Aerodynamic and acoustic voice measurements of patients with vocal nodules: variation in baseline and changes across voice therapy

Intensive Versus Traditional Voice Therapy for Vocal Nodules: Perceptual, Physiological, Acoustic and Aerodynamic Changes

“…8 The decrease in strained voice may also be reflected Although significant improvements were noted by the end of treatment, for the majority of the participants, their vocal nodules had not completely resolved, as has been observed by other researchers. 5,8 It is postulated that although the trauma to the vocal folds may have decreased after therapy, the impact on the vocal fold physiology might not have been significant enough to allow complete amelioration of the nodular lesions. 5,8 It is also suspected that those with larger nodules may require a longer care period.…”

“…[2][3][4] Individuals with vocal nodules constitute a large part of the client population at voice clinics. 5 The voice disturbances can cause personal problems and societal losses, as individuals with vocal nodules in professions with high voice demands are forced to take long periods of sick leave and sometimes may have to change careers. 5,6 As a consequence, extensive research has been conducted on the efficacy of treatment for vocal nodules, with voice therapy recommended as first-line treatment.…”

Thirty-one participants were recruited to the intensive voice program.…”

Estimating Subglottal Pressure From Neck-Surface Acceleration During Normal Voice Production

“…Subglottal pressure has been used clinically to differentiate individuals with typical voices from those with voice disorders and to act as a clinical outcome measure (Hartl, Hans, Vaissière, Riquet, & Brasnu, 2001;Hillman, Holmberg, Perkell, Walsh, & Vaughan, 1989;Holmberg, Doyle, Perkell, Hammarberg, & Hillman, 2003;Jiang & Stern, 2004;Speyer, 2008;Zeitels, Hillman, Franco, & Bunting, 2002;Zeitels, Hochman, & Hillman, 1998;Zeitels et al, 2009). In addition, subglottal pressure is a central component of vocal efficiency (Björklund & Sundberg, 2016;Colton, Casper, & Leonard, 2006;Titze, 1992Titze, , 2013Titze, Maxfield, & Palaparthi, 2016) and is associated with aspects of perceived vocal effort (Ramig & Dromey, 1996;Rosenthal, Lowell, & Colton, 2014).…”
