The aim of the present study was to examine the effects of music and muscle relaxation techniques on sleep quality and emotional measures in individuals with Post-traumatic stress disorder (PTSD). Thirteen PTSD patients, who had no other major psychiatric, sleep, or neurological disorders, participated in the study. The study comprised one 7-day, running-in, no-treatment period, followed by two 7-day experimental periods. The treatments were either music relaxation or muscle relaxation techniques at desired bedtime. These treatments were randomly assigned. During each of these three experimental periods, subjects' sleep was continuously monitored with a wrist actigraph (Ambulatory Monitoring, Inc.) and subjects were asked to fill out several questionnaires concerned with a wide spectrum of issues, such as depression, anxiety, and life satisfaction. Analysis revealed a significant increase in objective and subjective sleep efficiency and a significant reduction in depression level following music relaxation. Moreover, following music relaxation, a highly significant negative correlation was found between improvement in objective sleep efficiency and reduction in depression scale. The study findings provide evidence that music relaxation at bedtime can be use as treatment for insomnia in individuals with PTSD.
