Feasibility and Reliability of Functional Mobility Measures in Children With Cri du Chat (5P-) Syndrome.

PURPOSE: To investigate feasibility and reliability of functional mobility measures in children with Cri du Chat syndrome (CdCS).

METHODS

Nine children with CdCS and 9 children with typical development (TD) completed the Timed Up and Go, 5 times sit-to-stand test, Timed Floor to Stand, and 4 Square Step Test. Feasibility was determined using testing time and need for modifications. Intraclass correlation coefficients were calculated for intrarater and interrater reliability.

RESULTS

Children with CdCS required modifications to complete all tests. One child with CdCS completed the 4 Square Step Test. Good reliability was found for both groups.

CONCLUSIONS

The Timed Up and Go, 5 times sit-to-stand test, and Timed Floor to Stand are feasible and reliable tools for children with TD between ages of 5 and 15 years; however, may require modifications to the protocols to be feasible in children with CdCS. The 4 Square Step Test is not a feasible tool for children with CdCS.
