The Proprio 4000™ provides balance training through Dynamic Range of Motion (D-ROM) technology, which provides a multidirectional, dynamic platform and motion analysis that evaluates actual performance. The platform movement and patient’s movement work together to reproduce real-life movements and provide a controlled, yet safe, exercise. This equipment is a proven method in treating patients with lower extremity orthopedic injuries. In addition, it is effective for treating patients with stroke, brain injury, or other neurological conditions resulting in balance disturbance.
