Providing effective feedback to patients in a rehabilitation training program is essential. As technologies are being developed to support patient training, they need to be able to provide the users with feedback on their performance. As there are various aspects on which feedback can be given (e.g., task success and presence of compensatory movements), it is important to ensure that users are not overwhelmed by too much information given too frequently by the assistive technology. We created a rule-based set of guidelines for the desired hierarchy, timing, and content of feedback to be used when stroke patients train with an upper-limb exercise platform which we developed. The feedback applies to both success on task completion and to the execution of compensatory movements, and is based on input collected from clinicians in a previous study. We recruited 11 stroke patients 1-72 months from injury onset. Ten participants completed the training; each trained with the rehabilitation platform in two configurations: with motor feedback (MF) and with no motor feedback (control condition) (CT). The two conditions were identical, except for the feedback content provided: in both conditions they received feedback on task success; in the MF condition they also received feedback on making undesired compensatory movements during the task. Participants preferred the configuration that provided feedback on both task success and quality of movement (MF). This pilot experiment demonstrates the feasibility of a system providing both task-success and movement-quality feedback to patients based on a decision tree which we developed.
在康复训练项目中向患者提供有效的反馈至关重要。随着支持患者训练的技术不断发展,这些技术需要能够向用户提供其表现的反馈。由于可以给出反馈的方面多种多样(例如,任务成功与否以及是否存在代偿性动作),因此重要的是要确保辅助技术不会因过于频繁地提供过多信息而使用户应接不暇。我们为使用我们开发的上肢运动平台进行训练的中风患者创建了一套基于规则的指南,用于确定反馈的期望层次结构、时机和内容。该反馈适用于任务完成的成功情况以及代偿性动作的执行情况,并且基于之前一项研究中从临床医生那里收集到的输入信息。我们招募了11名中风患者,他们在受伤后1至72个月。10名参与者完成了训练;每个人都以两种配置使用康复平台进行训练:一种是有运动反馈(MF),另一种是无运动反馈(对照条件,CT)。这两种条件除了提供的反馈内容不同外完全相同:在两种条件下他们都收到关于任务成功的反馈;在MF条件下,他们还收到关于在任务期间做出不期望的代偿性动作的反馈。参与者更喜欢能同时提供任务成功和运动质量反馈的配置(MF)。这项初步实验证明了基于我们开发的决策树为患者提供任务成功和运动质量反馈的系统的可行性。
