Abstract: ObjectiveTo explore the characteristics and rehabilitation of dysarthria patients who speak mandarin. Methods18 patients were rehabilitated with physiologic approach for 40 d. Before and after rehabilitation, maximum phonation time (MPT), frequency, tone and expiratory rate were tested with phonolaryngeal graph, while forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), maximum midexpiratory flow (MMF), peak expiratory flow rate (PEFR) were tested with Microspiro; Articulation and intelligibility were tested with mandarin words table and rate of sentence and paragraph. ResultsCompared with that before intervention, MPT of the patients were longer after intervention (P<0.05). The FVC was lower than normal rate before intervention and it was remarkable higher after intervention(P<0.01).Correct rate of sentence and paragraph was remarkable higher(P<0.01). ConclusionTests of Phono-laryngograph, Microspiro and correct rate of sentence are good comprehensive evaluation methods to speech and phonation of dysarthria. Physiologic approach to rehabilitation can remarkably improve patient's communication ability.
