Professor Li Jianan, the president of the International Association of Rehabilitation Medicine and an academician of the National Academy of Medical Sciences, believes that understanding the human walking mechanism is the premise of developing excellent new products. In the future, the lightweight, low-cost, next-generation power-assisted walking rehabilitation robot market for individual users has broad prospects.
Li Jianan is currently a Fellow of the National Academy of Medical Sciences, Chairman of the International Society of Physical Medicine and Rehabilitation Medicine, Chairman of the Chinese Medical Association Physical Medicine and Rehabilitation Medicine Branch, Director of the Rehabilitation Medical Center of the People's Hospital of Jiangsu Province, and Dean of the School of Rehabilitation Medicine of Nanjing Medical University. He specializes in sports and rehabilitation of cardiovascular disease, basic and clinical research on motor control disorders, nerve block, and rehabilitation of spinal cord injury. Leading the establishment of the first fully configured gait analysis laboratory in China's general hospitals, taking the lead in the development of nerve block therapy for muscle spasm in China.
So far, Li Jianan has trained 15 graduates and 45 masters; 1 post-doctor, 9 doctors and 7 masters. Visiting professors from Zhejiang University, West China Medical College of Sichuan University, Xinjiang Medical University, Shanghai University of Traditional Chinese Medicine, Fujian University of Traditional Chinese Medicine, Heilongjiang University of Traditional Chinese Medicine, Shanghai Sports University, and Nanjing Institute of Physical Education.
Reed Jianan demonstrates "gait"
Assisting the rehabilitation robot is the hope of returning to normal walking
For those unfortunate strokes and brain trauma patients, being able to resume normal walking should be a dream. Some physiotherapists let the patient try to walk on the treadmill, and manually help the patient move their lower limbs to complete the normal walking pace. Helping rehabilitation robots can share the pressure of their children's pension.
The assisted rehabilitation robot combines traditional walkers with robotics such as rehabilitation medicine, physiology, and motion control. The user is assisted to protect the body support and realize the auxiliary walking function. For the walking dysfunction of the elderly and the paralyzed patients, the robot can perform the walking rehabilitation training for the user, overcoming the problems of the user's muscle strength reduction and coordination ability reduction.
Deep understanding of the human walking mechanism is the key
Li Jianan believes that an in-depth understanding of the human walking mechanism is a necessary condition for the development of excellent walking rehabilitation robot products. He pointed out that the assisted walking rehabilitation robot can only imitate the walking movement of the human being, but can not imitate the gait of the human. The "gait" is the behavioral characteristic of the walking movement, and the robot can not walk out of the human gait. Then, Jian Jianan introduced the walking mechanism of the human body from the perspective of anatomy, described the state and function of the hip, knee, ankle joint and corresponding muscle groups in the normal adult during the walking cycle, and introduced how to use modern science and technology to walk on the human body. The kinematics and dynamics of the data were collected and analyzed.
