Baseline aligned

At T0, both visual pathways intentionally start from the same illustrative position so the later divergence is easier to see.

Mean recovery difference≈ 0.97 weeks faster with VR

Recovery criterion

Three consecutive zero scores

The study considered three consecutive Pain Arch Test scores of 0 as an indicator of recovery.
