Variability of the Penn upper motor neuron score in amyotrophic lateral sclerosis: need for a revised score.
Article in Journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
There is a need for a consensus on a clinical scale for evaluating upper motor neuron (UMN) burden in amyotrophic lateral sclerosis (ALS) to improve consistency in clinical diagnosis, research and monitoring of disease progression. The Penn upper motor neuron score (PUMNS) is the most commonly published scale, however, the reliability of the scale has only been evaluated in a single study involving two raters. The objective of this study was to evaluate the inter-rater reliability of the PUMNS in ALS patients among multiple raters, and to discuss an updated UMN score including the signs with the highest inter-rater reliability. This study included seven ALS patients (mean age: 71 ± 11.5, six males, one female). Each patient was evaluated with the PUMNS by eight raters from different centers blinded to previous observations. The intra-class correlation coefficient (ICC) was calculated to assess the inter-rater reliability of the total PUMNS. The inter-rater reliability of the binary subscores was assessed with Gwet's AC1 coefficient. The inter-rater agreement for the total PUMNS yielded an ICC of 0.81 (95% CI 0.56;0.96). Items with the highest inter-rater reliability included Hoffman's sign, Babinski's sign, clonus and deep tendon reflexes, while the facial reflex (Gwet's AC1 -0.038 (95% CI -0.25,0.18)) and crossed adduction (0.18 (95% CI (-0.32,0.67)) had the lowest inter-rater reliability. In conclusion, PUMNS demonstrated good inter-rater reliability overall, while some of the subscores had poor inter-rater reliability. Based on this, we call for an updated UMN score to enhance diagnostic accuracy and research consistency in ALS.
