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.

The Kaligo + Score will be taken twice a week during baseline and intervention and once a week during follow-up.
Fondation ILDYS
Brest, France
RECRUITINGComposite score brings together a set of parameters defining writing efficiency (static, kinematic and pressure) : Kaligo +
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).
Time frame: 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
Assessing the ecological impact and its generalisation
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).
Time frame: 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.

Handwriting Proficiency Screening Questionnaire for Children (HPSQ-C). 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).
Time frame: 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
Assessing the ecological impact and its generalisation
Concise Assessment Scale for Children's Handwriting (BHK). In the BHK \[Brave Handwriting Kindergarten\], the child is asked to copy a text for 5 minutes. Blind double scoring is used (the scorer does not know when the child has copied the text). A degradation score is calculated: the higher the score, the more "degraded" the quality of the child's handwriting. The standardized score is taken into account for inclusion (to situate the child's performance in relation to his class), while the raw score is taken into account over the course of the intervention (allowing comparison of the subject with himself). Psychometric qualities are documented in the test manual.
Time frame: 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.
Assessing the ecological impact and its generalisation
NEPSY-II is the only single measure that allows clinicians to create tailored assessments across six domains, specific to a child's situation SUBTESTS - ORIENTATION SUBTEST - VISUO-MOTOR PRECISION SUBTEST - INHIBITION SUBTEST - FACE RECOGNITION
Time frame: 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.
Assessing the ecological impact and its generalisation
Purdue Pegboard Test (PPT). Test of manual dexterity and bimanual coordination. The child must place rods in holes on a board as quickly as possible, using the dominant hand, the non-dominant hand, then both hands simultaneously. In a final condition ("assembly"), the child must place a rod in one of the holes, then a washer, a tube and another washer, using both hands alternately. Raw scores (number of correctly placed and assembled pieces) are taken into account.
Time frame: 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.
Assessing the ecological impact and its generalisation
Written Language Analytical Battery (BALE). In the BALE \[Batterie Analytique du Langage Ecrit, Analytic test of the written language\], the child is asked to write (under dictation) simple, complex and frequent irregular words from the French language, and to read regular and frequent irregular words. For the purposes of this study, only raw scores will be taken into account, in order to compare the subject with himself.
Time frame: 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.
- Evaluate the maintenance of performance over time after the end of the intervention
Evolution of the Kaligo + score. Kaligo + Score: This composite score brings together a set of parameters defining writing efficiency (static, kinematic and pressure).
Time frame: This assessment will be carried out at the end of the intervention and every week for a month.
Assessing the specific nature of 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
Time frame: 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
