Chronic ankle instability (CAI) is a common injury among athletes. Research has reported reduced dorsiflexion range of motion, impairment of proprioception, and decreased muscle strength of the ankle in people with CAI. The aim of this research was to examine the effects of 8-week core stability training on stable and unstable surfaces on ankle muscular strength, proprioception, and dorsiflexion range of motion (ROM) in athletes with CAI.
Thirty-six athletes with CAI (age 22.42 ± 2.76 years; height 169.11 ± 3.52 cm; weight 68.46 ± 2.75 kg) participated in this study. They were divided into three groups: unstable-surface group (UG) (n = 12), stable-surface group (SG) (n = 12), and control group (CG) (n = 12). The UG and SG performed the core stability exercise protocol for 8 weeks, 3 sessions per week. The CG received their usual care and daily activities. Outcomes were measured pre-sessions and post-sessions.
The peak torque showed significant increases in the UG and SG compared with the CG during plantar flexion, dorsiflexion, inversion, and eversion (P < 0.05). There were also significant increases in UG compared with SG (P < 0.05). The proprioception showed significant decreases in UG compared with SG and CG (P < 0.05). The dorsiflexion ROM showed significant increases in UG and SG compared with CG. There were also significant increases in UG compared with SG (P < 0.05).
It seems that core stability exercises on trampoline surface helps improve the measured parameters in athletes with ankle instability. Therefore, this type of training is recommended as a therapeutic option for Individuals with CAI.
慢性踝关节不稳定（CAI）是运动员常见的损伤。研究报告称，CAI 患者的背屈活动范围减小、本体感觉受损以及踝关节肌肉力量下降。本研究旨在探讨 8 周核心稳定性训练对 CAI 运动员稳定和不稳定表面踝关节肌肉力量、本体感觉和背屈活动范围（ROM）的影响。
36 名 CAI 运动员（年龄 22.42 ± 2.76 岁；身高 169.11 ± 3.52cm；体重 68.46 ± 2.75kg）参与了这项研究。他们被分为三组：不稳定表面组（UG）（n=12）、稳定表面组（SG）（n=12）和对照组（CG）（n=12）。UG 和 SG 每周进行 3 次核心稳定性练习，共 8 周。CG 接受常规护理和日常活动。在练习前后测量结果。
与 CG 相比，UG 和 SG 的足底屈肌、背屈肌、内翻和外翻时峰值扭矩均显著增加（P<0.05）。UG 与 SG 相比也有显著增加（P<0.05）。UG 的本体感觉与 SG 和 CG 相比显著降低（P<0.05）。UG 和 SG 的背屈 ROM 与 CG 相比均显著增加。UG 与 SG 相比也有显著增加（P<0.05）。
似乎在蹦床上进行核心稳定性训练有助于改善踝关节不稳定运动员的测量参数。因此，建议将这种训练作为 CAI 患者的一种治疗选择。
