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

This proposal aims at investigating motor fatigability in upper limb strength during the performance of specific daily tasks in children with cerebral palsy (CP). Motor fatigability is defined as a reduction in the muscle force-generating capacity in the neuromuscular system that occurs during prolonged or ongoing activity. Based on our joint research (joint PhD Lieke Brauers, 2021) we know that motor fatigability is increased during grip strength testing in children with CP, and that this impacts the use of their arms and hands in daily activities. However, no research has been done on motor fatigability during prolonged (sub)maximal contractions while performing daily tasks, such as carrying or lifting a box, plate etc. (task-specific upper limb motor fatigability – TSUMF). Increased TSUMF might lead to unsuccessful performance of these daily tasks. The proposed research has three major aims. The first aim is to develop and validate new measurement methods and parameters for TSUMF and identify the impact of TSUMF on upper limb activities and participation in children with CP. The second aim is to identify the effects of existing upper limb interventions on TSUMF in children with CP . The third aim is the development of a specific training for TSUMF and to test its feasibility. These results will lead to the development of an optimal, effective and TSUMF targeted treatment approach.
