Motion assessment system 3DMA

gaitposturewith 3D visualisation

Overview
3DMA is a marker-based 3D optical motion capture system for biomechanical assessment. The product integrates a capture engine and dedicated biomechanics modules with configurable packages for gait, running, cycling, golf, jump and joint assessments. It delivers streamlined capture-to-report workflows and access to normative comparison data.

Key features

• Real time: metrics, graphs and biofeedback available during acquisition.
• True 3D: full 360° scene reconstruction and multi-view playback.
• High frame rate: capture options typically from 50 Hz to 360 Hz (camera-dependent); select configurations and cameras support higher rates up to referenced camera limits.
• High accuracy: marker tracking error reported under 1 mm in well-calibrated volumes.
• Scalable setups: single-joint protocols to full-body assessments.
• Comparison and integrations: record comparison mode and support for third-party devices.

Analysis protocols (available)
Provided protocol packages address clinical and performance use cases, including:

• Gait: lower-limb and full-body protocols (Helen Hayes, Rizzoli variants).
• Cycling: full-body analysis on free or fixed trainers, bike geometry measures (Road, TT-Aero, MTB).
• Golf: swing analysis at 100–360 FPS depending on camera choice.
• Jump: Counter Movement Jump, Squat Jump protocols.
• Running: treadmill and overground running protocols (recommended camera counts and frame rates included).
• Joint and functional assessment: joint-specific protocols and functional tests (e.g., Star Excursion Balance Test, Landing Error Scoring System).
• EDDO portable option: one-sided portable 3D system for march, running and cycling up to 120 FPS.

What a protocol includes
Each protocol package contains standardized components to accelerate setup and processing:

• Marker configuration / markerset
• Predefined graphs and visualizations
• List of relevant biomechanical parameters
• Automatically detected events and calculated metrics
• Metric dashboards for quick assessment
• Report template for export and clinical documentation

What is included in 3DMA
3DMA bundles software and recommended hardware items; typical inclusions are:

• Software: licensed analytics platform (licensing model depends on package — annual or permanent options referenced for specific use cases). Compatible with OptiTrack, Vicon, Simi, C3D and TRC files.
• Capture configurations: recommended camera counts from 4 to 20 cameras depending on protocol and capture volume.
• Capture rates: configurable per camera model and protocol (typical ranges 50–360 Hz; some camera options support higher rates).
• Integrations: synchronized video references, force platforms, pressure mats, ANT+ devices, EMG and other third-party sensors.
• Training & support: initial user training and installation support (support languages indicated: English and Spanish on product page).

Selected technical and operational notes

• Minimum PC (recommended): Intel Core i5 (i7 preferred for 8+ cameras), 4-core CPU recommended for larger setups; RAM 8 GB (16 GB preferred); ~4 GB for installation plus additional storage for captures; Windows 10/11; mid-range NVIDIA GPU compatible with DirectX 12 recommended; sufficient independent USB controllers (USB 3.0 required for some cameras).
• Frame rate guidance: gait/cycling typically 50–100 FPS; fast gestures (golf swing) require higher FPS.
• Accuracy and calibration: calibration required after camera installation; re-calibrate after camera movement; recommended monthly recalibration; initial calibration time ~15 minutes, experienced users ~3 minutes.
• Lighting: designed for indoor use with standard lighting; avoid direct sunlight in capture volume.
• Camera recommendations: cycling setups from 4+ cameras; gait/running/golf 6+ cameras; large labs 8+ cameras. Reference video cameras (e.g., Logitech C920/BRIO) or high-speed IDS models can be integrated; up to 2 reference video cameras supported concurrently.

Complementary capabilities

• Realtime dashboards and report templates enable rapid result delivery to clinicians and researchers.
• Supports single-side portable analysis (EDDO) or full-body laboratory setups.
• Multimodal integration with force plates, pressure mats and EMG for combined biomechanical assessments.
