Swallow Strength and Skill Training with biofeedback In acute Post stroke dysphagia (ssSIP): a protocol for a multi-centre feasibility trial.
Article in Pilot and feasibility studies, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
backgroundPost stroke dysphagia is common and has negative consequences on health and wellbeing. Collectively, behavioural interventions including swallow strength and skill training with biofeedback improve dysphagia, but little is known about which interventions are most effective and at what dose. Early intensive intervention may be most beneficial for motor recovery, but it is unclear whether dysphagia therapy such as this is feasible to deliver in the inpatient acute stage.
aimTo understand the feasibility of clinical teams delivering swallow strength and skill training with biofeedback in acute inpatient stroke and explore which dose may result in better outcomes.
methodsOne hundred twenty participants from inpatient stroke units 1-8 weeks post stroke in the UK will be recruited in this multi-centre prospective randomised controlled feasibility trial. If eligible, they will be randomised 1:1:1 to either usual care, low-intensity therapy (once daily) or high-intensity therapy (twice daily) groups. In addition to usual care, treatment groups will receive 1 or 2 × 35-min daily sessions of swallow strength and skill training with surface electromyographic biofeedback over 2 weeks. The primary outcome is feasibility measured by recruitment and treatment fidelity. Secondary outcomes will explore treatment effects and dose of the intervention on swallowing, clinical, quality of life and health economic outcomes. Embedded qualitative process evaluation of intervention delivery (fidelity, barriers and enablers), clinical staff training and trial procedures informed by the Conceptual Framework for Intervention Fidelity (CFIF) and Conceptual Framework for Implementation Research (CFIR). Criteria have been outlined for progression to a definitive study. DISCUSSION: This trial will inform the feasibility of a definitive study to determine the effectiveness of optimal dose swallow strength and skill training with surface electromyographic biofeedback on the severity of dysphagia 3 months post stroke. The process evaluation will inform refinements to the intervention, training and trial procedures to ensure effective delivery.
