Abstract:

Background: Dysgraphia as a problem with handwriting, affects student&rsquo;s performance in school activities and participation. 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. &nbsp; Methods: 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. &nbsp; Results: 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). &nbsp; Conclusion: 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;
