Objective: One of the most prevalent sensory problems in cerebral palsy is Astereognosis which has special importance in daily manual functions. The purpose of this study was to determine the level of hand stereognosis using common objects and geometric shapes in children with spastic hemiplegia and diplegia.
Materials & Methods: In this cross sectional study, 20 children with cerebral palsy between 3-6 years old (9 males, 11 females) with mean age (hemiplegya: 55months, diplegya: 57months) were selected through nonrandomized convinience sampling referd to Occupational Therapy centers of Shahid Beheshti University of Medical Sciences. Stereognosis was evaluated using geometric shapes (square, circle, rectangular, triangle) and common objects (pencil, key, coin, nail, teaspoon and screw) and test special board. The data were analyzed by Mixed Analysis of Variance and Regression statistical tests.
Results: There was no significant regression between common objects stereognosis score and age in hemiplegic childrenbut this regression was significant for stereognosis score of geometric shapes (P=0.027). There was no significant regression between stereognosis score of common objects and geometric shapes in diplegic children. The Main effects of gender was not significant in stereognosis of children with spastic hemiplegia and diplegia, also main effects of hand were not significant in two groups.
Conclusion: There was no significant difference between stereognosis of affected and unaffected hand in hemiplegic childrenand between right and left hands in diplegic children. Also There was no significant regression between age and stereognosis score of geometric shapes in diplegic children .
