Measurement And Analysis Of Limb Balance Function In Patients With Posterior Circulation Ischemic Stroke

Objective:Analyze the balance function of the non-affected side of the lower extremities of patients with posterior circulation ischemic stroke with the dynamic and static balance instrument,and compare with healthy people,to provide a basis for formulating clinical and rehabilitate treatment plans.Methods:Selected 20 posterior circulation ischemic stroke patients within 2 months whose lesion was unilateral lower extremity.And they were sent to the Department of Rehabilitation Medicine of the First Hospital of Shanxi Medical University from the Department of Neurology and received no rehabilitation trainings during December 2018 to December 2021.A total of 20 healthy subjects matched with the age,height and weight of patients in the case group were selected as the control group.Both lower extremities parameters of healthy people and the study cases were tested and selected with the multi-axis ontology evaluation module in the Pro-Kin254 P dynamic and static balance instrument produced by Tecnobody,Italy.The main observation indexes are Average Force Variation(AFV),Average Trace Error(ATE),Stability Index(SI).The conclusions were draw by analyzing and sorting the data.Results:1.The Average Force Variation(AFV),Average Trace Error(ATE),and Stability Index(SI)of the involved lower extremities with the study group were larger than those of the control group,and the difference was statistically significant(P< 0.05);2.The Average Force Variation(AFV),Average Trace Error(ATE),and Stability Index(SI)of the non-involved lower extremities with the study group were larger than those of the control group,and the difference was statistically significant(P< 0.05);3.The Average Force Variation(AFV),Average Trace Error(ATE),and Stability Index(SI)of the involved lower extremities with the study group were larger than those of the non-involved sides,and the difference was statistically significant(P< 0.05);4.The test parameters of the left lower extremities of the control group were smaller than those of the right lower extremities,and the difference was not statistically significant(P>0.05).Conclusion:1.Patients with posterior circulation ischemic stroke have balance dysfunction in both non-involved and involved lower extremities;2.The balance strategy of the two lower extremities of healthy people is asymmetry,and the proprioception of the lower extremities on the non-dominant side is better than that on the dominant side.There was no significant difference in the balance function of the lower extremities on both sides.
