This study aimed to (1) identify the prevalence and severity of pain and psychiatric comorbidities among personnel who had been deployed during Operation Iraqi Freedom (OIF), Operation Enduring Freedom (OEF), and Operation New Dawn (OND) and (2) assess whether the Department of Veterans Affairs (VA) Polytrauma System of Care and an OIF/OEF/OND registry reflect real differences among patients. Participants (N = 359) were recruited from two VA hospitals. They completed a clinical interview, structured diagnostic interview, and self-report measures. Results indicated pain was the most common complaint, with 87 percent experiencing pain during the prior week and 56 percent reporting moderate or severe pain. Eighty percent of participants met criteria for at least one of seven assessed comorbid problems (moderate or severe pain, postconcussional disorder, posttraumatic stress disorder [PTSD], anxiety disorder, mood disorder, substance use disorder, psychosis), and 59 percent met criteria for two or more problems. PTSD and postconcussional disorder rarely occurred in the absence of pain or other comorbidities (0.3% and 0%, respectively). The Polytrauma group had more comorbid psychiatric conditions (χ(2) = 48.67, p < 0.05) and reported greater severity of symptoms (p < 0.05) than the Registry group. This study confirmed the high prevalence of pain and concurrent mental health problems among personnel returning from military deployment.

Work plays a significant role in how people identify themselves, and successful return to work is associated with significant psychological and rehabilitative benefits. Unfortunately, despite the many benefits of employment, Veterans who experience mild traumatic brain injury and have mental health issues often have significant difficulty getting their vocational needs met. Considering that a consistent relationship between cognitive dysfunction and difficulties with employability has been firmly established, cognitive rehabilitation may enhance engagement in vocational rehabilitation and return to work outcomes. In this pilot study, we evaluated a 12 wk cognitive rehabilitation intervention embedded within vocational rehabilitation services. Eighteen Veterans were randomly assigned to receive either the embedded cognitive rehabilitation intervention (n = 10) or a control condition offering supportive client-centered therapy that did not focus on employment or cognitive rehabilitation (n = 8); all Veterans (intervention and control groups) received vocational rehabilitation services. This pilot feasibility study demonstrated efficient implementation of an embedded cognitive rehabilitation intervention within vocational rehabilitation. The current pilot data revealed small to moderate effect sizes on employment outcomes. Given these preliminary findings, a larger outcome study is warranted.

This study compared health status across four trauma/posttraumatic stress disorder (PTSD) groups of older adults with depression, anxiety, and/or at-risk drinking who attended primary care appointments (N = 1,199; mean age = 73.5 yr), mostly at Department of Veterans Affairs hospitals. The trauma and PTSD categories were PTSD (n = 81), partial PTSD (n = 127), trauma only (n = 323), and no trauma (n = 668). Physical and mental health-related quality of life (HQL), indices of social and economic impairment and stigma regarding treatment-seeking were compared among groups. Group differences were found for several indicators of functional impairment; the PTSD group had fewer close friends and higher treatment-seeking stigma beliefs related to having a disorder. Linear mixed modeling examined associations between trauma/PTSD group and HQL. After accounting for covariates, the trauma/PTSD groups differed across the Medical Outcome Study Short Form-36 scales and component scores (indicated by significant group by scale interaction). Differences among groups were confined to mental health measures; those with PTSD had worse HQL. Post hoc analyses examined the number of comorbid psychiatric diagnoses by trauma/PTSD group. Overall, findings indicate that mental HQL varies among older adults with trauma and PTSD and that although treatment-related stigma does not differ among groups, it does affect HQL.

Female Veterans are the most rapidly growing segment of new users of the Veterans Health Administration (VHA), and a significant proportion of female Veterans receiving treatment from VHA primary care providers report persistent pain symptoms. Currently, available data characterizing the neurobiological underpinnings of pain disorders are limited. Preclinical data suggest that neurosteroids may be involved in the modulation of pain symptoms, potentially via actions at gamma-aminobutyric acid (GABA) and N-methyl-D-aspartate (NMDA) receptors. Dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) are neurosteroids that modulate inhibitory GABA receptors and excitatory NMDA receptors, producing complex neuronal effects. Emerging evidence from male Iraq/Afghanistan-era Veterans suggests that reductions in neurosteroid levels are associated with increased pain symptoms and that neurosteroids may be promising biomarker candidates. The current exploratory study thus examined associations between self-reported pain symptoms in 403 female Iraq/Afghanistan-era Veterans and serum DHEAS and DHEA levels. Serum DHEAS levels were inversely correlated with low back pain in female Veterans (Spearman r = -0.103; p = 0.04). Nonparametric analyses indicate that female Veterans reporting moderate/extreme low back pain demonstrated significantly lower DHEAS levels than those reporting no/little low back pain (|Z| = 2.60; p = 0.009). These preliminary findings support a role for DHEAS in pain physiology of low back pain and the rationale for neurosteroid therapeutics in pain analgesia.

Energy storage and return (ESR) feet have long been assumed to promote metabolically efficient amputee gait. However, despite being prescribed for approximately 30 yr, there is limited evidence that they achieve this desired function. Here, we report a meta-analysis of data from 10 studies that met our selection criteria to determine whether amputee walking with ESR feet is more efficient than with conventional solid ankle cushioned heel (SACH) feet. Additionally, the data were tested for a relationship with walking speed since it has been suggested ESR feet might perform better at higher speeds. The raw data are highly variable because of differences in study protocols; therefore, we normalized the data and found a statistically significant difference (p < 0.001) between ESR and SACH feet. However, the magnitude of this difference is small, with the cost of transport (COT) with ESR feet being 97.3% of the cost with SACH feet. No relationship between ESR COT and speed was found (p = 0.19). We hypothesize that the small but statistically significant difference between ESR and SACH feet may not constitute a functionally significant improvement in COT, possibly related to the limited push-off power provided by ESR feed compared with nondisabled ankles.

Dynamic arm supports are provided to assist with activities of daily living (ADLs) in people with limited upper-limb function. However, the perceived functional benefit of these devices in daily life is unknown. Insight into the functional benefit may give direction to the development of new devices and may affect the factors that patients and their health care providers consider during the selection process of a device. A cross-sectional study involving 23 Dutch experienced dynamic arm support users was performed in the Netherlands. The study included a questionnaire, an interview, and an observation of ADL task performance in the domestic setting. Twenty participants completed this study. Five users had a large perceived functional benefit, nine a moderate benefit, and five no benefit (one was unable to indicate the benefit). People with limited functional abilities benefited most. Participants varied in the amount of device use, activities the device is used for, and reasons for using (or not using) the device. On an individual level, selection using a selection tool and a good evaluation of the prescription could improve user-device matches.
