Introduction: In general, voice therapy is given on one-to-one basis where each individual is provided therapy by the clinician individually. On the other hand, in group therapy, the treatment is provided to a group of individuals with a similar disorder. Need of the Study: There was a need to conduct this study as there are very few studies on finding the efficacy of group therapy for hyperfunctional voice disorder among teachers especially in India. Aim: The primary aim of the study was to find out the efficacy of group voice therapy in hyperfunctional voice disorders among teachers. The secondary aim was to compare the outcome of group therapy and individual therapy in hyperfunctional voice disorder among teachers. Methodology: Totally 16 individuals in the age range between 25 and 45 years who were teachers by profession with hyperfunctional voice disorder were enrolled in the study. Two age and gender-matched groups were constituted. Group A consisted of eight (6 males and 2 females) individuals with a mean age of 35.6 years. Group B was comprised of eight (6 males and 2 females) with a mean age of 34 years. Group A was enrolled into group therapy while Group B was enrolled into individual voice therapy. The participants underwent a clinical voice evaluation including auditory-perceptual and quality of life assessment using Grade, Roughness, Breathiness, Asthenia, Strain scale, Dr. Speech software and Voice Handicap Inventory. Voice therapy protocol included 12 sessions once a week. It consisted of 15 min. of indirect and the rest 45 min. of Lessac-Madsen Resonant voice Therapy. Posttherapy measures were taken for both the groups. Results and Discussion: Results showed significant improvement post voice therapy in acoustic analysis measures, i.e. jitter and shimmer in both the groups. In perceptual measures, there was a significant improvement in Grade, Roughness, and Strain measures in both the groups while in quality of life measures there was significant improvement post-therapy in both the groups. When compared between groups A and B there was no significant difference in all the measures in both pre- and post-therapy assessments. Our study has recruited the control group and found there was no significant difference between the individual versus group voice therapy. Conclusion: Group voice therapy is as effective in the treatment of hyperfunctional voice disorders as individual therapy. There is a need to get data on a larger population to generalize the findings.
