The most used tool assessment was Movement Assessment Battery for Children (MABC); in a total of 22 studies, 12 of them used the 5th percentile cut-off, while 10 of them used the 15th percentile. The Developmental Coordination Disorder Questionnaire (DCDQ); was the second most used assessment tool in a total of 7 studies. Two studies used Touwen Infant Neurological Examination; 1 used Bruininks–Oseretsky Test of Motor Proficiency; and 1 study only referred to use the Diagnostic and Statistical Manual of Mental Disorders.
