Case series shows feasibility and muscle activation improvements in prefrail older adults, indicating potential benefits of swallow training.
Key Points
Home-based swallow training program improved submental muscle activity and tongue strength in prefrail adults, highlighting its feasibility.
Results showed that two participants increased tongue strength beyond detectable thresholds, indicating meaningful neuromuscular gains.
Assessment involved using a wearable biofeedback device to monitor muscle activation during effortful swallowing tasks at home.
While training was well-tolerated, functional improvements in swallowing were limited, suggesting the need for further research to optimize the training.
