OBJECTIVES Water resistance therapy by phonating through a tube into the water is used to treat dysphonia. Deep submersion (≥10 cm in water, "deep bubbling") is used for hypofunctional voice disorders. Using it with caution is recommended to avoid vocal overloading. This experimental study aimed to investigate how strenuous "deep bubbling" is. STUDY(More)
OBJECTIVE This study compares the flow resistance of Resonance tube (RT) and Lax Vox tube (LVT) when submerged 2 cm and 10 cm in water, as well as phonation into the tubes in these conditions. METHODS In the in vitro experiment, the air pressure for flow rates of 60-600 mL/s was measured at the tube inlet, when the outer end of the tube was submerged 2 cm(More)
'Voice massage' (VM) treatment includes manipulation of muscles related to speech production and voice and breathing exercises. This study investigated the effects of VM in 10 healthy subjects (5 females, 5 males). They recorded repetitions of the word 'paappa' at normal loudness and as softly as possible and read a text sample before and after 1-hour (1)(More)
OBJECTIVES The study aims to investigate the vocal fatigue symptoms and laryngeal status in relation to vocal activity limitations and vocal participation restrictions.
