Efficacy of blood flow restriction training in chronic ankle conditions: a systematic review and meta-analysis.
Synthesis in BMC musculoskeletal disorders, 2026. 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
backgroundChronic ankle conditions often lead to persistent functional limitations. Blood flow restriction (BFR) training is a potential adjunct to rehabilitation, but its specific efficacy for chronic ankle conditions remains to be synthesized.
objectiveTo systematically evaluate the effects of BFR-assisted rehabilitation on primary outcomes (dynamic balance and patient-reported ankle stability) and secondary outcomes (ankle range of motion and muscle strength) in individuals with chronic ankle conditions (including chronic ankle instability, chronic ligamentous injury, and tendinopathy).
methodsA systematic search of PubMed, Web of Science, Embase, CNKI, and Wanfang databases was conducted up to April 13, 2025. We included randomized controlled trials (RCTs) involving adults with chronic ankle instability (CAI) defined by a history of sprain and/or Cumberland Ankle Instability Tool (CAIT) score < 24. Grey literature was excluded. The protocol was registered on PROSPERO (CRD420251249207). Methodological quality was assessed using the Cochrane Risk of Bias (RoB) 1.0 tool. Data were pooled using random- or fixed-effects models.
resultsSeven RCTs (n = 204) were included. The overall risk of bias across the included studies was generally low to moderate. Meta-analysis of post-intervention values indicated that BFR-assisted rehabilitation significantly improved the primary outcome of dynamic balance (MD = 5.75; 95% CI [2.10, 9.40]; P < 0.01; I
conclusionsBFR-assisted rehabilitation appears to enhance dynamic balance and perceived ankle stability in patients with chronic ankle conditions. However, evidence regarding its effect on joint range of motion remains inconclusive because of data instability. Current evidence supports BFR as a functional intervention, though standardized protocols are needed to further validate its clinical utility.
