Efficacy of the Accent Method of Voice Therapy
There is an increasing need for studies of efficacy of behavior readjustment therapy procedures in human communicative disorders . Legal , social , scientific and professional considerations point up the need for more careful documentation of the effects of treatment techniques used by phoniatricians and speech- language pathologists . This study is conducted in order to evaluate the efficacy of the accent method of voice therapy ( AM ) . The AM is one of the holistic approaches for behavior readjustment voice therapy . It tackles collectively and simultaneously the various parameters of voice such as pitch , loudness and timbre . The results of intervention utilizing the AM in this clinical trial are assessed in a relatively controlled setup . Patients with voice problems result ing from various etiologic vocal pathologies are distributed r and omly into two groups . Group 1 ( G1 ) is given the full aspect of the AM , that is , voice hygiene advice plus the accent exercises to correct the faulty vocal technique ( habit ) . Group 2 ( G2 ) receives only voice hygiene advice . The AM is administered in individual sessions 20 min each , twice a week , while the voice hygiene advice counseling is given once a week . The assessment of the vocal pathology is done following a diagnostic protocol utilizing subjective as well as quasi- objective measures of evaluation . The initial assessment presents the baseline ( pretest ) data for both groups . The follow-up evaluations are done at mid intervention ( mid-test ) , that is , 10 sessions for G1 and 5 sessions for G2 , and at the termination of intervention/therapy ( post-test ) . The difference in improvement between G1 and G2 at the end of the observation was generally significant in favor of G1 . There were significant improvements in G1 in certain items specific for the various etiologic categories . The improvement from pretest to mid-test to post-test values followed a linear tendency . The significance of the results is discussed and the conclusions are outlined and criticized
