Children with motor difficulties are a very varied group. In order to target interventions more effectively researchers have attempted to identify specific sub-groups; however, attempts to identify sub-groups and provide interventions accordingly have met with limited success. Currently interventions can be classified into two main types, namely, general abilities and normative functional approaches. The current study outlines the Manchester Motor Skills Programme (MMSP), which adopts a normative functional approach and has been developed jointly by educational psychologists (EPs), specialist teachers and schools. In order to evaluate the effectiveness of the MMSP a quasi-experimental repeated measures study was undertaken involving 24 children. The quasi-experimental study yielded a medium effect size, which is a promising result for a naturalistic intervention. Methodological limitations and areas of future research are considered and identified. (Contains 2 figures and 1 table.)
