Purpose:
This case study provides information regarding the motor development and health-related fitness level of a female with 47,XXX. The Movement Assessment Battery for Children-Second Edition (MABC-2) and the Test of Gross Motor Development-Second Edition (TGMD-2) batteries were used to assess motor competence and gross motor development, respectively. Cardiorespiratory, muscular fitness, and flexibility were assessed by means of field-based tests. Two groups of children developing typically were used for comparison purposes.
Summary Of Key Points:
Results from the MABC-2 indicated that the participant was placed in the 37th percentile, whereas the comparison group was placed in the 68th percentile. The participant scored above the 50th percentile in the TGMD-2 and showed lower fitness values than those in the comparison group.
Recommendations For Clinical Practice:
Contrary to what is generally expected, supernumerary 47,XXX does not have to negatively impact motor competence, although a low health-related physical fitness can be present.
