| Objective To investigate the balance function in those patients with knee osteoarthritis (KOA)and its influential factors.Methods From Dec 2014 to Sep 2017, 30 patients with unilateral KOA hospitalized in our hospital were collected as the study objectives. Their balance function was measured with balance performance monitor, and the finished time and average trace error (ATE)of measurement between the involved side and the uninvolved side was detected and compared. Then the body mass index (BMI), Kellgren-Lawrance grade, pain index and American knee society score (KSS) of all patients were collected, and multivariate regression analysis was used to investigate the effects of these indexes on balance function.Results Comparison of balance indexes between the involved side and the uninvolved side showed that, the ATE value of involved side (40.77±23.85)% was significantly higher than that of uninvolved side (46.63±25.30)% (t=-2.299,P<0.05).Multivariate regression analysis revealed that, results of KSS had statistical significance in the average back-and-forth motion speed (t=-2.593, P<0.05) and trace length of postural sway (t=-2.178, P<0.05) when eyes opening, with ratios of explained variation of 19% and 15%, respectively.Whereas the pain index had statistical significance in the trace length ratio of eye closing to eye opening (length ratio of Romberg value) (t=-2.641, P<0.05), with ratio of explained variation of 20%.Conclusion The balance function disorder is presentin those patients with KOA, and the joint pain index and KSS of involved sideis of important significance for evaluation of the balance function of KOA patients. |
