Lateral ankle sprain (LAS) is one of the most common injuries incurred during sporting activities, and effective rehabilitation programs for this condition are challenging to develop. The purpose of this research was to compare the effect of 6 weeks of balance training on either a mini-trampoline or a dura disc on postural sway and to determine if the mini-trampoline or the dura disc is more effective in improving postural sway. Twenty subjects (11 men, 9 women) with a mean age of 25.4 +/- 4.2 years were randomly allocated into a control group, a dura disc training (DT) group, or a mini-trampoline (MT) group. Subjects completed 6 weeks of balance training. Postural sway was measured by subjects performing a single limb stance on a force plate. The disbursement of the center of pressure was obtained from the force plate in the medial-lateral and the anterior-posterior sway path and was subsequently used for pretest and posttest analysis. After the 6-week training intervention, there was a significant (p < 0.05) difference in postural sway between pre- and posttesting for both the MT (pretest = 56.8 +/- 20.5 mm, posttest = 33.3 +/- 8.5 mm) and DT (pretest = 41.3 +/- 2.6 mm, posttest = 27.2 +/- 4.8 mm) groups. There was no significant (p > 0.05) difference detected for improvements between the MT and DT groups. These results indicate that not only is the mini-trampoline an effective tool for improving balance after LAS, but it is equally as effective as the dura disc.
外侧踝关节扭伤（LAS）是体育活动中最常见的损伤之一，针对这种情况制定有效的康复计划具有挑战性。本研究的目的是比较在迷你蹦床或硬碟上进行6周平衡训练对姿势摇摆的影响，并确定迷你蹦床或硬碟在改善姿势摇摆方面是否更有效。20名受试者（11名男性，9名女性），平均年龄25.4 +/- 4.2岁，被随机分为对照组、硬碟训练（DT）组或迷你蹦床（MT）组。受试者完成了6周的平衡训练。姿势摇摆通过受试者在测力板上进行单腿站立来测量。压力中心的分布是从测力板在内外侧和前后摇摆路径中获得的，随后用于测试前和测试后的分析。经过6周的训练干预后，MT组（测试前=56.8 +/- 20.5毫米，测试后=33.3 +/- 8.5毫米）和DT组（测试前=41.3 +/- 2.6毫米，测试后=27.2 +/- 4.8毫米）在测试前和测试后的姿势摇摆上存在显著差异（p < 0.05）。MT组和DT组在改善方面没有检测到显著差异（p > 0.05）。这些结果表明，迷你蹦床不仅是LAS后改善平衡的有效工具，而且与硬碟同样有效。
