“…Of particular note, however, is the observation that the normal subjects tested by Beaty et al [48] consistently showed supraglottic dilation during 'progressively strenuous' exercise. Data traces from the subjects clearly suggested that the most dramatic vocal changes occurred during and just after the act of lifting the dumbbells, and indeed, many voice clinicians [e.g., [12][13][14][15] have stressed the importance of coordinating a patient's phonation with the point of maximal physical effort for the technique to be effective. This is different from the isometric steady-state lift in the present experiment or the push or pull against an immovable object as is commonly employed in voice therapy [e.g., 22,[26][27][28].…”

“…The maintenance of alveolar (and thus intratruncal) pressure during lifting has been shown to not only assist the support of the pectoral girdle, but also to alleviate part of the load on the vertebral column [8,9] . Even moderate levels of physical exertion may be associated with this type of 'adductory bias' [10][11][12] , which is why such effort closure or air-trapping activities as lifting, pushing, and pulling are commonly employed in therapeutic exercises for patients presenting with vocal hypofunction and/or glottal incompetence [13][14][15][16][17][18][19][20][21] .…”

Although effort closure techniques have a long history in the treatment of hypofunctional and psychogenic voice disorders, there have been surprisingly few studies of their specific laryngeal and phonatory effects. The present study was designed to provide preliminary data on physiologic changes in voice production associated with a weightlifting and support maneuver. Twenty vocally healthy subjects (10 men and 10 women) lifted hand-held weights and steadily supported them with outstretched arms as they either sustained comfortable phonation or repeated the syllable /pi/. Both the male and female subjects showed an increase in the electroglottographic contact quotient, long-term F₀ variability, and estimated laryngeal airway resistance attributable to an elevated driving pressure. Conversely, there were no significant changes in mean F₀, pitch perturbation quotient (jitter), or phonatory airflow between the pre-lift and lift portions of their voice production, regardless of the amount of weight supported. The results of this study indicate that simultaneous phonation and weightlifting is associated with increased laryngeal airway resistance characterized by an elevation in driving pressure and medial compression of the vocal folds. Implications for an improved understanding of normal vocal physiology and for the therapeutic use of such air-trapping exercises are addressed.

“…Special care was taken to increase vocal fold adduction without causing vocal hyperadduction and strain. Upper extremity pushing and lifting tasks [40,41] during phonation were initially implemented to increase vocal fold adduction, but were decreased as treatment progressed and subjects were able to generate improved loudness more easily. Maximum prolongation of 'ah' and maximum F 0 range drills were completed.…”

Thirty-five individuals with idiopathic Parkinson’s disease were enrolled in speech treatment. Twenty-two were enrolled in a high-effort phonatory-respiratory treatment program (Lee Silverman Voice Treatment, LSVT^®) and 13 were enrolled in a high-effort respiratory treatment program (RET). Perceptual judgments of speech loudness and quality were made independently by 6 listeners on recordings of the ‘Rainbow Passage’. These recordings had been obtained just before treatment (pre) and at 12 months’ follow-up (FU12). The speech samples in the LSVT group, but not in the RET group, were significantly more likely to be perceived ‘louder’ and ‘better quality’ at FU12 than at pre (p < 0.0001). These findings, along with others, suggest that the long-term effects of the LSVT are perceptible, clinically significant and treatment-specific.

“…Technically, the vocal rehabilitation of patients with an artificial vocal cord resembles in many respects the training of patients with unilateral vocal cord paralysis. The "pushing exercises" (Freeschels, Kaslein and Weiss [5]), which arc of great value in stim ulating glottal contact between a functioning and a paralyzed cord, were used only briefly and w ith great caution. The strong subglottic air pressure that a forceful glottic contact produces may put too much stress on the flap with the artificial vocal cord before firm scars have formed.…”
