CS Home Training data.xlsx

After baseline measurements in-lab, participants were sent home to train for several months (subacute (SA): 4.9±0.6 months [mean ± SD]; chronic (CH): 6.8±4.0 months). They used their personal computers with a chin/forehead-rest provided by the lab, which they were instructed to position 42cm away from their display during training. Participants performed 300 trials of their assigned training tasks (Static, Motion or Flicker) per location per day, at least five days per week, and they emailed their data log files back to the lab for analysis every week. During home training sessions, they were instructed to stay fixated on the fixation spot and warned that inadequate fixation accuracy could limit recovery.Session thresholds were calculated by fitting a Weibull function with a 72.5 percent correct performance threshold criterion. After participants’ thresholds improved consistently for at least 20 sessions, we moved their training stimulus 1˚ deeper into the blind field along the x-axis (Cartesian coordinate space). Because the diameter of the stimulus is 2.5 ˚, the new training location had ~80% overlap with the original training location. Once participants trained for about 4 months, with at least one improved location (defined as consistently good contrast thresholds at that location), they were brought back to the lab, and performance at all home-trained locations was verified with eye tracker-enforced fixation control. We aimed for a similar number of training sessions at the blind-field locations of interest before scheduling people to return for in-lab performance verification. However, the amount of time elapsed until the return visit did vary, as it was affected by the individual’s rate of improvement, their work/family schedules, and ability to travel to our single study site (participants originated from across the entire United States and Canada). All participants were best corrected using glasses or contact lenses during testing and training. The Research Subjects Review Board approved study procedures at the University of Rochester, which were conducted as per the Declaration of Helsinki, with written informed consent obtained from each participant, and participation was voluntary.在实验室完成基线测量后，受试者被带回家进行数月训练（亚急性组（subacute, SA）：4.9±0.6个月[均值±标准差]；慢性组（chronic, CH）：6.8±4.0个月）。受试者使用实验室提供的下颌/前额托架搭配个人电脑开展训练，并被要求在训练过程中将设备调整至距显示器42厘米的位置。受试者每日需在每个训练位点完成300次指定训练任务（静态任务、运动任务或闪烁任务），每周训练至少5天，并每周通过邮件将数据日志文件发送至实验室以供分析。在家训练期间，受试者需始终注视注视点，且被提醒若注视精度不足可能会影响康复效果。 通过拟合威布尔函数（Weibull function）并以72.5%正确率作为性能阈值标准，计算得到各次训练的阈值。当受试者的阈值连续至少20个训练周期持续改善后，我们将训练刺激物沿笛卡尔坐标系（Cartesian coordinate space）的x轴向视野盲区深处移动1°。由于刺激物直径为2.5°，新训练位点与原训练位点的重叠度约为80%。当受试者累计训练约4个月，且至少有一个训练位点的阈值得到改善（定义为该位点的对比度阈值持续处于良好水平）后，我们将其召回实验室，并通过眼动仪强制注视控制，验证其所有在家训练位点的性能表现。 在安排受试者返回实验室进行性能验证前，我们尽量确保其在目标盲区位点完成相近次数的训练。但受试者返回实验室的间隔时长存在差异，这受到个体康复速度、工作/家庭日程以及前往我们唯一研究站点的出行能力的影响——受试者来自美国和加拿大全境。所有受试者在测试与训练期间均通过眼镜或隐形眼镜实现最佳矫正视力。本研究的所有流程均经罗切斯特大学研究受试者审查委员会（Research Subjects Review Board）批准，遵循《赫尔辛基宣言》（Declaration of Helsinki）开展，且已获得每位受试者的书面知情同意，参与本研究完全自愿。
