Correlation between Postural Stability and Functional Mobility in Patients with Knee Osteoarthritis

Abstract

Background: Osteoarthritis (OA) is a degenerative joint disorder caused by progressive erosion of articular cartilage. The joint which is commonly affected is theknee joint. Patient with knee OA has increasing pain with decreasing postural stability, and may cause decrease infunctional mobility of the body. The aim of this study was to analyze the correlation between stability and mobility in patients with knee OA. Methods: A cross sectional study was performed to 43 patients from the Rheumatology Clinic ofDr. Hasan Sadikin General Hospital, Bandung, during September−October 2013. The 'Timed Up and Go' (TUG) test and stabillometric platform examination were performed to analyze the mobility and stability in subjects. The data were analyzed with Spearman's Correlation. Results: Four subjects (9.30%) had normal functional mobility, 31 subjects (72.09%) had good mobility and need no help of others in their activities, and 8 subjects (18.60%) had problems and could not stand and walk without help. This study also found 39 subjects (90.69%) had high risk of fall. The p value were 0.005 for correlation between knee OA and lateral static postural stability, 0.

The Effect of Lateral Wedge Insole on Gait Variability Assessed Using Wearable Sensors in Patients with Medial Compartment Knee Osteoarthritis

“…Tus, understanding ambulatory dysfunction and its management are important for preventing fall events due to knee OA in daily clinical practice. Knee OA often presents the lack of postural stability with knee instability during routine activities [7,8] and was correlated with balance function which can predict fall events [9]. Gait is the regular and repetitive movement of the lower limbs; however, pathological OA patients with a lack of postural control present irregular motion of their limbs involuntarily [10,11].…”
