Association of Cannabis Inhalation With Voice Disorders: A Systematic Review
J. Meehan-Atrash, T. Korzun, & A. Ziegler
In press. August 8th, 2019 Issue of the Journal of the American Medical Association–Otolaryngology.
CONCLUSIONS: The findings suggest that cannabis-only smoking is associated with changes in vocal fold appearance, respiratory symptoms, and negative lung function changes, especially in heavy smokers. Details about patterns of cannabis consumption appear to be relevant to gather in patients with voice disorders. Results further suggest that cannabis smokers presenting with a voice disorder should undergo laryngeal imaging and complete pulmonary function testing when indicated and receive education about consumption methods and their association with voice disorders.
Phonation Demonstrates Goal Dependance in Unique Vocal Intensity and Workload Conditions
A. Ziegler, J. VanSwearingen, J. Jakicic, & K. Verdolini Abbott
In press in Journal of Speech, Language, & Hearing Research https://doi.org/10.1044/2019_JSLHR-S-18-0126
CONCLUSIONS: Mostly consistent with a theory of action, in which motor control is goal dependent (i.e., vocal SPL targets), speakers can achieve a loud vocal SPL despite increases in workload requirements. In contrast, laryngeal airway resistance stays relatively low when vocal SPL occurs spontaneously, suggesting glottal adjustments are made to improve gas exchange as metabolic respiratory requirements become prioritized. Metabolic respiratory requirements appear to be overcome by the overlay of motor control for voicing when a loud vocal SPL is targeted. The implication of goal-dependent phonation for clinicians is that real-world conditions (i.e., loud vocal SPL) matter in vocal testing and voice therapy.
Vocal Dose in Older Adults with Presbyphonia: An Analytic, Cross-sectional Study
A. Ziegler & E. Hapner
PMID: 30322822 DOI: 10.1016/j.jvoice.2018.09.005
CONCLUSIONS: Consistent with self-report, we found older adults with presbyphonia exhibit low time doses, which were in contrast to high vocal doses published on teachers, patients with dysphonia, and even office workers. We found differences in vocal dose as a function of sex and employment status. Though a limited sample, findings suggest patients with presbyphonia may demonstrate low vocal dose, which may be a useful target in treatment.
Effectiveness of Testosterone Therapy for Masculinizing Voice in Transgender Patients: A Meta-analytic Review
A. Ziegler, T. Henke, J. Wiedrick, & L. Helou
CONCLUSIONS: We found that not all transgender patients using testosterone therapy to masculinize voice should expect f0 lowering to cisgender male normative frequencies after 1 year. The vocal transition may involve voice problems for many patients, and some might not achieve voice-gender congruence without additional, voice-specific intervention. Given these findings, a voice evaluation should occur prior to initiating testosterone therapy and involve counseling on expectations for voice. Transgender patients who pursue voice masculinization may need management from laryngology and speech and language therapy to improve voice-gender congruence, mitigate voice problems, and increase satisfaction with voice.
Treatment Outcomes of Bilateral Medialization Thyroplasty for Presbylaryngis
J. Allensworth, K. O’Dell, A. Ziegler, L. Bryans, P. Flint, & J. Schindler
PMID: 29326026 DOI: 10.1016/j.jvoice.2017.10.014
CONCLUSIONS: Patients with presbylaryngis demonstrated significant improvement in both objective and subjective measures of vocal quality following bilateral medialization thyroplasty. These data suggest that medialization thyroplasty is a safe option that warrants consideration in the treatment of presbylaryngis.
Perceptions of Voice Therapy from Patients Diagnosed with Primary Muscle Tension Dysphonia and Benign Mid-membranous Vocal Fold Lesions
A. Ziegler, C. Dastolfo, R. Hersan, C. Rosen, & J. Gartner-Schmidt
PMID: 24841669 DOI: 10.1016/j.jvoice.2014.02.007
CONCLUSIONS: In this study, patients valued direct voice therapy in which they worked on altering vocal behaviors more than indirect voicetherapy that aimed to educate patients about their voice. Study findings suggest the importance of direct voice therapy and the need to incorporate carryover activities early on in the therapy process for greater treatment satisfaction and success.
Preliminary Data on Two Voice Therapy Interventions in the Treatment of Presbyphonia
A. Ziegler, K. Verdolini Abbott, M. Johns, A. Klein, & E. Hapner.
PMID: 24375313 DOI: 10.1002/lary.24548
CONCLUSIONS: Findings provide new evidence regarding the efficacy of voice therapy exercises in the treatment of age-related dysphonia and suggest PhoRTE therapy as another treatment method for improved voice-related quality of life and reduced perceived vocal effort in this population.
Health Promotion and Injury Prevention Education for Student Singers
A. Ziegler & M. Johns
Journal of Singing, 68(5): 531-541
CONCLUSIONS: The promotion of vocal health and prevention of vocal injury among singers is critical. An occupational health course such as the ones described in this report seems to satisfy one of the recommendations of the Health Promotion in Schools of Music project, namely, injury prevention education. However, more research is necessary to better understand how voice educators can serve the health needs of singing students.
Behavioral Treatment of Voice Disorders in Teachers
A. Ziegler, A. Gillespie, & K. Verdolini Abbott
CONCLUSIONS: Although data on the treatment of voice problems in teachers are still limited in the literature, emerging trends are noted. The accumulation of sufficient studies will ultimately provide useful evidence about this societally important issue.
Association Between the Electroglottographic Waveform and the Temporal Aspects of the Pharyngeal Swallow
H. Baylow, A. Ziegler, C. Ciorciari, & L.M. Ricigliano
J J Physical Rehab Med, 2(1): 019
CONCLUSIONS: There is preliminary support for the possible clinical application of electroglottography as a pharyngeal temporal measurement
tool in traditional dysphagia therapy.
