The goal of this clinical trial is to learn if foot-ankle exercise can prevent diabetic foot ulcer incidence in patient with diabetes neuropathy. It will also learn about the effect of foot-ankle exercise on improvement of diabetes neuropathy severity, glycemic control, brain-derived neurotropic factor, walking speed, foot ankle range of motion, callus. The main questions it aims to answer are:
* Does foot-ankle exercise lower the number of diabetic ulcer incidence
* Does foot-ankle exercise lower the diabetes neuropathy severity
* Does foot-ankle exercise improve glycemic control
* Does foot-ankle exercise improve brain-derived neurotrophic factor
* Does foot-ankle exercise improve walking speed
* Does foot-ankle exercise improve foot ankle range of motion
* Does foot-ankle exercise lower the number of callus incidence
