Task-specific motor fatigability during daily activities of the upper limbs in children with Cerebral Palsy (Research)

This project explores upper-limb motor fatigability during daily activities in children with unilateral spastic cerebral palsy (USCP). Motor fatigability refers to a measurable decline in motor performance during sustained (static) or repetitive (dynamic) tasks. Previous research has shown that children with USCP experience greater static motor fatigability during grip and pinch tasks than typically developing (TD) peers. However, little is known about motor fatigability during prolonged maximal contractions in functional activities, such as carrying or lifting objects. To address this gap, this project focuses on task-specific upper-limb motor fatigability (TSUMF), defined as a decline in upper-limb motor performance during sustained functional tasks. The project comprises several objectives. First, the existing literature on motor fatigability in children with CP and TD peers will be systematically reviewed to establish the current state of knowledge and identify gaps in the field. Second, a new testing protocol for assessing TSUMF will be developed using the Activities of Daily Living–Test and Training Device (ADL-TTD). The psychometric properties of this protocol will subsequently be evaluated. Third, the protocol will be used to compare TSUMF between children with USCP and TD peers. Fourth, the project will investigate the effects of an existing upper-limb intervention on TSUMF in children with USCP. This research will contribute to a better understanding of how motor fatigability may affect functional upper-limb performance in children with USCP. By examining motor fatigability in tasks that more closely reflect everyday activities, the project may provide new insights into an aspect of upper-limb function that is not fully captured by other assessments. The findings may also help inform future research and the development of more targeted intervention strategies, with the broader aim of supporting children with USCP in performing everyday activities and improving their participation and quality of life.
