An Immediate Effect Of Different Joint Intramuscular Patches On Balance And Gait In Patients With Patellar Pain Syndrome

Background: Patellar pain syndrome is a common musculoskeletal disorder that is very common in the general population,especially young adults and adolescent athletes who participate in sports such as jumping and spinning.In recent years,intramuscular patches have been widely used in competitive sports,sports medicine and rehabilitation medicine.There have been many studies on the treatment of PFPS with intramuscular patches at home and abroad,most of which are applied to the knee joint,and a small number of foreign studies have applied the kinesio taping to the hip joint of PFPS patients,and there are fewer domestic related studies than abroad.At the same time,some scholars have found that kinesio taping cannot improve the balance and gait of PFPS patients.Therefore,this study aimed to investigate the effect of hip and knee monoarticular kinesio taping on immediate gait and balance in patients with PFPS,and whether joint hip-knee kinesio taping produces better results.Objective: To investigate the effect of lower limb hip and knee monoarticular taping on immediate balance and gait in patients with patellar pain syndrome,to compare whether hip-knee joint taping produces better therapeutic effects。The effect of different tensions on the results of this experiment was also compared by comfort taping.Methods: Sixteen female patients with patellar pain syndrome were randomly subjected to 4taping groups according to the diagnostic criteria of patellar pain syndrome,including blank control group,knee group,hip group,hip knee group,hip knee group,and hip-knee placebo group.Immediately after each taping,Italian BTS P-Walk plantar pressure,TUG test and star shift balance test were used for immediate dynamic and static balance and gait test,and one-way ANOVA was used for intra-group comparison.Results:Comparison of different parts of the application:(1)Open-eye and closed-eye static balance: single-applied knee(P < 0.05),hip and knee double-applied(P < 0.01)open-eye and closed-eye static balance indices(COP transverse axis distance,COP longitudinal axis distance,COP distance,COP area,sway speed)were statistically different compared to the blank group;there was no significant difference between single-applied knee and single-applied hip comparison(P > 0.05);There was no significant difference(P > 0.05)between hip and knee double taping and single knee taping,and only COP transverse axis distance,COP distance,and rocking speed were significantly different(P < 0.05)compared with single hip taping.(2)Dynamic balance: The forward extension distance of SEBT test: there were significant differences between single knee taping(P<0.05),single hip taping(P<0.05)and hip knee double joint taping(P<0.01)compared with blank group,no significant difference between single knee and single hip(P>0.05),and no significant difference between hip and knee double joint taping and single knee and single hip(P>0.05).The comprehensive values of lower limb on the affected side: single knee(P<0.05),single hip(P<0.05),hip and knee double joint taping(P<0.01)were statistically different compared with the blank group,and there were no significant differences between single knee,single hip and hip knee and hip and knee double joint taping(P>0.05).(3)Gait: There was a statistically significant difference between the single knee taping,single hip taping,and hip-knee double-joint taping step lengths compared with the blank group(P <0.05);there was a statistically significant difference between the hip-knee double-joint taping and the blank group step length(P < 0.01),and there was no significant difference between the single knee and single hip taping(P > 0.05);the single knee taping,single hip taping,and hip-knee double-joint taping prolonged the weight-bearing time of the affected lower limb and reduced the step width compared with the blank group However,there was no statistical difference(P>0.05);the walking cycle time and TUG test time were reduced(P<0.05)and the walking speed was increased(P<0.05);meanwhile,there was no significant difference(P>0.05)in the comparison of single hip taping and single knee taping,and the joint taping of hip and knee did not have better effect on improving gait(P>0.05).Comparison of different tensile bonding:(1)Static balance between open eyes and closed eyes: the static balance between open and closed eyes(COP horizontal axis distance,COP vertical axis distance,COP distance,COP area,swing speed)after comfort and patching were better than those in the blank group,but there was no significant significance(P>0.05),and the comparison between the placebo group and hip-knee double joint taping was statistically significant(P<0.01).(2)Dynamic balance: the comprehensive values of extension distance and lower limb on the affected side of the placebo group were better than those in the blank group,but there was no significant significance(P>0.05),and the comparison between the placebo group and hip-knee double joint taping was statistically significant(P<0.01).(3)Gait: Compared with the blank group,the step length,stride length,stride speed,support time,walking cycle timing,and TUG test time were all improved in the placebo group compared with the blank group,but there was no significant significance(P>0.05),and compared with hip and knee double joint taping,the step length and stride speed were increased,TUG test time and the walking cycle timing were reduced(P<0.05),the stride increased and support phase time on the affected side,the step width was reduced,but not statistically significant(P>0.05).Conclusions:(1)Knee taping improves immediate static and dynamic balance and gait in PFPS;(2)Hip taping had no significant effect on improving static balance in patients with PFPS,but it could improve immediate homeostasis and gait in patients with PFPS.(3)Compared with single-hip and single-knee joint taping,hip-knee joint taping had no significant effect on improving immediate balance and gait in patients with PFPS.(4)Compared to the natural tension,the 25% tension taping group had a better effect on improving the immediate balance of PFPS patients;it had a significant effect on improving immediate stride length,stride speed,walking cycle timing,and TUG test time,and no significant effect on improving immediate stride length,stride width,and affected side support phase time.
