Efficacy of Tuina Therapy Based on Hip-Knee-Ankle Synergy in the Lower Extremity Kinematic Chain in Patients With Knee Osteoarthritis: Protocol for a Randomized Controlled Trial.
Article in JMIR research protocols, 2025. 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) is a progressive degeneration of the knee joint that has the potential to impair the function of the lower extremity. Tuina, as an important component of traditional Chinese medicine (TCM), is a common treatment for KOA. However, the prevailing practice often limits the therapeutic focus to the knee joint, overlooking potential coexisting hip and ankle injuries. Thus, the therapeutic efficacy may not be optimal in these instances.
objectiveThis study aims to evaluate the clinical efficacy of Tuina therapy based on hip-knee-ankle synergy combined with conventional treatment in patients with KOA. It also seeks to explore the potential effects on the lower extremity kinematic chain and provide clinical practitioners with a potentially valuable therapeutic approach.
methodsThis single-blind randomized controlled trial (RCT) will involve a total of 96 participants with KOA from 1 study center (including 2 branches). Participants will be randomly divided into a conventional treatment (control) group and a Tuina+conventional treatment (intervention) group in a 1:1 ratio. Participants in the control group will receive regular health education, self-administered acupressure, and functional exercise. This routine will be completed in 4 weeks, with a total of 5 sessions planned each week. Participants in the intervention group will receive 8 sessions of Tuina therapy based on hip-knee-ankle synergy (twice a week for 4 weeks), combined with conventional treatment. The primary outcome of this study will be improvement in WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) scores from baseline to 16 weeks. Among the secondary measures, the Key Symptoms and Signs/TCM Syndrome Classification Quantitative Evaluation of KOA and the 11-item Tampa Scale of Kinesiophobia (TSK-11) score will be evaluated from baseline to 16 weeks. The Functional Movement Screen (FMS), the Timed Up and Go (TUG) test, and the Weight Bearing Lunge Test (WBLT) scores will only be evaluated at baseline and 4 weeks.
resultsThe trial commenced in September 2024 and is expected to conclude in September 2025. As of April 2025, key preliminary steps have been successfully completed. Specifically, the ethical review and clinical trial registration have been finalized. Participant recruitment is proceeding well, with 69 individuals having been enrolled to date. Data collection is currently ongoing, and formal data analysis has not yet been initiated.
conclusionsThis RCT aims to contribute to the growing evidence base supporting the necessity of kinetic chain-based integrative diagnosis and treatment, while also evaluating the feasibility of the study protocol and exploring the benefits of manipulative therapy.
