ABSTRACT
Background: The normal ability to distinguish two points from one is the two point discrimination sense. Two point discrimination is extensively used clinically in evaluating injuries to the nerves that supply hands & to assess outcome of surgical manipulations such as digital replantation, skin grafting and peripheral nerve repairs. Normative values are extremely useful in interpreting test result from sensory assessments.
Method: A total of 100 patients (50 males & 50females) are assessed to find out normative values using asthesiometer to assess tactile sensitivity in normal individuals, ranging from age 40-59 years. The normative values were calculated on five digits of both hand, midpalm, thenar, hypothenar & dorsum of hand regions.
Results: The two point discrimination values vary according to different regions of hand. According to the study values for digits are between range of 3-5mm while for other hand regions they are like for midpalm region 12-13mm, for thenar 11-12mm, for hypothenar 11-13mm & for dorsum of hand 15-17mm.
Conclusion: The study concluded that fingertips were more sensitive than midpalm, thenar, hypothenar regions & dorsum of hand & women have more two point discrimination ability than men.
Key words: Two point discrimination, Hand
