Relation of pain sensitization to knee loading during walking in people with knee osteoarthritis.
Article in Osteoarthritis and cartilage, 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
objectiveTo examine the association of pain sensitization with knee joint loading during walking in people with knee osteoarthritis (OA).
methodFor this cross-sectional study, we used baseline data from participants with symptomatic knee OA (n=104) enrolled in two clinical trials. We used pressure pain threshold (PPT) at the knee and wrist to assess sensitization. Using gait analyses during walking, we derived peaks and impulse of knee adduction moment (KAM) and knee flexion moment, and frontal and sagittal plane range of motion during stance. We used an Analysis of Covariance (ANCOVA) adjusted for age, sex, body height, and body weight to examine associations of PPT (sex-specific tertiles) with gait outcomes. Sensitivity analyses included additional adjustment for gait speed.
resultsFor knee PPT, the lowest tertile had a lower 1st peak of KAM (∆=9.1 Nm [95% CI; 0.3, 17.9]) compared to the highest tertile. For wrist PPT, when compared to the highest tertile, the lowest tertile had a lower 1st peak of KAM (∆=9.1 Nm [1.3, 16.8]), a lower 2nd peak of KAM (∆=7.5 Nm [0.5, 14.6]), and a lower KAM impulse (∆=1.7 Nm*s [0.1, 3.2]), while the middle tertile also had a lower 2nd peak of KAM (∆=8.0 Nm [0.7, 15.4]) and a lower KAM impulse (∆=2.0 Nm*s [0.4, 3.6]). The effect sizes for other gait measures were small and clinically not meaningful. These effect sizes remained similar after adjusting for gait speed.
conclusionGreater pain sensitivity, as assessed by PPT, was related to lower frontal plane joint loading during walking. These findings may reflect a motor adaptation to nociceptive alterations in this population.
