Purpose: Physiological ageing affects function of the evolved human larynx with respect to both speech communication and swallowing. Those decrease the quality of life in human being. For the latter, it increases the tendency for aspiration. This will increasingly become a problem as lifespan increases and a growing number of people suffer from physiological ageing. Here I suggest a simple solution for such ageing problems.
Methods: Based on my previous research (National Hospital Organization Japan program, Randomized control trial) and clinical experiment.
Results: As a substitute for laryngeal elevation, we recommend that people draw in the jaw during the act of swallowing. A vocal exercise therapy allowed vocal cords to adduct and improved glottal closure insufficiency.
Conclusion: “Just keep communicate to speak in old age”, which prevent the vocal fold and the intrinsic laryngeal muscles atrophy for the volume and adduction of vocal folds movement for the satisfactory glottal closure.
