The possibility of enabling two adults with acquired brain injury and profound multiple disabilities to use microswitch-based technology to attain preferred environmental stimuli on their own was assessed. Each of the participants was provided with two microswitches that could be activated by right and left head-turning or head-bending responses. The microswitches were introduced sequentially according to a multiple probe design across microswitches (responses) and allowed access to different sets of auditory or visual stimuli. Eventually, the two microswitches were made available simultaneously. Sessions lasted 5 min. Each participant learned to use the two microswitches successfully and maintained consistent levels of responding when they were simultaneously available. During this phase, both participants showed large within-session variations in their right and left response frequencies, with one of them showing an overall prevalence of the left-side response. The importance of assistive technology within programs for persons with acquired brain injury and multiple disabilities is discussed.
评估了两名患有后天性脑损伤和严重多重残疾的成年人使用基于微开关的技术来自主获得他们喜欢的环境刺激的可能性。为每个参与者提供了两个微开关，可以通过向右和向左转头或头倾斜的反应来激活。根据微开关（反应）和允许访问不同的听觉或视觉刺激集的多探针设计，依次引入微开关。最终，同时提供了两个微开关。每个会话持续 5 分钟。两名参与者都成功地学会了使用两个微开关，并且当它们同时可用时，保持了一致的反应水平。在这个阶段，两名参与者在他们的左右反应频率上都表现出了很大的会话内变化，其中一个人表现出了左侧反应的总体优势。讨论了辅助技术在后天性脑损伤和多重残疾患者的治疗计划中的重要性。
