A bilateral upper limb interactive game-based virtual reality rehabilitation system for stroke patients: a usability and clinical study.
Trial report in Journal of neuroengineering and rehabilitation, 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
backgroundVirtual reality has received significant attention in clinical rehabilitation. Therefore, we developed a bilateral upper limb interactive game-based VR system for post-stroke rehabilitation of the upper extremities, and assessed its usability and clinical efficacy.
methodsWe carried out a usability test for this system within representative user groups. Then, the clinical efficacy was assessed through a randomized controlled trial, in which 22 patients with stroke received 12 sessions (4 weeks) of conventional physical therapy or bilateral upper limb synchronous training based on VR system in the clinic. The Wolf Motor Function Test-Functional Assessment Scale (WMFT-FAS), Fugl-Meyer Assessment for the Upper Extremity (FMA-UE), range of motion (ROM) of shoulder flexion, shoulder abduction, and elbow flexion, as well as bilateral temporal difference were recorded.
resultsThe requirements for stroke rehabilitation were established and incorporated into this VR system. The usability test revealed high ratings for interest, perceived competence, value, and effort, contrasted by low levels of perceived stress. The clinical trial demonstrated that VR-based bilateral training yielded superior efficacy compared to conventional physical therapy, as evidenced by greater improvements in WMFT-FAS (P = 0.007; ηp2 = 0.310), FMA-UE (P = 0.040; ηp2 = 0.195), shoulder flexion ROM (P = 0.025; ηp2 = 0.228), shoulder abduction ROM (P = 0.007; ηp2 = 0.314), elbow flexion ROM (P = 0.019; ηp2 = 0.245), and bilateral temporal difference (P < 0.001; ηp2 = 0.475).
conclusionsThe system is proven safe and effective for enhancing the function of the paretic upper limb and bilateral coordination in stroke patients.
