Bilateral Stimulation
The Infinity Pattern
The infinity (lemniscate) pattern moves the visual target along a figure-eight path. Learn why clinicians use it and how it compares to horizontal BLS.

Introduction
The infinity pattern moves the visual target along a horizontal figure-eight (lemniscate). It preserves left–right alternation while adding vertical trajectory, which some clients report finding smoother and less mechanical than pure horizontal movement.
Evidence summary
There is limited comparative evidence between patterns. Clinician reports suggest infinity can be a useful variation for clients who find pure horizontal motion tiring or repetitive.
Clinical use
The infinity pattern is a good default alternative when horizontal feels rote. BilateralSync switches patterns instantly so clinicians can experiment mid-session and settle on the client's preferred trajectory.
Frequently asked questions
- Is infinity better than horizontal?
- Not universally. It is a useful variation; clinical judgement and client preference guide selection.
