Summary
Individuals with chronic stroke exhibit altered scapular kinematics in both arms, affecting arm movement. However, these kinematic changes do not correlate with paretic arm function in daily activities.
Area of Science:
- Neuroscience
- Biomechanics
- Rehabilitation Science
Background:
- Stroke survivors often experience impaired arm function due to altered scapular motion.
- Understanding these kinematic changes is crucial for improving daily activities.
Purpose of the Study:
- To evaluate scapular kinematics in individuals with chronic stroke.
- To assess the correlation between altered scapular motion and paretic arm function.
Main Methods:
- Compared scapular kinematics during arm elevation/lowering and hair combing in 17 chronic stroke survivors and 17 controls.
- Assessed paretic arm function using the Motor Activity Log (MAL-30).
Main Results:
- Stroke survivors showed increased scapular internal rotation and anterior tilt in both arms compared to controls.
- These kinematic alterations were observed during various arm movements and the hair combing task.
- No significant correlation was found between scapular kinematics and MAL-30 scores.
Conclusions:
- Chronic stroke leads to bilateral scapular kinematic alterations.
- These observed kinematic changes are not associated with the functional use of the paretic arm.
