Balance by NIH Toolbox V3 vs AcceloVit

This supplemental app is intended to be used in conjunction with the NIH Toolbox V3 Standing Balance test. The Standing Balance test is available in the separate “NIH Toolbox V3” app. The Standing Balance test is designed to assess postural sway and to determine participants’ vestibulo-spinal function. Children ages 3-6 are asked to complete the first four poses that are listed below; participants ages 7 years and above are asked to complete all five poses. The task order is always the same: • Pose 1: Flat surface, feet together, eyes open • Pose 2: Flat surface, feet together, eyes closed • Pose 3: On foam, feet together, eyes open • Pose 4: On foam, feet together, eyes closed • Pose 5: Flat surface, tandem stance, eyes open

AcceloVit – Explore Chest Motion Signals Without Wearables! 
AcceloVit introduces a new way to visualize mechanical rhythms of the body—using only your iPhone’s built-in sensors. By capturing subtle micro-movements of the chest with the onboard accelerometer, AcceloVit enables users to explore physiological motion patterns. AcceloVit your Bio-signals discovery tool. Whether you’re a curious learner, a researcher, or an educator, AcceloVit lets you dive into the fascinating world of biomechanical signals—without any external equipment. Key Features: * No wearables required – Works entirely with your iPhone. * Explore rhythmic body motion – Understand chest-based mechanical signals. * Two test modes – Simple mode for fast visualizations, Pro mode for detailed graphs. * Flexible durations – Choose from 5 to 60 seconds to collect motion data. How It Works: AcceloVit uses the iPhone’s high-frequency accelerometer (100Hz) to detect: * Micro-vibrations produced by natural body rhythms * Mechanical patterns generated by Chest motion cycles. These motion signals are processed using advanced DSP techniques to extract patterns such as: * 0.2-2.5Hz Motion, 0.02 - 0.4Hz Motion. * Automatic Peak per Minute detection and calculations. * Variability in signal shape and intensity. * Waveform representations of chest motion over time. How to Use: 1. Select a test duration (5–60 seconds) 2. Press Start Test 3. Place your phone gently on your chest 4. Remain still while the data is recorded 5. View your motion waveform and summary AcceloVit is designed for personal exploration, education, and research.. Disclaimer: AcceloVit is intended for personal, educational and research use only.
