Two-Point Discrimination Test

The Two-Point Discrimination Test assesses how well your skin can distinguish two separate points touched simultaneously. A practitioner uses a device with two small points or fine tips and gradually adjusts the distance between them, touching your skin to identify the shortest distance at which you perceive two distinct sensations. This test helps evaluate nerve function and skin sensitivity, providing insight into the health of sensory nerves. Better discrimination indicates more precise nerve ending functioning, while difficulty can suggest nerve damage or sensory impairments.
