Description
Tim Lehmann and co-authors study balance control after knee surgery in a 2026 paper. Athletes who had anterior cruciate ligament reconstruction, 17 in total, were compared with 13 healthy controls. All stood through 100 surprise platform shifts while hip motion and brain signals were recorded by mobile EEG.
The surgery group showed higher hip acceleration during early adjustment and late re-stabilizing. Brain response signals were larger, and information flow in a front-central network dipped early then rose later. The authors read this as more effortful, less automatic control, which may raise re-injury risk.
