Functional Recovery in Refractory Lower-Limb Complex Regional Pain Syndrome Following KAFO-Assisted Rehabilitation: A Longitudinal Case Report.
Article in Clinical case reports, 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
To describe the longitudinal functional recovery of a patient with refractory lower-limb complex regional pain syndrome (CRPS), a disabling condition associated with pain and motor dysfunction, following individualized KAFO-assisted rehabilitation, and to explore potential mechanisms underlying the observed recovery. Longitudinal case study with retrospective and prospective data collection from 2017 onward, including clinical assessment and validated outcome measures: Numeric Rating Scale, SF-36v2, and Barthel Index. A 62-year-old woman with refractory lower-limb CRPS, multimorbidity, osteoporosis, and multiple fragility fractures developed progressive functional decline and wheelchair dependence despite pharmacological therapy, sympathectomy, and spinal cord stimulation. An individualized rehabilitation program incorporating a carbon-fiber knee-ankle-foot orthosis (KAFO) was introduced. This was associated with marked pain reduction, improved independence, regained assisted ambulation, and sustained functional improvement over time. The observed recovery may reflect not only biomechanical stabilization and safer weight-bearing, but also improved sensory input, body representation, and sensorimotor integration. This case supports a function-oriented approach to advanced CRPS and suggests that orthosis-assisted rehabilitation may contribute to functional and neurophysiological recovery in selected complex patients.
