Highlights
- •Individuals with chronic stroke present bilateral scapular kinematics alterations.
- •Chronic stroke favors increased scapular internal rotation and anterior tilt.
- •Scapular kinematics are not correlated with the use of the paretic arm.
Abstract
Background
Stroke can lead to altered scapular motion that may limit the ability to perform activities
of daily living. The aims were to evaluate scapular kinematics of individuals with
chronic stroke and the correlation with paretic arm function.
Methods
Scapular kinematics was assessed in thirty-four individuals (Chronic stroke = 17; controls = 17) during arm elevation and lowering in scapular and self-selected planes, and during
hair combing. The use of the paretic arm to perform activities of daily living was
assessed by the Motor Activity Log (MAL-30). Scapular kinematics was compared among
paretic and non-paretic arms, and controls. Correlation between scapular kinematics
and MAL-30 was also verified.
Findings
Paretic and non-paretic arms showed increased scapular internal rotation (p < 0.05) during arm lowering in the scapular plane, and during arm elevation and lowering
in the self-selected plane compared to controls. Increased internal rotation (p < 0.05) was also found in the paretic arm during hair combing compared to controls.
Increased scapular anterior tilt (p < 0.05) was observed in the paretic arm during arm elevation while performing the activity
of hair combing and during arm elevation and lowering in the scapular and self-selected
planes compared to controls. The non-paretic arm showed increased anterior tilt (p < 0.05) during arm elevation and lowering in self-selected plane compared to controls.
No difference in scapular upward rotation among neither arms, nor correlation between
scapular kinematics and MAL-30 were found (p > 0.05).
Interpretation
Individuals with chronic stroke showed bilateral scapular kinematics alterations.
However, these alterations are not correlated with paretic arm function.
