Simulation motion tracker A7-2

Product overview
The A7-2 is a clinical gait analysis system that captures full lower-limb kinematics using wearable electronic sensors. It provides temporal, geometric and mechanical gait parameters, supports objective quantitative assessment and includes built‑in 3D gait reconstruction for multi-angle review and standardized report generation.

Key features

• Real‑time wireless transmission: stable coverage within 10 m with live visualization of lower‑limb posture.
• Gait data archiving: all recorded gait sequences stored in the system database for instant playback and analysis.
• Automated gait assessment: intelligent processing converts raw sensor signals into clinical indicators such as gait cycle, step length and cadence.
• 3D motion reconstruction: replay recorded gait sequences in unlimited 3D rendering to compare pre‑ and post‑therapy trials.
• Extended operation: high‑capacity rechargeable battery enabling continuous use for over 10 hours.
• Customizable reports: full data report printing with selectable indicators to match clinical requirements.

Indications
Indicated for clinical gait analysis in rehabilitation medicine, orthopedics, neurology, neurosurgery and other clinical departments across medical institutions.

Core functions

• Data playback: unlimited 3D reconstruction of recorded trials for detailed kinematic review and treatment comparison.
• Assessment: automatic calculation and visualization of key indicators including gait cycle, joint displacement and joint angle variation via charts and curves.
• Comparative analysis: supports pre‑ vs post‑intervention comparison and patient vs normative healthy gait matched by body size.
• 3D multi‑view visualization: built‑in left, top, rear and free‑drag perspectives for targeted joint inspection.

Visual feedback training modes (4 types)

• Segmented motion training: isolated practice of hip, knee and ankle kinematics within separated gait phases.
• Continuous motion training: coordinated full‑cycle training for unilateral lower‑limb hip, knee and ankle.
• Walking & balance training: center‑of‑mass shift and single‑limb stance exercises.
• Software assessment interface: 3D skeletal kinematic simulation view for feedback during training.
