Short Foot Exercises as a Preventive Strategy for ACL Injury in Women with Dynamic Knee Valgus.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Dynamic knee valgus (DKV) is a well-established contributor to knee injuries, with women at higher risk. Traditional rehabilitation often emphasizes proximal muscle strengthening, but growing research suggests that foot and ankle dysfunction may play a critical role in DKV development. This study aimed to investigate the effects of a 6-week short foot exercise (SFE) program on the DKV angle, navicular drop, ankle dorsiflexion range of motion (DFROM), and proprioceptive acuity at the knee and ankle in women with DKV. Methods: This quasi-experimental study involved 28 female university students (aged 20-30 years) with DKV and excessive navicular drop, assigned to either an SFE group or a control group. The intervention group performed supervised SFE sessions 3 times per week for 6 weeks. Measurements taken before and after the intervention included DKV angle, navicular drop, ankle DFROM, and proprioceptive acuity at the knee and ankle. Appropriate parametric and nonparametric statistical tests (t-tests, analysis of covariance, Mann-Whitney U, and Wilcoxon test) were used based on data distribution. Results: After the intervention, the SFE group demonstrated significant improvements compared to the control group in DKV angle (adjusted mean difference = -4.0°, 95% CI: -6.0° to -2.1°, p = 0.001, d = 2.04), navicular drop (-4.2 mm, 95% CI: -5.4 to -2.9 mm, Conclusion: A structured 6-week SFE program effectively enhances foot posture, ankle mobility, and proprioceptive control, leading to reduced knee valgus in young women. These findings support the inclusion of distal kinetic chain exercises in rehabilitation programs aimed at correcting lower limb dysfunction and preventing knee injuries.
