| Objective: To explore the effect of functional strength training on functional recovery after ACL reconstruction,and to provide a scientific clinical basis for the application of functional strength training.Object and method: From May 2019 to August 2020,20 ACL reconstruction patients after 1 month postoperative were recruited and were met the inclusion standards.According to the measurement of the enroll order,20 patients were randomly divided into the experimental group and the control group,each 10 patients.The experimental group received functional strength training and routine training,and the control group received the routine training.The experimental group underwent 8weeks of continuous training,the first 2 weeks of routine rehabilitation training,and the last 6 weeks of functional strength training,3 times a week,1.5 hours per time.The control group received regular training for 8 weeks,3 times per week,1.5 hours per time.The training was conducted under the guidance of a sports therapist,and the evaluation was conducted at the before and after 8 week intervention,Theevaluation contents included Lysholm ratings;Range of motion（active knee flexion Angle）;Balance ability of standing on one leg（eyes open for more than 30 seconds qualified）and Y-Balance dynamic balance assessment;Raise the back foot and squat for 1RM.The circumference of the affected thigh（take the circumference of the leg 10 cm above the patella）.Data were analyzed by SPSS19.0 statistical software,P<0.05 was considered statistically significant.Results: Before training,there were no significant differences in Lysholm score,range of motion,Y-balance dynamic Balance test score,1RM strength of rear foot elevation and leg squat and leg circumference between 2 groups（P > 0.05）.After intervention,Lysholm score in both groups was significantly improved,and Lysholm score in the experimental group（88.4±6.1）was better than that in the control group（75.4 ±2.5）after training,with significant statistical significance（P <0.01）;After training,the active buckling Angle of the experimental group（129.3±4.4°）was better than that of the control group（117.5±4.7°）,and the comparison between the groups was statistically significant（P<0.01）;After training,the standing time on one leg of the experimental group（60.8±11.0 seconds）was better than that of the control group（39.4±2.8 seconds）,and the comparison between the groups was statistically significant（P < 0.01）;After training,the Y-balance composite score of the experimental group（71.4±2.7）was better than that of the control group（61.4±4.7）,and the inter-group comparison was statistically significant（P<0.01）;After training,the experiment group（58.0±7.8kg）was better than the control group（40.0±8.1kg）,and the comparison between the groups was statistically significant（P<0.01）;After training,the leg circumference of the affected side in the experimental group（44.0±2.0cm）was better than that in the control group（41.4±2.5cm）,and the comparison between the groups was statistically significant（P<0.01）.Conclusion:Functional strength training and routine training can accelerate the recovery of lower limb functional ability（including step up and down,gait,pain,knee active flexion Angle,strength,one-leg balance ability）of basketball players after anterior cruciate ligament reconstruction. |
