Abstract
PurposeTo determine the efficacy of a hybrid group telepractice program in voice therapy for primary school teachers. MethodThe participants, consisting of 12 teachers with voice disorders (3 males and 9 females), participated in 11 sessions of the telepractice program, divided into 1 training session on vocal hygiene, 5 practice sessions by themselves, and 5 group practice sessions in 5 weeks. Data on the vocal handicap index (VHI) measure was obtained pre- and post-intervention. The voice analysis included fundamental frequency (local), jitter (local), shimmer (local), harmonic-to-noise ratio (local), and maximum phonation time assessed by Praat software. ResultThe VHI assessment revealed a statistically significant difference (p < 0.05) in the emotional domain. There was no statistically significant difference (p > 0.05) in physical, functional, and total scores. Both males and females had no statistically significant difference (p > 0.05) in mean fundamental frequency. However, there was a statistically significant difference (p < 0.05) in jitter (local), shimmer (local), harmonics-to-noise ratio (local), and the maximum phonation time. ConclusionThe group telepractice program in voice therapy for primary school teachers was effective. It could be utilized for voice therapy to prevent voice disorder problems in teachers.
