Patient NG is the first reported case of lower-limb 'self-touch enhancement' following stroke. Mobility problems prevented NG from reaching to touch her foot, thus we used a self-touch rubber-hand paradigm to mimic the conditions of self-administered touch. With vision precluded, NG administered stimulation to a prosthetic limb while the Examiner administered synchronous stimulation to NG's affected left foot. NG detected all stimulation administered with our self-touch paradigm, whereas in the control condition (with NG not involved in administering stimulation), NG had failed to detect one-third of Examiner-administered stimulation. When mobility problems are a barrier to investigating self-touch enhancement, the self-touch paradigm can be used to demonstrate residual tactile sensation following stroke.
患者NG是首例被报道的中风后下肢“自我触摸增强”病例。行动不便使NG无法触摸到自己的脚，因此我们采用了自我触摸橡胶手范式来模拟自我触摸的情况。在视觉被阻断的情况下，NG对假肢进行刺激，同时检查者对NG受影响的左脚进行同步刺激。NG能检测到我们自我触摸范式下施加的所有刺激，而在对照条件下（NG不参与施加刺激），NG未能检测到检查者施加刺激的三分之一。当行动不便成为研究自我触摸增强的障碍时，自我触摸范式可用于证明中风后残留的触觉。
