Area of Science:

Biomechanics
Human Movement Analysis
Medical Engineering

Background:

Understanding human movement kinematics is vital for both fundamental research and practical medical applications.
Kinematic data informs the assessment of limb function, diagnosis of joint diseases, and development of prosthetic devices.

Purpose of the Study:

To categorize and explain the primary approaches to human movement kinematic analysis.
To review current measurement techniques and their respective strengths and weaknesses.

Main Methods:

Describing gross limb segment movement using Eulerian angles for joint rotation.
Analyzing joint articulating surface motion with the screw displacement axis concept.
Discussing measurement techniques: electrical linkage, stereometric/roentgenographic, and accelerometric methods.

Main Results:

Two main kinematic analysis categories: gross joint rotation and detailed articulating surface motion.
Identification of Eulerian angles for joint motion and screw displacement axis for surface analysis.
Classification of measurement techniques with their operational principles and data characteristics.

Conclusions:

Kinematic analysis provides essential insights into human biomechanics for clinical and research purposes.
Diverse measurement techniques exist, each with specific advantages and limitations for capturing movement data.
Further application examples of upper and lower extremity movement analysis will be presented.
