Frequency modulation (FM) system in auditory processing disorder: an evidence-based practice?
BACKGROUND
use of frequency modulation (FM) system in auditory processing disorder.


OBJECTIVE
to verify the existence of scientific evidence confirming the effectiveness of personal FM systems in the treatment of central auditory processing disorders (APD). For this purpose a systematic review of the literature was made, using data found in electronic databases (Medline, Lilacs and Cochrane library) as well as on the internet. The articles retrieved were analyzed according to the CONSORT statement and then classified by their evidence level.


CONCLUSIONS
the search resulted in 1,589 references out of which only 19 met the inclusion criteria. All of the analyzed articles were classified as having low level of evidence (expert opinion or case studies). Strong scientific evidence supporting the use of personal FM systems for APD intervention was not found. Since such device is frequently recommended for the treatment of APD, it becomes essential to carry out studies with high scientific evidence that could safely guide clinical decision making on this subject.
