| Objective: Ankle sprain has a huge impact on different groups of people,athletes stop training,the elderly fall fracture,therefore,the prevention of ankle sprain has great social significance,and this experiment mainly for chronic ankle instability implementation effect of kinesio Taping stop motion and different time points of kinematics,dynamics,electrophysiological study,explore the effect of kinesio Taping of chronic ankle instability ankle protection effect and short timeliness,thus to prevent the ankle injury,intramuscular effects of patch greater value to provide theoretical basis and practical reference.Methods: This study included in the standard of chronic ankle instability 15 subjects,using motion capture system,multi-dimensional,surface electromyograph synchronization acquisition methods of subjects in taping before,the moment after taping and after 20 minutes,40 minutes,60 minutes to stop action on the phase of the ankle joint and the direction Angle,angular velocity and peak torque,the ground reaction force and the corresponding time,major muscles around the ankle root-mean-square amplitude and integral electrical values such as biological indicators.After the collected data were sorted out in Excel,SPSS 20.0 statistical software was used to conduct single-factor repeated measurement analysis of variance for the data.All the indexes were statistically significant(P<0.05)and extremely significant(P<0.01).Results: kinematics:(1)There was no significant difference in eversion angle at the time of landing(P>0.05),but plantar flexion angle at the time of landing increased significantly(P<0.05),and there was no significant difference in the other time points(P>0.05);(2)except that the maximum dorsiflexion angle increased significantly 20 minutes after taping(P<0.05),there was no significant difference in other time points(P>0.05),but there was no significant difference in the maximum plantar flexion angle,maximum inversion angle and maximum eversion angle at different time points after taping(P>0.05);(3)There was no significant difference in the amplitude of ankle varus and dorsiflexion at different time points after taping(P>0.05).Except for the maximum varus angular velocity at 20 minutes after taping was significantly lower than that before taping(P<0.05),there was no significant difference in the maximum angular velocity in other directions(P>0.05).Dynamics:(1)The peak value of vertical GRF immediately after ligation was significantly higher than that before ligation(P<0.05),and there was no significant difference at other time points(P>0.05),while the peak value of horizontal GRF had no significant difference compared with that before taping(P<0.05).The corresponding peak time of horizontal GRF was significantly longer than that at 60 minutes after ligation(P<0.05),and there was no significant difference at other time points(P>0.05)There was no significant difference in other time points(P>0.05);(2)The peak of dorsiflexion torque at 20 minutes after taping was significantly lower than that before taping(P<0.05),and there was no significant difference at other time points(P>0.05).The peak of ankle plantar flexion torque,inversion and eversion torque had no significant difference at all time points after taping(P>0.05).Relectrophysiology:(1)The root mean square amplitude of peroneus longus(PL)at 60 minutes after taping was significantly lower than that before ligation(P<0.05),and there was no significant difference at other time points compared with that before taping,while the root mean square amplitude of anterior tibialis(TA),lateral gastrocnemius(LG),medial gastrocnemius(LM)and soleus(SM)at each time point after taping had no significant difference compared with that before taping(P>0.05);(2)The integral EMG values of TA,PL,LG,MG and SM at different time points after taping were not significantly different from those before taping(P>0.05).(3)The contribution rate of PL muscle at 40 minutes after taping was significantly lower than that before taping(P<0.05),and there was no significant difference at other time points(P>0.05);There was no significant difference in muscle contribution rate of TA,LG,MG and SM at different time points after taping(P>0.05).Conclusion:(1)The time-effective time of ankle joint binding in CAI patients was 0-20 minutes,lasting to 60 minutes,but the study did not know the failure time.(2)The results showed that 20 minutes after taping,the protective effect on ankle inversion was increased,which showed that the speed of ankle inversion was decreased,and the time of nerve muscle varus was significantly prolonged.(3)After 40 minutes and 60 minutes,the ankle joint still had a certain protective effect,mainly for the peroneus longus muscle contribution rate decreased,the ankle joint load rate decreased,but for the ankle inversion protection decreased. |
