Patients with pMTD report increased vocal effort, fatigue, discomfort, and odynophonia. Although laryngeal and paralaryngeal muscle tension and hyperfunction are the most commonly proposed mechanisms underlying these symptoms, recent studies suggest pMTD may have more to do with the somatosensory system. However, relationships between voice symptoms and somatosensory mechanisms are poorly understood, creating challenges for mechanistic-based pMTD management. The first objective was to compare laryngeal, paralaryngeal, and global somatosensation between subjects with and without pMTD. The second was to determine relationships between pMTD symptoms and somatosensation.</p><p><strong>Methods: </strong>Fifty-two (20 pMTD and 32 control) subjects underwent laryngeal sensory testing with aesthesiometers, as well as peripheral mechanosensory and dynamic temporal summation testing to paralaryngeal and limb regions. Voice symptom severities (vocal effort, fatigue, discomfort, and odynophonia) were collected on 100-mm visual analog scales before and after laryngeal sensory testing. Participants also completed the Central Sensitization Inventory.</p><p><strong>Results: </strong>Patients with pMTD reported significantly higher laryngeal sensations (P = 0.0072) and voice symptom severities (P < 0.001) compared with the control group, and had significantly more vocal tract discomfort postlaryngeal sensory testing compared with the prelaryngeal sensory testing timepoint (P = 0.0023). However, there were no significant group differences in laryngeal airway protection responses suggestive of peripheral laryngeal hypersensitivities (P = 0.444). There were also no significant group differences on paralaryngeal or global sensitivities (P > 0.05), and no correlations between severity of voice symptoms and perceptual laryngeal sensations or hypersensitivities (P > 0.05).</p><p><strong>Conclusion: </strong>Patients with pMTD perceive more sensitivities in the larynx and feel more sensations related to the voice (vocal effort, fatigue, discomfort, and pain). However, in general, patients with pMTD do not have abnormal peripheral laryngeal hypersensitivities, increased global somatosensation, or heightened central sensitivity. The lack of significant correlations between peripheral laryngeal hypersensitivities and voice symptom severity ratings suggests these outcome variables target distinct mechanistic constructs.</p>","PeriodicalId":49954,"journal":{"name":"Journal of Voice","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142114173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study utilizes HSV to investigate supraglottic laryngeal tissue maneuvers obstructing the view of the vocal folds, in AdLD and normophonic speakers during connected speech.

However, little is known about what factors influence the terminology that SLPs choose to use. Understanding this gap is important to ultimately optimize voice therapy outcomes. Therefore, the primary aims of this study were to (1) assess the relationship between reported clinician-perceived positivity and (2) assess the relationship between clinician-perceived positivity and clinical endorsement for use. We hypothesized that clinician-perceived positivity would be one important factor driving how frequently clinicians use or avoid specific terms, and if they think the term should be used by other SLPs in clinical practice.</p><p><strong>Design/methods: </strong>This prospective study was conducted as an online survey of SLPs and SLP clinical fellows who evaluate and treat adult voice patients. The survey presented respondents with a total of 46 voice-related terms and prompted respondents to rate: (1) how frequently they use a specific voice-related term (\"frequency of use\"); (2) how positive or negative they perceive a specific voice-related term to be (\"perceived positivity\"); and (3) if they feel a specific voice-related term should versus should not be used in clinical practice (\"clinical endorsement\").
