Effect Of Dynamic Balance-related Active Training On Lower Limb Function After Anterior Cruciate Ligament Reconstruction

Objective:At present,the rehabilitation research work of Anterior Cruciate Ligament(ACL)reconstruction mostly focuses on the recovery of local joint function,the lack of ways to improve the overall exercise ability,and the lack of training program design for the purpose of returning to sports.Balance training is a training method in functional rehabilitation,which includes both static and dynamic modes,and dynamic balance training aims to maintain postural stability and improve physical balance ability in exercise mode.At present,dynamic balance training common in clinical research is completed with multiple applied balance instruments,and there are few studies on active training of patient autonomous regulation.In this paper,we analyze the application value of dynamic balance related active training in postoperative rehabilitation training after ACL reconstruction.Methods: In this study,the literature data method was used to collect the relevant experience of dynamic balance training.By randomized controlled experiment,50 patients with anterior cruciate ligament reconstruction who came to the hospital were collected,and the experimental subjects met 12-14 weeks after surgery,and the muscle strength of lower limbs,joint range,and function of daily living activities reached the qualified criteria.Fifty patients were randomly divided into control and experimental groups,with 25 participants each,and the two groups underwent 4 consecutive weeks of rehabilitation training in the same arena.The training content includes routine rehabilitation training such as lower limb muscle strength training and joint activity function training,after which the control group conducts static balance training,and dynamic balance training is introduced in the experimental group.Experimental selection of visual analog scoring method(Visual Analogue Score,VAS),lysholm rating scale to evaluate the treatment effect,using closed single foot standing test,biodex balance system(Biodex Balance System,BBS),Y balance test device(Y-Balance Test,YBT)test static dynamic stability function and stable range,single foot forward jump test to evaluate limb movement after rehabilitation.All test data obtained from the experiment were analyzed and collated,and the experimental data were statistically analyzed using spss23.0 statistical software,and all data were expressed as mean ±standard deviation.Results: The stability evaluation results showed that the test score of the biodex balance system(limits of stability,LOS)exceeded the test group score(51.00 ±8.82,74.44 ± 6.04)than the control group(49.64 ± 10.38,65.40 ± 10.24),indicating that the experimental group had a wider motion range of the affected lower limbs(p=0.00)and a lower risk of falling.The YBT test showed the experimental group(92.32 ±5.36,102.52 ± 5.77)than the control group(92.80 ± 8.36,98.73 ± 6.92),while the test results of bilateral lower limbs showed less distance(4.72 ± 1.48,2.68 ± 1.19)than the control group(4.79 ± 1.99,3.42 ± 1.44),with significant difference between the two groups(p=0.04),indicating that the affected lower limbs had higher stability and the coordination was closer to the healthy lower limbs.However,the standing time in the two groups was not obvious(p=0.11).The results of the lower limb movement ability test showed that the single foot jumped forward,and the bilateral distance(0.20 ±0.05,0.0.13 ± 0.05)was smaller than the control group(0.20 ± 0.06,0.17 ± 0.07).The difference between the two groups was significant(p=0.02),indicating that the movement ability of the lower limbs in the affected side was closer to the fitness level.Functional scale assessments showed similar pain levels and joint function in both groups(p> 0.05).Conclusion: Dynamic balance-related active training showed clear advantages in the improvement of somatic postural control and the stable range of the lower limbs.In terms of motor ability recovery,dynamic balance related active training can provide great power for patients to return to exercise,and has a great impact on the recovery of lower limb function.It is worth introducing in the rehabilitation system framework aiming at the recovery of motor ability.
