The purpose of the study was to compare dexterity and two-point discrimination of the hand between learning disabled students with dysgraphia and healthy students.</p> <p style="text-align: justify;"><strong>&nbsp; Methods:</strong> Forty-three students with developmental dysgraphia and 55 normal students in grade two to four from special and regular schools participated in this study. Hand dexterity and static/dynamic discriminative touch were assessed via Purdue Pegboard and Two-Point Discriminator respectively.</p> <p style="text-align: justify;"><strong>&nbsp; Results:</strong> Significant differences were found in Purdue Pegboard scores between two groups except in doing the test with the left hand (p<0.05). Purdue Pegboard scores were significantly lower in left-handed children with dysgraphia compared to healthy children (p<0.05). There was no significant difference in dynamic two point discrimination between two groups of children (p>0.05).&nbsp; Static two-point discrimination of the thumb finger was significantly higher in children with dysgraphia (p<0.05).</p> <p style="text-align: justify;"><strong>&nbsp; Conclusion:</strong> Hand dexterity affects handwriting performance in children with dysgraphia. There were no correlations between two-point discrimination and Purdue Pegboard scores of children with dysgraphia. Intervention should focus on other aspects of dexterity rather than sensory components. Hand dominancy also may be a factor influencing hand performance in dysgraphia.&nbsp;</p> Learning disability, dysgraphia, hand, dexterity, two point discrimination. 973 979 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-1-1067&slc_lang=en&sid=1 Naser Havaei naser_havaei@yahoo.com 200319475328460024976 200319475328460024976 No Department of Occupational Therapy, School of Rehabilitation Sciences, Iran University of Medical Sciences, Tehran, Iran.
