The scientists measured the severity of their symptoms before and after treatment, as well as their heart rate and blood pressure readings. They then followed up after one, three, and six months.
While this is an extremely small study (only 18 volunteers took part), the results are encouraging.
“We observed reductions in post-traumatic symptoms, including insomnia, depressive mood and anxiety that were durable through six months after the use of HIRREM,” Tegeler added.
At this stage, more research is needed. Not only was the sample size extremely small, there was no control group involved in the study, all but one volunteer was Caucasian, and only one female took part.
