## What is Bilateral Stimulation Therapy?

Bilateral Stimulation Therapy (BLST) is a neuropsychological treatment adapted from a treatment called EMDR (Eye Movement Desensitization and Reprocessing). EMDR is a gold standard treatment according to the World Health Organisation for the psychological treatment of trauma. Bilateral Stimulation is a key therapeutic tool used in EMDR. 

Bilateral Stimulation simply means stimulation of both sides of the brain using eye movements, sound or tactile stimulation. Typically, it may involve moving your eyes from left to right whilst following a target or paying attention to sound in your left ear then to your right. Bilateral stimulation is referred to as a ‘bottom – up’ approach as it works on the emotion engine of the brain, the limbic system. This approach reduces emotional distress which allows the cortical areas of the brain (thinking, reasoning, planning) to become more active and effective. The effect of this approach is often experienced more quickly and easily.

Because this therapy uses one element of EMDR, it is called BLST so as to not confuse or give the user a wrong impression about the complete standard EMDR therapy. BLST uses one part of EMDR, and therefore 2can be practiced at home, work or any quiet environment where you can spend five minutes or so undisturbed much like meditation. For more information about BLST and EMDR please visit www.mromeopsych.com/blst

This minimal app uses bilateral click which, when activated, sounds alternately in each ear. The speed, tone and length of the practice can be set by the user. The App has two options: 1. BLST mode (bilateral stimulation with sound) and 2. FLASH (an adaption of Dr Phillip Manfield’s FLASH technique. Please visit https://www.flashtechnique.com for more information).

This app is a clinical tool for psychologists, psychiatrists, EMDR therapists and their patients. While information is provided at www.mromeopsych.com/blst, you should consult your EMDR therapist before using it. Please note: Persons suffering with complex PTSD Dissociative Identity Disorder, Borderline Personality, Schizophrenia or unstable neurological conditions (eg; epilepsy) should not use this product without consultation with your therapist.

As we are frequently updating this app to improve it’s functionality and increase its features, we ask that any comments or suggestions that you have, please contact us at admin@mromeopsych.com. Thank you.

### 2/5 — Meh

*2022-02-28*

The sound isn’t very loud even when adjusted and “options” are repetitive. Also flash is an auditory flash not visual

### 5/5 — Very good EMDR app

*2020-07-28*

Good sounds and easy to use controls and interface. I love the sleep mode function.

### 4/5 — Useful tool, but needs more sound options and preset time options.

*2020-04-18, version 1.1*

I downloaded this app as a tool to use with my clients now that we are exclusively doing video-therapy during the pandemic. I like how basic and easy to use this is. I especially like the $.99 price, as I will be asking my clients to buy it. The preset time limits are too short for the BLS as well as Flash. I don’t feel there should be a time limit on either of those, as the user can press stop when the therapist tells them to. For the sleep setting, the 30 minute time frame is fine. I also would like to see more options for sound. I would prefer to be able to choose from beeps/tones in addition to the clicks.

Feedback for a future update other than what I suggested above would be to allow for an external music source to use with Flash (or sleep), with the clicks/tones to be layered over it.  Once a client learns Flash, it is an excellent tool that can use on their own.  However, I have found having them listen to “happy music“ is more effective than just thinking of something positive- which can be difficult when someone is anxious. I like the quickened tones that indicate when they user should blink. I would also like to see an option where the therapist can choose how frequently the quickened tones are played. 

Overall, I think this is a good app that will allow any therapist trained in EMDR and Flash to enhance their video-therapy sessions.

### 5/5 — Works well 🦋

*2019-11-06*

Helps very good ok
