The aim of the study was to analyze postural stability, walking speed and fear of falling in patients with diabetic polyneuropathy (DPN) in order to determine the risk factors for falls, as well as the effect of DPN characteristics as additional factors. A sample of 48 patients with type 2 diabetes and DPN were enrolled in this non-randomized observational study. The patients were divided into two groups of fallers and non-fallers. All subjects underwent evaluation with the Functional Reach Test (FRT), Tinetti Falls Efficacy Scale (Tinetti FES) and 10-Meter Walk Test (10MWT). Neuropathy was quantified with the Michigan Neuropathy Screening Instrument (MNSI, Questionnaire part) and 5.07/10-g Semmes Weinstein monofilament examination (SW-ME). The 10MWT and SW-ME were significantly different between the faller and non-faller groups (p<0.05). Duration of DPN correlated positively with SW-ME (p=0.005) in the faller group. FES showed significant positive correlation with MNSI and negative correlation with 10MWT in the non-faller group. Logistic regression analysis revealed that SW-ME was significantly associated with the probability of falling (p=0.0076; OR=1.378). Study results suggested that the loss of protective sensitivity of foot could be a risk factor for falls in people suffering from type 2 diabetes.
