This multiple-case study investigated whether an instruction of a verbal labeling strategy could enhance developmental coordination disorder (DCD) as well as developmental dyspraxia (DD) on the basis of relative changes in the Movement Assessment Battery for Children (MABC) Performance Test scores and the Kaufmann Hand Movement Test (KHMT) scores. The authors used a case formulation approach and taught 4 children with DCD during an 8-week intervention period. During the last half of the intervention, the authors additionally instructed the verbal labeling strategy for hand movements. Visual inspection of plotted time-series data from the MABC and the KHMT showed discordant trend lines in 3 children and concordant lines in 1 child. The results indicated that the verbal labeling strategy could be useful for temporary improvement of DD but not for DCD and that DCD and DD might not be directly related.
