Abstract
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,

Abstract
Background and aim: The ability to maintain upright stance is essential in gait and initiation of voluntary movements that are vital not only for sport but also for activity of daily living .Lateral ankle sprains are common in athletes and are most prevalent in jumping sports such as volleyball , football and basketball .Although these injuries are common after direct contact. It may occur in non contact mechanism such as landing from a jump. Neuromuscular control plays a major role in dynamic joint stability. Most of ankle joint injuries occur in jump-landing task and at the end of sport activitiesparticularly when the athlete is fatigued. Our purpose was to evaluate the effects of ankle muscle fatigue on dynamic postural stability in jump landing task.
Material and methods: Twenty two healthy women athletes (age:22.8±1.7 years, height:160.3±4.9 cm and weight:56.2±5.8 kg) volunteered to participate in this study .Two test sessions were done with a rest period of one week between them . During each session, effect of one group of ankle muscles (sagital or frontal movers) on dynamic postural stability was assessed. Postural stability was evaluated for 5 seconds after landing on force plate by postural stability indices ( Medial/Lateral, Anterior/Posterior, Vertical and Dynamic Postural Stability Indices) before and after isokinetic fatigue of ankle muscles.
Results: The finding indicate significant increase in all stability indices after isokinetic fatigue of ankle muscles (p<0.05).
Conclusion:These results indicate that isokinetic fatigue of ankle muscles significantly decrease postural control ability in healthy women athlete.
