Because of the safety and flexibility, pneumatics shows prospects of application in the field of rehabilitation. This article introduced the application of pneumatics in rehabilitation for stroke.

This paper mainly introduced the development of human lower limb dynamic modeling and simulation at home and abroad, and also proposed further promising development. Its modeling methods mainly included Newton-Euler method, Lagrangian method, Kane method, etc. Analysis methods primarily included multi-rigid-body dynamics analysis and finite element analysis. It is very important to make a more reasonable model and a practical simulation of human body which can help us design rehabilitation training equipment and intelligent prosthesis

The paper overviewed the research progress of the upper limb rehabilitation training system based on virtual reality technology,introduced some kinds of rehabilitation system, especially the software design, and the application of virtual scene, virtual object and network remote in the upper limb rehabilitation, and summarized the problem of applications of virtual reality in the rehabilitation and put forward the prospects about it.

This article shows a new design of telerehabilitation system for balance function assessment and training in our laboratory. The system is based on C/S network architecture, and realizes the telecommunication through socket network communication technology. It implements the teletransmission of training data and assessment report of sit-down and stand-up, online communication between doctors and patients, and doctors'management of patient information. This system realizes remote evaluation and telerehabilitation of patients, and brings great convenience for the patients.

It is very difficult for stroke patients to complete the action of squatting-standing because their equilibrium function ability has been seriously declined. It was necessary, therefore, to do a deep research on the action of human squatting-standing and to set up an accurate model and simulation. In our modeling research, the movements of upper limbs and head was neglected, and a seven-segment model was developed to establish the coordinate system of human squatting-standing action. It calculated the knee joint moment and hip joint moment during squatting and standing by utilizing Lagrange method, and then simulated this mathematical model by utilizing Matlab. Geometric model of human squatting-standing was developed and simulated in ADAMS which proved that the established Lagrange model was reasonable. It would also provide significant theoretical references for further study and development of squatting-standing rehabilitation training equipment.

Objective To investigate the test-retest reliability of Muscle Evaluation and Treatment System on healthy adults. Methods 30 healthy adults participated in this study and were tested by Muscle Evaluation and Treatment System, designed by University of Shang-hai for Science and Thechnology and Rehabilitation Department of Huashan Hospital, on muscle strength of both sides' flexor carpi mus-cles, musculus flexor digitorum sublimis, flexor digitorum profundus, extensor digitorum muscle, extensor carpi muscles. Peak torque, peak torque per weight, largest single work, largest single work per weight, average torque, average power were the main parameters. Each partici-pant was tested 2 times, and the interval was 7 days. Results Almost perfect test-retest reliability of peak torque was performed on flexor car-pi muscles, musculus flexor digitorum sublimis, flexor digitorum profundus, and extensor carpi muscles. Moderate to excellent test-retest re-liability of average power were performed on extensor digitorum muscle. Conclusion Good test-retest reliability of Muscle Evaluation and Treatment System is proved in the study.

Objective To develop a system for hand function evaluation and training based on virtual reality. Methods 5DT Data Glove 5 Ultra, Visual Studio 2010 were integrated as the development environment and DirectX 9.0 as components, and the system was developed based on the MFC programming framework. Results and Conclusion The system can assess the fingers function, recognise gestures and can be used as a 3D environment for virtual training, which may guide the patients to take the training actively.

The lower limb rehabilitation training robots were divided into standing robots and sitting robots. Standing lower limb reha-bilitation robots included three kinds of typical structures, which mainly support body weight by suspension, and partially by air bags. Sit-ting lower limb rehabilitation robots were divided into chair and bed types, they support body weight by chairs and beds. This article re-viewed the development of products in the structures of the configuration, combined with some of the existing product and research, as well as the clinical application, .

BACKGROUND: How to design and manufacture sophisticated artificial knee joint that meets the needs of patients after knee joint replacement rely on the precise design and manufacturing technology, which ensure the prosthesis match the body and make a coordinated movement with maintained soft tissues. OBJECTIVE: To design personalized knee joint utilize of computer-aided design technology.METHODS: The human knee joint was scanned by three-dimensional laser scanning and output of the point cloud data were processed by computer-aided design technology. After that, the three-dimensional solid model of the knee was reconstructed by Geomagic and UG software.RESULTS AND CONCLUSION: A very precise three-dimensional knee model was constructed. It provides an accurate model basis for the digital manufacture of biomimetic artificial knee, virtual assembly, stress analysis, motion analysis, and surgical simulation.
