The Jebsen Hand Function Test (JHFT) is a standardized assessment that has been used as a clinical outcome measure. To appropriately interpret the effects of an intervention on hand function (as measured by the JHFT), the extent to which this instrument shows significant practice effects must be quantified. The purpose of this study was to determine whether the JHFT is susceptible to within-session practice effects. The results showed that the dominant and nondominant hands significantly improved on the JHFT and many of its subtests over six consecutive trials. Although practice effects might complicate the interpretation of change due to intervention, we briefly relate our findings to emerging neuropsychological evidence that practice effects may indicate a person's motor learning potential or treatment responsiveness.
杰布森手功能测试（JHFT）是一种标准化评估，已被用作临床结果指标。为了恰当地解释干预对手功能的影响（通过JHFT测量），必须量化该工具显示出显著练习效应的程度。本研究的目的是确定JHFT是否易受会话内练习效应的影响。结果表明，在连续六次试验中，优势手和非优势手在JHFT及其许多子测试中均有显著改善。尽管练习效应可能会使因干预导致的变化解释复杂化，但我们简要地将我们的发现与新出现的神经心理学证据联系起来，即练习效应可能表明一个人的运动学习潜力或治疗反应性。
