Wall Game

The patient stands in front of a wall of metal pistons. One piston at a time extends and lights up; the patient must strike it before the reaction window ends (3 seconds by default). On every successful hit the piston retracts and a new target lights up somewhere else.

The grid size (3×3 by default), target pace and spatial spread are configurable: higher targets engage shoulder elevation, lateral ones engage trunk rotation. Impact sound, a short haptic pulse and the target flash give instant feedback on every move.

This exercise rebuilds upper-limb responsiveness: reaction time, shoulder range of motion, lateral reach and trunk rotation. The varied target positions demand active visual search and fast movement planning.

2. Parkinson's and MS — movement initiation and response speed
3. Orthopedic shoulder and arm recovery

Select “Wall Game” from the games list, pick a level set, and once the patient wears the headset use the “environment preparation” phase to adjust height and position; then press “start exercise” so counting begins from zero.

1. Grid size, level duration and the per-piston timeout are set in the Level Designer.
2. For accuracy goals, shorten the piston timeout to match the patient's capacity.
3. Difficulty and the environment (lighting, colors, backdrop) can also change mid-session.

1. Reaction time per strike (average and trend)
2. Successful strikes and actions-in-time
3. Accuracy — missed pistons included
4. Survival time and total score
