- ItemAcesso aberto (Open Access)A eficácia do treinamento auditivo formal em adultos com distúrbio do processamento auditivo (central)(CEFAC Saúde e Educação, 2013-12-01) Cruz, Ana Carolina Almendra; Andrade, Adriana Neves de [UNIFESP]; Gil, Daniela [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)PURPOSE: to compare the performance of adults with auditory processing disorder in behavioral tests before and after formal auditory training, in order to verify the effectiveness of this approach. METHODS: this is a quantitative retrospective study for which we selected 18 individuals with auditory processing disorders evidenced by the behavioral assessment, aged between 16 and 38 years old. All subjects underwent a formal auditory training program conducted in eight sessions of 45 minutes each, twice a week. Sessions were organized in ascending order of complexity of the listening skills srech as, auditory closure, figure-ground for sentences, words, syllables and sounds and nonverbal temporal processing of sounds (analysis of the intensity, duration and frequency). For statistical purposes the results of the SSW test SSI (ICM) and Duration and frequency pattern recognitive obtained before and after auditory training, considering the ear and sex variables. RESULTS: there were no statistically significant differences between the right and left ears. Both men and women when analyzed separately showed better results in post-training. These differences were statistically significant in for duration and frequency pattern tests, for men and women. In SSW improvement in male and SSI R / S -15 females, respectively. In addition, all subjects reported better attention and better communicative performance after auditory training. CONCLUSION: the formal auditory training improves listening skills figure - ground for verbal sounds and temporal processing measured by behavioral tests in adults diagnosed with auditory processing disorders.
- ItemAcesso aberto (Open Access)Formal auditory training in adult hearing aid users(Faculdade de Medicina / USP, 2010-01-01) Gil, Daniela [UNIFESP]; Iorio, Maria Cecilia Martinelli [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)INTRODUCTION: Individuals with sensorineural hearing loss are often able to regain some lost auditory function with the help of hearing aids. However, hearing aids are not able to overcome auditory distortions such as impaired frequency resolution and speech understanding in noisy environments. The coexistence of peripheral hearing loss and a central auditory deficit may contribute to patient dissatisfaction with amplification, even when audiological tests indicate nearly normal hearing thresholds. OBJECTIVE: This study was designed to validate the effects of a formal auditory training program in adult hearing aid users with mild to moderate sensorineural hearing loss. METHODS: Fourteen bilateral hearing aid users were divided into two groups: seven who received auditory training and seven who did not. The training program was designed to improve auditory closure, figure-to-ground for verbal and nonverbal sounds and temporal processing (frequency and duration of sounds). Pre- and post-training evaluations included measuring electrophysiological and behavioral auditory processing and administration of the Abbreviated Profile of Hearing Aid Benefit (APHAB) self-report scale. RESULTS: The post-training evaluation of the experimental group demonstrated a statistically significant reduction in P3 latency, improved performance in some of the behavioral auditory processing tests and higher hearing aid benefit in noisy situations (p-value < 0,05). No changes were noted for the control group (p-value <0,05). CONCLUSION: The results demonstrated that auditory training in adult hearing aid users can lead to a reduction in P3 latency, improvements in sound localization, memory for nonverbal sounds in sequence, auditory closure, figure-to-ground for verbal sounds and greater benefits in reverberant and noisy environments.
- ItemAcesso aberto (Open Access)Índice percentual de reconhecimento de sentenças no silêncio e no ruído: efeitos da aclimatização no indivíduo avaliado sem as próteses auditivas(CEFAC Saúde e Educação, 2010-10-01) Santos, Sinéia Neujahr Dos; Petry, Tiago; Costa, Maristela Julio [UNIFESP]; Universidade Federal de Santa Maria; Centro Universitário Feevale; Universidade Federal de São Paulo (UNIFESP)PURPOSE: to check the effect of acclimatization on sentence recognition in quiet environment and under noise, in new users of hearing aids, evaluated without their use, before and after the acclimatization period. METHODS: the study comprised 40 individuals, aged between 28 and 78year old with mild to moderate sensorineural hearing loss. They were starting the selection and adaptation process of hearing aids. The tests were conducted in three sessions, before the adaptation of hearing aids, fourteen days and three months later, respectively. they were applied to Portuguese Sentences Lists test (COSTA, 1997), in free field, in quiet environment and under noise, both in fixed 65 dB A intensity, in which we obtained the percentual indexes of sentences recognition in quiet environment (PISRQ) and under noise (PISRN). RESULTS: the mean values for PISRQ in the 1st, 2nd and 3rd sessions were, respectively, 65%; 72% e 83% dB A. The mean values of PISRN for the 1st, 2nd and 3rd sessions were 51%; 58% e 59% dB A, respectively. While comparing the results between sessions, there was a statistically significant difference for PISRQ between the 1st and 3rd e and between the 2nd and 3rd session, and for PISRN, between the 1st and 2nd e and between the 1st and 3rd session. CONCLUSION: the subjects improved their performance using hearing aids, even being evaluated without them, and this improvement may be related to the acclimatization effect.
- ItemAcesso aberto (Open Access)Treinamento auditivo formal em adultos com deficiência auditiva(Universidade Federal de São Paulo (UNIFESP), 2006-01-31) Gil, Daniela [UNIFESP]; Iorio, Maria Cecilia Martinelli [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Objective: To verify the effects of a formal auditory training program in adult hearing aid users with mild to moderate sensorineural hearing loss using behavioral auditory processing tests, a self-report benefit scale and long latency auditory evoked potential – P300. Method: Fourteen intra-aural hearing aid users were divided into two groups: seven with auditory training and seven without auditory training. Subjects from experimental group have undergone a formal auditory training program with hearing aids, organized in eight sessions of 45 minutes each, twice a week, aiming at improving auditory closure, figure-to-ground for verbal and nonverbal sounds and temporal processing (frequency and duration of sounds) skills. The program itself and the activities within the session were proposed in progressive complexity in order to challenge the auditory system. Auditory training efficiency was verified by evaluating all subjects in two different occasions: pre and post-training in the Experimental Group and in the initial and final evaluations in the Control Group, including electrophysiologic and behavioral auditory processing evaluations and the application of the self-report benefit scale APHAB. Results: Neither amplitude and latency of P300 nor the behavioral central auditory tests used revealed significant differences for the right or left ears. In the post-training evaluation Experimental Group presented statistically significant reduction in P3 latency, improved performance in all behavioral auditory processing tests and higher benefit in noisy situations as demonstrated in the self-report benefit scale APHAB than the Control Group. Conclusions: We could conclude that formal auditory training in adult hearing aid users lead to reduction in P3 latency; improvements in memory for verbal and nonverbal sounds in sequence, auditory closure, figure-to-ground for verbal sounds and higher benefit in reverberant and noisy environments
