Balance impairment could occur due to weakness of the core muscles in stroke patients.
To investigate the association between functional ability, including trunk balance and core muscle thickness using ultrasonography in subacute hemiplegic stroke patients.
The muscle thickness of the anterior and posterior trunk muscles was measured using ultrasonography. For the evaluation of trunk balance, trunk impairment scale and Berg balance scale (BBS) were used. The functional ambulatory scale (FAS), timed up-and-go test, 10 m gait velocity, functional reach (FR), and functional independence measure were also assessed for functional ability.
Overall, 41 patients with subacute hemiplegic stroke were included. Partial correlation analysis showed that posterior trunk muscle thickness was significantly correlated with BBS, FAS, and FR. As for the paralytic side, the posterior trunk muscle thickness of both paretic and nonparetic sides presented a significant relationship with BBS, FAS, and FR. The quadratus lumborum (QL) thickness of both sides showed a significant relationship with BBS, FAS, and FR.
The thickness of the posterior trunk muscles, especially the QL, on both the paretic and nonparetic sides, was significantly related with the functional ability after stroke. The exercise program of core posterior trunk muscles closely related with functional ability would be helpful to improve trunk balance and ambulatory function in subacute stroke patients.
中风患者核心肌肉力量减弱可能导致平衡受损。
探讨亚急性偏瘫中风患者的功能能力（包括躯干平衡）与使用超声测量的核心肌肉厚度之间的关联。
使用超声测量躯干前后肌肉的厚度。为评估躯干平衡，采用躯干损伤量表和伯格平衡量表（BBS）。还评估了功能步行量表（FAS）、计时起立行走测试、10米步态速度、功能性伸展（FR）和功能独立性测量以评估功能能力。
总共纳入了41例亚急性偏瘫中风患者。偏相关分析表明，躯干后肌厚度与BBS、FAS和FR显著相关。对于患侧，患侧和非患侧的躯干后肌厚度均与BBS、FAS和FR呈现显著关系。两侧腰方肌（QL）厚度与BBS、FAS和FR均呈现显著关系。
患侧和非患侧的躯干后肌厚度，尤其是QL厚度，与中风后的功能能力显著相关。与功能能力密切相关的核心躯干后肌锻炼计划将有助于改善亚急性中风患者的躯干平衡和步行功能。
