EMDR uses bilateral stimulation as one component (its Part 4 of 8)
There are lots of reasons for this.
1. It is believed to help the body feel safer while re-experiencing past traumas. When the brain is “taxed” it is harder to hyper focus (get lost in the memory). Imagine washing the dishes, listening to an audiobook, having a conversation with someone and planning your grocery list all at the same time. The brain will lose focus, and struggle to keep track. With trauma, this blurring, struggling to focus on the trauma memory is a key way we begin to desensitize to the memory so we can actually hold it in the working memory long enough to think about the memory differently and find healing.
2. This process allows the body to be part of the therapeutic process. It allows the body to feel, sense, experience within a supportive and grounding environment. Healing trauma is not just analyzing what happens, it’s also about helping the body heal from it endured, experienced. There is some research that states REM sleep patterns are mimicked, which support this calming, connected experience.
3. It supports the goal of EMDR which considers dual attention - being aware of and experiencing the past while being aware and present in the here and now - the way in which we heal. We don’t want you to be consumed by past events. BLS helps you notice, without being absorbed. To be aware, without being lost. As a therapist, if you do get a little too far into the past - we will change how we do BLS so that you can examine, notice, be curious, reshape the past without losing your connection to the present. This is safety. This is also how we reprocess. How we begin to heal, by staying present even when triggered.
Some commons ways we do BLS is:
1. Eye Movements.
I use my hand (traditional method) but also the light bar (it’s hard on the shoulder joints lol!).
2. Audio. There are different sounds we use - most choose a beep or soft whoosh. Sometimes we pair audio with another BLS.
3. Tappers. Or Pulsers. These are small devices, shaped like teardrops, that sit in your hand and make a vibration. These too can be paired - or used individually.
