Bilateral stimulation (BLS): what it is, modalities, and what science supports
Alternating bilateral stimulation (BLS) uses rhythmic stimuli that alternate left and right: visual tracking, sounds in each ear, or tactile input. It is a core component of EMDR and research supports its role in processing difficult memories.
Modalities of bilateral stimulation
Visual: eye tracking of a stimulus moving horizontally. Auditory: tones alternating in each ear (headphones recommended). Tactile: alternating vibrations or taps on hands or knees.
Online bilateral stimulation with Dualmove
Dualmove is session software, not a brochure: it delivers visual and auditory BLS for telehealth or in-person work. The therapist controls speed, direction (including infinity), color, shape, and audio (10 wall sounds and 10 ambient presets); the patient opens a link in the browser, with no account.
