To validate the movement problems in daily life in girls with Turner's Syndrome (TS), reported by teachers, parents and the girls themselves. We examined whether these girls have an impaired motor ability and a specific pattern of motor impairment. As TS phenotypes are characterised by a particular profile of normal verbal IQ and lowered PIQ, we investigated whether there is a significant correlation between the intelligence scores and motor performance scores. Fifteen girls with TS (ages 5.8-12.5 yr.) of which nine girls had 45 XO-type and six girls mosaic-karyotype, were individually tested on the MABC and the WISC-RN. Mean percentile score of the Movement ABC was 2.93 (range 1-8). Based on the Total score of the MABC, none of the girls with TS fell into the normal range; 5 subjects (33%) were classified as at risk, 10 (67%) as impaired. Girls with TS made more errors and needed more time across all items tested and no specific profile of impairment was observed. No significant correlation between intelligence scores and motor performance scores was observed. The results clearly demonstrate that girls with TS indeed suffer from a significant general motor impairment. The motor problems apparently cannot be attributed to problems in the cognitive domain.
