All the tests were performed without shoes albeit with “Sensoria® Smart Socks”.➢ The dynamic test consists in transporting 1 object (e.g. puzzle piece, Lego®) from the therapist to the playing tablesituated 2 meters away and back again 15 times (see Figure 1).➢ The static test consists in playing while standing in front of a table for 3 minutes (see Figure 1).➢ Both assessments were repeated on three different days for each individual (9 assessments).➢ “Sensoria® Smart Socks” (SSS) are the validated WS3 used during the video-recorded tests. In this way, we were ableto collect data obtained from video-recording and WS approaches at the same time.➢ The result of the video-recording and WS approaches were analyzed.➢ In the WS approaches we used two different analysis, in the first analysis the signal of SSS was processed directly, inthe second analysis the signal was filtered and normalized before identifying the TTB steps.➢ The intraclass correlation coefficient - ICC (two-way mixed effects model, absolute agreement, single measurement)was calculated using SPSS ver. 23, to assess the reliability between the video-recording and SSS approaches inquantifying the mean percentage of toe steps and the mean percentage of the time spent in TTB.RESULTSQuantitative assessment of tip toe behavior in individuals with autism spectrum disorders using a structured methodology: comparison between video-recording and wearable sensor approaches.Valagussa Giulio1,2, Molteni Luca Emanuele1, Boccotti Martina1, Andreoni Giuseppe3,4, Grossi Enzo1BACKGROUND AND OBJECTIVESMATERIALS AND METHODS✓ Tip-toe behavior (TTB) is showed by about 20% of individuals with ASD and is poorly quantified with structured methods1.✓ In a previous study, we proposed a standardized method to quantify TTB during static and dynamic tasks using a video-recording approach in an ecological setting2. This testing approach isvery time-consuming and operator dependent requiring an operator to review the videos and computing the parameters.✓ To overcome these limitations, an instrumental approach using wearable sensors (WS) and an automated calculation system was developed and applied. Moreover, WS approach would alsopermit monitoring gait for a longer time during the day.✓ Objective: this study aims at implementing a WS-based protocol for the quantitative assessment of TTB and its validation by the comparison with the reference video-recording approach.➢ The “Sensoria® Smart Socks” used for the quantitative assessment of TTB in individuals with ASD showed good reliability compared to the reference video-recording approach duringstatic and dynamic tests. The results of this preliminary study support further research on a larger sample.(1) Villa Santa Maria Foundation – Autism Research Unit; (2) University of Milano-Bicocca – School of Medicine and Surgery; (3) Politecnico di Milano - Department of Design, Milano, Italy; (4) Scientific Institute IRCCS “E.Medea” - Bioengineering Laboratory, Bosisio Parini, Lecco, Italy.✓We assessed 3 individuals with ASD and TTB.✓The age was 10.9 yrs, 12.8 yrs and 13 yrs (3/3 males); their ADOS calibrated severity score was 9, 10 and 8, respectively.✓The normal distribution of data was confirmed (Shapiro-Wilk test p > 0.05).✓The ICC values of the mean percentage of the toe steps during the dynamic test and the mean percentage of the time spentin TTB during the static test were 0,862 (good) and 0,870 (good), respectively4.Corresponding author: giulio.valagussa@gmail.comReferences:1) Valagussa, G., Trentin, L., Signori, A., & Grossi, E.
