Task-specific Maximal Strength and Motor Fatigability During Daily Activities of the Arms and Hands in Typically Developing Children

March 17, 2026 updated by: Katrijn Klingels, Hasselt University
The aim of this study is to measure task-specific maximal strength and motor fatigability during functional daily activities involving the upper limbs in typically developing children. The focus is on determining the test-retest reliability of these measurements. In addition, the results are compared with existing data from children with cerebral palsy (CP). Through this comparison, we aim to gain insight into the motor limitations experienced by children with CP when performing everyday tasks.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Motor fatigability during functional upper limb lifting tasks
Time Frame: Two assessments separated by 20 minutes to assess test-retest reliability
Motor fatigability during lifting tasks will be quantified using the Static Fatigue Index (SFI, %) derived from the force-time curve recorded with the Activities of Daily Living - Test and Training Device (ADL-TTD). Higher SFI values indicate higher motor fatigability.
Two assessments separated by 20 minutes to assess test-retest reliability

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Maximal strength during functional upper limb lifting tasks
Time Frame: Two assessments separated by 20 minutes to assess test-retest reliability
Maximal strength will be measured as peak force in Newtons (N) during lifting tasks using the Activities of Daily Living - Test and Training Device (ADL-TTD).
Two assessments separated by 20 minutes to assess test-retest reliability
Object orientation during functional upper limb lifting tasks
Time Frame: Two assessments separated by 20 minutes to assess test-retest reliability
Object orientation will be quantified in degrees (°) using an inertial measurement unit (IMU) integrated into the ADL-TTD during lifting tasks.
Two assessments separated by 20 minutes to assess test-retest reliability
