Testing the role of aerobic exercise in the treatment of posttraumatic stress disorder (PTSD) symptoms in U.S. active duty military personnel: a pilot study.

The purpose of this pilot study was to determine if the efficacy of imaginal exposure for symptoms of posttraumatic stress disorder (PTSD) could be improved by adding aerobic exercise. We hypothesized that aerobic exercise would enhance the efficacy of exposure therapy. Active duty service members with clinically significant symptoms of posttraumatic stress (PTSD Checklist-Stressor-Specific Version, [PCL-S], ≥25) were randomized into one of four conditions: exercise only; imaginal exposure only; imaginal exposure plus exercise; no exercise/no exposure therapy (control). Participants (N = 72) were primarily male, Army, noncommissioned officers ranging in age from 22 to 52. PTSD symptom severity decreased over time (p < .0001); however, there were no significant differences between the experimental conditions. The prediction that imaginal exposure augmented with aerobic exercise would be superior to either imaginal exposure alone or aerobic exercise alone was not supported, suggesting that engaging in exercise and imaginal exposure simultaneously may not be any better than engaging in either activity alone. A better understanding of individually administered and combined exercise and exposure therapy interventions for PTSD is warranted.

The impact of symptom burden on the health status of service members with extremity trauma.

BACKGROUND: Service members injured in combat undergo repeated surgeries and long recoveries following a traumatic injury that produce a myriad of physical and psychological symptoms. PURPOSE: To describe the severity of pain, sleep disturbance, depression, and anxiety in service members with extremity trauma sustained during combat operations at the time of discharge from the hospital and to evaluate for differences in health status between those with and without symptom burden. METHOD: Descriptive study of 130 United States Army service members. DISCUSSION: More than 80% of the service members were classified as having symptom burden. Service members who reported one or more clinically meaningful levels of pain, sleep disturbance, depression, or anxiety reported significantly worse health status compared to those without symptom burden. CONCLUSIONS: Service members with extremity trauma experience clinically significant levels of pain, sleep disturbance, depression, and/or anxiety at the time of discharge from the hospital. The greater the service members' symptom burden, the worse their reported health status.
