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

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.

Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age between 7 and 18 years
  • Sufficient understanding of the Dutch language to comprehend and perform the test procedures (also applicable to the parents/legal guardians)

Exclusion criteria

  • Upper limb movement problems within the past 6 months
  • Trauma to the upper limb within the past 6 months

Treatment and study plan

Primary outcomes

  1. 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.

Secondary outcomes

  1. 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).

  2. 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.
