Assessment of presentation patterns, clinical severity, and sensorial mechanism of tip-toe behavior in severe ASD subjects with intellectual disability: A cohort observational study / Giulio VALAGUSSA in Autism Research, 10-9 (September 2017)

The first study included 69 consecutive ASD subjects (57 males, mean age = 14 years—3.7 SD) under observation at our institute. A therapist assessed the presence of TTB during standing, walking, and running through direct observation and an interview with the subjects main caregiver. The prevalence of TTB was 32%. We found three clinical presentation patterns of TTB: (1) present when standing, walking and running (45.5%), (2) present when walking and running (18.4%), or (3) present only when running (36.4%). TTB subjects were more frequently nonverbal than those without TTB (72.7% vs. 44.6%-P = 0.03). On the other hand, no significant difference in ASD severity according to the ADOS scale was found between TTB and non-TTB subjects. In the second study, carried out in a subgroup of 14 ASD subjects (7 TTB and 7 non-TTB), we evidenced that a soft floor surface (foam mats) made a substantial difference in reducing the TTB phenomenon. TTB is frequently present in ASD individuals and may occur in three mutually exclusive modalities, which ultimately defines what is commonly known as toe walking. The presence of TTB seems correlated to the severity of language delay. Foot contact on soft surfaces reduces TTB both during static and/or dynamic tasks. Further evaluation is needed to clarify the potential pathophysiological implications of this phenomenon.

Quantitative assessment of tip-toe behavior in individuals with autism spectrum disorder and intellectual disability: A cross-sectional study / Giulio VALAGUSSA in Autism Research, 17-2 (February 2024)  

Public ISBD [article]  inAutism Research > 17-2 (February 2024) . - p.311-323 Titre : Quantitative assessment of tip-toe behavior in individuals with autism spectrum disorder and intellectual disability: A cross-sectional study Type de document : texte imprimé Auteurs : Giulio VALAGUSSA, Auteur ; Giulia PURPURA, Auteur ; Valeria BALATTI, Auteur ; Luca TRENTIN, Auteur ; Alessio SIGNORI, Auteur ; Enzo GROSSI, Auteur Article en page(s) : p.311-323 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract The term "toe walking" describes walking on the toes with a lack of heel strike upon initiation of the stance phase of gait. In individuals with autism spectrum disorder (ASD), this phenomenon, or "tip-toe behavior" (TTB), can be present in a substantial proportion of subjects even during standing. In this study, we investigated TTB in 50 persons with ASD (age range 4-26 years). We evaluated TTB through an observational/report-based assessment protocol. Subsequently, we employed a new structured video-based coding protocol based on standardized video recordings, focusing on static and dynamic conditions. Finally, the findings of the two protocols were compared. Twenty-four subjects with TTB were identified and classified according to three functional groups: TTB1, present only during running (6 subjects); TTB2, present during walking and running (11 subjects); and TTB3, present during standing, walking, and running (7 subjects). Moreover, we found that TTB3 subjects exhibited a significantly higher quantity of TTB compared with subjects in the TTB1 and TTB2 groups during both standing and walking tests. Additionally, a high quantity of TTB in the static test was found to be related to a high quantity of TTB in the dynamic test. Variables such as age, autism severity, intellectual disability, and gender were not significantly associated with the mean percent of TTB both in static and dynamic tests in multivariate analysis. This structured video-based coding approach appears feasible and useful for assessing TTB in individuals with ASD and it has the potential to provide insights into TTB trajectories and aid in designing possible interventions.

Toe Walking Assessment in Autism Spectrum Disorder Subjects: A Systematic Review / Giulio VALAGUSSA in Autism Research, 11-10 (October 2018)  

Public ISBD [article]  inAutism Research > 11-10 (October 2018) . - p.1404-1415 Titre : Toe Walking Assessment in Autism Spectrum Disorder Subjects: A Systematic Review Type de document : texte imprimé Auteurs : Giulio VALAGUSSA, Auteur ; Luca TRENTIN, Auteur ; Alessio SIGNORI, Auteur ; Enzo GROSSI, Auteur Article en page(s) : p.1404-1415 Langues : Anglais (eng) Mots-clés : assessment  autism spectrum disorder  systematic review  toe walking  treatment Index. décimale : PER Périodiques Résumé : There is increasing evidence that autism spectrum disorder (ASD) subjects have also motor impairments. Toe walking (TW) is a phenomenon that can be found in ASD subjects during gait, even if this condition was found not to be necessarily related only to walking, since these children often also stand and run on their tiptoes. Since persistent TW in ASD subjects may contribute to secondary shortening of the Achilles's tendon, it becomes important to have an assessment tool and/or outcome measure for both the clinical and rehabilitative settings. The aim of this systematic review is to critically evaluate and describe the methods employed to assess toe walking in ASD subjects. The systematic review protocol was previously registered on PROSPERO. We conducted an extensive literature search in PubMed, CINAHL, PsycINFO, The Cochrane Library, and Scopus databases. There were no restrictions on the types of study design eligible for inclusion. Ten studies were included in the systematic review. Risk of bias of the included studies was conducted using the following instruments depending on the study types: STROBE Statement, Cochrane risk of bias tool, and CARE checklist. Almost all the included studies (8/10) proposed a tip-toe behavior (TTB) assessment only during walking. Nine out of ten of the included studies assessed TTB using a qualitative methodology. The results evidenced the heterogeneity of qualitative methods and a lack of a structured quantitative test to assess toe walking in ASD subjects. Autism Res 2018, 11: 1404-1415.
