The aim of this study was to determine whether varying the predetermined malaise level at which provocative motion challenges were stopped would affect the habituation rate. At the rate of 2 per day, 21 motion challenges were delivered, stopping either at initial symptoms or at moderate nausea, on a cross-over design randomized between subjects (n = 20). The cross-coupled motion challenge had an incrementing profile of rotational velocity from 2-90 degrees.s-1 in steps of 2 degrees.s-1 every 30 s, with 8 head movements per 30 s, of approximately 45 degrees. The number of head movements tolerated before the onset of nausea increased over the 21 challenges, but the effects of the treatment variation on habituation were not significant. The number of motion challenges, rather than the severity of malaise level achieved, was the more important factor determining habituation.
本研究的目的是确定改变激发性运动挑战停止时预先设定的不适水平是否会影响习惯化率。以每天2次的频率进行21次运动挑战，在初始症状或中度恶心时停止，采用受试者间交叉随机设计（n = 20）。交叉耦合运动挑战具有递增的旋转速度曲线，从2度·秒⁻¹到90度·秒⁻¹，每30秒增加2度·秒⁻¹，每30秒有8次头部运动，幅度约为45度。在21次挑战中，恶心发作前耐受的头部运动次数增加，但治疗变化对习惯化的影响不显著。决定习惯化的更重要因素是运动挑战的次数，而非所达到的不适水平的严重程度。
