But what if sleep could be achieved not by a substance, but through &#8216;balancing&#8217; brain activity?<\/p>\n<p>Researchers at Wake Forest Baptist Medical Center have conducted a pilot clinical study <strong>to determine whether a non-invasive approach, that uses musical tones to balance brain activity, can &#8216;reset&#8217; the brain and effectively reduce insomnia<\/strong>.<\/p>\n<p>The study, was published online in October, advance of print, in the journal<em> Brain and Behavior<\/em>. It was funded by a $26,696 grant from Brain State Technologies, LLC, Scottsdale, Ariz., the company that owns the technology used in the study.<\/p>\n<p>Charles H. Tegeler, M.D., professor of neurology at Wake Forest Baptist and principal investigator of the study explained how the technology works. &#8220;<strong>The human brain is made up of the left and right hemispheres that work together as parallel processors<\/strong>. When a person undergoes trauma or a major stressor, their autonomic survival responses kick in and the brain can become unbalanced. If those imbalances persist, symptoms such as insomnia can result. Our study looked at a new technology that is intended to facilitate greater balance and harmony in brain frequencies, which may result in improved symptoms.&#8221;<\/p>\n<p>The new technology is called HIRREM, high-resolution, relational, resonance-based, electroencephalic mirroring or, as it&#8217;s commercially known, Brainwave Optimization\u2122. The non-invasive procedure uses a system that is designed to reflect the brain&#8217;s frequencies back to itself using musical tones. R<strong>esonance between the musical tones and the electrical energy in a person&#8217;s brain can bring balance to the two hemispheres of the brain.<\/strong><\/p>\n<p>Study results were based on a change in the Insomnia Severity Index (ISI) which measures the severity of sleep disruption using a zero-to-28 point scale; the median ISI for study participants was between 18.7 and 18.9, which is considered moderate-to-severe insomnia.<\/p>\n<p>Researchers found that the HIRREM group had a 10.3 point drop in ISI, improved insomnia symptoms and, clinically moved into a category of &#8216;no insomnia&#8217; or &#8216;sub-threshold insomnia&#8217;. The control subjects, who continued their existing insomnia treatment without HIRREM, showed no change in ISI. <strong>However, when the crossover control group received HIRREM therapy, the results were indistinguishable from those of the original HIRREM group.<\/strong><\/p>\n<p>This unblinded, wait-list control, crossover study enrolled 20 participants (14 women and 6 men). Ten people were randomized to receive HIRREM sessions, plus usual care; the remaining 10 were assigned to the wait-list control group. An initial assessment determined the symmetry, or balance, in amplitude and frequencies between the brain hemispheres and data collection included a subject&#8217;s ISI and other measures including blood pressure and neurocognitive function tests.<\/p>\n<p>Study participants randomized to HIRREM underwent eight to 12 sessions that each lasted between 60-90 minutes. <strong>The sessions involved reclining in a zero gravity chair and placing sensors over numerous locations on both sides of the scalp<\/strong>. A musical tone, determined by a mathematic algorithm and based on the dominant frequency in a floating middle range of the participant&#8217;s EEG frequencies, was played back to the participant through ear buds. Resonance between musical tones and oscillating brain circuits is designed to allow the brain to auto-calibrate, moving towards better balance, with associated improvement in symptoms.<\/p>\n<p><strong>The limitations of the study include the small number of study participants and the absence of a sham-placebo control group which prevented blinding<\/strong>. This means it is possible that the changes observed with HIRREM, could be due to a placebo effect. In addition, because HIRREM therapy involves social interaction and relaxation, there may be other non-specific mechanisms for improvement, in addition to the tonal mirroring.<\/p>\n<p>Although the researchers believe that the degree of improvement and length of time it persisted (for four weeks after the last session) suggests real change through HIRREM, Tegeler is planning a larger clinical trial using a sham placebo, to confirm the HIRREM effect and further explore the technology.<\/p><\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the Wake Forest Baptist Medical Center press release via EurekAlert!: If you are among the 50 percent of Americans who suffer from insomnia, then you have probably tried everything&#8230; <a class=\"read-more-link\" href=\"https:\/\/therapytoronto.ca\/news\/2012\/11\/study-examines-new-therapy-for-insomnia\/\">Read more &raquo;<\/a><!-- AddThis Advanced Settings generic via filter on get_the_excerpt --><!-- AddThis Share Buttons generic via filter on get_the_excerpt --><\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[10,6],"tags":[42,67,362],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/8526"}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=8526"}],"version-history":[{"count":3,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/8526\/revisions"}],"predecessor-version":[{"id":8603,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/8526\/revisions\/8603"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=8526"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=8526"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=8526"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
