People who use wheelchairs are at risk for developing pressure sores. Regular pressure relief, in the form of a wheelchair push-up, is one way to reduce the likelihood of pressure sores. We examined the effects of antecedent (i.e., instructions, audible prompts) and consequent (i.e., alarm avoidance) events on wheelchair push-ups, using a multiple baseline analysis with 2 participants with spina bifida. Results suggest that the combined procedure was more effective than either antecedent or consequent events alone, and there is some evidence suggesting maintenance of effects over time.
使用轮椅的人有发生压疮的风险。定期进行减压，如轮椅撑起，是降低压疮发生可能性的一种方法。我们使用多基线分析，对2名脊柱裂患者进行研究，考察了先行事件（即指令、听觉提示）和后续事件（即避免警报）对轮椅撑起的影响。结果表明，联合程序比单独的先行事件或后续事件更有效，并且有一些证据表明效果会随时间持续。
