 You are paralyzed. It's very difficult to get recovery after three months. You need to accept your disability. What do patients need to do? Just sit at home, do nothing. That's not what we want. We want to have a better recovery, better independence. When we talk to another patient, and then he mentioned that he's active before, you know, and now becomes an impair, and then one side of the body, you know, couldn't move, and then he may bond with viewers. He's not happy. And then can we make some change? With technology nowadays, with the understanding of new science, it's become possible. We know about the brain have what we call the new plasticity. So can we use the robotic system to train the brain again to learn how to walk? So walkings, more and more, actually, the brain will learn it just like how we ride the bicycle. So with the robotic system, with the intelligent system, that may be possible. Existing robots are already doing such a thing. In the clinical trial, we can see some of the large equipment and repeat the walking. And then we can show the data that improve walking independence. But you can see those equipment have limitations, bulky, heavy, and expensive. And all the movement is maybe triggered by the joystick. This is not natural. With the advancing technology in robotic and the intelligence, actually, we can make the things more lightweight, like we can use carbon fiber and also with some of the powerful motors. So we can make the things much smarter and more easy to access. The other important thing is the intelligence. We don't want to walk with a joystick. We just want naturally walking. So nowadays, with those embedded motion sensors and force sensors, we can detect intentions. So when they move their hips, we know they want to make a step, then we will power the motor. And then they can go upstairs, downstairs. They don't need to change the algorithm. Everything is automatic. And then see in our hands, this is a robotic system. We use powerful motors. We have a new design of the gear mechanisms that can transfer the powers, amplify the power, and also all the sensors we embed in the insole. So it's easy, simple for the user to use it at home, and even in the Kinect. For the knee, it's a bit tricky because you need more power. So nowadays, we can use what we call the electric mechanical lock system to lock the knee during the stand phase and then provide the support. During the swing phase, we unlock it and then use the motor to drive it. So all the things need to be synchronized with all the intelligence. But everything can be automatic nowadays. You can see in these lights, everything can be synchronized. All the things we need is with a powerful microprocessor. Now we can do it. So everything embed together with the sensor, with the microprocessor. And the last thing is the battery. The battery to power the motor, power the lock. Is it sufficient enough? You can see now that the battery is very small and powerful. One battery that you know left, you can see it can last for two days. So you can use it for the whole day, work with the device. That's what the patient needs. More practice, better. They can't. So the technology now advances to the stage where we can do it. So let's look at how we can do the training. So you can see the patient nowadays is not limited. They can do the training indoor, outdoor, anytime they want. It's a new experience for the user and also for the clinicians. So more practice, actions have to do it. So this is the beauty of the robotic and the intelligent system. Let's look at the results. And we have a pilot test and then after 20 sessions of one-hour robotic training, we can see 30% of the lower limb functions have been improved in the patients. And 40% of the patients have been improved in the working speed. So they regain the independence. So this is important for them in the quality of life. Let's look at how the patients are feeling about those robotic systems. After training, they don't need the robotic system. They can enjoy the outdoor activity. They can go hiking. They can regain the power, strength and balance. So they don't feel tired. So this is good. The brain learned it again. And when we look at another patients, now he can walk independently. They can go stairs with confidence. They don't offer anymore. They can stand steadily after those robotic training. They can go outside. They can go to our lab anytime by himself. That's great. So what we can see now, this is with those robotic system and the intelligent system, they can give a new experience to the user and also a new experience to the stroke bear petitions. Thank you very much.
