| Sitting posture |
Both shoulders are in a 30° bent posture. In addition,
both knees are in a 30° bent posture. The subjects are expected to maintain this
position for 30 s, with their center of gravity coinciding with the red center in
a yellow circle on the monitor. |

| The knee bend and the other leg knee extend |
The subjects maintain the sitting position for 30 s,
with their center of gravity coinciding with the red center in a yellow circle on
the monitor. On weight-bearing, the red stick rises, and the number of times the
blue target is exceeded is recorded. The knee flexion angle is gradually increased
to 30°, 45°, 60°, and 90°. |

| Walking a tightrope |
The subjects walk a tightrope by alternate weight
shifting to left and right and are expected to reach the target without falling.
They are required to widen bent knees quickly to go over obstacles, with the wind
and flags providing a visual and balance challenge. |

| Penguin teeter-totter seesaw |
By alternate weight shifting to the left and right,
the subjects are expected to catch fish without falling on the ice, which will
cause the ice to tilt. The scores that can be obtained in accordance with the fish
are diverse. |

| Balance skiing |
By moving the body’s center of gravity to the left or
right, the subject passes between 19 flags; moving the center of the body forward
helps increase the speed. Do not pass the flag, 7 s deduction is given per
one. |
1.5–2 |
|
| Rolling marble board |
The subjects tilt the platform in multiple directions
by shifting weight onto the ankle joints to place the ball in the target. If it
passes through the stage, added additional time to the next stage. |
1.5–3 |
|
| Balance Mii |
The experimenter moves the body’s center of gravity in
multiple directions with the subject’s Avatar (Mii) in a soap bubble; the goal is
to steer to the target point. The subject has to be careful not to hit the wall,
rock, or bees. |
