A Study Of The Effects Of Two Types Of Balance Training On The Stability Of Patients With Functional Ankle Instability

Research purposes:To investigate the effect of 6 weeks of POSTUROMED balancer training versus BOSU ball training on the stability of people with functional ankle instability(FAI).1.Whether there is an improvement in stability in people with FAI with POSTUROMED balancer training versus BOSU ball training;2.To compare the effect of 6 weeks of POSTUROMED balancer training versus BOSU ball training on the stability of FAI whether differences exist.Research method:A total of 54 patients with functional ankle instability who met the requirements were selected for this study and randomly grouped into the POSTUROMED balancer group and the BOSU ball group.In the balancer group,27 patients were trained with the POSTUROMED balancer and in the BOSU ball group,27 patients were trained with the BOSU ball.Both groups were trained for 6 weeks,3 times/week for 30 min each time.active ankle mobility,muscle strength,standing time on one foot with eyes closed,balance error score,Y balance test,BIODEX open-eye and closed-eye postural stability and unipedal postural stability,stability of the plantar pressure testing system,and Cumberland ankle instability scale were assessed before and after training.The data were processed and statistically analysed using SPSS 26.0statistical software.Research results:1.Range of motion: After 6 weeks of training,there were significant differences in ankle AROM in the balance instrument group: plantar flexion,inversion and valgus compared to pre-training(P<0.05)and very significant differences in dorsiflexion compared to pre-training(P<0.01);in the BOSU ball group: dorsiflexion and plantar flexion compared to pre-training(P<0.05)and inversion and valgus compared to pre-training(P< 0.01).2.Muscle strength: there were highly significant differences in ankle dorsiflexion,plantarflexion,inversion and valgus muscle strength in the balance apparatus and BOSU ball groups compared to pre-training(p< 0.01).3.Balance error score: After 6 weeks of training,there was a highly significant improvement in the balance error score(BESS)in the balance meter group and the BOSU ball group(P<0.01);there was a significant difference in BESS between the two groups(P<0.05).4.Closed-eye single-leg stance results: After 6 weeks of training,the length of time standing on one foot with eyes closed was significantly higher in both the balancer group and the BOSU ball group compared to the pre-training period(p<0.01).5.Y balance test results: after training,there were highly significant differences in the anterolateral,posterolateral,posteromedial and composite scores between the balancer and BOSU ball groups(p<0.01);when comparing the results between the balancer and BOSU ball groups,there were significant differences in the reach distance in the posterolateral direction and highly significant statistical differences in the reach distance and composite score in the posteromedial direction(p<0.01).6.BIODEX balance assessment system: 1.Bipedal eye opening: after 6 weeks of training,there was a highly significant improvement in both OSI and MLSI in the balancer group(p<0.01)and a highly significant difference in OSI in the BOSU ball group(p<0.01);after 6 weeks of training,there was a highly significant statistical difference in MLSI in the balancer group compared to the BOSU ball group(p<0.05).2.Closed eyes: At the end of 6 weeks of training,there was a highly significant improvement in OSI,APSI and MLSI in the balancer group(p<0.01)and a highly statistically significant difference in OSI and APSI in the BOSU ball group(p<0.01).After 6 weeks of training,there was a significant difference between the two groups in OSI,APSI and MLSI(P<0.05).3.Single foot eye opening: after 6 weeks of training,there was a highly significant improvement in OSI,APSI and MLSI in both groups(P<0.01);a comparison between groups revealed a significant difference in OSI and MLSI between the two groups(P<0.05).7.Plantar pressure testing system: 1.Dynamic walking: after 6 weeks of training,there was a significant improvement in the centre of pressure link/footprint length ratio in both the balance meter group and the BOSU ball group(P<0.05);after training,there was a significant difference in the ratio between the groups(P<0.05).2.Static: single footed eye opening: compared to 6 weeks before training,there was a highly significant improvement in ball length and mean speed in the balance meter group(P< 0.01)and the BOSU ball group showed a significant improvement in ball length and mean velocity(P<0.05);after training,there was a significant difference in ball length and mean velocity in the balancer group compared to the BOSU ball group(P<0.05).Single-legged closed eyes: there was a highly significant improvement in ball length and mean velocity in both the Balanced Instrument and BOSU ball groups compared to 6 weeks prior to training(p<0.01);after training,there was a statistically significant difference in ball length and mean velocity in the Balanced Instrument group compared to the BOSU ball group(p<0.05).8.Cumberland Ankle Instability Scale(CAIT): After 6 weeks of training,there was a highly significant improvement in the CAIT scores in both the balance meter group and the BOSU ball group(p<0.01).Research conclusions:1.6 weeks of POSTUROMED balance training and BOSU ball training can improve ankle mobility and muscle strength of the peri-ankle muscles and help improve ankle function.2.6 weeks of POSTUROMED balance training and BOSU ball training had a positive effect on improving the dynamic and static stability of FAI patients,and the effect of balance training was relatively better than that of BOSU ball balance training.3.6 weeks of POSTUROMED balancer training and BOSU ball training improved CAIT in people with functional ankle instability and improved the sense of self-stabilisation of the ankle joint,with no significant difference between the two groups.
