An alternative method of bilateral stimulation: alternating light taps on the knees, shoulders, or hands. It can be performed by the therapist or self-administered by the client through the Butterfly Hug. Vibrating pulsers (devices in each hand) are another option. The alternating activation of left- and right-side sensation supports the same mechanism of bilateral processing as eye movements.
Step-by-step guide
- Choose the method: tapping on the knees, shoulders, or hands
- If the therapist is doing it — ask permission for the touch
- Have the client hold the target image in mind
- Alternate left–right taps at a rate of 1–2 per second
- The pressure is light, not painful
- After the set: "What is happening?" or "What is the SUD?"
When to use
- Vision impairment or inability to track movements
- Epilepsy, photosensitivity
- Eye trauma or trauma to the visual system (could be a trigger)
- Work with children
- Client preference
