振动反馈对康复来说是一个有用的工具。我们检查了它在肌张力障碍儿童中的使用，以了解它如何影响对标准康复反应不佳的人群的肌肉活动。我们预测，有比例的振动(即与肌肉活动直接或成反比的振动)会因为任务相关的感觉信息而增加对振动肌肉的使用，而非比例振动不会改变肌肉的使用。这项研究在11名肌张力障碍患者和14名对照身上进行。每个受试者在一维的双手肌肉控制任务中，在肌张力障碍较严重的二头肌(或对照组中的非优势臂)上经历了4种不同类型的振动。我们的结果表明，在肌张力障碍的儿童中，只有比例振动反馈可以在不改变整体表现的情况下偏向肌肉使用。我们相信，有比例的振动反馈可能在康复中发挥作用，以重新训练异常的肌肉模式。
Vibratory feedback can be a useful tool for rehabilitation. We examined its use in children with dystonia to understand how it affects muscle activity in a population that does not respond well to standard rehabilitation. We predicted scaled vibration (i.e. vibration that was directly or inversely proportional to muscle activity) would increase use of the vibrated muscle because of task-relevant sensory information, while non-scaled vibration would not change muscle use. The study was conducted on 11 subjects with dystonia and 14 controls. Each subject underwent 4 different types of vibration on the more dystonic biceps muscle (or non-dominant arm in controls) in a one-dimensional, bimanual myocontrol task. Our results showed that only scaled vibratory feedback could bias muscle use without changing overall performance in children with dystonia. We believe there may be a role in rehabilitation for scaled vibratory feedback to retrain abnormal muscle patterns.
