Abstract:
Objective:To explore the correlation between abdominal muscle morphological parameters and balance func-tion indexes in stroke patients,and to elucidate the mechanism of core muscle groups in postural control,so as to provide evidence-based basis for optimizing the rehabilitation assessment system and intervention strate-gies for balance disorders after stroke.Method:A total of 60 stroke patients admitted to the Rehabilitation Center of the Affiliated Hospital of Shan-dong University of Traditional Chinese Medicine from March to December 2024 were selected.The musculosk-eletal ultrasound diagnostic system was used to quantitatively measure the muscle fiber thickness of the exter-nal abdominal oblique muscle(EO),internal oblique muscle(IO)and transverse abdominis muscle(TrA),and the balance test system was used to collect the center of gravity swing parameters of the patient's stand-ing on both feet with eyes open and closed,including the area of the motion ellipse and the length of the tra-jectory.Correlation analysis was used to evaluate the correlation between abdominal muscle thickness ratio(af-fected side/unaffected side)and thickening rate(contraction/relaxation)and balance parameters,and the predic-tive performance of each abdominal muscle parameter was analyzed by receiver operating characteristic curve(ROC).Result:Bilateral abdominal muscle thickness asymmetry was observed in stroke patients,and the abdominal muscle thickness ratio in patients in the subacute stage was significantly lower than that in the chronic phase(P＜0.05),but the thickening rate was higher(P＜0.05).The abdominal muscle thickness ratio and thickening rate were significantly negatively correlated with the motion elliptical area and exercise length in the open and closed states(r=-0.273—-0.807,P＜0.05).The prediction model analysis showed that the prediction efficien-cy of transverse abdominis(TrA)muscle thickening rate was the best(AUC=0.797),while the combined pre-diction efficiency of internal oblique(IO)muscle and TrA thickening rate was the highest(AUC=0.835).Conclusion:Bilateral abdominal muscle thickness asymmetry occurs in stroke patients and is related to the course of the disease.Abdominal muscle thickness parameters were negatively correlated with balance function,and the thickening rate of TrA and IO could be used as effective predictors to evaluate the balance function of stroke patients,and musculoskeletal ultrasound could be used as a quantitative evaluation tool for abdomi-nal muscle thickness in stroke patients.
