Postural Assessment

Abstract Context: Postural control and cognitive function are adversely affected by acute mild traumatic brain injury (mTBI). Whether postural-control deficits persist beyond the acute stage in individuals with a history of mTBI is unclear. Objective: To determine if postural-control deficits persist in individuals with a history of mTBI. Design: Retrospective cross-sectional study. Setting: University research laboratory. Patients or Other Participants: As part of an ongoing investigation examining cognitive and motor deficits associated with mTBI, 224 individuals participated in the study. Of these, 62 participants self-reported at least 1 previous physician-diagnosed mTBI. Intervention(s): Postural control was assessed using the NeuroCom Sensory Organization Test (SOT) postural-assessment battery. Main Outcome Measure(s): The SOT postural assessment yields 4 indices of postural control: a composite balance score, a visual ratio score, a somatosensory score, and a vestibular score. Postural dynamics were also examined by calculating approximate entropy of center-of-pressure excursions in the anteroposterior and mediolateral axis for each test condition. Results: Minimal differences in the SOT indices were noted among individuals with and without a history of previous mTBI (P > .05). In the group with a history of mTBI, anteroposterior postural irregularity decreased as postural difficulty increased. In contrast, the group without a history of mTBI displayed increased postural irregularity in the mediolateral direction. Conclusions: Individuals with a history of mTBI exhibited altered postural dynamics compared with individuals without a history of mTBI. These findings support the notion that changes in cerebral functioning that affect postural control may persist long after acute injury resolution.

Symptom Attribution

Abstract Objective The purpose of this study was to examine rates of “post-concussive” symptom endorsement and symptom attribution in Veterans with a history of mild traumatic brain injury (mTBI). We also explored the relationship between symptom endorsement and symptom attribution and assessed correlates of each. Method This cross-sectional study included 48 combat-exposed Iraq/Afghanistan Veterans with remote history of mTBI. All Veterans completed clinical interviews and self-report questionnaires assessing sociodemographic factors, injury and combat-related variables, psychiatric distress, self-efficacy, and coping style. To assess symptom endorsement and symptom attribution, a modified version of the Neurobehavioral Symptom Inventory was administered. Results Results showed that the most commonly endorsed “post-concussive” symptoms were several non-specific symptoms, and the symptoms most frequently attributed to mTBI included forgetfulness, poor concentration, and headaches. Furthermore, although there were some overlapping correlates of both symptom endorsement and symptom attribution, unique variables were associated with each domain. Specifically, symptom endorsement was uniquely associated with measures of psychiatric distress, while symptom attribution was uniquely associated with having a history of loss of consciousness and a greater degree of combat exposure. Conclusions Taken together, results suggest that endorsement of symptoms may be significantly impacted by the presence of mental health comorbidities, but that perceptions or beliefs as to why symptoms are occurring are related more to mTBI and combat-related characteristics. Findings offer potential avenues for therapeutic intervention, emphasize the importance of psychoeducation, and highlight the need to consider using alternate terminology for these symptoms that promotes recovery and minimizes misattribution of symptoms.

Mild traumatic brain injury, mTBI, is a leading cause of disability worldwide, with acute pain manifesting as one of its most debilitating symptoms. Understanding acute post-injury pain is important since it is a strong predictor of long-term outcomes. In this study, we imaged the brains of 172 patients with mTBI, following a motorized vehicle collision and used a machine learning approach to extract white matter structural and resting state fMRI functional connectivity measures to predict acute pain. Stronger white matter tracts within the sensorimotor, thalamic-cortical, and default-mode systems predicted 20% of the variance in pain severity within 72 hours of the injury. This result generalized in two independent groups: 39 mTBI patients and 13 mTBI patients without whiplash symptoms. White matter measures collected at 6-months after the collision still predicted mTBI pain at that timepoint (n = 36). These white-matter connections were associated with two nociceptive psychophysical outcomes tested at a remote body site – namely conditioned pain modulation and magnitude of suprathreshold pain–, and with pain sensitivity questionnaire scores. Our validated findings demonstrate a stable white-matter network, the properties of which determine a significant amount of pain experienced after acute injury, pinpointing a circuitry engaged in the transformation and amplification of nociceptive inputs to pain perception.

Abstract Objective Examine factors associated with history of arrests and felony incarceration among Veterans and Service Members (V/SM) with combat exposure. Method Participants were V/SM who completed a baseline assessment for the multicenter Chronic Effects of Neurotrauma Consortium study (N = 1555). Most were male (87%), white (72%), with a mean age of 40 years (SD = 9.71). The majority (83%) reported a history of ≥1 mild traumatic brain injury (mTBI), with thirty-five present of those experiencing 3+ mTBIs. Results Three groups were composed based on self-reported level of involvement with the criminal justice system: 1.) No history of arrests or incarcerations (65%), 2.) A lifetime history of arrest but no felony incarceration (32%), and 3.) A lifetime history of felony incarceration (3%). Chi-square and Kruskal-Wallis H tests revealed statistically significant differences between the groups in demographic factors including the incarcerated group having younger age, greater percentage of men, lower education, and greater percentage of never being married, followed by the arrest group and then the no arrest group (all p < 0.05). The incarcerated group also had the highest level of posttraumatic stress disorder (PTSD) symptoms, lowest social support, and greatest percentage of hazardous alcohol consumption, followed by the arrest and then the no arrest groups (all p < 0.05). No differences were found between groups for mTBI history or neuropsychological testing results. Conclusions Correlates of legal involvement among V/SM span demographic and psychological dimensions. Some correlates are modifiable, including social support, PTSD symptoms, and alcohol consumption. Addressing these modifiable risk factors is critical to lower the risk of future criminal justice involvement.

Abstract Patient reported history of comorbid illness may be the only information available to the treatment team during an acute injury admission. Nevertheless, acute injury, particularly traumatic brain injury (TBI) which affects cognition, may decrease the patient’s ability to accurately report medical history. Thus, the objective of this study was to evaluate the accuracy of patient-reported comorbid illness burden compared to the patient’s Medicare administrative claims. Records of older adults treated for TBI at an urban level 1 trauma center 2006-2010 were linked to their Medicare administrative. Comorbidities were recorded in Medicare claims based on ICD9 codes and were reported in the trauma registry (TR) based on patient medical history recorded by a physician or nurse. Prevalence of each of the following comorbidities was calculated using information from the TR and claims: Alzheimer’s disease and related dementias, chronic kidney disease, COPD, heart failure, diabetes, depression, stroke, and hypertension. Sensitivity of each patient-reported comorbidity was calculated using Medicare claims as the gold standard. We identified patient factors associated with accurate self-report using logistic regression. Among 408 older adults with TBI that linked to their Medicare claims, prevalence of each comorbidity was higher in Medicare claims compared to the TR, except for hypertension. Sensitivity for detecting these comorbidities using the TR ranged from 2% to 68%, with the highest sensitivity observed for hypertension. Older age and race were predictors of less accurate reported medical history. Reconciling self-reported patient history of these comorbidities with those reported in claims can better inform decisions regarding treatment.
