Effect Of Water-based Walking Exercise On Balance And Walking Functions Of Early Patients Following ACL Reconstruction

Objective: To apply water-based walking exercise to the early rehabilitation program after ACLR,and to observe the effects of water-based walking exercise on knee balance,proprioception,walking function and postoperative swelling in ACLR patients,and to provide reference for the improvement of the rehabilitation program after ACLR surgery.Methods: Thirty-eight patients with ACLR from December 2021 to December2022 were selected from the rehabilitation medicine department of Shenzhen Occupational Disease Control Hospital.The patients were randomly divided into water-based walking exercise group and conventional rehabilitation training group for 4weeks,and the indexes related to lower limb balance and walking function were collected before and after the intervention,respectively.SPSS25.0 software was used to analyze the data,and paired sample t-test was used to compare the index data before and after treatment between the two groups,and independent sample t-test was used to compare between the groups,and the significance level was P < 0.05.Results:(1)the passive angular formation errors of 30° and 60° in both groups were significantly reduced compared with those before treatment in the group(P<0.05);and the passive angular formation errors in the observation group were significantly smaller than those in the control group after treatment(P<0.05);(2)the COP ellipse area of the plantar foot standing in both groups was significantly reduced compared with that before treatment in the group(P<0.05),and compared with that between groups The difference was not statistically significant(P > 0.05);(3)the plantar COP ellipse area of the affected side of the observation group was higher than that of the healthy side after treatment,but the difference was not statistically significant(P > 0.05);the plantar COP ellipse area of the affected side of the control group was higher than that of the healthy side(P < 0.05).The difference between groups: the plantar COP ellipse area on the affected side of the observation group was significantly lower than that of the control group(P < 0.05).(4)After treatment,the length of the single support phase on the affected side was shorter than that on the healthy side in both the observation and control groups(P < 0.05);compared with the control group,the difference between the length of the single support phase on the affected side and that on the healthy side was smaller in the observation group(P < 0.05);(5)Holden’s walking function classification was analyzed using the Mann-Whitney U test in both groups.was analyzed.The post-treatment grade scores of the observation group and the control group were greater than those before treatment,and the differences were statistically significant.The results before and after treatment between groups showed that the difference in scores between the two groups was statistically significant after treatment,and the treatment effect in the observation group was better than that in the control group;(6)the Lysholm score of knee function was significantly greater than that before treatment in the group(P<0.05)and the Lysholm score in the observation group after treatment was significantly greater than that in the control group,and the difference was statistically significant(P<0.05);(7)the midline patellar swelling value in both groups was significantly reduced compared with that in the group before treatment(P<0.05),and the midline patellar swelling value in the observation group after treatment was significantly smaller than that in the control group,and the difference was statistically significant(P<0.05)Conclusions:(1)water-based walking exercise can significantly improve the proprioceptive function and single-leg standing balance,and enhance the stability and postural control of lower limbs in early ACLR patients,but the effect of improving the standing balance of both feet is not better than that of conventional rehabilitation treatment alone;(2)water-based walking exercise combined with conventional rehabilitation treatment can significantly improve the temporal parameters of walking cycle in early ACLR patients and promote the recovery of normal(2)water-based walking exercise combined with conventional rehabilitation therapy significantly improved the temporal parameters of the walking cycle in early ACLR patients and promoted the recovery of normal gait patterns;(3)water walking training combined with conventional rehabilitation therapy significantly improved the swelling of the knee joint in early ACLR patients.
