Gait rehabilitation system A3-2

robotic

The A3-2 is a gait training and assessment robotic device designed for rehabilitation of walking dysfunction. It integrates a computer control system, gait correction mechanism and a synchronized treadmill to deliver repeatable, trajectory-guided training and objective assessment for patients recovering walking function.

Therapeutic effect

• Promotes restoration of a normal walking pattern in early gait training.
• Helps inhibit and relieve spasticity and improves joint mobility.
• Provides dynamic weight support to enhance proprioceptive input and maintain or improve muscle strength.

Features

• Designed according to the normal gait cycle to reproduce physiological walking patterns.
• Imported servo motors for precise control of joint angles and walking speed.
• Active and passive training modes to accommodate different rehabilitation stages.
• Soft, adjustable guiding force for patient comfort and adaptable assistance.
• Gait correction capability to address abnormal gait patterns via adjustable gait offset.
• Spasm detection and protection system to monitor and safeguard the patient.
• Suspension system with two support modes: static support (vertical lift/transfer) and dynamic support (adjusts center of gravity during the gait cycle).
• Patented treadmill with automatic synchronization between treadmill speed and gait corrector, providing cushioning to protect knees and ligaments.
• Virtual-scene feedback training to increase engagement and motivation during therapy.
• Software platform to build a patient database, record treatment plans, adjust protocols for precise control, display real-time leg resistance curves and monitor active/passive leg training and patient active force.
