Diabetes Melittus (DM) is a disease of great incidence, and one of the main public health problems worldwide, having as complications the deficit in the functional performance of the lower limbs, which can interfere in the maintenance of the balance, besides being a Strong predictor of functional limitations. Individuals affected by diabetes are predisposed to reduce the mobility of the tibial-tarsal joint. Manual therapy is often used for the purpose of improving range of motion. The objective of this study is to evaluate the acute effect of manual therapy on ankle joint mobility in diabetic patients. 40 volunteers, aged 59,35±7,85 years, DM type 2 and tibial-tarsal joint amplitude limitation, of both genders were recruited, divided into two groups: group 1 (Sham: submitted to evaluations and follow up of seven days), and group 2 (intervention: submitted to the evaluations, manipulative manual intervention, with follow up of seven days). The analysis of joint range of motion was acessed by digital goniometry and the static discharge of weight was evaluated by baropodometry computed with open and closed eyes. After tabulation of variables, the Shapiro-Wilk normality test was applied to analyze the distribution. Before a normal and related distribution, ANOVA followed by Tukey post-hoc tests were used. For the variables that presented a non-normal distribution, the Kruskal-Wallis test was used, followed by the Dunn post-hoc test. For the variables that presented a non-normal distribution, the Kruskal-Wallis test was used, followed by the Dunn post-hoc test. The SAS software was used and a significance level of 5% was considered. The results showed an increase in joint range of motion, in the right and left dorsiflexions of the GI between the initial moment and the post-manipulation moments, as well as after seven days of the follow-up. There was also a significant difference between GI when compared to GS in the post and follow-up moments. Regarding the clinical effect of the intervention over time, the intragroup analysis showed that in GS there was no difference between the amplitude of movement registers comparing the pre-intervention moment with the subsequent records (post and follow-up), even for plantar and dorsiflexion flexion movements on both sides. In relation to static plantar weight discharge, there was a change in recorded values for the peak of total foot pressure, on the right and left sides of the GI, between the moments after the immediate intervention and in the measurement 7 days after the manipulative intervention (follow -up), for registration with open eyes. Regarding intra-group comparisons over time (pre, post-intervention and follow-up), a significant difference was observed for the condition amplitude of anteroposterior displacement (DAP) with open eyes of the GI, observing an increase after intervention and reduction in the follow-up. In view of the obtained results, it can be inferred that the acute intervention with manual therapy produces an increase in the joint amplitude of the ankle of diabetic individuals.
