The effects of increased response effort on levels of hand mouthing, leisure engagement, and adaptive elbow flexion were investigated with 2 individuals who had been diagnosed with profound disabilities. Arm restraints designed to alter the amount of physical effort necessary to engage in hand mouthing were used. Results indicated that the treatment strategy reduced levels of hand mouthing but produced only small to moderate reductions in levels of leisure engagement and adaptive elbow flexion. At follow-up, the effects of increased response effort on hand mouthing and leisure engagement were maintained for both participants; however, the restraints were associated with substantial reductions in adaptive elbow flexion for 1 participant.
研究了增加反应努力对手部放入口中行为、休闲活动参与度和适应性肘部弯曲程度的影响，研究对象为两名被诊断为重度残疾的个体。使用了旨在改变手部放入口中行为所需体力的手臂约束装置。结果表明，该治疗策略降低了手部放入口中行为的程度，但仅使休闲活动参与度和适应性肘部弯曲程度有小到中度的降低。在随访中，增加反应努力对手部放入口中行为和休闲活动参与度的影响在两名参与者中均得以维持；然而，对于一名参与者，约束装置与适应性肘部弯曲的大幅降低有关。
