Abstract: Introduction - With an increase in awareness of children with developmental coordination disorder (DCD), the demand for physiotherapy has dramatically increased. While group motor training has been widely accepted and adopted in paediatric physiotherapy, empirical data comparing its effectiveness with the traditional individual treatment are rare. Objectives - The purpose of this study is to compare the effects of group versus individual motor training for children with developmental coordination disorder on motor proficiency, home exercise compliance and physical activity participation. Methodology - A single-blinded, randomized clinical trial was used. Twenty-three children (19 boys, 4 girls) aged 6 to 10, diagnosed with DCD and had not received any physiotherapy before were recruited in the study. All of them received an 8-week motor training at the Paediatric Outpatient Unit of the Physiotherapy Department of Kowloon Hospital from May to December 2007. After obtaining a written consent, children were randomly allocated to either group (n=12) or individual (n=11) motor training by drawing lots. Children were assessed with Movement Assessment Battery for Children (MABC) by independent assessors before and after an 8-week of motor training program. MABC was a widely used norm-referenced standardized measure used to measure the effectiveness of motor training. It measured 3 cluster areas - manual dexterity, ball skills, static and dynamic balance. Sum of these cluster scores yielded a Total Impairment Score (TIS). Home exercise compliance (HEx) and physical activity participation (PA) were also measured to determine if there was any correlation between motor competence and the level of activity participation. The 8-week motor training program, both on group and individual basis, addressed the same areas in postural control, agility, balance and coordination. At each session, children were given home exercises that reinforced the motor skills they learned and they were encouraged to participate in physical activities. Results - Twenty-three children (12 received group training and 11 received individual training) completed the 8-week motor training program. There was no defaulter. Both group and individual motor training demonstrated a significant improvement in TIS and MD (p<0.05, Wilcoxon Signed Ranks Test). There was no significant difference between groups in the improvement in MABC scores, HEx and PA (p>0.05, Mann-Whitney Test). A strong correlation was shown between HEx and PA (Spearman's correlation=0.460, p=0.027). Conclusion - The 8-week motor training program, either on group and individual basis, was equally effective in improving the motor proficiency of children with DCD. No statistical significant difference was detected in home exercise compliance and physical activity participation between group and individual motor training. The study supports group motor training as a means of improving motor proficiency other than individual motor training.
