Functional kinematics of the wrist

Area of Science:

• Orthopedics
• Biomechanics
• Rehabilitation Science

Background:

• Carpal kinematics research has evolved over the last century.
• Understanding wrist functional kinematics is essential for diagnosing and treating injuries.
• Previous research has primarily focused on static measurements, with less emphasis on dynamic, coupled motions.

Purpose of the Study:

• To review historical and current concepts of healthy and injured wrist functional kinematics.
• To discuss the evolution of carpal kinematics measurement techniques and their impact on current understanding.
• To highlight the clinical relevance of recent findings, particularly the importance of coupled motion in radiocarpal injury rehabilitation.

Main Methods:

• Literature review of past and present concepts in wrist kinematics.
• Analysis of the progression of carpal kinematics measurement techniques.
• Synthesis of recent evidence on coupled motion in radiocarpal injury rehabilitation.

Main Results:

• The understanding of functional wrist kinematics has been significantly shaped by advancements in measurement techniques.
• Coupled motion is increasingly recognized as a critical factor in the early stages of radiocarpal injury recovery.
• Current clinical practices may not fully capture the dynamic, coupled movements essential for functional assessment.

Conclusions:

• Functional kinematics, especially coupled motion, is a clinically relevant outcome for wrist injuries.
• Clinicians need a framework for dynamically assessing coupled motion in the wrist.
• Individualized and tailored treatment approaches for carpal injuries can be enhanced by dynamic assessment of coupled motion.
