Developmental Coordination Disorder (DCD)
Approximately 5 to 6% of primary school children have DCD. Children with DCD experience difficulty in acquiring and executing complex motor skills and this substantially interferes with their academic achievement or activities of daily living. The problems they experience may concern fine motor skills as well as gross motor skills. DCD is classified as an idiopathic condition and the diagnostic criteria rely on exclusion of neurological conditions that affect movement. Besides their problems with motor skills, children with DCD are less physically active and less physically fit than typically developing peers. Compared to typically developing peers children with DCD have lower anaerobic power and all five health-related physical fitness components are compromised: cardiorespiratory fitness, muscle strength, muscle endurance, flexibility and body composition. Moreover they are less physically active than typically developing peers and when they are active they tend to engage in less intense activities.

Achtergrond van het onderzoek
Background: Children with Developmental Coordination Disorder (DCD) are less physically active and less physically fit than typically developing peers. This leaves them at increased risk of developing (cardiovascular) diseases.
Objective: To examine the effects and feasibility of a treatment to improve the physical fitness and physical activity of 7 to 12 year old children with DCD.
Method: A convenience sample of at least 20 Dutch children with DCD from two schools for special education and two rehabilitation centers will be enrolled in this single arm trial. The intervention consists of a 2*60min/week group training for 10 weeks. In the course of the training parents will attend a parent meeting and receive an information package. The children and their families receive a Fitbit Zip to monitor their activity. By the end of the training the children and their parents set activity goals with a coach. During individual coaching sessions, the coach helps the participants to attain and evaluate their goals until 12 weeks after the last training session.
The effects of the intervention will be examined using the 20mSRT, JAMAR and Microfet hand held dynamometry, MPST and Actigraph accelerometry. Measurements will take place at baseline (T0, week 0), after the training (T1, week 11) and after the coaching (T2, week 23). During the training sessions heart rate will be monitored. The feasibility of the intervention will be examined by means of observations of the training sessions, a focus group with trainers, interviews with coaches and interviews with parents.
Doel van het onderzoek
Children with Developmental Coordination Disorder (DCD) are less physically active and less physically fit than typically developing peers. This leaves them at increased risk of developing (cardiovascular) diseases. The aim of the RenJeFit! (run to be fit) treatment is to increase or maintain the cardiorespiratory fitness, muscle strength, anaerobic power and physical activity. Besides that we aim to gain insight in the feasibility of the treatment.

Onderzoeksproduct en/of interventie
The treatment consists of two parts:
1. Training: 10 weeks, two times a week one hour of training at the rehabilitation centre or school for special education. The training consists of high intensity interval running, strengthening exercises and plyometric exercises
2. Lifestyle intervention: 12 weeks, consisting of: information package, parent meeting, coaching, provision of Fitbit Zip accelerometers

Belangrijkste voorwaarden om deel te mogen nemen (Inclusiecriteria)
- Officially diagnosed with DCD by a medical doctor according to DSM V criteria or DSM V criteria A, B and C are met and criterium D is checked in school record (pDCD)
- Age 7 to 12
- Needs related to enhancing physical fitness or (participation in) physical activity. This may manifest itself in: tiring quickly, being out of breath quickly, being unable to keep up with peers during physical activities, playing indoors a lot, playing a lot of passive games
- Motivation to participate in the treatment
- Parents/care takers are willing to invest their time and effort in the treatment: enabling the child’s participation in the training and active involvement in the lifestyle intervention
- It is expected that the child will benefit from the program (e.g. enhanced physical fitness or physical activity)
Belangrijkste redenen om niet deel te kunnen nemen (Exclusiecriteria)
- A medical status that contra-indicates exercise or maximal exercise testing
- Inability to function in a group (assessed by care provider, e.g.: the child is not able to participate in the PE class or sports activities, the child interferes other children in their activities)*
- Inability to follow instructions (assessed by care provider, e.g.: the child is easily distracted, the child often refuses to execute instructions, the child does not understand basic instructions) *
- Insufficient understanding of Dutch/English language that prevents the child to participate successfully in the program
* Comorbidities like ASD and ADHD are no reason for exclusion as long as the child is able to follow instructions, able to function in a group and if it is expected that the child benefits from the treatment.
