Effect of tendon and bone setting manipulation combined with Kinesio Taping on de Quervain disease

Objective:To observe the effect of the treatment of tendon-regulation and bone-setting manipulation and Kinesio Taping on patients with de Quervain Disease.Methods:60 cases with de Quervain Disease were divided into 30 treatment group and 30 control group according to random number table.The observation group was treated withtendon-regulation and bone-setting manipulation and Kinesio Taping,and the control group was given Votalin emulsion combined with Kinesio Taping.The patients were evaluated and compared according to the VAS before and after treatment,the degree of tenderness,the methods of electric integral value(integral electromyogram,iEMG),the degree of wrist ulnar deviation,and the cooney wrist score,and the curative effect was observed using the diagnostic curative effect criteria of TCM disease(the evaluation process was blinded).Results:Compared with the same group before treatment,after treatment,the pain and tenderness of the two groups were reduced,iEMG value increased,the ulnar deviation of the wrist increased,and the cooney wrist score increased(all P<0.05);the improvement of the treatment group was significantly better.In the control group,the difference was statistically significant(P<0.05)and the total effective rate of the treatment group was 93%higher than that of the control group 80%(P<0.05).Conclusion:The combination of the tendon-regulation and bone-setting manipulation combined with the Kinesio Taping can effectively reduce the pain and tenderness of the patients withde Quervain Disease,increase the ulnar mobility of the wrist joint,and improve the joint function of the wrist joint.

Optimization and Mechanical Accuracy Reliability of a New Type of Forging Manipulator

Researches on forging manipulator have enormous influence on the development of the forging industry and national economy.Clamp device and lifting mechanism are the core parts of forging manipulator,and have been studied for longer time.However,the optimization and mechanical accuracy reliability of them are less analyzed.Based on General Function（G_F）set and parallel mechanism theory,proper configuration of 10t forging manipulator is selected firstly.A new type of forging manipulator driven by cylinders is proposed.After solved mechanical analysis of manipulator＇s core mechanisms,expressions of force of cylinders are carried out.In order to achieve smaller force afforded by cylinders and better mechanical characteristics,some particular sizes of core mechanisms are optimized intuitively through the combined use of the genetic algorithms（GA）and GUI interface in MATLAB.Comparing with the original mechanisms,optimized clamp saves at least 8 percent efforts and optimized lifting mechanism 20 percent under maximum working condition.Finally,considering the existed manufacture error of components,mechanical accuracy reliability of optimized clamp,lifting mechanism and whole manipulator are demonstrated respectively based on fuzzy reliability theory.Obtained results show that the accuracy reliability of optimized clamp is bigger than 0.991 and that of optimized lifting mechanism is 0.995.To the whole manipulator under maximum working condition,that value exceeds 0.986 4,which means that optimized manipulator has high motion accuracy and is reliable.A new intuitive method is created to optimize forging manipulator sizes efficiently and more practical theory is utilized to analyze mechanical accuracy reliability of forging manipulator precisely.

FUZZY MODEL-FOLLOWING ADAPTIVE CONTROL DESIGN FOR ROBOT MANIPULATORS

The increasing demand on robotic system performance leads to the use of advanced con- trol strategies. This paper proposes a method of nonlinear feedback control introducing fuzzy infer- ence into model-following adaptive control for the nonlinear robot manipulator systems. The fuzzy inference is introduced to treat the nonlinearities of the control systems. Furthermore, the stability of the system is discussed by the fuzzy stability theory based on the Lyapunov's direct method. In the closed loop, the robotic system asymptotically converge to the reference trajectory with a pre- scribed transient response.

Clinical observation of sinew-regulating bone-setting manipulations plus exercise therapy for chronic non-specific low back pain

Objective:To evaluate the clinical efficacy of sinew-regulating bone-setting manipulations plus exercise therapy in treating chronic non-specific low back pain(CNLBP).Methods:A total of 65 CNLBP patients were divided into two groups by the random number table method.Thirty-three cases in the treatment group were intervened by sinew-regulating bone-setting manipulations plus exercise therapy;32 cases in the control group were intervened by medium-frequency electrotherapy plus exercise therapy.Before and after treatment,visual analog scale(VAS),dynamic and static muscle endurance of low back,median frequency(MF)of surface electromyography(sEMG)and Oswestry disability index(ODI)were used to evaluate the low back function.The therapeutic efficacy was estimated after treatment.Results:The two groups each had 2 dropouts during the study.The total effective rate was 90.3%in the treatment group versus 66.7%in the control group,and the between-group difference was statistically significant(P<0.05).After treatment,the VAS score,dynamic and static muscle endurance of low back,MF of sEMG and ODI score all changed significantly in both groups(all P<0.05);all the items in the treatment group were significantly different from those in the control group(all P<0.05).Conclusion:Sinew-regulating bone-setting manipulations plus exercise therapy can effectively release pain in CNLBP patients,increase muscle endurance of the low back and improve the quality of life,and its therapeutic efficacy is more significant than that of medium-frequency electrotherapy plus exercise therapy.
