Biomechanical analysis of patients with mild Parkinson's disease during indoor cycling training.
Article in Journal of neuroengineering and rehabilitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundParkinson's disease (PD) is characterized by significant postural instability and gait impairments, yet many individuals with PD can continue cycling even with severe gait dysfunction. While previous research has investigated the preservation of pedaling ability, how individuals with PD regulate and adapt their balance control strategies during cycling remains largely unexplored. This study aims to identify the biomechanical adaptations in cycling balance control employed by individuals with PD and how they differ from those of healthy individuals.
methodsA total of 39 PD patients and 42 age-matched healthy controls participated in a cycling task using a steerable indoor cycling system that enables sliding and tilting motions, requiring them to actively maintain balance while following a straight-line trajectory. Cycling dynamics were analyzed using a sensor-equipped system designed to capture medio-lateral balance adjustments, including force exertion on the handlebars and saddle, lateral deviations, and pedaling speed.
resultsPD patients exhibited a higher coordination of upper and lower body in the medio-lateral direction (PD: 0.47 ± 0.18 vs. Control: 0.11 ± 0.30, p < 0.001), suggesting a stronger reliance on a leaning strategy for balance control. While PD patients cycled at a significantly lower freely chosen speed (6.49 ± 1.45 km/h vs. 10.28 ± 3.00 km/h, p < 0.001), their bike deviation was lower than that of healthy controls (PD: 17.1 ± 9.9 mm vs. Control: 22.8 ± 11.7 mm, p = 0.019), indicating a more constrained and controlled cycling pattern. Additionally, force distribution patterns and bike speed showed strong correlations with physical function measures, including lower limb strength and gait velocity.
conclusionsThis study identifies distinct cycling balance adaptations in PD, providing insights into how individuals with PD regulate and modify their balance control strategies during cycling. The quantitative metrics derived from this study may offer a basis for future research exploring their potential as biomechanical markers for objective functional assessment and rehabilitation monitoring in PD.
