title: Poorly coordinated children: a survey of 95 cases.
abstract: Screening of 717 5-year-olds and 757 7-year-olds, found 55 of the former and 77 of the latter possibly to be poorly coordinated. Further diagnostic testing with the McCarthy Motor Scales confirmed the problem in a total of 95 children, a prevalence of 6.4%. Neurological examination showed 43% of the 5-year-olds and 21% of the 7-year-olds to have choreiform movements. Of the total 95, proprioception was abnormal in 40%, but abnormal muscle tone present in only 4%. An increased prevalence of hearing loss and obesity and a history of developmental delays was found. Low birth weights, prematurity, post-maturity and perinatal problems were significantly associated with poor coordination. Socioeconomic status was not a significant factor. The difficulties of testing and measuring poor coordination and the need for more precise measures are discussed. Follow-up of at risk children at age 5 with tests of motor coordination is recommended.
