Chronic ankle instability (CAI) describes the residual symptoms present after repetitive ankle sprains. Current rehabilitation programs in the high school population focus on a multistation approach or general lower-extremity injury-prevention program. Specific rehabilitation techniques for CAI have not been established.
To determine the effectiveness of a 4-wk biomechanical ankle platform system (BAPS) board protocol on the balance of high school athletes with CAI.
Randomized control trial.
Athletic training facility.
Twenty-two high school athletes with "giving way" and a history of ankle sprains (ie, CAI) were randomized into a rehabilitation (REH) (166.23 ± 0.93 cm, 67.0 ± 9.47 kg, 16.45 ± 0.93 y) or control (CON) (173.86 ± 8.88 cm, 84.51 ± 21.28 kg, 16.55 ± 1.29 y) group.
After baseline measures, the REH group completed a progressive BAPS rehabilitation program (3 times/wk for 4 wk), whereas the CON group had no intervention. Each session consisted of 5 trials of clockwise/counterclockwise rotations changing direction every 10 s during each 40-s trial. After 4 wk, baseline measurements were repeated.
Dependent measures included longest time (time-in-balance test), average number of errors (foot lift test), average reach distance (cm) normalized to leg length for each reach direction (Star Excursion Balance Test [SEBT]), and fastest time (side hop test [SHT]).
Significant group-by-time interactions were found for TIB (F = 9.89, P = .005), FLT (F = 41.18, P < .001), SEBT-anteromedial (F = 5.34, P = .032), SEBT-medial (F = 7.51, P = .013), SEBT-posteromedial (F = 12.84, P = .002), and SHT (F = 7.50, P = .013). Post hoc testing showed that the REH group improved performance on all measures at posttest, whereas the CON group did not.
A 4-wk BAPS rehabilitation protocol improved balance in high school athletes suffering from CAI. These results can allow clinicians to rehabilitate in a focused manner by using 1 rehabilitation tool that allows benefits to be accomplished in a shorter time.
慢性踝关节不稳（CAI）描述的是反复踝关节扭伤后出现的残留症状。目前针对高中生群体的康复计划侧重于多站式方法或一般的下肢损伤预防计划。CAI的具体康复技术尚未确立。
确定为期4周的生物力学踝关节平台系统（BAPS）板方案对患有CAI的高中运动员平衡能力的有效性。
随机对照试验。
运动训练设施。
22名有“打软腿”现象且有踝关节扭伤史（即CAI）的高中运动员被随机分为康复（REH）组（身高166.23±0.93厘米，体重67.0±9.47千克，年龄16.45±0.93岁）和对照组（CON）（身高173.86±8.88厘米，体重84.51±21.28千克，年龄16.55±1.29岁）。
在进行基线测量后，REH组完成一个渐进式BAPS康复计划（每周3次，共4周），而CON组不进行干预。每次训练包括在每个40秒的试验中，每10秒顺时针/逆时针旋转并改变方向，共进行5次试验循环。4周后，重复进行基线测量。
相关测量指标包括最长时间（平衡时间测试）、平均错误次数（抬脚测试）、每个伸展方向相对于腿长归一化后的平均伸展距离（厘米）（星形偏移平衡测试[SEBT]）以及最快时间（单腿跳测试[SHT]）。
在平衡时间（TIB）（F = 9.89，P = .005）、抬脚测试（FLT）（F = 41.18，P < .001）、SEBT-前内侧方向（F = 5.34，P = .032）、SEBT-内侧方向（F = 7.51，P = .013）、SEBT-后内侧方向（F = 12.84，P = .002）和单腿跳测试（SHT）（F = 7.50，P = .013）方面发现了显著的组×时间交互作用。事后检验表明，REH组在测试后所有测量指标上的表现均有所改善，而CON组则没有。
为期4周的BAPS康复方案改善了患有CAI的高中运动员的平衡能力。这些结果可以让临床医生通过使用一种康复工具进行有针对性的康复，从而在更短的时间内取得康复效果。
