Research paperThe efficacy of two activity-based interventions in adolescents with Developmental Coordination Disorder
Section snippets
What this paper adds
This study provides evidence of the efficacy of activity-based interventions in female adolescents with DCD.
Female adolescents with DCD respond positively to exercise interventions at the ICF levels of functioning.
Activity-based interventions administered once a week at moderate intensity may not be enough to improve aerobic endurance in this population.
Design
An assessor blinded, stratified, randomized trial was conducted between May and October 2016. Female adolescents identified as having DCD were assigned to receive either TFT or Wii training. Participants were stratified by grade, and randomly allocated to the two intervention groups through balloting by an independent person. Following balloting, the participants’ codes were concealed in opaque envelopes and distributed to them at their school. Participants who received even number codes were
Group differences at baseline
At baseline, the two groups were grade-matched and all were below the 16th percentile of the MABC-2. No differences were found with regards to age, body mass index (BMI) and the MABC-2 total score [Table 1]. 38 participants (TFT = 20, Wii = 18) were right-handed whereas 5 (TFT = 2, Wii = 3) were left-handed.
Changes in muscular strength, aerobic endurance, motor proficiency, functional performance, self-efficacy and participation

Discussion
The study investigated the efficacy of two activity-based motor interventions in female adolescents with DCD. The participants were randomly assigned to either Task-oriented Functional Training or Wii training and received 45-min of supervised training held once weekly for 14 weeks. We elected to implement a 14 week intervention (one session per week) at moderate intensity based on available resources (school schedule, personnel and logistics), data extracted from existing literature (Ashkenazi
Conclusion
In summary, we have demonstrated that activity-based interventions may yield positive benefits across the ICF levels of functioning in female adolescents with DCD. These two interventions seem to provide similar short-term benefits and can be implemented to enhance functional performance, participation and generalized self-efficacy. Further research is needed to evaluate the effectiveness of these interventions in clinical populations with DCD and the sustainability of improvements over time.
