Tiivistelmä
Immediate effects of 'Voice Massage' treatment on hyperfunctional dysphonia
`Voice Massage' (VM) treatment manipulates muscles related to voice and speech production. This study used objective acoustic and aerodynamic and subjective questionnaire measurements to investigate the instant effects of VM in 10 female patients diagnosed with hyperfunctional dysphonia. They recorded repetitions of word `paappa' as softly as possible and in habitual loudness and read a text sample before and after 1-hour VM-treatment and 1-hour lying on bed. Subglottic pressure was estimated from oral pressure during [p] in the syllable repetitions. Transglottal flow was captured with a mask. Glottal resistance (pressure / flow) was calculated. Voice production was studied with electroglottography (EGG), from which the closed quotient (CQ, i.e. closed time/ total period) was calculated. Fundamental frequency and sound pressure level (SPL) were measured from both syllable repetitions and the text samples and alpha ratio [(SPL of the range 1-5 kHz) - (SPL of the range 50 Hz-1 kHz)] was calculated from the text samples. A questionnaire was used to record subjective sensations. F0 and SPL were lower both after VM and resting, but the changes did not differ significantly between these conditions. No significant changes were found in resistance or in CQ. Subjects reported significantly more increase in the ease of phonation and reduction of tension in the neck, shoulders and back after VM compared to resting. The positive subjective effects of VM may reflect pure psychological reactions or possibly some positive physiological changes that cannot be measured in the vocal parameters used.
Key words: Massage, subjective sensations, glottal resistance, EGG, F0, SPL, spectrum slope
