Distribution of body weight on the two legs while rising and sitting down was examined in 42 subacute stroke patients and 16 healthy adults during both spontaneous movement and following instruction directed at even weight distribution. Vertical floor reaction forces were measured by two force plates. There was a difference between patients and controls in the tested motor tasks--the patients favoured their nonparetic leg. However, body weight distribution was less asymmetric when patients tried to rise and sit down evenly compared to spontaneous rising/sitting down (p less than 0.001). Patients' own estimation of distribution of body weight documented on a visual analogue scale, correlated with actual body weight distribution while rising (rs = 0.36) but not while sitting down. To motivate stroke patients to pay attention to their ability to distribute body weight evenly while rising and sitting down and to create and use adequate self-reports seems a necessary commitment in a rehabilitation programme in order to avoid the learned nonuse syndrome.
在42例亚急性中风患者和16名健康成年人中，研究了他们在自发运动以及按照均匀体重分布的指令进行起身和坐下动作时双腿的体重分布情况。使用两个测力板测量垂直地面反作用力。在测试的运动任务中，患者与对照组存在差异——患者更倾向于使用非瘫痪侧腿。然而，与自发起身/坐下相比，当患者试图均匀起身和坐下时，体重分布的不对称性较小（p<0.001）。患者在视觉模拟量表上对体重分布的自我估计，与起身时的实际体重分布相关（rs = 0.36），但与坐下时无关。为了避免习得性废用综合征，在康复计划中，激励中风患者关注他们在起身和坐下时均匀分配体重的能力，并创建和使用适当的自我报告似乎是一项必要的工作。
