A Kinematic Analysis of Motor Planning and Movement Execution of Children With Autism Spectrum Condition

Study Overview
=================
Brief Summary
-----------------
Autism Spectrum Condition (ASC) is a behavioral syndrome characterized by a severe organizational disorder of thinking and major functions that regulate human adaptation. It is to be considered as a functional disorder, or of executive functions, whose dysfunction is expressed in the difficulty of making voluntary movements, sequentially coordinated with each other according to a purpose, and of initiating an action, planning and monitoring it by inhibiting inappropriate responses such as gesture perseveration. Literature studies suggest that, compared to children with typical development (TD) and regardless of cognitive status, children with ASC have pervasive motor dysfunction that results in universal difficulties in several aspects of motor function, including - (1) fine motricity, (2) some aspects of praxis while performing tasks based on imitation of sequences, (3) simultaneous coordination of both sides of the body during rhythmic tasks of the upper limbs, and́ (4) interpersonal coordination and synchrony. The hypothesis of the study is that by comparing these aspects in 2 groups of children with ASC and children with TD using A.I. systems, it will be possible to extract objective markers of motor deficits found in autism, facilitating the validation of measurements acquired with clinical scales. The objective of the study is to investigate the characteristics of manual motor planning and performance difficulties in children with ASC using kinematic measurements. 30 ASC children with medium-high functioning and 30 TD children, aged 7 to 13 years, IQ > 80, in the absence of motor deficits due to another clinical condition, will be recruited. The protocol will take place in a single session during which children will be video-recorded performing simple and complex rhythmic upper limb actions with a social partner. The presence of characteristic fine motor behaviors, practice errors, perseverations, movement variability, and interpersonal synchrony will be observed. The study will involve the use of 3 tasks contained in NEPSY-II: Finger tapping, Visual-motor precision, and Imitation of manual motor sequences. The videos will be recorded simultaneously and the different angles will allow hand kinematics to be extracted and analyzed with A.I. algorithms to measure displacement, velocity, acceleration, frequency and any other kinematic parameters highlighted. Thus, it is expected to identify objective markers of motor deficits found in children with ASC.

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Wechsler Abbreviated Scale of Intelligence - Second Edition (WASI-II) | The WASI-II is a general intelligence, or IQ test designed to assess specific and overall cognitive capabilities in clinical, educational, and research settings and is individually administered to children, adolescents and adults (ages 6-89). It is a battery of four subtests: Vocabulary (31-item), Block Design (13-item), Similarities (24-item) and Matrix Reasoning (30-item). In addition to assessing general, or Full Scale (range T Scores min 80 - max 320), intelligence, the WASI-II is also designed to provide estimates of Verbal (range T Scores min 40 - max 160) and Performance (range T Scores min 40 - max 160) intelligence consistent with other Wechsler tests. For each scale higher score corresponds to better performance. | The evaluation session will be scheduled before of kinematics measurements. The test needs approximately 25-40 minutes to complete. | 
| Movement Assessment Battery for Children - Second Edition (MABC-2) | The MABC-2 identifies and describes impairments in motor performance of children and adolescents 3 through 16 years of age. The MABC-2 consists of 2 components: 24 tests divided into 8 tasks for 3 age groups (3-6; 7-10; 11-16), for 3 areas (Manual dexterity, Aiming and grasping, Balance). There is a total score (TS) and separate scores for the 3 areas. Age-and percentile-adjusted standardized scores are provided for each section of the test and for the TS: TS>67 or a percentile >15th indicates performance in the normal range; 57 <TS> 67 or 6th <percentile >15th defines an at risk category with the need for close monitoring; TS ≤56 or percentile ≤5th indicates the presence of a significant motor problem. The test allows to draw a qualitative description of the ways in which the child performs each task; An observation checklist consisting of 43 items divided into 3 sections to be completed by an adult who has the opportunity to observe the child in his daily motor activities. | The evaluation session will be scheduled before of kinematics measurements. The test needs approximately 20-40 minutes. The checklist needs approximately 10 minutes. | 
| Behavioral Rating Inventory of Executive Function (BRIEF) | The BRIEF-2 is a set of questionnaires for parents and teachers designed to evaluate executive function. The BRIEF-2 now uses 10 clinical scales: Inhibit; Self-Monitor; Shift; Emotional Control; Initiate; Task Completion; Working Memory; Plan/Organize; Task-Monitor; Organization of Materials. T scores (min 31 - max >99) and percentile score (min 3 - max >99) are provided for three broad indexes (Behavior Regulation, Emotion Regulation, and Cognitive Regulation) and for the Total Score. Higher score corresponds to better performance. | The evaluation session will be scheduled before of kinematics measurements. Questionnaires take 10 minutes to administer. |
