The P300-based brain-computer interface speller can provide motor independent communication to individuals with amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disorder that affects the motor system. P300 amplitude stability is critical for operation of the P300 speller. The P300 has good long-term stability, but to our knowledge, short-term habituation in the P300 speller has not been studied. In the current study, 15 participants: 8 ALS patients and 7 age-matched healthy volunteers (HVs), used 2 versions of P300 spellers, Face speller and Flash speller, each for 30 minutes. The ALS group performed as well as the HVs in both spellers and HVs did better with the Face speller than Flash speller while the ALS group performed equally well in both spellers. Neither intra-run P300 habituation nor inter-run P300 habituation was found. The P300 speller could be a reliable communication device for individuals with ALS.

使用基于 P300 的脑机接口拼写器时 P300 的习惯:肌萎缩侧索硬化患者与年龄匹配对照

基于 P300 的脑机接口拼写器可以为肌萎缩侧索硬化 (ALS) 患者提供独立于运动的交流,肌萎缩侧索硬化症是一种影响运动系统的进行性神经退行性疾病。P300 振幅稳定性对于 P300 拼写器的操作至关重要。P300 具有良好的长期稳定性,但据我们所知,尚未研究 P300 拼写器的短期习惯。在当前的研究中,15 名参与者:8 名 ALS 患者和 7 名年龄匹配的健康志愿者 (HV),使用了 2 个版本的 P300 拼写器、Face 拼写器和 Flash 拼写器,各使用 30 分钟。ALS 组在两个拼写器中的表现都与 HV 一样好,HVs 用 Face 拼写器比 Flash 拼写器表现得更好,而 ALS 组在两个拼写器中的表现同样出色。没有发现运行内 P300 习惯化和运行间 P300 习惯化。P300 拼写器可能是 ALS 患者的可靠通信设备。
