Enhancing wellness: a systematic review of biofeedback interventions for healthcare professionals.
Synthesis in Frontiers in psychiatry, 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/objectives: Healthcare professionals are routinely exposed to high psychosocial and physiological demands, placing them at elevated risk for stress-related disorders, including burnout, anxiety, and impaired autonomic regulation. Biofeedback has emerged as a promising non-pharmacological approach to enhance self-regulation and resilience. This systematic review aimed to evaluate the effectiveness of biofeedback-based interventions in improving psychological and physiological outcomes among healthcare workers. Methods: A systematic search was conducted across PubMed, Cochrane, Embase, PsycINFO, and grey literature (December 2023-January 2024), following PRISMA guidelines and a registered PROSPERO protocol (CRD42024544687). Eligible studies included randomized controlled trials, quasi-experimental designs, and pre-post studies involving adult healthcare workers exposed to work-related stress. Primary outcomes comprised stress, burnout, anxiety, depression, resilience, and physiological indices such as heart rate variability (HRV), respiratory rate, and skin conductance. Data were synthesized narratively due to methodological heterogeneity. Twelve studies met inclusion criteria. HRV-biofeedback and respiratory sinus arrhythmia training demonstrated. Results: consistent improvements in perceived stress, anxiety, depressive symptoms, emotional regulation, and resilience. Physiological benefits included increased HRV, decreased sympathetic arousal, and improved autonomic balance. Interventions integrating breathing or mindfulness techniques exhibited the strongest effects. However, non-randomized designs and small samples limited the robustness of findings. Discussion/Conclusions: Biofeedback represents a feasible and potentially effective strategy for mitigating occupational stress and enhancing psychophysiological well-being in healthcare professionals. Despite promising results, evidence remains preliminary due to heterogeneity, limited methodological rigor, and scarce long-term follow-up. Future large-scale randomized trials with standardized protocols are needed to strengthen the evidence base and support implementation in occupational health settings.
