Mirror therapy for postoperative functional recovery after surgical repair of upper-limb traumatic peripheral nerve injuries: a systematic review and meta-analysis.

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: Traumatic peripheral nerve injuries of the upper limb often lead to substantial motor and sensory deficits, posing significant challenges to functional recovery and quality of life. Mirror therapy, a visually guided neurorehabilitation technique, has shown potential in enhancing upper limb function, yet its effectiveness in traumatic peripheral nerve injuries remains inconclusive. Methods: This systematic review and meta-analysis followed PRISMA 2020 guidelines. Randomized controlled trials involving adult patients with upper limb traumatic peripheral nerve injuries treated with mirror therapy were identified through searches of seven major databases up to Augst 2025. Methodological quality was assessed using the PEDro scale, and pooled analyses were performed using standard mean differences with 95% confidence intervals. Results: Seven clinical studies involving 112 participants were included and five randomized controlled trials contributed to the meta-analysis. Mirror therapy significantly improved hand function measured by the Rosen Score (SMD = 0.24; 95% CI: 0.02 to 0.46; Conclusion: Mirror therapy may offer modest benefits in hand function recovery following upper limb traumatic peripheral nerve injury. However, current evidence is limited by small sample sizes, methodological heterogeneity, and low study quality. No significant effects were observed for sensory or pain-related outcomes. Further high-quality randomized controlled trials with standardized protocols and long-term follow-up are needed to establish the clinical efficacy and optimize the use of mirror therapy in this population.
