Assessment of the Spastic Upper Limb with Computational Motion Analysis

Area of Science:

• Biomechanics
• Clinical Assessment
• Rehabilitation Science

Background:

• Assessing upper extremity (UE) function is critical for diagnosing and treating various conditions.
• Current clinical methods may not fully capture the complex, coordinated movements of the UE.
• Integrating motion analysis and electromyography offers a more comprehensive approach to UE assessment.

Purpose of the Study:

• To present the current integration of 3D motion analysis and electromyography for clinical UE function assessment.
• To establish a normative database for specific UE tasks using this integrated approach.
• To analyze inter-joint correlations and understand movement coordination during UE tasks.

Main Methods:

• Utilized a combined system of 3D motion analysis and electromyography.
• Collected data during 5 specific Shriners Hospital Upper Extremity Evaluation tasks.
• Established a normative database including ranges of motion at task achievement and inter-joint correlations.

Main Results:

• A normative database for UE function was successfully established.
• Detailed ranges of motion and inter-joint coordination patterns were identified for each task.
• A strong relationship was observed between distal and proximal UE motion.

Conclusions:

• The integration of 3D motion analysis and electromyography provides a robust method for clinical UE assessment.
• Understanding inter-joint correlations is key to deciphering movement coordination.
• Treatment of proximal UE deficits may be more effective after addressing distal segment issues.
