Clinical Trial Summary

Objectives: To compare the effectiveness of Tai Chi-muscle power training (TC-MPT), Tai Chi (TC) alone, muscle power training (MPT) alone, and usual care (as a control) for improving the limits of stability (LOS) of balance control in children with developmental coordination disorder (DCD) and to explore the relationship among LOS, falls, and functional performance in this population. Design: A randomized controlled trial. Sample: 156 children with DCD. Interventions: TC-MPT, TC alone, MPT alone, or usual care for 12 weeks. Major outcomes: Outcomes will be evaluated at baseline, post-intervention, and a 3-month follow-up. An LOS test will give a dynamic LOS score, an isokinetic test will quantify leg muscle force production speed, Movement Assessment Battery for Children-2 will be used to assess functional motor performance, and fall history will be obtained via interviews. Anticipated results and significance: The TC-MPT group is predicted to display the best LOS balance performance, which is associated with reduced fall incidents and improved functional performance. This novel training regime could be readily adopted into school or clinical settings to improve physical well-being in children with DCD, an outcome with positive socioeconomic implications.


Description:

Children with developmental coordination disorder (DCD), who comprise about 6% of the primary school population, display marked movement and balance difficulties. Reduced limits of stability (LOS), the maximum spatial area in which a standing person can lean, in these children is a major concern because it predisposes them to falls and affects their motor development. The investigator's recent studies demonstrate the underlying causes of impaired LOS in children with DCD to include suboptimal volitional control of the center of gravity (COG) and reduced leg muscle force production speed. Tai chi (TC) is a particularly suitable exercise for improving COG control, yet the speed of movement is too slow to improve muscle power. Hence, muscle power training (MPT), which can hasten leg muscle force production, in conjunction with TC (TC-MPT) may be an ideal therapy for improving LOS, preventing falls, and improving functional performance in children with DCD. In the proposed study, the investigators will pioneer the treatment of both COG control and leg muscular deficit in children with DCD by incorporating MPT into TC. It is hypothesized that the LOS of balance control in these children can best be improved by treating both their COG control and muscular deficits. This hypothesis is supported by the prediction that TC-MPT is superior to either TC or MPT alone in improving LOS balance performance. Furthermore, improved LOS is associated with fewer fall incidents and better functional performance in children with DCD. Objectives: To compare the effectiveness of TC-MPT, TC alone, MPT alone, and usual care (as a control) for improving the LOS of balance control in children with DCD and to explore the relationship among LOS, falls, and functional performance in this population. Design: A randomized controlled trial. Sample: 156 children with DCD. Interventions: TC-MPT, TC alone, MPT alone, or usual care for 12 weeks. Major outcomes: Outcomes will be evaluated at baseline, post-intervention, and a 3-month follow-up. An LOS test will give a dynamic LOS score, an isokinetic test will quantify leg muscle force production speed, Movement Assessment Battery for Children-2 will be used to assess functional motor performance, and fall history will be obtained via interviews. Anticipated results and significance: The TC-MPT group is predicted to display the best LOS balance performance, which is associated with reduced fall incidents and improved functional performance. This novel training regime could be readily adopted into school or clinical settings to improve physical well-being in children with DCD, an outcome with positive socioeconomic implications.

Intervention

Behavioral:
TC-MPT
Participants will receive two levels of training within each 90-minute session over a 12-week period: (1) TC training and (2) MPT. The TC training protocol consists of five basic TC movements. After receiving TC training, the participants in this group will take a 5-minute break and then receive MPT. During MPT, the participants will contract their major postural muscles bilaterally as fast as possible against a resistance equivalent to 70% of one repetition maximum.
TC
Children in the TC group will skip the MPT session and practice TC movements repeatedly for 90 minutes. The exercise progression pattern in the TC-alone group will be the same as that in the TC-MPT group.
MPT
Those children in the MPT group will perform strengthening exercises repeatedly for 90 minutes, with a short 5-minute break between the three sets of exercises if necessary. The exercise progression pattern in the MPT-alone group will be the same as that in the TC-MPT group.

Outcome

Type Measure Description Time frame Safety issue
Primary Change of limits of stability Computerized dynamic posturography - A dynamic limits of stability score (%), from 0-100%. A higher score represents a greater limits of stability (better). 0, 3, 6 months
Primary Change of center of gravity control Computerized dynamic posturography - time to complete the DLOS test (sec) 0, 3, 6 months
Secondary Change of functional motor performance (raw data) Movement Assessment Battery for Children-2 total test score 0, 3, 6 months
Secondary Change of functional motor performance (compared to norm) Movement Assessment Battery for Children-2 total percentile rank (from 0-100 percentile). A higher percentile represents better functional motor performance. 0, 3, 6 months
Secondary Change of leg muscle force production speed Isokinetic/ hand-held dynamometry: time taken to reach peak torque of the knee flexor and extensor muscles 0, 3, 6 months
Secondary Change of leg muscle strength Isokinetic/ hand-held dynamometry: peak torque of the knee flexor and extensor muscles 0, 3, 6 months
Secondary Change of fall history Self-reported and parent-reported falls 0, 3, 6 months
