Maximum Safety during Stance
The system joint detects small, unintentional steps during stance and remains locked. Natural Change from Stance to Gait
If the patient changes from stance to gait, the ultra-fast high-performance microprocessor registers the change in real time using the sensor data and switches the system joint to walking mode. The new technology of the NEURO HiTRONIC system knee joint enables the patient to take the first step with the orthosis leg when changing from stance to gait. This is particularly useful for patients whose legs are both treated with an orthosis with stance phase control e.g. after suffering from paraplegia on both sides. If the patient stops or interrupts the step, the NEURO HiTRONIC immediately switches back to standing mode. Automatic Stance Phase Control during Gait
In walking mode, the knee is locked in the stance phases of the gait cycle starting at terminal swing. The sensor system detects the gait phase regardless of the angle between the lower leg and the ground as well as the knee angle. Thus, the knee is locked prior to initial contact. This also applies if the foot meets the ground when stumbling or when walking downhill with the knee bent. The flexion of the knee is prevented in all stance phases up to mid stance. Consequently, the knee can be extended without resistance during swing phase. At terminal stance, the knee is unlocked so that it can be bent starting at pre swing to execute the swing phase. The knee flexion is carried out without resistance, thus achieving a physiological knee flexion in mid swing. Stumbling due to insufficient knee flexion is therefore impossible. The extending movement of the knee during swing phase is supported by an air spring, which makes walking a smooth and safe experience. In terminal swing, the system knee joint is locked again without play or noise. When changing between short and long or slow and fast steps, sensors, electronics, microprocessor and hydraulics ensure that the system joint locks and unlocks automatically as described above. In order to adjust the NEURO HiTRONIC to the patient's individual safety needs, the orthotist can set the exact locking time in terminal swing and unlocking time in terminal stance via the Expert app. |
