ABSTRACT
Objective:To compare the effects of remote interactive voice therapy versus traditional in-person therapy on treatment adherence and clinical outcomes in patients with voice disorders. Methods:A retrospective historical control study was conducted, categorizing patients into three groups based on distinct periods of COVID-19 prevention policies: the 2019 traditional therapy group（n=82）, the 2021 traditional therapy group（n=43）, and the 2022 remote therapy group（n=54）. Adherence differences were analyzed by geographic subgroup（Guangzhou vs. non-Guangzhou）, and improvements in Voice Handicap Index（VHI）, jitter, and shimmer were compared pre-and post-treatment. Results:Adherence: The overall〓adherence rate in the 2022 remote therapy group（38.89%） was higher than in the 2019（31.71%） and 2021（23.26%） traditional groups, although the difference was not statistically significant（P>0.05）. Notably, non-Guangzhou patients exhibited significantly higher adherence with remote therapy（2022: 45.45%） compared to traditional therapy（2019: 5.00%; 2021: 0）（P<0.01 for both comparisons）. Efficacy: Among patients with good adherence, all three groups showed significant improvements in VHI, jitter, and shimmer（all P<0.01）. Further analysis revealed no statistically significant differences in the magnitude of improvement between the 2022 remote group and the 2019/2021 traditional groups（all P>0.05）, indicating comparable therapeutic efficacy. Conclusion:Remote interactive voice therapy significantly enhances adherence among non-local patients, with equivalent efficacy to traditional in-person therapy. This approach provides an effective solution to overcome spatial and temporal barriers in voice rehabilitation, and holds important practical significance for optimizing voice disorder management strategies and improvinghealthcare service accessibility.
