Brief summary
Writing is a fundamental skill, crucial to a child's success at school and the development of independence. Around 30% of children present difficulties in learning to write, and for some of them (10%), these difficulties persist for a long time. Adapted learning can improve their handwriting. Initial studies into the use of new technologies (tablets, virtual reality headsets) have shown that they can help children learn to write. Attractive to children, these interfaces make it possible to apply new paradigms (e.g. enrichment of feedback \[sonification\], variation of writing media) that have proved effective, mainly with children with 'typical' development. The Kaligo+ solution is based on the latest scientific advances to offer an innovative approach to learning to write, particularly for children with significant difficulties in this area. This study proposes to test the benefits of the Kaligo+ solution on 15 children with writing difficulties. The main objective of this pilot study is to demonstrate improved writing performance following use of the Kaligo+ solution in children aged 6 to 11 with writing difficulties, using a Single Case Experimental Design (SCED) methodology.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Composite score brings together a set of parameters defining writing efficiency (static, kinematic and pressure) : Kaligo + | This assessment will be carried out twice a week up to 19 weeks during the baseline and intervention and once a week up to 1 month after the interventiona | Static parameters: density, height, width and length Kinematic parameters: Time (in air and on paper), speed, number of speed inversion, median frequency of the speed, jerk and acceleration. Pressure: Median, 60th percentile, median frequency of the pressure change. The score is normalized between 0 (worst) and 1 (best). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Assessing the ecological impact and its generalisation | This assessment will be conducted during the first week of the baseline, in the 10th week of the intervention, and once more one month after the intervention. | Movement Assessment Battery for Children \| Second Edition (M-ABC-II). Questionnaire to assess motor skills in everyday situations, comprising 3 parts: part A movement in a static and/or predictable environment, part B movement in a dynamic and/or non-static environment, part C non-motor factors that can affect movement. A raw score is obtained for each of these parts, as well as a total motricity score (A + B). |
| - Evaluate the maintenance of performance over time after the end of the intervention | This assessment will be carried out at the end of the intervention and every week for a month. | Evolution of the Kaligo + score. Kaligo + Score: This composite score brings together a set of parameters defining writing efficiency (static, kinematic and pressure). |
| Assessing the specific nature of the intervention | This assessment will be conducted during the first week of the baseline, in the 10th week of the intervention, and once more one month after the intervention | Evolution of performance on an untrained task. It will be demonstrated by the absence of as great an improvement in the control variable (face recognition task) compared with the improvement recorded in the primary endpoint |
| Assessing satisfaction with the intervention for the child and his or her family | during the last visit, 1 month after intervention | The CSQ 8 is a short customer satisfaction questionnaire. The CSQ8 is the benchmark questionnaire for assessing satisfaction among parents, children and teenagers. |
| Assessing the acceptability and usability of the solution for families and professionals | during the last visit, 1 month after intervention | Mobile Application Rating Scale (MARS). This validated questionnaire makes it possible to assess the quality of mobile healthcare applications in a way that is transparent for healthcare professionals and patients alike. |
