American Spinal Injury Association Impairment Scale A to D; mean age = 33.8 ± 14.1 years; 18 males). ⋯ All participants completed AIH treatment without difficulty. No significant changes in ventilation, heart rate, or arterial blood pressure were found 30 min post-AIH p > 0.05). In conclusion, therapeutic AIH is well tolerated, elicits variable chemoreflex activation, and does not cause persistent changes in cardiorespiratory control/function 30 min post-treatment in persons with chronic SCI.
