The objective of this systematic review was to evaluate the association between ankle dorsiflexion (ADF) and dynamic knee valgus (DKV).
Electronic searches were conducted in MEDLINE, EMBASE, CINAHL and SPORTDiscus. A modified Downs and Black checklist was used for quality assessment and meta-analysis was performed to compare standardised mean differences (SMD) of ADF.
Seventeen studies met the inclusion criteria. Meta-analysis showed that reduced ADF is associated with participants presenting with DKV compared to controls (SMD -0.65, 95% CI -0.88 to -0.41). Subgroup analysis showed consistent results regarding different forms of ADF measurement; restriction in ADF measured in weight-bearing position (SMD -1.25, 95% CI -2.24 to -0.25), non-weight-bearing with knee flexed (SMD -0.56, 95% CI -0.97 to -0.16) or non-weight-bearing with knee extended (SMD -0.54, 95% CI -0.80 to -0.28) was significantly associated with DKV.
The meta-analysis results provide evidence that reduced ADF is correlated with DKV. The assessment of ADF in the clinical setting is important, as it may be related to harmful movement patterns of the lower limbs.
本系统评价的目的是评估踝关节背屈（ADF）与动态膝外翻（DKV）之间的关联。
在MEDLINE、EMBASE、CINAHL和SPORTDiscus数据库中进行电子检索。采用改良的唐斯和布莱克检查表进行质量评估，并进行荟萃分析以比较ADF的标准化均数差（SMD）。
17项研究符合纳入标准。荟萃分析表明，与对照组相比，ADF降低与出现DKV的参与者相关（SMD -0.65，95%CI -0.88至-0.41）。亚组分析显示，关于不同形式的ADF测量结果一致；负重位测量的ADF受限（SMD -1.25，95%CI -2.24至-0.25）、屈膝非负重（SMD -0.56，95%CI -0.97至-0.16）或伸膝非负重（SMD -0.54，95%CI -0.80至-0.28）与DKV显著相关。
荟萃分析结果提供了证据，表明ADF降低与DKV相关。在临床环境中评估ADF很重要，因为它可能与下肢有害的运动模式有关。
