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.
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.
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).
Individuals with chronic stroke showed bilateral scapular kinematics alterations. However, these alterations are not correlated with paretic arm function.
中风可导致肩胛骨运动改变，这可能会限制日常生活活动能力。目的是评估慢性中风患者的肩胛骨运动学及其与患侧手臂功能的相关性。
对34名个体（慢性中风患者=17名；对照组=17名）在肩胛骨平面和自选平面进行手臂抬高和放下以及梳理头发过程中的肩胛骨运动学进行评估。通过运动活动日志（MAL-30）评估患侧手臂进行日常生活活动的情况。比较患侧和非患侧手臂以及对照组之间的肩胛骨运动学。还验证了肩胛骨运动学与MAL-30之间的相关性。
与对照组相比，在肩胛骨平面手臂放下过程中以及在自选平面手臂抬高和放下过程中，患侧和非患侧手臂的肩胛骨内旋增加（p<0.05）。与对照组相比，在梳理头发过程中患侧手臂的内旋也增加（p<0.05）。与对照组相比，在梳理头发活动中手臂抬高时以及在肩胛骨平面和自选平面手臂抬高和放下过程中，患侧手臂的肩胛骨前倾增加（p<0.05）。与对照组相比，在自选平面手臂抬高和放下过程中，非患侧手臂的前倾增加（p<0.05）。未发现两侧肩胛骨上旋有差异，也未发现肩胛骨运动学与MAL-30之间存在相关性（p>0.05）。
慢性中风患者表现出双侧肩胛骨运动学改变。然而，这些改变与患侧手臂功能无关。
