Abstract
|
|
|
Objectives : The aim of this study is to find the acoustic characteristics of acupuncture therapy effects on post-stroke dysarthria.
Methods : Acupuncture therapy was applied for four to six weeks by inserting needles into eight acupuncture points, CV23, CV24, bilateral ’Sheyu’ and ipsilateral ST4, ST6 and contralateral LI4, ST36 on facial palsy side. All the speech samples were collected, pre-treatment and post-treatment, using Computerized Speech Lab. VOT and TD of each speech sample and vowel formant(F1&F2) were analyzed on spectrogram.
Result : VOT and TD were decreased after treatment. F1 was decreased, and F2 was increased after treatment.
Conclusions : This suggests that acupuncture therapy improves symptoms of post-stroke dysarthria by stimulating articulation organs such as tongue, lips, cheeks, larynx and pharynx.
