Task 1 · Sway measurement
Sway Stability
Two stances, same protocol: hold the red crosshairs over the bullseye center for 5 seconds, then we record how far you drift over the test window. The double-leg vs single-leg delta is your stance-asymmetry score.
Source: IMU (not connected). On the paired GO Balance board the crosshairs follow center-of-pressure in real time.
Current stance
Double-leg stance
Stand with BOTH feet centered on the board, heels on the X stickers. Get comfortable, then place the red crosshairs in the middle of the bullseye.
