Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Hypothesis: The TKD group participants will have improved skeletal development and motor proficiency outcomes after adapted TKD training compared with the controls.
Design and subjects: In this prospective, randomised, single-blinded controlled trial, approximately 104 children with DCD (6-9 years old) will be randomly assigned to either the adapted TKD group (n\~52) or the control group (n\~52).
Interventions: Subjects in the intervention group will receive adapted TKD training for 3 months (one supervised session/week plus daily home training, 1 hour per session), while subjects in the control group will receive no TKD training during the study period.
Study instruments and outcomes: Primary outcome measures: delay in skeletal development and motor proficiency will be measured by an ultrasonic bone age system and the Movement Assessment Battery for Children, respectively. Secondary outcome measures: eye-hand coordination and standing balance will be measured by a computerised finger pointing test and the Sensory Organisation Test, respectively (pre-, post- and follow-up measurements).
Data analysis: Data will be analysed via repeated-measure analysis of (co)variance followed by post-hoc tests, if appropriate (alpha = 0.05).

Expected results: Based on the results of our pilot study, the investigators expect that the subjects in the adapted TKD group will have improved skeletal development and motor proficiency outcomes after TKD training compared with the controls.

Adapted Taekwondo training
An adapted TKD training regime which was developed by our research team \[16\] will be used in this study. This training programme is designed to train balance control, eye-hand coordination and facilitate skeletal development for children with DCD. The high-impact striking techniques (e.g., punching and blocking) incorporated in the programme may stimulate bone growth \[15\]. Subjects who are assigned to the TKD training group will attend a weekly 1-h session of TKD training that will be held at the University of Hong Kong for 12 weeks. All TKD training sessions will be conducted by a qualified World Taekwondo Federation black belt coach.

Control
Subjects who are assigned to the DCD-control group will receive no TKD training during the study period. Instead, they will participate in jogging exercise daily (one hour per day) for 12 weeks. Participants will be encouraged to jog to school or other places every day, as appropriate. Pedometers will be used to monitor their exercise level and enhance habitual physical activity. The pedometer count (steps per day) will be documented in a log book by the parents. Signed log books will be returned to our research personnel after the intervention period. In addition, children with DCD in this group will receive an adapted TKD training menu and 12 training/demonstration sessions immediately after the follow-up testing is completed.
