Area of Science:

• Rehabilitation Science
• Biomedical Engineering
• Clinical Biomechanics

Background:

• The International Classification of Functioning, Disability and Health (ICF) model provides a framework for understanding disability.
• The relationship between body structure/function (spasticity, kinematics) and activity (e.g., reaching, lifting) in children with cerebral palsy (CP) is not fully understood.
• The Wolf Motor Function Test (WMFT) is a key tool for assessing activity limitations.

Purpose of the Study:

• To investigate the directional relationships between body structure/function variables and activity domain variables measured by the WMFT in children with CP.
• To determine how spasticity and movement kinematics relate to functional abilities.

Main Methods:

• Nineteen children with CP participated.
• Spasticity was measured using the Tardieu scale.
• Movement kinematics during reaching were captured using an 8-infrared motion capture system (VICON).
• Functional abilities were assessed using the Wolf Motor Function Test (WMFT).
• Correlational analyses were performed.

Main Results:

• A fair to strong correlation was found between kinematic data (body structure/function) and WMFT variables (activity).
• Eleven out of 18 kinematic variables showed significant relationships with WMFT outcomes.
• No significant correlation was observed between Tardieu spasticity scores and kinematic data or WMFT variables.

Conclusions:

• Movement kinematics are closely associated with functional abilities (WMFT) in children with CP.
• Tardieu spasticity measures did not correlate with kinematic data or WMFT outcomes.
• Kinematic analysis provides valuable insights for CP assessment and intervention, suggesting spasticity alone may not fully capture functional limitations.
