AIMS & OBJECTIVE: To evaluate the efficacy of pushing strategy among the patients with unilateral vocal fold paralysis caused by different aetiologies by acoustic evaluation of voice analysis. MATERIALS AND METHODS Patient Selection: Twelve patients (7 male and 5 female) with unilateral cord palsy were included. The age range was from 17 to 63 years. The therapy session at least 30 minutes in a week after the onset of vocal cord paralysis and a multi-dimensional assessment was carried out before the therapy and immediately after the therapy. Those patients who did not meet the above criteria were omitted from the study. Instrument: Computerised Speech Lab (CSL), Model 4500 (Pentax Medical, Japan). The microphone was kept at a constant distance of 15 cm from the subjects’ mouths and they were asked to enunciate a sustained /‘a’/ at the maximum pitch level and repeated three times. RESULTS AND DISCUSSION: Subject’s pre therapy of pushing-pulling exercise and post therapy exercise of the subjects were objectively assessed and found that there is variation in the values of Maximum Phonation Duration and Fundamental frequency (F0). The mean scores for fundamental frequency, maximum Fo, minimum Fo, absolute jitter, jitter percentage, absolute shimmer, shimmer percentage for all patients were calculated and found increased immediately after therapy, compared with pre-therapy values. This shows if patients do the proper pushing excises than definitely they improve their voice quality. CONCLUSIONS: Early voice therapy may enable significant improvement in vocal function, allowing the patient to avoid surgery.
