two-point discrimination

Two-pointdiscrimination The patient closes his eyes and stimulates the skin with two separate feet. If the patient has two feelings, the distance between the two feet is shortened until the patient feels a little. The sensitivity of the two parts of the body to the two points is different, with the tip of the tongue, the nose and the fingers being the most obvious, and the proximal extremities and the trunk are the worst. The examiner should pay attention to the strength of the patient's skin when using a separate double foot gauge to prevent the patient from getting a puncture.
