About

Autism Spectrum Disorder (ASD) affects social communication and motor coordination, with less synchrony with others and atypical gait patterns. Relationship with the adult or speed modify gait parameters in children diagnosed with ASD between 4 and 6 years old. Methodology: a cross-sectional observational design was carried out. The aim of this study was to analyze gait pattern variations in children with ASD in different speed conditions and modifying the social environment.

Full description

Study Design:

This is a quasi-experimental, cross-sectional study designed to assess the influence of rhythm and interpersonal relationships on gait parameters in children diagnosed with Autism Spectrum Disorder (ASD). The study involved 30 children, aged 4 to 6, diagnosed with ASD (level I or II), who demonstrated independent walking ability without assistive devices. The children were recruited from Fundación AMÁS, an early intervention center.

Intervention:

The study aimed to analyze the gait of children under three different speed conditions-normal (120 beats per minute), slow (100 beats per minute), and fast (140 beats per minute)-while walking alongside either a familiar adult or a stranger. The intervention involved the following steps:

Preparation: Each child was informed about the walking activity and the adult who would accompany them. They were instructed to walk alongside the adult for a distance of 10 meters.

Walking Conditions:

Walking with a Familiar Adult: Children walked alongside an adult they knew, maintaining the specified rhythm.

Walking with a Stranger: Children walked alongside an unfamiliar adult at the same designated rhythm.

Speed Variation: The rhythm was controlled using a metronome, which only the accompanying adult could hear. The adult was instructed to adjust their walking pace according to the specified rhythm while guiding the child.

Recording and Analysis: The walking sessions were recorded using a camera positioned at a lateral view, ensuring consistent height and distance. The central 2 meters of the 10-meter path were analyzed using Kinovea© software to assess gait parameters.

Outcome Measures:

The study sought to evaluate several dependent variables, including:

Stride Length: The distance covered with each step. Step Time: The duration of each step. Cadence: The number of steps taken per minute. Velocity: The speed of walking measured in meters per second. Joint Amplitudes: The angles at which the hip, knee, and ankle joints moved during each phase of the gait cycle.

Study Population:

The study included children with ASD who attended regular therapy sessions at Fundación AMÁS. Inclusion criteria required children to be between 4 and 6 years old, with a clinical diagnosis of ASD (level I or II), and the ability to walk independently. Exclusion criteria included any associated syndromes or recent lower-limb interventions.

Walking Intervention with Varying Speeds and Social Interaction in Children with Autism Spectrum Dis

Experimental group

Description:

This arm of the study focuses on a single group of participants consisting of 30 children aged 4 to 6 years diagnosed with ASD. The objective is to evaluate how varying walking speeds and social interactions influence gait parameters. Participants will engage in a structured walking intervention under three conditions: normal speed (120 bpm), slow speed (100 bpm), and fast speed (140 bpm). Each child will walk with two different types of adult companions: a familiar adult (e.g., caregiver) and an unfamiliar adult. This design allows for a comprehensive assessment of gait characteristics in response to different social contexts and pacing. Each child will complete a 10-meter walking task, with gait parameters such as stride length, step time, cadence, velocity, and joint amplitudes being recorded using video analysis software (Kinovea©).The results will contribute to understanding how children with ASD adapt their locomotion to social cues and varying speeds
