Functional and biomechanical effects of a self-locking ankle orthosis versus rigid taping: an observational crossover study.
Article in BMC sports science, medicine & rehabilitation, 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
objectiveTo compare the acute biomechanical and functional effects of rigid taping, the self-locking ankle orthosis (SLAO), and a free condition during two functional jump tests.
methodsForty-five physically active participants completed three randomized conditions (Free, Taping, SLAO) in a single-session crossover design. Functional performance was assessed using the Drop Jump Test and Side Hop Test, while ankle mobility was measured with the Weight-Bearing Lunge Test. Kinematic variables were obtained from 2D video analysis, and temporal parameters (contact time, flight time, jump height, RSI, and power) were recorded using the OptoJump system.
resultsCompared with the free condition, both taping and the SLAO significantly reduced ankle dorsiflexion in the Weight-Bearing Lunge Test (p = 0.001) and during landing in the Drop Jump Test (p = 0.001), with greater restriction under taping. In the Drop Jump Test, contact time and maximal knee flexion differed across conditions, but only ankle dorsiflexion at landing showed significant pairwise differences between all conditions (all p < 0.001). In the Side Hop Test, both fixation systems significantly altered all performance-related variables compared with the free condition (all p < 0.001), while no differences were observed between taping and orthosis.
conclusionsThe SLAO and ankle taping reduced functional performance compared with the free condition in the Drop Jump and Side Hop tests. Rigid taping induced greater restriction of ankle dorsiflexion, also evident in the Weight-Bearing Lunge Test, whereas the SLAO showed slightly greater sagittal mobility.
