This systematic review aimed to evaluate the effects of singing as an intervention for aging voice.
Quantitative studies of interventions for older adults with any medical condition that involves singing as training were reviewed, measured by respiration, phonation, and posture, which are the physical functions related to the aging voice. English and Chinese studies published until April 2024 were searched using 31 electronic databases, and seven studies were included. The included articles were assessed according to the Grading of Recommendations, Assessment, Development, and Evaluations rubric.
Seven studies were included. These studies reported outcome measures that were related to respiratory functions only. For the intervention effect, statistically significant improvements were observed in five of the included studies, among which three studies had large effect sizes. The overall level of evidence of the included studies was not high, with three studies having moderate levels and the rest having lower levels. The intervention activities included trainings other than singing. These non-singing training items may have caused co-intervention bias in the study results.
This systematic review suggests that singing as an intervention for older adults with respiratory and cognitive problems could improve respiration and respiratory-phonatory control. However, none of the included studies covers the other two of the physical functions related to aging voice (phonatory and postural functions). The overall level of evidence of the included studies was not high either. There is a need for more research evidence in singing-based intervention specifically for patient with aging voice.
本系统评价旨在评估歌唱作为一种干预措施对老年嗓音的影响。
综述了针对任何患有与歌唱训练相关的呼吸、发声和姿势等与老年嗓音相关的身体功能的医学疾病的老年人的干预措施的定量研究。使用 31 个电子数据库搜索了截至 2024 年 4 月的英文和中文研究，共纳入了 7 项研究。根据推荐评估、制定和评估分级标准评估纳入的文章。
共纳入了 7 项研究。这些研究报告了仅与呼吸功能相关的结果测量指标。对于干预效果，纳入的 5 项研究中观察到统计学上显著的改善，其中 3 项研究具有较大的效应量。纳入研究的总体证据水平不高，其中 3 项为中等水平，其余为较低水平。干预活动包括除歌唱以外的训练。这些非歌唱训练项目可能导致研究结果存在混杂偏倚。
本系统评价表明，歌唱作为一种针对有呼吸和认知问题的老年人的干预措施，可能改善呼吸和呼吸发声控制。然而，纳入的研究均未涵盖与老年嗓音相关的另外两个身体功能（发声和姿势功能）。纳入研究的总体证据水平也不高。因此，需要针对老年嗓音患者进行更多基于歌唱的干预措施的研究证据。
