The two-point discrimination (2PD) test is the most frequently used test for the assessment of the sensory outcome after nerve repair. It tests the ability to discern that two nearby objects touching the skin are truly two distinct points, not one. It relies on the ability and/or willingness of the patient to subjectively report what he/she is feeling and should be completed with the patient’s eyes closed. The therapist may alternate randomly between touching the patient with one point or with two points on the area being tested. The simulated activity allows the user to test using desired tools provided and thereby listening to the respective response.
