An interventional study of Rhythmical auditory stimulation gait training and muscle power training (RAS-MPT) and Rhythmical auditory stimulation gait training (RAS) in Developmental Coordination Disorder, sponsored by The University of Hong Kong. Status unknown at 1 site in Hong Kong. Open to participants aged 6 Years to 9 Years. Per ClinicalTrials.gov, last updated 2019-02-12.
Sponsored by The University of Hong Kong · Not applicable, Interventional, and Treatment
Objectives: To compare the effectiveness of RAS-MPT, RAS alone, MPT alone, and usual care (as a control) for improving the overall gait performance of and reducing falls in children with developmental coordination disorder (DCD) and to explore the relationship between gait performance and falls in this population.
Design: A randomized controlled trial. Sample: 76 children with DCD. Interventions: RAS-MPT, RAS alone, MPT alone, or usual care (12 weeks). Major outcomes: Outcomes will be evaluated at baseline, post-intervention, and a 6-month follow-up. Comprehensive gait analysis will produce spatiotemporal gait parameters (e.g., velocity and stride length), kinematic gait parameters (e.g., knee joint motions), and leg muscle EMG outcomes; an isokinetic test will quantify leg muscle strength and force production time; and fall histories will be obtained via interviews. Anticipated results and significance: The RAS-MPT group is predicted to display the best gait performance, which is associated with reduced fall incidents. This novel training regime can be readily adopted in school, clinical, or home settings to improve locomotor ability in children with DCD, an outcome with positive socioeconomic implications.

Exclusion Criteria:
Rhythmical auditory stimulation gait training and muscle power training group
Behavioral: Rhythmical auditory stimulation gait training and muscle power training (RAS-MPT)
Rhythmical auditory stimulation gait training group
Behavioral: Rhythmical auditory stimulation gait training (RAS)
Muscle power training group
Behavioral: Muscle power training (MPT)
Usual care group
Other: Controls
The RAS-MPT group will attend a 60-minute training session once a week and home exercises (twice/week) for 12 weeks. Participants will receive two levels of training within each 60-minute session: (1) RAS-treadmill training and (2) MPT.
The RAS group will attend a 60-minute training session once a week and home exercises (twice/week) for 12 weeks. Participants will receive RAS-treadmill training repeatedly within each 60-minute session.
The MPT group will attend a 60-minute training session once a week and home exercises (twice/week) for 12 weeks. Participants will receive muscle power training repeatedly within each 60-minute session.
Participants in the control group will receive no intervention during the study period, but continue with their normal daily activities and usual medical care. They will receive the same training as the RAS-MPT group after the study.
