Abstract:
ObjectiveTo explore the effect of core stability training on dynamic balance and surface electromyography (sEMG) after anterior cruciate ligament reconstruction (ACLR), and to analyze the correlation between balance index and sEMG. MethodsFrom March to December, 2022, 32 patients with ACLR in Yantai Affiliated Hospital of Binzhou Medical University were randomly divided into control group (n = 16) and experimental group (n = 16). The control group accepted routine rehabilitation treatment, and the experimental group added core stability training, for six weeks. They were evaluated with American Hospital for Special Surgery Knee Score (HSS) and International Knee Documentation Committee Knee Score (IKDC), and the dynamic balance function and sEMG were measured before and after treatment, and the correlation between dynamic balance index and root mean square (RMS) of sEMG was analyzed. ResultsAfter treatment, the scores of HSS and IKDC increased significantly in both groups (|Z| > 3.526, |t| > 63.544, P < 0.001), and were better in the experimental group than in the control group (Z = -2.392, t = 2.650, P < 0.05); the length of gait line and single support line increased significantly, the medial-lateral displacement displacement decreased (|t| > 2.368, Z = -3.516, P < 0.05), and they were better in the experimental group than in the control group (|t| > 2.497, Z = -3.091, P < 0.05); the RMS of gluteus maximus and gluteus medius increased in the experimental group (t = -5.900, Z = -2.741, P < 0.01), and were better than those in the control group (t = 3.930, Z = -3.260, P < 0.01). After treatment, the RMS of gluteus maximus and gluteus medius in both groups were positively correlated with gait line length and single support line length, and were negatively correlated with medial-lateral displacement (|r| > 0.502, P < 0.01). ConclusionCore stability training could significantly improve knee joint function and dynamic balance, and enhance the activation of gluteus maximus and gluteus medius. Dynamic balance is highly correlated with sEMG.
