| Individualized balance therapy (with follow-up after and baseline follow-up) | Experimental | The therapy of the children will be given in intensive camps. A total of four camps are organized between April 2023 and August 2024. Each camp consists of six days of therapy, with a total therapy time of 40 hours. The central camp theme is "Circus", due to the attractiveness for children and the link with postural control. The intervention is functional, and divided in six activity categories: jumping, sitting balance, walking and running, circus, individual goals and group activities with focus on social interaction (Table 2). Each category should: 1. partially or fully cover the multisystemic framework of Horak, with the overall program covering the entire framework , 2. be fun and focusing on collaboration rather than competition. During three months prior to the intervention (camps), the children are followed up for six months and assessed at three time points. They will keep on following their usual physiotherapy sessions. |

| Changes in Balance Evaluation Systems Test (Kids-BESTest) scores | The Kids-BESTest is a standardized performance tool to assess postural control in children aged between 5 and 18 years old. The test has excellent reliability and consists of 36 items divided over 6 domains. Items are scored from 0 (worst performance) to 3 (normal performance) on 4-point Likert scale. Based on the summation of the task scores, the domain and total scores can be calculated and expressed as a percentage (minimum 0 - maximum 100). A higher score means a better balance performance. | 6 months pre-assessment, 3 months pre-assessment, pre-interventional assessment (up to two weeks before the start of the intervention), post-interventional assessment (up to two weeks after the end of the intervention), 3 months follow-up assessment |

| Change in scores on the Canadian Occupational Performance Measure (COPM) | The COPM is a client-centered outcome measure to determine and evaluate individual treatment goals. Measurement properties are satisfactory to excellent. In a semi-structured interview between therapist and child (over 8 years) or parents (under 8 years) balance-related problems in daily living are determined. After scoring for importance on a 10-point rating scale (minimum 1 - maximum 10), up to 3 self-selected treatment goals are identified. Each goal is self-rated based on the level of performance and satisfaction. In this study the Dutch version is used. Higher scores indicate more satisfaction and better performance. |

| Change in scores of the Test of Gross Motor Development, 3rd edition (TGMD-3) | The TGMD-3 is a functional process-oriented test to assess fundamental motor skills in children between 3 and 10 years old, with high test-retest reliability and validity. The test consists of 13 fundamental motor skills, subdivided across two subscales: locomotor and object control skills. Each skill is assessed with three to five performance criteria reflecting the developmental stage of the movement pattern. If a criterion is reached a score 1 is given, if not a score 0 is given. Each skill is assessed 2 times. All criterion scores of the two repetitions of each skill is summed up to obtain the domain scores. These raw domain scores are corrected for age and sex to a scaled score per domain (minimum 1 - maximum 20). Afterwards the scaled score for the total score (gross motor index) is calculated. The scaled scores are used for analyses. A higher score means a better motor performance. | 6 months pre-assessment, 3 months pre-assessment, pre-interventional assessment (up to two weeks before the start of the intervention), post-interventional assessment (up to two weeks after the end of the intervention), 3 months follow-up assessment |

| Changes in oxy-hemoglobin levels in different cortical brain regions during balance tasks (measured with functional Near-Infrared Spectroscopy) | To register cortical brain activity, fNIRS is applied simultaneously with preselected Kids-BESTest tasks. This optical neuro-imaging technique uses infrared light to monitor changes in the concentration (μmol/l) of oxygenated (HbO2) between the task and baseline condition. It is a reliable tool for within-subject measurements and can be reliably applied in children. Due to its portability, it can be used during postural control tasks and gait measurements. The NIRSport 2 (NIRx Medical Technologies, GE) with continuous wave (760nm; 850nm) imaging is used. The region of interests (ROI) targeted with fNIRS were determined based on evidence of brain areas responsible for adequate postural control tasks in healthy individuals and affected brain areas in children with DCD in a variety of tasks. The ROI include the inferior (IPL) and superior parietal lobe (SPL), premotor cortex (PMC) and the supplementary motor area (SMA). | 6 months pre-assessment, pre-interventional assessment (up to two weeks before the start of the intervention), post-interventional assessment (up to two weeks after the end of the intervention) |
