Restoring Biomechanical Gait Function with Ultrasound-Guided Acupotomy for Post-Stroke Equinovarus Foot: Two Case Reports and a Protocol (A CARE- and SPIRIT-Compliant Study).
Article in Life (Basel, Switzerland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPost-stroke equinovarus foot (EVF) impairs gait stability, increases the risk of secondary injuries, and contributes to elevated healthcare costs. However, effective targeted interventions for EVF remain limited. PATIENT CONCERNS: Two patients with chronic EVF-a 63.5-year-old male (9.7 months post-stroke) and a 35.7-year-old female (24.5 months post-stroke)-presented with ankle deformity, gait asymmetry, and impaired balance, all of which interfered with daily activities. INTERVENTION AND OUTCOMES: Both patients underwent ultrasound-guided acupotomy targeting spastic ankle muscles, administered over four sessions within two weeks. A quantitative gait analysis revealed substantial improvements in step length ratios (Case 1: 0.61 → 0.86; Case 2: 0.67 → 0.88), as well as enhancements in walking velocity, lateral symmetry, postural balance, and Modified Ashworth Scale scores. No adverse events were reported. Protocol proposal: Based on these observations, a prospective randomized controlled trial is planned to compare ultrasound-guided acupotomy plus conventional therapy versus conventional therapy alone. Outcomes will be assessed quantitatively using gait analysis. Lessons and implications: Ultrasound-guided acupotomy may offer a minimally invasive, targeted approach to releasing spastic muscles while preserving neurovascular structures, thereby improving gait function in patients with post-stroke EVF.
