The first step is for the diabetic to lay down on a comfortable surface, such as a sofa or bed, and to close their eyes.
Then the helper (e.g. the family friend) grips one leg at a time, saying whether it is the left or right leg.
The helper then touches the tip of six toes using their index finger for no longer than a second, to be “as light as a feather”.
With each touch, the person with diabetes will say whether they feel the touch on their left or right foot.
