Task performance in grip control differs in autistic adults, indicating persistent motor dysfunction linked to age and traits.

This study aims to examine grip control in middle-aged and older autistic adults and its relation to demographic factors and autistic traits.
Participants included 52 autistic and 56 non-autistic adults aged 30-73 years.
Visually guided precision grip tasks assessed grip control features: temporal, spatial, and dynamic.
Two testing conditions: varying motor output demands (target force test) and visual feedback (visual gain test).
Autistic adults showed prolonged grip duration and delayed reaction times during precision grip tasks.
Grip force variability increased for autistic adults across both conditions, especially in older subgroups.
Temporal grip variability was significantly associated with age and repetitive behaviors.

Wang et al. (2025) studied this question.
