Sitting up and rising are basic daily activities that can become seriously impaired due to a stroke. This dysfunction can be a reason for limiting the ability to perform other daily activities. The aim of the study was to conduct functional and kinematic estimation of abnormalities of sitting down and getting up in people after a stroke.
Twenty-nine patients after stroke (mean age: 52.9 ± 7.8) and 29 healthy volunteers (mean age: 50.9 ± 7.4) were included in this study. The wireless sensors and functional tests, such as the 30-s Chair Stand Test (30CST) and The Five Times Sit-to-Stand Test (FTSST), were used to assess functionally and kinematically of the movement of getting up and sitting down. The force platform was used to assess the symmetry index (SI).
A significantly higher mean square error (MSE) was observed in the paretic limb compared to the control limb (p = 0.037) during sitting on a chair. A lower average angular velocity of the knee joint of the paretic limb compared to the non-paretic limb (p = 0.027) was observed while getting up from a chair. Stroke survivors needed more time to perform the FTSST test (p < 0.001) and performed fewer repetitions of getting up and sitting down in the 30CST test (p < 0.001) than healthy volunteers. Compared to the control group, more significant limb load asymmetry in the standing position was observed in the study group (p < 0.001).
The differences detected between stroke patients with hemiparesis and healthy individuals in the results of kinematic and functional tests allow for the direction of lower limb therapy in patients in the early period of post-stroke rehabilitation.
坐起和站起是基本的日常活动，中风后可能会严重受损。这种功能障碍可能是限制进行其他日常活动能力的一个原因。本研究的目的是对中风后患者坐下和站起异常进行功能和运动学评估。
本研究纳入了29名中风后患者（平均年龄：52.9±7.8岁）和29名健康志愿者（平均年龄：50.9±7.4岁）。使用无线传感器和功能测试，如30秒椅子站立测试（30CST）和五次坐立测试（FTSST），对坐起和坐下动作进行功能和运动学评估。使用测力平台评估对称指数（SI）。
在坐在椅子上时，与对照肢体相比，患侧肢体的均方误差（MSE）显著更高（p = 0.037）。从椅子上起身时，与非患侧肢体相比，患侧肢体膝关节的平均角速度更低（p = 0.027）。与健康志愿者相比，中风幸存者完成FTSST测试需要更多时间（p < 0.001），并且在30CST测试中坐起和坐下的重复次数更少（p < 0.001）。与对照组相比，研究组在站立位观察到更明显的肢体负荷不对称（p < 0.001）。
在运动学和功能测试结果中发现的偏瘫中风患者与健康个体之间的差异，为中风后康复早期患者的下肢治疗指明了方向。
