Comparative Observation Of The Effect Of PNF Stretching Training And Static Quadriceps Stretching On The Treatment Of Patellar Tendinopathy

Objective:To verify the clinical efficacy of PNF stretching training and static traction through PNF stretching training and static traction four head muscle for treatment of patellar tendon terminal disease.Methods:48 cases of patellar tendon terminal disease were selected from October 2017-2018 Month 2 in the outpatient Department of Orthopaedics hospital in Sichuan province,which were randomly divided into static pull training group and PNF stretching training group for four weeks intervention,compared with Visa index,VAS score,Knee Extension Knee Unit peak torque,four head muscle flexibility.Results:1.For the VISA index,the two groups were significantly higher than the pre-intervention and post-intervention 1 weeks after the intervention(P<0.05).The VISA index of the PNF stretching group was higher than that of the static training group(P<0.05).2.For the VAS score,the two groups were significantly lower than the pre-intervention and 1 week intervention after 4 weeks of intervention.The difference was statistically significant(P<0.05).Between the two groups,there was no significant difference between the two groups after 4 weeks intervention(P>0.05).3.For the extension and knee peak torque,compared within groups,the two groups were significantly higher than the pre-intervention 4 weeks after the intervention.Statistical significance(P<0.05).Between the two groups,there was no significant difference between the two groups after 4 weeks of intervention(P>0.05).4.For quadriceps flexibility,compared within groups,the two groups were significantly higher than the pre-intervention after 4 weeks of intervention.The difference was statistically significant(P<0.05).Between the two groups,after 4 weeks of intervention,PNF stretching group had a more significant change in the static pulling group,and the difference was statistically significant(P<0.05);Conclusion:the PNF stretching four head muscle and the static pulling four head muscle two kinds of schemes have the curative effect to the patellar tendon terminal disease.PNF tensile muscle four head of the treatment of patellar tendon terminal disease effect is superior to static traction four head muscle.
