🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the
last 12 months.
|
Disability and rehabilitation (2025) - Network Meta-Analysis
Key Findings
- The Masako maneuver produced the largest improvement in dysphagia severity, with SMD 1.57 (95% CI 1.16-1.98).
- Expiratory muscle strength training reduced aspiration risk (SMD 0.71, 95% CI 0.35-1.06), while tongue resistance exercise improved anterior and posterior tongue strength by MD 4.24 and 4.45.
📋 Practice Implication: Match the rehabilitation exercise to the dominant impairment, using Masako for severity reduction, EMST when aspiration risk is prominent, and tongue resistance work when lingual weakness is limiting bolus control.

Clinical otolaryngology : official journal of ENT-UK ; official journal of Netherlands Society for Oto-Rhino-Laryngology & Cervico-Facial Surgery (2025) - Meta-Analysis
Key Findings
- Respiratory training improved forced expiratory volume in 1 second and peak expiratory flow versus control, with both outcomes reaching p < 0.001 in pooled analysis.
- Penetration-Aspiration Scale scores improved by MD -2.16 (95% CI -2.35 to -1.98), indicating lower aspiration risk than conventional care.
📋 Practice Implication: Add respiratory muscle training when older adults with dysphagia also have weak cough or poor pulmonary reserve, because the benefit appears to extend beyond swallowing mechanics to airway protection.

Gerodontology (2025) - RCT
Key Findings
- High-intensity tongue strengthening at 80% 1RM increased tongue strength from 16.7 to 22.1 kPa and thickness from 37.1 to 40.5 mm, outperforming 50% 1RM training.
- The higher-intensity program produced greater post-intervention gains than low intensity for both strength (+3.0 kPa, d = 1.46) and thickness (+1.7 mm, d = 0.56), but dropout was higher at 26.7% versus 6.7%.
📋 Practice Implication: Use higher-intensity tongue training for sarcopenic dysphagia when the patient can tolerate it, but monitor adherence closely and step down intensity if the burden threatens completion.

Journal of oral rehabilitation (2025) - RCT
Key Findings
- Combined tongue resistance plus strengthening improved anterior tongue strength, posterior endurance, saliva swallowing pressure, effortful swallow pressure, and repetitive saliva swallowing versus control, with beta estimates ranging from 4.0 to 12.1.
- Swallowing quality of life improved by beta 29.3 (95% CI 22.4-36.2), and gains in repetitive saliva swallowing and SWAL-QOL were sustained at 12-week follow-up with booster training.
📋 Practice Implication: Do not exclude frail older adults with mild cognitive impairment from active rehabilitation; a combined tongue program with booster sessions can still deliver durable functional benefit.
|
Journal of oral rehabilitation (2025) - RCT
Key Findings
- The active neck-collar device produced greater improvements in suprahyoid muscle activation and thickness than the sham device, with all between-group comparisons reaching p < 0.05.
- Penetration-Aspiration Scale scores were significantly lower with the active device than placebo, indicating reduced airway penetration and aspiration risk.
📋 Practice Implication: Consider device-assisted suprahyoid strengthening for older adults with oral hypofunction when reduced hyolaryngeal excursion or persistent penetration-aspiration remains a central treatment target.

Summary
Recent evidence in older adults with dysphagia supports targeted exercise-based rehabilitation rather than a single generic program. Network and conventional meta-analyses found that different interventions improve distinct outcomes, with respiratory training lowering aspiration-related measures and tongue or suprahyoid strengthening improving swallowing physiology; newer RCTs suggest these gains extend to frail adults and those with mild cognitive impairment when training intensity and adherence are managed carefully.
