ObjectivesThe aim of this study was to review systematically the literature and to analyze the effectiveness of laryngeal manual therapy in addressing the overall severity of vocal deviation, the intensity of vocal and laryngeal symptoms, and musculoskeletal pain in adults with behavioral dysphonia.Study DesignThis is a systematic review and meta-analysis.MethodsTwo independent authors selected clinical trials that analyzed the effectiveness of laryngeal manual therapy compared with other interventions in the treatment of adults with behavioral dysphonia from the Cochrane Library, PubMed, Web of Science, and LILACS. The analyzed outcomes were the overall severity of vocal deviation, the intensity of vocal and laryngeal symptoms, and musculoskeletal pain. Data analysis was conducted based on the following steps: the assessment of the risk of bias, the measures of treatment effect and descriptive data analysis, the assessment of heterogeneity, subgroup analysis, sensitivity analysis, and the assessment of reporting biases.ResultsA total of 2135 studies were identified, three of which met the selection criteria. Data analysis showed an unclear risk of 100% of performance bias and 66% of detection bias, in addition to a 33% high risk of selection bias. Low statistical and clinical heterogeneities were found. In addition, no significant difference was found in the relative risk of improvement with laryngeal manual therapy and with other interventions in the analyzed outcomes.ConclusionsVarious types of laryngeal manual therapies are available with similar objectives and effects, but their effectiveness is equivalent to that of other interventions involving direct voice therapy in the rehabilitation of adults with behavioral dysphonia.

Tolerable delay for speech production and perception: effects of hearing ability and experience with hearing aids.

Tolerable delay for speech production and perception: effects of hearing ability and experience with hearing aids.

Int J Audiol. 2017 Aug 24;:1-8

Authors: Goehring T, Chapman JL, Bleeck S, Monaghan JJM

Abstract
OBJECTIVE: Processing delay is one of the important factors that limit the development of novel algorithms for hearing devices. In this study, both normal-hearing listeners and listeners with hearing loss were tested for their tolerance of processing delay up to 50 ms using a real-time setup for own-voice and external-voice conditions based on linear processing to avoid confounding effects of time-dependent gain.
DESIGN: Participants rated their perceived subjective annoyance for each condition on a 7-point Likert scale.
STUDY SAMPLE: Twenty normal-hearing participants and twenty participants with a range of mild to moderate hearing losses.
RESULTS: Delay tolerance was significantly greater for the participants with hearing loss in two out of three voice conditions. The average slopes of annoyance ratings were negatively correlated with the degree of hearing loss across participants. A small trend of higher tolerance of delay by experienced users of hearing aids in comparison to new users was not significant.
CONCLUSION: The increased tolerance of processing delay for speech production and perception with hearing loss and reduced sensitivity to changes in delay with stronger hearing loss may be beneficial for novel algorithms for hearing devices but the setup used in this study differed from commercial hearing aids.

More Infants are Benefiting from Newborn Hearing Screenings

A CDC Morbidity and Mortality Weekly Report found more infants are receiving documented newborn hearing screening and early intervention services. (2017;66[33]:888.) National early hearing detection and intervention (EHDI) data showed that the percentage of newborns who had documented newborn hearing screening increased from 52 percent to over 97 percent between 2000 and 2014. From 2005 to 2014, documented enrollment in early intervention from 2005 to 2014 among newborns who received documented screening increased from 58 percent to 65 percent. The number of infants lost to follow-up reduced both overall and in selected states. For example, only 4.6 percent of infants who did not pass newborn hearing screening in Massachusetts in 2014 were lost to follow-up, and 85 percent of newborns with diagnosed hearing loss were documented to have received intervention services.

​Early diagnosis of hearing loss, starting with newborn screening, has been shown to reduce deficits in receptive and expressive language that occur in unscreened children who subsequently receive a clinical diagnosis of hearing loss. (Pediatrics. 2016;137[1].) The authors of the report hope the lessons learned from the success of newborn hearing screening programs could be applied to early detection and intervention initiatives for critical congenital heart disease and other health conditions.​
