Long-term effects of auditory kinetic feedback on relearned symmetrical body weight distribution while rising and sitting down were studied in stroke patients. Thirty patients were re-tested on average 33 months after having trained with and without auditory feedback. Body weight distribution on the legs was measured with two force plates. At re-test there was a decrease from 48% to 39% of body weight distribution (%BWD) on the paretic leg in rising and in sitting down in the patients in the auditory feedback group (p < 0.001). In the control group the decrease was from 44 to 39% BWD on the paretic leg (p < 0.05) in rising and from 44 to 42% BWD (n.s.) in sitting down. The symmetrical body-weight distribution, acquired after auditory feedback training, was not consistent over time. Movement time, however, was significantly reduced in the auditory feedback group (p < 0.05). Possible reasons for the findings are discussed.
研究了听觉动力学反馈对中风患者起身和坐下时重新学习到的对称体重分布的长期影响。30名患者在接受有或没有听觉反馈的训练后，平均33个月进行了重新测试。使用两个测力板测量腿部的体重分布。在重新测试时，听觉反馈组患者在起身和坐下时，患侧腿的体重分布（%BWD）从48%下降到39%（p < 0.001）。在对照组中，起身时患侧腿的%BWD从44%下降到39%（p < 0.05），坐下时从44%下降到42%（无统计学意义）。听觉反馈训练后获得的对称体重分布在一段时间内并不一致。然而，听觉反馈组的运动时间显著缩短（p < 0.05）。文中讨论了这些研究结果的可能原因。
