Establishing levels of arm-hand activities in stroke patients: the arm-hand-activities-scale (AHAS).
Article in Journal of rehabilitation medicine, 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
objectivePost-stroke limitations in arm-hand activities are prevalent, yet a system for categorizing these limitations like the Functional Ambulation Categories (FAC) is lacking. The Arm-Hand-Activities-Scale (AHAS) was developed and psychometric properties of this classification were investigated.
designMixed methods to examine comprehensibility, inter-rater reliability, correlations with the Fugl-Meyer Assessment (FMA) and the Action Research Arm Test (ARAT), and sensitivity to change. SUBJECTS/PATIENTS: 76 professionals answered a comprehensibility questionnaire and 85 professionals an inter-rater reliability questionnaire.
methodsFor comprehensibility and inter-rater reliability, standardized video sequences of each category were assessed. Cut-off values were identified by comparing the AHAS categories with the FMA (n = 10) and the ARAT (n = 71). For sensitivity-to-change studies, 71 stroke patients were followed for 4 weeks of inpatient rehabilitation. Spearman correlation coefficients were calculated to examine the relationship between AHAS, FMA, and ARAT outcomes. A Wilcoxon signed-rank test was applied for sensitivity to change.
resultsThe results on comprehensibility of the AHAS categories and the FMA cutoff values were highly consistent. Inter-rater reliability was good to excellent. A significant and strong correlation was found between ARAT and AHAS. The Wilcoxon signed-rank test for sensitivity to change was also significant.
conclusionThe AHAS provides a quick and simple classification system to assess the severity of arm-hand activity limitations after stroke This may help in selecting appropriate treatment strategies.
