# How to record a general mobility assessment video AI-powered mobility assessment relies on clear, stable, and well-framed video capture. To obtain precise insights into joint range of motion, movement quality, symmetry, and functional limitations, follow this step-by-step guide when recording your general mobility videos. *** ### **1. Set Up the Right Recording Conditions** General mobility tests often involve **slow, controlled movements** of multiple joints—such as squats, hip hinges, shoulder circles, ankle mobility drills, balance tests, and multi-directional tasks. Because the goal is to detect restrictions, compensations, and movement efficiency, clarity and stability of the video are essential. #### **Indoor vs. Outdoor Recording** **Indoor (Recommended):**\ – Most mobility routines are best captured indoors where lighting and space are predictable.\ – Record in front of a plain, uncluttered background to ensure the AI can detect full body landmarks. **Outdoor:**\ – Only record outdoors if lighting is consistent and the ground is flat.\ – Avoid busy environments that may add visual noise. #### **Recording Methods** **Assisted Recording:**\ A partner films you as you complete each mobility drill. **Self-Recording:**\ Use a stable tripod or place the camera against a solid surface. For standing or floor-based mobility tests, position the device so the entire body remains visible for the full duration of the movement. 📌 **Tip:** Use a 5–10 second countdown timer so you can get into starting position before the exercise begins. ### **2. Use the Right Recording Equipment** To ensure accurate joint tracking and motion interpretation: #### **Lighting and Background** – Use **even, bright lighting**. Avoid strong shadows behind or under the body.\ – Do not record directly toward windows or bright light sources.\ – Choose a solid-color background that contrasts with your clothing for clearer body segmentation. #### **Video Quality** – **Resolution:** Minimum 720p; **1080p recommended** for detailed joint motion.\ – **Frame Rate:** 30 fps or higher for smooth capture of slow and fast mobility movements.\ – **Camera Stability:** A stationary camera gives the most reliable assessment. #### **Environmental Factors** – Ensure enough space to perform full ranges of motion without leaving the frame.\ – Remove items on the floor that could obstruct feet or limit movement. ### **3. Optimal Camera Positioning for Mobility Analysis** General mobility routines involve movements in multiple directions. To capture the entire body accurately: #### **Camera Height** – Position the camera at **hip to chest height** for most standing tests.\ – For floor exercises (e.g., hip rotations, thoracic mobility), lower the camera so all limbs remain visible. #### **Maintain Distance** – Keep the full body inside the frame, including arms overhead and feet during deep squats.\ – Adjust distance based on movement type—wider framing is better for dynamic or multi-plane motions. #### **Best Angles** – **Side View:** Ideal for squats, hip hinges, overhead reach, ankle mobility, forward bends.\ – **Front View:** Best for testing symmetry, knee alignment, balance tasks, lateral movements.\ – **Optional Rear View:** Useful for identifying compensations or asymmetries not visible from the front. 📌 *Select the angle that matches the test you are performing. When in doubt, the side view captures the largest range of joint mechanics.* ### **4. Athlete’s Form & Attire** To ensure clean data and accurate interpretation: #### **Movement Guidelines** – Move at a **controlled, natural pace**—avoid rushing or exaggerating the motion.\ – Perform the full range of each test as instructed.\ – Do not speak, turn your back to the camera, or walk out of frame mid-test.\ – Maintain consistency: repeat the movement the same way for each side. #### **Clothing Guidelines** – Wear **form-fitting clothing** that clearly defines joint outlines (e.g., leggings, fitted top).\ – Avoid loose shirts, flowing sleeves, long jackets, or scarves.\ – Choose colors that contrast with the background for maximum visibility. #### **Video Duration** – Keep each mobility test **10–40 seconds**, depending on the movement.\ – Record one exercise per clip for the cleanest AI analysis. ### **5. Optimize Video Quality for AI Analysis** To ensure your mobility assessment results are precise and reliable: – Save videos in standard formats like **MP4 or MOV**.\ – Trim footage so the recording begins in the starting position and ends when the movement is complete.\ – Avoid over-compressing videos, which reduces clarity of limb tracking.\ – Make sure your feet, hands, and head remain visible throughout the entire motion. ### **Troubleshooting Common Issues** **1. Incorrect Angle or Height**\ The body should not be cut off at the knees, head, or hands. Reposition camera if needed. **2. Poor Lighting**\ Shadows on joints—especially knees, hips, and shoulders—can reduce accuracy. **3. Unstable Camera**\ Always use a tripod or stable support. **4. Background Obstructions**\ Remove chairs, mirrors, people, or moving objects from the frame. All limbs must remain fully visible. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
