FUNCTIONAL ANALYSIS OF GAIT WITH INSOLE USE IN DIABETIC FEMALE RATS: A CROSS-SECTIONAL STUDY

ABSTRACT Introduction: Diabetes mellitus is a chronic disease that is characterized by causing damage to the peripheral nervous system, generating sensory and motor changes. Objective: This study aims at analyzing the impact of the use of different orthotic insoles on the gait of diabetic female rats. Methods: Twenty-six female Wistar rats were randomly divided into the Control and Diabetic groups. The mechanical sensitivity test was performed manually on the surface of the animals' hind paws using the von Frey test. The functional evaluation was carried out on an adapted platform where the animals were stimulated to walk in order to capture images of the ventral region for measurements of the right and left hind paws. After the images were collected they were processed using Kinovea software version 0.8.27 to assess: stride distance, time, speed and acceleration. Results: There was a reduction in the weight of the animals in the Diabetic Group (p = 0.0018), associated with hyperglycemia (p =
