Background and aim:One of the common learning disability is dysgraphia that interferes academic progressive and/or activity of daily living in children.The aim of this study was comparative assessment of hand sensory - motor skills in 9 -11 ages
Materials and Methods: 20 dysgraphia and 40 normal children were selected for comparison. Participants were evaluated by Smmes-Weinstein Monofilaments (SWMs), The Minnesota Manual Hand Dexterity Test (MMDT), Power Grip Test with Dynamometer (GS), Pinch Strength with Pinch Guage (thumb to middle-thumb to index test) and Minnesota Hand Writing Test (MHT).They were divided into A (dysgraphia) and B (normal)Groups. In this research, dominant hand was right. All Data were analyzed by T-Test and Chi – square Tests with SPSS version13.
Results:The study showed that sensory-motor skills hand writing in dysgraphia children were significantly lower than normal children. There was a significant relationship between tactile threshold and dysgraphia. (P<0.05).In children with dysgraphia, the tactile threshold was high. Hand dexterity was significantly poorer in A group than B group. (P<0.05). Grip strength and Pinch strength were significantly poorer in A group than B group. (P<0.05 for G.S and P<0.05 for P.S). There was a significant relationship between handwriting skill and dysgraphia. (P<0.05).
Conclusion: Findings of this study, could be created in the mind of experts and therapists that perhaps with determination of suitable sensory-motor evaluations of precise Prpcedure to prevent and treat children who have dysgraphia problem,
