About 15-60% of individuals with ankle sprains may develop functional ankle instability (FAI), which is characterised by ankle pain, decreased muscle strength, limited range of motion, and impaired balance, causing a decline in social activity and quality of life. However, the relationship between those characters is still unclear. This study aimed to investigate whether a relationship existed between ankle pain, active range of motion (AROM), strength and balance and if ankle pain, AROM and strength can predict balance in individuals with FAI.
Seventy-seven subjects (46 males; 31 females) with unilateral FAI participated in this study. Ankle pain was measured by the visual analogue scale (VAS), ankle AROM was measured using a universal goniometer, ankle strength was measured using a handheld dynamometer, the static balance was measured by the Time in Balance Test (TBT) and the dynamic balance was measured by the modified Star Excursion Balance Test (mSEBT). Pearson product-moment correlations were used to determine the correlations between ankle pain, AROM, strength and balance. Multiple linear regressions were used to investigate if ankle pain, AROM and strength can predict balance in individuals with FAI.
VAS and AROM-plantarflexion predicted 25.6% of the TBT (f = 0.344, P < 0.001). AROM-dorsiflexion predicted 24.6% of the mSEBT-anterior reach (f = 0.326, P < 0.001). VAS, AROM-plantarflexion and strength-plantarflexion predicted 33.5% of the mSEBT-posteromedial reach (f = 0.504, P < 0.001). AROM-plantarflexion and strength-plantarflexion predicted 28.2% of the mSEBT-posterolateral reach (f = 0.393, P < 0.001).
This study shows that ankle plantarflexion strength, AROM of dorsiflexion and plantarflexion and pain are predictors of balance in individuals with FAI. These factors could be considered in the rehabilitation of FAI.

约 15-60%的踝关节扭伤患者可能会出现功能性踝关节不稳(FAI),其特征为踝关节疼痛、肌力下降、活动范围受限和平衡能力受损,从而导致社交活动和生活质量下降。然而,这些特征之间的关系尚不清楚。本研究旨在探讨 FAI 患者的踝关节疼痛、主动活动度(AROM)、力量和平衡之间是否存在关系,以及踝关节疼痛、AROM 和力量是否可以预测平衡。
本研究纳入了 77 名单侧 FAI 患者(46 名男性;31 名女性)。采用视觉模拟评分法(VAS)评估踝关节疼痛,使用通用量角器测量踝关节 AROM,使用手持测力计测量踝关节力量,采用平衡测试时间(TBT)评估静态平衡,采用改良星形伸展平衡测试(mSEBT)评估动态平衡。采用皮尔逊积差相关分析评估踝关节疼痛、AROM、力量和平衡之间的相关性。采用多元线性回归分析评估 FAI 患者中,踝关节疼痛、AROM 和力量是否可以预测平衡。
VAS 和 AROM-跖屈预测 TBT 的 25.6%(f=0.344,P<0.001)。AROM-背屈预测 mSEBT-前向延伸的 24.6%(f=0.326,P<0.001)。VAS、AROM-跖屈和跖屈力量预测 mSEBT-后内侧延伸的 33.5%(f=0.504,P<0.001)。AROM-跖屈和跖屈力量预测 mSEBT-后外侧延伸的 28.2%(f=0.393,P<0.001)。
本研究表明,FAI 患者的踝关节跖屈肌力、背屈和跖屈 AROM 以及疼痛是平衡的预测因素。这些因素可在 FAI 的康复中加以考虑。
