The effect of selective rhythmic movements on, hand- foot coordination in girl children with developmental coordination disorder

Development Coordination Disorder (DCD) is occurred when the growth of motor skills delays or some difficulties emerge in performing coordinated movements that is led to the incidence of problems resulting inability to perform in daily tasks. The purpose of this study was to examine the effect of the selective rhythmic movements on hand - foot coordination of children with DCD. In this quasi experimental study, from a total of 475 girl children (6-11 years old) from Shahrekord city (Iran) 30 girl children were selected by the DSD questionnaire and Motor Observation Questionnaire for teachers. Lincolen – Osertsky Motor Proficiency Test was used to measure the dependent variables including hand- foot coordination. At first, subjects participated in pretest and then they were randomly divided into control and experimental groups. Selective Rhythmic Movements were performed by experimental group for eight weeks; three sessions per week and 45 minutes per- session. At the end of the period, both groups participated in the post test. The data were analyzed using independent study t- test. Results showed that at pre-test conditions no significant difference was seen for the means of hand-foot coordination between experimental group vs. control group (P>0.05), but significant difference was observed between groups for post test values (P<0.01). This study showed that selective rhythmic movements are led to hand- foot coordination improvement in DCD children.
