dc.description.abstractOsteoarthritis (OA) is a leading cause of disability and loss of function and characterized by pain, reduction of lower limb strength, and abnormal somatosensory function. Centers for Disease Control and Prevention (CDC) research has shown that individuals with arthritis have a higher chance of falls and reduced balance compared to matched healthy individuals. Evidence of the effectiveness of added plantar-surface texture to improve balance has been successful for various younger populations as well as elderly fallers, and clinical populations. However, to date, no studies have systematically investigated the potential benefits of this textured insole intervention, and potential interactions with people with knee OA. Therefore, the purpose of this study was to evaluate textured insoles for individuals with knee OA. Thirty individuals, fifteen with knee osteoarthritis and fifteen healthy, aged-matched controls completed this study and were evaluated on balance as measured by a NeuroCom EquiTest Sensory Organization Test and Motor Control test protocol. Data were analyzed with ANOVA, paired t-test, and independent t-test. The results demonstrated that there were significant improvements in ECF, EORF, VEST, and PMAN when wearing the textured insoles in knee OA group, and in healthy knee group, there were statistically significant improvements in EO-FP, EORF when wearing the textured insoles. Also, EO-SUR, ECF, EORF, VEST, PMAN, and latency were significantly higher and faster for healthy knee controls than for individuals with knee OA. Additionally, there were no interactions between groups and improvements. Thus, it was concluded that although the textured insoles did not produce statistically greater improvements on balance in individuals with knee OA compared to the healthy knee group, individuals with knee OA and healthy controls could improve balance in some tasks with textured insoles. Also, the benefits of this study for the individuals with knee OA are that this may lead to the development of an evidence-based footwear intervention which is noninvasive, simple to use, inexpensive, allows the user for self-management, and has the capacity to reduce the risk of falls, consequentially improving the quality of life.
