The purpose of this study was to analyze the range of movement of the ankle and the vertical ground reaction force involved in gait among diabetic patients with and without peripheral neuropathy. 36 individuals were divided into three groups: Control group–CG: 10 individuals without diabetes, Diabetic group–DG: 10 individuals with diabetes without peripheral neuropathy and Neuropathy, and Diabetic neuropathic group–DNG: 16 individuals with diabetes and peripheral diabetic neuropathy. Gait-AMTI® OR6/6m and range of tibiotarsal joint movement–System Vicom 640® was carried out in all the participants. The first and second vertical ground reaction force peaks were statistically higher in the neuropathy group, and the range of ankle motion was lower in the Diabetes and Neuropathy groups. The range of movement of the tibiotarsal joint is lower in diabetics, regardless of the presence or absence of peripheral neuropathy, and diabetics with peripheral neuropathy show an increase in the first and second vertical ground reaction force peaks during walking.
