Therapeutic effects of photobiomodulation in the speech-language-hearing clinic: an integrative literature review

ABSTRACT Purpose: to conduct a literature review on the therapeutic effects of photobiomodulation applicable to speech-language-hearing therapy. Methods: the databases searched were the Cochrane Library, Virtual Health Library, Medical Literature Analysis and Retrieval System Online (MEDLINE) via PubMed, and Web of Science/ISI.The selected articles were original ones whose abstracts were available and that evaluated the therapeutic effect of photobiomodulation in situations related to speech-language-hearing practice. Results: the sample comprised 23 articles, most of them being indexed in PubMed. The fields of health with the largest number of publications were Physical Therapy and Medicine. The sample size ranged from1 to 99 people, aged 15 to 77 years, and the most applied wavelength was the infrared one. Most of the studies had positive photobiomodulation application results - although in a few publications the effects of this treatment modality were assessed in a combination with rehabilitation exercises. Conclusion: photobiomodulation benefits different disorders treated by speech-language-hearing therapists, however, there is a broad methodological diversity, lacking specific protocols for the ideal dosimetry for each disorder.

摘要
研究目的：针对适用于言语语言听力治疗（speech-language-hearing therapy）的光生物调节（photobiomodulation）的治疗效果开展文献综述。
研究方法：本次检索的数据库包括Cochrane图书馆、虚拟健康图书馆、通过PubMed检索的在线医学文献分析与检索系统（MEDLINE）以及Web of Science/ISI。入选文献为可获取摘要的原创性研究，且需评估光生物调节在言语语言听力治疗相关场景中的治疗效果。
研究结果：最终纳入样本共23篇文献，其中大部分被PubMed收录。健康领域中发文量最高的为物理治疗学与医学。研究样本量介于1至99名受试者，受试者年龄跨度为15至77岁，最常使用的照射波长为红外波长。多数研究显示光生物调节应用取得了积极效果——尽管有少数文献将该治疗手段与康复训练相结合以评估其疗效。
研究结论：光生物调节对言语语言听力治疗师所诊疗的多种病症具有益处，但当前相关研究存在显著的方法学多样性，且缺乏针对各类病症的理想剂量学专用方案。
