Auricular Acupuncture for Sleep Disturbance in Veterans With Post-Traumatic Stress Disorder: A Feasibility Study

The purpose of this study was to examine the feasibility and acceptability of an auricular acupuncture (AA) insomnia regimen among Operation Iraqi Freedom and Operation Enduring Freedom veterans with post-traumatic stress disorder and sleep disturbance. Secondarily, this study examined the effect of an AA insomnia regimen on objective sleep times by wrist actigraphy, subjective sleep times by sleep diary, and sleep quality ratings utilizing the Pittsburg Sleep Quality Index. Veterans (n = 30) were randomized to receive a 3-week AA insomnia regimen. Veterans receiving the AA insomnia regimen reported it as a more acceptable treatment for sleep disturbance than subjects in the control group (AA group median = 5 vs. control group median = 3, p = 0.004). Significant differences between groups were found on the sleep quality and daytime dysfunction components of the Pittsburgh Sleep Quality Index (p = 0.003, p = 0.004). No other significant differences between groups were found for objective and subjective sleep measures. These results suggest that an AA insomnia regimen may improve sleep quality and daytime dysfunction among veterans with post-traumatic stress disorder. Future, large-scale, prospective clinical trials are needed to examine AA effects on sleep.
