Test-Retest and Inter-Rater Reliability of the 20-Meter Ambulation Test in Patients with Parkinson's Disease.
Article in Journal of rehabilitation medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveIn patients with Parkinson's disease, limited sit-to-stand, walk and turn contribute to decreased independence and quality of life. The 20-meter Ambulation Test (AT20) evaluates walking a total of 20 m, over a 10-m distance, back and forth between 2 chairs, starting and ending in a seated position. The aim of this study was to evaluate test-retest and inter-rater reliability of the AT20 in patients with Parkinson's disease.
methodsPatients with idiopathic Parkinson's disease performed the AT20 in 3 conditions: free speed, fast speed, and with large steps, twice 1 week apart. The total number of steps and the time to complete the task were recorded manually by 4 independent raters. The main outcome criteria were the test-retest and inter-rater intraclass correlation coefficients and coefficients of variation for speed, step length and cadence in the 3 conditions.
resultsTwenty participants completed the 2 visits. Across all conditions, test-retest and inter-rater intraclass correlation coefficients for step length and speed were > 95%. Test-retest and inter-rater coefficients of variation were < 0.08.
conclusionThe AT20 is a reliable ambulation test in Parkinson's disease, with excellent test-retest and inter-rater reliability for step length and speed in all 3 conditions: at free speed, fast speed, and with large steps. The AT20 might be useful to assess ambulation in parkinsonism in clinical practice.
