Quantifiable ankle pump exercise monitoring for early postoperative rehabilitation after hip and knee arthroplasty: an exploratory randomized controlled trial.
Trial report in Frontiers in rehabilitation sciences, 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: Deep vein thrombosis (DVT) remains a clinically important complication after hip and knee arthroplasty. Although ankle pump exercise (APE) is widely recommended to promote venous return, adherence is often suboptimal. Quantifiable monitoring may improve exercise delivery, but its clinical value remains uncertain. Objective: To evaluate quantifiable APE monitoring for postoperative exercise adherence, DVT incidence, venous hemodynamics, and rehabilitation-related outcomes after hip or knee arthroplasty. Methods: This prospective, single-center, open-label exploratory randomized controlled trial enrolled 100 patients undergoing hip or knee arthroplasty between July and November 2023. Patients were randomized 1:1 to an experimental group receiving wearable sensor-based APE monitoring with a mobile application and real-time data transmission or a control group receiving conventional APE education and routine reminders. The registered co-primary outcomes were exercise adherence on postoperative day 7 and DVT incidence by postoperative day 14. Secondary outcomes included venous hemodynamic parameters and patient-reported outcomes, including self-efficacy assessed using the General Self-Efficacy Scale (GSES), perceived exertion assessed using the Rating of Perceived Exertion (RPE), pain assessed using the Visual Analog Scale (VAS), and patient satisfaction. Results: Exercise adherence (86% vs. 64%; absolute difference, 22.0 percentage points; 95% CI, 5.6 to 38.4; Conclusions: Quantifiable APE monitoring was associated with improved exercise adherence and favorable short-term rehabilitation-related and venous hemodynamic outcomes. However, the study was not powered to determine whether the intervention prevents DVT. Clinical Trial Registration: https://www.chictr.org.cn/showproj.html?proj=200872, identifier, ChiCTR2300073531.
