VR Holder Required for C3 & C6

Have a cardboard VR holder ready. Phone slides in, Client wears it on head. Measures vestibular sway from head position.

⚠️ SAFETY & LIABILITY WARNING You must perform this test in the corner of a room with a sturdy chair placed directly in front of you. A spotter should be present if possible. This test deliberately induces disorientation and carries a risk of falling. By checking this box, you accept full responsibility for your safety.

📖 Standard Operating Procedure

1. Environmental & Safety Setup

Location: Conduct the test in the corner of a room.
Safety: Place a sturdy chair immediately in front of the client.
Supervision: A spotter/coach must be present due to fall risks.

2. Hardware Preparation

Use an iPhone (or modern Android) with a standard hard case.
Turn device volume up to hear audio cues.
Have a Cardboard VR holder ready for Visual Conflict conditions (C3, C6).

3. Pre-Test Calibration

Select the client's Dominant/Kicking foot (Right or Left). The Kicking foot is ALWAYS placed in the back.
Select the Surface/Difficulty setting. The app will automatically build the correct testing sequence.

4. Execution Protocol

Firm/Foam (No VR): Place the phone completely flat against the client's sternum (chest).
Visual Conflict (VR): Slide the phone into the VR headset. The client must stare straight ahead at the center of the spinning spiral.

5. Fall Protocol

If the client loses balance, steps out of position, or opens their eyes during a closed-eye trial, the trial is immediately failed.
Tap the ⚠️ FALL / FAIL button on screen to record the exact time of the fall.

📱

Tap below and select "Allow" — the app uses the iPhone gyroscope to measure sway.
