Topic: Risk, prevention and care in population studies
This review included 24 studies involving 2979 participants (1717 with dysphagia and 1262 controls). In total, 75% (18/24) of the studies focused solely on per-individual classification rather than per-swallow event classification. Acoustic (13/24, 54%) and vibratory (9/24, 38%) signals were the primary modality sources. In total, 25% (6/24) of the studies used multimodal approaches, whereas 75% (18/24) used a single modality. Support vector machine was the most common AI model (15/24, 62%), with deep learning approaches emerging in recent years (3/24, 12%). Performance varied widely-accuracy ranged from 71.2% to 99%, area under the receiver operating characteristic curve ranged from 0.77 to 0.977, and sensitivity ranged from 63.6% to 100%. Multimodal systems generally outperformed unimodal systems. The methodological quality assessment revealed a risk of bias, particularly in patient selection (unclear in 18/24, 75% of the studies), index test (unclear in 23/24, 96% of the studies), and modeling (high risk in 13/24, 54% of the studies). Notably, no studies conducted external validation or domain adaptation testing, raising concerns about real-world applicability. This review provides a comprehensive overview of technological advancements in AI and sensor-based dysphagia screening. While these developments show promise for continuous long-term tele-swallowing assessments, significant methodological limitations were identified. Future studies can explore how each modality can target specific anatomical regions and manifestations of dysphagia. This detailed understanding of how different modalities address various aspects of dysphagia can significantly benefit multimodal systems, enabling them to better handle the multifaceted nature of dysphagia conditions.

Key findings
- This review included 24 studies involving 2979 participants (1717 with dysphagia and 1262 controls).
- In total, 75% (18/24) of the studies focused solely on per-individual classification rather than per-swallow event classification.
- Acoustic (13/24, 54%) and vibratory (9/24, 38%) signals were the primary modality sources.
- In total, 25% (6/24) of the studies used multimodal approaches, whereas 75% (18/24) used a single modality.
- Support vector machine was the most common AI model (15/24, 62%), with deep learning approaches emerging in recent years (3/24, 12%).
Why it matters
This review of 24 studies found that AI and sensor-based dysphagia screening shows promise for continuous long-term tele-swallowing assessments, but no studies conducted external validation or domain adaptation testing. The evidence is limited by risk of bias in patient selection, index test, and modeling, so real-world applicability remains uncertain.
