Digital Physiotherapeutic Elbow-Specific Training System for Patients After Arthroscopic Release of Elbow Contracture: Noninferiority Randomized Controlled Trial.
Trial report in JMIR mHealth and uHealth, 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
backgroundThe effectiveness of a digital training (DT) system in which patients receive individually tailored physiotherapeutic elbow-specific training (PEST) delivered via a digital platform remains unclear.
objectiveThis study determines the effectiveness of a DT system in which patients receive individually tailored PEST supervision and guidance via the Joymotion Intelligent Rehabilitation System and educational videos, compared with conventional training (CT) conducted by qualified physiotherapists at outpatient clinics and unsupervised home-based PEST in patients following arthroscopic release for posttraumatic elbow stiffness.
methodsThis single-center, noninferiority randomized controlled trial was conducted at the Rehabilitation Department of Shanghai Sixth People's Hospital between September 2020 and June 2024. Patients aged 16-65 years undergoing arthroscopic release for posttraumatic elbow stiffness were randomized to receive either a 12-week DT program or conventional outpatient clinic-based training. Outcome measures included elbow flexion-extension range of motion (primary outcome); forearm rotation; isometric and dynamic muscle strength; American Shoulder and Elbow Surgeons (ASES) and Disabilities of the Arm, Shoulder, and Hand (DASH) scores; EQ-5D-5L; cost-effectiveness; adherence; and adverse events, assessed at 4, 12, and 24 weeks postoperatively.
resultsAt 12 weeks, the mean elbow flexion-extension range of motion improved similarly in the DT and CT groups (between-group difference -1.6°, 95% CI -8.2° to 4.9°; P=.53), confirming noninferiority. Forearm rotation gains were slightly greater with DT (difference 14.2°, 95% CI 2.9°-25.6°). Patient-reported outcomes were equivalent between groups: ASES function (difference 0.6, 95% CI -0.3 to 1.5; P=.39) and pain (difference 0, 95% CI -8.3 to 8.5; P=.68) subscores, DASH (difference 0.23, 95% CI -1.54 to 1.99; P=.68), and EQ-5D-5L index (difference 0.001, 95% CI -0.012 to 0.015; P=.56) showed no significant between-group differences. Nearly all patients completed the 12-week program in both arms (104/106, 98.1%, vs 101/102, 99%, adherence; odds ratio 0.52, 95% CI 0.05-5.77). Adverse events occurred in 29 out of 106 (27.4%) participants in the DT group and 32 out of 102 (31.4%) participants in the CT group (odds ratio 0.82, 95% CI 0.45-1.50). Total rehabilitation costs per patient were lower in the DT group by an average of CNY -7418.58, and incremental cost-effectiveness analysis indicated that DT provided comparable outcomes at lower cost.
conclusionsIndividually tailored PEST delivered via a DT system is a viable, cost-effective, and safe alternative to conventional outpatient clinic-based training following arthroscopic release for posttraumatic elbow stiffness. These findings support its integration into routine postsurgical care, particularly for patients facing barriers to traditional therapy.
