“…The association between increased muscle tension and acute and/or long-term stress has been affirmed by several studies both in laryngeal regions (Baker, Ben-Tovim, Butcher, Esterman, & McLaughlin, 2012;Baker, 2008;Dietrich & Verdolini Abbott, 2012;2014;Helou et al, 2013;Holmqvist, Santtila, Lindström, Sala & Simberg, 2013) and in neck and shoulders 1994, Lundberg, & Cooper, 2011. This relationship has been explained by Helou (2013) as "stress-induced acoustic changes in the voice are dynamic modifications to functions of respiratory, intrinsic laryngeal, extrinsic laryngeal, and the supralaryngeal muscles".…”

“…Tension in the neck and back may affects the function and balance of the voice production. Research regarding the etiology of MTD strongly supports the association between stress and muscle tension (Altman, Atkinson & Lazarus 2005;Baker, 2008;Dietrich et al, 2008;Dietrich & Verdolini Abbott 2012;Dietrich & Verdolini Abbott, 2014;Goldman, Hargrave, Hillman, Holmberg & Gress, 1996;Helou et al, 2013;Helou, 2014). The effect of acute stress on muscle tension in the larynx has been studied by Dietrich and Verdolini Abbott (2012;2014).…”

“…Especially the role of the ANS and/or SAM on the laryngeal muscles (Dietrich, 2008;Dietrich & Verdolini Abbott 2012;2014;Helou, Wang, Ashmore, Rosen, & Verdolini Abbott, 2013) and lower airways (Helou, 2014) has been studied in relation to these two frameworks. One way to further broaden the knowledge regarding the psychobiological pathways relevant for laryngeal functioning within these frameworks is to analyze the role of cortisol on voice symptoms, since the HPA-axis might have an effect on for example immunological changes.…”

Purpose: We investigated whether participants who reported more often occurring vocal symptoms showed higher salivary cortisol levels and if such possible associations were different for men and women. Method:The participants (N = 170; men n = 49, women n = 121) consisted of a populationbased sample of Finnish twins born between 1961 and 1989. The participants submitted saliva samples for hormone analysis and completed a web-questionnaire including questions regarding the occurrence of six vocal symptoms during the past 12 months. The data were analyzed using the Generalized Estimated Equations (GEE) method.Results: A composite variable of the vocal symptoms showed a significant positive association with salivary cortisol levels (p < .001). Three of the six vocal symptoms were significantly associated with the level of cortisol when analyzed separately (p-values below .05). The results showed no gender difference regarding the effect of salivary cortisol on vocal symptoms. Conclusions:There was a positive association between the occurrence of vocal symptoms and salivary cortisol levels. Participants with higher cortisol levels reported more often occurring vocal symptoms. This could have a connection to the influence of stress on vocal symptoms since stress is a known risk factor of vocal symptoms and salivary cortisol can be seen as a biomarker for stress.

“…Although these disorders are extremely common, little is known about their pathophysiology. In addition to poor vocal hygiene and other voice-use factors (Altman, Atkinson, & Lazarus, 2005;Van Houtte, Van Lierde, & Claeys, 2011), psychological factors (Roy, Bless, & Heisey, 2000a;Van Houtte et al, 2011), autonomic nervous system dysfunction related to stress management (Demmink-Geertman & Dejonckere, 2002;Helou, Wang, Ashmore, Rosen, & Abbott, 2013), and personality traits (Ng, Lo, Lim, Goh, & Kanagalingam, 2013;Roy & Bless, 2000;Roy, Bless, & Heisey, 2000b) have been implicated. However, there is no unifying framework for the etiology of hyperfunctional voice disorders or the contribution of these potential factors to their development.…”

Purpose: The vocal auditory-motor control of individuals with hyperfunctional voice disorders was examined using a sensorimotor adaptation paradigm. Method: Nine individuals with hyperfunctional voice disorders and 9 individuals with typical voices produced sustained vowels over 160 trials in 2 separate conditions: (a) while experiencing gradual upward perturbations in the fundamental frequency (f o ) of their auditory feedback (shift-up) and (b) under no auditory perturbation (control). The shift-up condition consisted of 4 ordered (fixed) phases: baseline (no perturbation), ramp (gradual increases in heard f o ), hold (a consistently higher heard f o ), and after-effect (no perturbation). Adaptive responses were defined as the difference in produced f o during control and shift-up conditions.Results: Adaptive responses were significantly different between groups. Individuals with typical voices generally showed compensatory adaptive responses, with decreased f o during the ramp and hold phases. Conversely, many individuals with hyperfunctional voice disorders instead displayed the opposite effect by following the direction of the perturbation. When f o was experimentally increased, speakers further increased their f o . Conclusion: Results indicate that some individuals diagnosed with hyperfunctional voice disorders have disrupted auditory-motor control, suggesting atypical neurological function. These findings may eventually allow for the development of new interventions for hyperfunctional voice disorders.

Functional Somatic Symptoms in Children and Adolescents

In this chapter we continue our exploration of the neuro biology of functional somatic symptoms by considering the skeletomotor system. When the stress system activates, the skeletomotor system acti vates in tandem, to prepare the body for protective action. And when protective action is no longer necessary, the skeletomotor system typi cally deactivates. But if the child has faced severe stress of one kind or another, with the consequence that stresssystem activation is main tained, activation of the skeletomotor system may also be maintained even though there is no immediate need. This maladaptive activation of the skeletomotor system may express itself in aberrant motor pat terns. Some of these patterns are easily recognizable as body responses to threat that have somehow remained activated even in the absence of current threat. Other motor patterns mimic neurological conditions and result in significant functional impairment. In this chapter we also 7

Intrinsic laryngeal muscle activity in response to autonomic nervous system activation

Abstract: Results are consistent with the suggestion that human laryngeal muscles exhibit an elevated level of activation concurrent with ANS activation, and endorse the putative link between laryngeal muscle tension and acute stress. Findings are replicable within a subset of three individuals.
