This study was a further evaluation of microswitch clusters (combinations of two microswitches) to improve adaptive responding together with correct head position in two persons with multiple disabilities. The two participants were 19.7 and 6.6 yr. old and had profound intellectual disabilities, spastic tetraparesis, and visual impairment. They were initially taught an adaptive hand response that activated a pressure microswitch and produced favorite stimulation. Thereafter, their performance of the hand response produced favorite stimulation only when it was combined with a correct head position (detected through a mercury microswitch). Analysis showed that both participants increased the frequency of the hand response and, subsequently, the percentage of times they emitted this response in combination with correct (upright) head position. In essence, they were able to coordinate constructive occupation with exercise of appropriate posture. Performance was maintained at a 2-mo. postintervention check.
本研究进一步评估了微动开关组合（两个微动开关的组合），以改善两名多重残疾人士的适应性反应以及正确的头部姿势。两名参与者分别为19.7岁和6.6岁，患有严重智力残疾、痉挛性四肢瘫痪和视力障碍。最初教他们一种适应性手部反应，该反应会激活一个压力微动开关并产生喜爱的刺激。此后，他们的手部反应只有在与正确的头部姿势（通过水银微动开关检测）相结合时才会产生喜爱的刺激。分析表明，两名参与者都增加了手部反应的频率，随后，他们将这种反应与正确（直立）头部姿势相结合的次数百分比也增加了。从本质上讲，他们能够将建设性活动与适当姿势的锻炼协调起来。干预后2个月的检查中，表现得以维持。
