Digital Therapeutics for Postoperative Rehabilitation after Arthroscopic Rotator Cuff Repair: A Single-Center, Assessor-Blinded, Randomized Pilot Study.
Trial report in Clinics in orthopedic surgery, 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
Background: Home-based rehabilitation after arthroscopic rotator cuff repair (ARCR) often lacks objective monitoring. To address this limitation, we developed the ANAPA digital rehabilitation (DR) system, which includes a patient-facing mobile application for clinical efficacy evaluation (ANAPA ME) and a physician-facing measurement application for technical assessment (ANAPA PS). This study compared the safety and preliminary efficacy of ANAPA ME with conventional YouTube-based rehabilitation (CR), with an additional validation of the automated measurement functions in ANAPA PS. Methods: This single-center, assessor-blinded, randomized pilot study included 18 patients who had undergone ARCR. The participants were allocated to the DR group (n = 9) or CR group (n = 9) and followed identical postoperative rotator cuff exercise protocols. The program was conducted for 24 weeks postoperatively. The shoulder range of motion (ROM), muscle strength, and clinical outcomes (visual analog scale pain score, Constant shoulder score, Shoulder Pain and Disability Index, and EuroQol-5 Dimension-5 Level questionnaire) were evaluated at baseline and at follow-up up to 24 weeks postoperatively. Ultrasonography was performed at 24 weeks to evaluate the integrity of the repaired tendons. Automated ROM and muscle strength measurements of ANAPA PS were validated against digital goniometry and hand-held dynamometry at the 6-month follow-up, and measurement consistency was assessed using intraclass correlation coefficients (ICCs) and coefficients of variation (CV). Results: Both the DR and CR groups demonstrated significant within-group improvements in ROM and clinical scores ( Conclusions: In this exploratory pilot study, the ANAPA DR system demonstrated favorable trends compared with CR in patients after ARCR, suggesting the feasibility and safety of artificial intelligence-based digital therapeutics in postoperative shoulder rehabilitation. The supplementary validation further demonstrated the technical reliability and measurement consistency of the ANAPA PS automated measurement functions for monitoring rehabilitation outcomes.
