Which spatiotemporal parameters are predicted by commonly used osteoarthritis questionnaires in clinical practice? An exploratory study.
Article in BMC musculoskeletal disorders, 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
backgroundKnee osteoarthritis (KOA) leads to altered gait patterns, yet the relationship between objective spatiotemporal gait parameters and subjective clinical assessment tools remains unclear. This study aimed to examined the relationship between spatiotemporal gait parameters and commonly utilized KOA assessment questionnaires in clinical practice.
methodsA prospective, cross-sectional study was conducted with 30 patients diagnosed with Kellgren-Lawrence Grade 3 bilateral KOA, randomly selected from a university hospital outpatient clinic. Demographic data, including age and body mass index, were recorded. Spatiotemporal gait parameters were assessed using instrumented gait analysis. Disease severity was evaluated using validated self-reported questionnaires: the Lequesne Index, Oxford Knee Score, Pain Catastrophizing Scale (PCS), and WOMAC subscales (Pain, Joint Stiffness, Function, and Total Score). Correlation and regression analyses were performed to identify associations between gait parameters and osteoarthritis severity scores.
resultsSignificant correlations were found between gait parameters and osteoarthritis scales. Total double support duration was positively associated with the Lequesne (r = 0.511, p = 0.009), Oxford (r=-0.455, p = 0.022), and WOMAC (r = 0.448, p = 0.025), indicating a link between prolonged double support time and disease severity. Step length was negatively correlated with PCS (r=-0.477, p = 0.016), suggesting that greater pain catastrophizing was associated with reduced step length. Regression analysis revealed that total double support time was the strongest predictor of the Lequesne (36.4%), Oxford (43.6%), and WOMAC (36.4%), highlighting its clinical significance.
conclusionSpatiotemporal gait parameters, particularly total double support time and step length, are closely associated with patient-reported KOA symptom severity. These parameters may serve as objective clinical indicators for monitoring disease progression and informing rehabilitation strategies.
