| Objective:By applying the technology of PNF(proprioceptive neuromuscular facilitation neuromuscular ontology technology)in the treatment of knee osteoarthritis,to clarify the relation of improved proprioception and those symptoms such as pain,joint activities,explore the knee osteoarthritis pathogenesis of muscle source,provide the basis for clinical rehabilitation and treatment.Methods:1.take 60 cases of KOA patients as the research object,design two kinds of exercise prescription,a single muscle strength training and a PNF training,then observe the changes of body sensation and muscle function to improve the effect of the knee joint function.Independent sample t test was used for the differential analysis of measurement data between groups.Pearson correlation was used to analyze the correlation of normal data.Spearman correlation was used to analyze non-normal data.2.Isokinetic force trainer was used to measure the threshold of passive motion sensation before and after training and to evaluate the change of proprioception.Results:after treatment,experimental group get better function than that of control group,and lower joint pain degree than the control group.After the spearman correlation analysis,joint function positively related changes and proprioception,the greater the change with the change of proprioception,the greater the joint function(P<0.05).The experimental group received PNF training,which not only enhanced the proprioception,but also increased the score of joint function.Conclusion:1.PNF training can effectively stimulate the transmission of knee body information to the central region.The neuromuscular feedback information stored in the cerebral cortex after processing,the downside of feedback to enhance proprioceptive sensitivity,KOA patients for PNF training is necessary。2.PNF is an effective component of motion therapy for knee osteoarthritis by treating the comprehensive input of tactile sense,visual sense and joint proprioceptive sense,which can double strengthen the static stability and dynamic stability of knee joint. |
