Study Of Balance And Proprioception Training On Ankle Stability Of Patients With Chronic Ankle Instability

Objectives: To observe the injuries of patients with chronic ankle instability(CAI)in terms of pain,joint function,ankle muscle strength,balance and gait;to monitor the therapeutic effects of conventional strength training on CAI patients;to explore the use of conventional muscle strength in training,increase the clinical efficacy of balance and proprioception training for CAI patients.Methods: This study was conducted in the Treatment Center of Sichuan Orthopaedic Hospital.40 patients with unilateral CAI who were diagnosed with medical history,physical signs and necessary auxiliary examinations and met the inclusion and exclusion criteria were collected in this study.Use simple randomization to divide into experimental group and control group.Each group has 20 people.The control group has regular strength training.The experimental group has added balance and proprioception training on the basis of the control group,3 times a week,60 minutes each time,for 6 weeks.The Visual Analogue Scale(VAS),Cumberland Ankle Instability Questionnaire(CAIT),and Relative Peak Torque(RPT)of plantar flexion,dorsiflexion,varus and valgus were recorded before and 6 weeks after the intervention,respectively.Standing time on one leg,swing area of center of gravity in static balance test,standing time on one leg,step length,stride length,stride speed,and stride width in gait test.Research results:(1)There was no statistically significant difference in indicators between the two groups before the intervention(P>0.05);(2)After the 6-week intervention,the VAS scores of the two groups were significantly reduced,and the CAIT scores were significantly improved.The differences were statistically significant(P<0.05);and the VAS score of the experimental group was significantly lower than that of the control group,and the CAIT score was significantly higher than that of the control group.The differences between the groups were statistically significant(P<0.05).(3)After the 6-week intervention,the relative peak torque of plantarflexion,dorsiflexion,varus and valgus in both groups were improved,with statistical significance within the groups(P < 0.05).In addition,the relative peak torques of plantarflexion,dorsiflexion,varus and valgus in the experimental group were significantly higher than those in the control group,and the differences between the two groups were statistically significant.(4)After the 6-week intervention,the standing time on one foot of the two groups of study subjects increased,and the swing area of the center of gravity was significantly reduced.The differences within the group were statistically significant(P<0.05);compared with the control group,the time of standing on one foot in the experimental group was significantly increased,the area of gravity center swing was significantly reduced,and the differences between the groups were statistically significant(P<0.05).(5)After the 6-week intervention,the standing time,step length,stride length,and pace of the two groups of patients were significantly prolonged,and the step width decreased.The differences within the groups were statistically significant(P<0.05);Compared with the control group,the standing time,step length,stride length,and pace of the experimental group were further prolonged,and the step width was significantly reduced,and the differences between the groups were statistically significant(P<0.05).Conclusion: Both 6-week regular strength training and functional exercise with balance and proprioceptive training on the basis of it can reduce the pain degree of CAI patients,improve the joint function,muscle strength,balance and walking ability of the patients,and the combination of balance and proprioceptive training has a more significant effect.
