Optimizing the dynamic treatment regime of outpatient rehabilitation in patients with knee osteoarthritis using reinforcement learning.
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 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
backgroundKnee osteoarthritis (KOA) is a prevalent chronic disease worldwide, and traditional treatment methods lack personalized adjustment for individual patient differences and cannot meet the needs of personalized treatment.
methodsIn this study, a dedicated knee osteoarthritis bank (KOADB) was constructed by collecting extensive clinical data from patients. Random forest was used to select the features that had the greatest impact on treatment decisions from 122 questionnaire items. The questionnaire design was optimized to reduce the burden on patients and ensure the validity of data collection. Then, based on the key features screened out, a dynamic treatment recommendation system was constructed by using deep reinforcement learning algorithms, including Deep Deterministic Policy Gradien(DDPG), Deep Q-Network(DQN) and Batch-Constrained Q-learning(BCQ). A large number of simulation experiments have verified the effectiveness of these algorithms in optimizing the treatment strategy of KOA. Finally, the applicability and accuracy of the model were evaluated by comparing the treatment behaviors with actual patients.
resultsIn the application of deep reinforcement learning algorithms to treatment optimization, the BCQ algorithm achieves the highest success rate (79.1%), outperforming both DQN (68.1%) and DDPG (76.2%). These algorithms significantly outperform the treatment strategies that patients actually receive, demonstrating their advantages in dealing with dynamic and complex decisions.
conclusionsIn this study, a deep learning-based KOA treatment optimization model was developed, which was able to adjust the treatment plan in real time and respond to changes in patient status. By integrating feature selection and reinforcement learning techniques, this study proposes an innovative method for treatment optimization, which offers new possibilities for chronic disease management and demonstrates certain feasibility in the development of personalized medicine and precision treatment strategies.
