Effectiveness of stationary cycling with electromyographic biofeedback on neuromuscular control and function in individuals with knee osteoarthritis: a feasibility study.
Trial report in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03484910 (Application of Biofeedback Combined With Cycling Exercise in the Patients With Osteoarthritis of the Knee), which is not on this 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.

Abstract
backgroundTo evaluate the effects of stationary cycling with electromyographic (EMG) biofeedback on neuromuscular control and function in individuals with knee osteoarthritis (OA).
methodsFourteen knee OA patients were randomized into two groups: cycling with EMG biofeedback of the vastus medialis (EBF group) and cycling without biofeedback (Cycling group). Both groups underwent a six-week cycling program, 30 min per session, twice a week. Outcomes were measured at baseline and post-training. Knee pain and function were assessed using the Visual Analog Scale and the Knee Injury and Osteoarthritis Outcome Score (KOOS). Quadriceps strength and endurance were evaluated with an isokinetic machine, and muscle activation was recorded using a wireless EMG system. A two-way mixed-model analysis of variance (ANOVA) was used to assess the differences between sides and groups. For outcomes that were not normally distributed, the non-parametric Mann-Whitney U test was performed.
resultsBoth groups showed improvements in knee pain and function, with no significant differences between groups. Muscle strength remained largely unchanged, but the endurance was improved on the contralateral side (p = 0.038, η
conclusionsA six-week cycling program can alleviate pain and enhance knee function. EMG biofeedback of the vastus medialis significantly changed the neuromuscular control in the rectus femoris and vastus lateralis during cycling. Therefore, this study demonstrated that stationary cycling combined with electromyographic biofeedback training can enhance neuromuscular control of the quadriceps and potentially improve functional performance in patients with OA.
