A Randomized Controlled Trial With Female Teachers: Are there Differences Between and Within the Outcomes in Voice Therapy Groups With and Without Carryover Strategies?

The results showed that carryover strategies give no additional advantages in voice therapy. However, the decreasing trend in the Carryover group's voice complaints at follow-up would suggest that carryover strategies may have long-lasting effects. The results also confirm that voice therapy is efficient in improving voice-related quality of life.
