Overview
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.
What the evidence says
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.
In practice
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.
