ABSTRACT
Objective Based on ergonomics and biomechanics simulation technology, the biological evaluations of human muscles and the rehabilitation strategies of foot rehabilitation robot with adjustable swing were carried out and studied. Methods The human-robot coupling model of human body and foot rehabilitation robot with adjustable swing were established by using AnyBody software. Through kinematics simulation of the coupling model, the comparison between the simulation result and the theoretical calculation result confirmed reliability of the coupling model. The parameter study of AnyBody software was used to perform the biomechanical simulation of the verified coupling model. By regarding velocity and swing of the foot rehabilitation robot as variables, the muscle activity and muscle force under different combinations of variables were analyzed. ResultsDuring rehabilitation exercise, stretching performance of the foot related-muscles was effectively trained. The influence of different velocity and swing amplitude on muscles was different, and safety range of the velocity and swing adjustment was obtained. Conclusions The combined analysis of muscle activity and muscle force under different velocity and swing was achieved. The results have certain guiding significance on clinical application of foot rehabilitation robot and formulation of rehabilitation strategies in passive rehabilitation mode.
ABSTRACT
@#Objective Through investigating the status quo of the rehabilitation of the disabled in 2004 to 2007 in China, we could provide strong bases for constructing rehabilitation agencies and cultivating rehabilitation personnel in the future, as well as guide to institute plans and goals of disability rehabilitation.Methods The literature search method to obtain most of the macro data about the status quo of China's rehabilitation of the disabled and the overall rehabilitation plans and goals. The use of on-site survey to investigate five representative areas,(I.e. Beijing city, Shandong, Heilongjiang, Shanxi, and Yunnan Province), to collect and add relevant data about the status of the rehabilitation of the disabled. We did statistical analysis based on it.Results The number of the disabled obtaining rehabilitation significantly increased year by year, the growth rates were 7.3% (2005), 24.3% (2006) and 22.4% (2007) respectively. There were the biggest growth in the number of physical disabilities and mental illness rehabilitation, which far exceeding the State plans (over-the completion rates was 192.7% and 242.1% respectively), over-the completion rates of the others were all more than 10% in varying degrees. The national plans and task of rehabilitation were multiply completed. The related data in different parts had their own characteristics, which subjecting to a variety of local factors. Conclusion The overall national strategy of rehabilitation should be further improved on the basis of the "Tenth Five-Year" and the "11th Five-Year" plans and goals. The local rehabilitation strategy should be based on the local medical and health conditions, the geographical features, the rates of disability, the economic development level and the cultural background, as well as the demand of rehabilitation of the disabled.
