RESUMO
Objective:To explore the effect of vocal training based on International Classification of Functioning, Disability and Health (ICF) and International Classification of Health Interventions (ICHI) on vocal function after vocal cord polyps. Methods:A framework of rehabilitation was developed with joint use of ICF and ICHI. From January, 2017 to December, 2018, 30 patients with vocal cord polyps and vocal dysfunction post operation were sampled. They accepted the therapy for a month, and assessed with Grade, Roughness, Breathiness, Asthenia and Strain scale (GRBAS), and measured acoustic parameters before and after operation, and after training, respectively. Results:The scores of GRBAS decreased after training, compared with those both before and after operation (F > 6.214, P < 0.05), as well as the acoustic parameters of fundamental frequency, fundamental frequency perturbation, normalized noise energy and amplitude perturbation (F > 9.655, P < 0.05). Conclusion:Vocal training based on ICF and ICHI is effective on vocal function after operation for vocal cord polyps.
