Bilateral Stimulation Therapy 1.2

Review of Bilateral Stimulation Therapy (BLST)

Bilateral Stimulation Therapy (BLST) is a neuropsychological intervention derived from Eye Movement Desensitization and Reprocessing (EMDR), a treatment recognized by the World Health Organization as an evidence-based approach for trauma-related disorders. EMDR incorporates bilateral stimulation as a core component, which BLST adapts for more accessible application.

Bilateral stimulation involves engaging both hemispheres of the brain through stimuli such as eye movements, auditory signals, or tactile sensations. Typically, this includes moving the eyes from side to side, following a visual target, or alternating sounds between ears. This method is characterized as a ‘bottom-up’ approach, targeting the limbic system—the emotional center of the brain—to reduce distress. Consequently, this facilitates increased activity in the cortical regions responsible for higher-order functions like reasoning and planning. Therapists often observe that the effects of BLST can manifest more rapidly and with less complexity compared to full EMDR sessions.

Due to its basis in a portion of standard EMDR protocols, BLST is explicitly distinguished to prevent misinterpretation as a comprehensive treatment. It is designed as a self-administered technique suitable for brief practices—around five minutes—in quiet environments at home or work, similar to meditation. Further information about BLST and EMDR can be found at www.mromeopsych.com/blst.

The associated application utilizes bilateral clicks—alternating sounds in each ear—with adjustable speed, tone, and duration. It offers two modes: 1. BLST mode, which provides bilateral auditory stimulation; and 2. FLASH mode, an adaptation of Dr. Phillip Manfield's FLASH technique. Details about this technique are available at https://www.flashtechnique.com.

This app serves as a clinical tool for psychologists, psychiatrists, EMDR practitioners, and their clients. Although information about BLST is accessible online, users should consult their healthcare provider prior to use. Caution is advised for individuals with complex PTSD, Dissociative Identity Disorder, Borderline Personality Disorder, Schizophrenia, or unstable neurological conditions such as epilepsy—medical advice should be obtained before proceeding.
