Comparison of KAFO and AFO for extension thrust pattern after stroke: a randomized N-of-1 trial.
Article in Journal of physical therapy science, 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
[Purpose] Extension thrust pattern (ETP) during the stance phase is a common gait deviation after stroke; however, there is no consensus regarding the optimal orthosis, such as knee-ankle-foot orthosis (KAFO) or ankle-foot orthosis (AFO). This study aimed to compare the effects of KAFO and AFO on ETP using an N-of-1 trial design. [Participant and Methods] A 54-year-old male with right thalamic hemorrhage and post-stroke hemiplegia participated in this study. A prospective multiple-crossover N-of-1 trial was conducted. Five intervention periods (3 consecutive days each) of KAFO and AFO use were randomly assigned, with a 1-day washout period between interventions. Hip, knee, and ankle joint angles during mid-stance, 10-m walking time, and step count were measured. [Results] KAFO use significantly reduced ankle plantar flexion compared with AFO. A particularly large effect size was observed for the ankle dorsiflexion angle. Improvements in walking time and step count were also noted with KAFO. [Conclusion] KAFO was more effective than AFO in improving ETP in this patient. Objective evaluation using an N-of-1 trial may support more appropriate orthotic selection in clinical practice.
