Although two-point testing is commonly used clinically, evidence accumulated from many research studies indicates that 2PD is a flawed measure of tactile spatial acuity. Research studies have shown that the two-point test may have low sensitivity, failing to detect or underestimating sensory deficits, that it only poorly tracks recovery of function following nerve injury and repair, that it has poor test-retest reliability, and that it fails to correlate with validated measures of tacti…
