作者训练了21名参与者，使用阻断和混合暴露右侧滑动，然后使他们意外地在未经训练的左侧滑动。作者在1周、2周、1个月和4个月时对右滑和左滑的参与者进行了重新测试。作者发现，第一次未经训练的左滑的前滑稳定性得到改善，并且显著大于第一次右滑，这可能是福尔斯发生率从30%降至10%的原因。滑后稳定性和基底的支持（BOS）的滑动速度类似的第一个右滑，远低于最后一个右滑。增加前和后滑稳定性和BOS滑移速度在左滑移导致减少向后平衡损失（BLOB）从95%的初始左滑移到60%和25%的第一次和第三次复试会议，分别。相比之下，在同一次复试中，右侧的BLOB保持在恒定的± 40%水平。结果表明，部分立即转移和潜在的转移。
The authors trained 21 participants by using blocked-and-mixed exposure to right-side slips and then caused them to slip unexpectedly on the untrained left side. Authors retested participants with a right slip and a left slip at 1 week, 2 weeks, 1 month, and 4 months. The authors found that preslip stability on the first untrained left slip improved and was significantly greater than that on the first right slip, which probably contributed to the reduction in incidence of falls from ∼30% to ∼10%. Postslip stability and base of support (BOS) slip velocity were similar to those on the first right slip and much lower than those on the last right slip. Increases in pre- and postslip stabilities and BOS slip velocity during the left slip led to reductions in backward balance loss (BLOB) from ∼95% on initial left slip to ∼60% and to ∼25% on the 1st and 3rd retest sessions, respectively. In contrast, BLOB remained at a constant ∼40% level on the right slip of the same retest sessions. The results indicate a partial immediate transfer and a possible latent transfer.
