✅ Feature Highlight
- Precise ROM (Range of Motion) Control for Safe Rehabilitation
BCI ACL knee brace isn’t just about rigid support — it gives you fine-tuned control over motion. With plug-in ROM stops, you can lock extension at 0°, 10°, 20°, 30°, or 40° and limit flexion at up to eight settings (0°, 10°, 20°, 30°, 45°, 60°, 75°, 90°).
For early rehab when motion must be restricted, the brace also supports immobilization at 0°–30°. As your healing progresses, simply adjust the stops to unlock additional range.
This dual functionality (immobilization + adjustable motion) helps balance protection and mobility, letting you guard against hyperextension, control excessive bending, and progressively restore natural movement.
