Introduction: Individuals with Autism Spectrum Disorder (ASD) and Intellectual Disability frequently exhibit motor difficulties that hinder their autonomy and limit participation in daily activities. Objective: This study aims to examine the potential of Dance Movement Therapy (DMT) to foster the development of basic motor skills in individuals with ASD, thereby contributing to their personal growth and functional independence. Methodology: A descriptive and interpretative case study employing a qualitative design was conducted with two participants diagnosed with ASD and intellectual disability. The qualitative data were analysed using Atlas.ti 9 software to identify variations in motor performance and bodily responses throughout the therapeutic process. Results: Regular engagement in DMT sessions facilitated both the acquisition and refinement of diverse motor skills—such as vertical jumping, longitudinal turning, and object manipulation and throwing—that had not been observed prior to the intervention. Discussion: When tailored to individual functional profiles, DMT promotes active participation, motor learning, and systematic monitoring of progress, underscoring its adaptability as a therapeutic approach. Conclusion: The findings suggest that DMT constitutes an effective therapeutic strategy for enhancing fundamental motor development and fostering autonomy and quality of life among individuals with ASD and intellectual disabilities.
