A force platform with an auditory output consisting of two electronic balances was used to reinforce symmetrical body-weight distribution in stroke patients. Forty patients randomly assigned to an experimental group or a control group practised rising and sitting down for 15 min, thrice daily, 5 days a week for 6 weeks. The experimental group but not the control group received ground reaction force feedback through the auditory output. Vertical ground reaction forces under each foot were measured with two force plates. Mean difference in improvement of body weight distribution on the paretic leg was 13.2 +/- 10.7 (M, SD) per cent total body weight in the experimental group and 5.1 +/- 6.7 per cent in the control group in rising (p < 0.01) and 12.7 +/- 7.5 per cent total body weight and 4.6 +/- 6.6 per cent in sitting down tests (p < 0.001). The patients in the experimental group achieved in average close to a symmetrical body-weight distribution while rising and sitting down. Improvements in physical performance and sit-stand tests were greater in the experimental group (p < 0.05 and p < 0.01, respectively). No differences were seen in improvement in performance of activities of daily living. Symmetry in body-weight distribution in rising and sitting down correlated with high scores in physical performance, motor function in rising, and with functional ability.
使用一个由两个电子天平组成且带有听觉输出的测力平台，来强化中风患者的对称体重分布。40名患者被随机分为实验组和对照组，他们每天进行3次起立和坐下练习，每次15分钟，每周练习5天，共持续6周。实验组通过听觉输出接收地面反作用力反馈，而对照组则没有。使用两个测力板测量每只脚下的垂直地面反作用力。在起立测试中，实验组患侧腿体重分布改善的平均差异为总体重的13.2±10.7（均值，标准差）%，对照组为5.1±6.7%（p<0.01）；在坐下测试中，实验组为总体重的12.7±7.5%，对照组为4.6±6.6%（p<0.001）。实验组患者在起立和坐下时平均实现了接近对称的体重分布。实验组在身体机能和坐立测试中的改善更大（分别为p<0.05和p<0.01）。在日常生活活动表现的改善方面未观察到差异。起立和坐下时体重分布的对称性与身体机能高分、起立运动功能以及功能能力相关。
