The samples were maintained in an aerated Krebs-Ringer solution and curarized. Temperature and pH were controlled. Field stimulation was performed with parallel-plate platinum electrodes. Using a dual mode ergometer, in vitro measurements were made at increased levels of strain. Least-squares regression analyses were performed on contraction times and 50% relaxation times as a function of strain. Results of this investigation indicated important differences in the active and passive properties of the pars recta portion of the cricothyroid and the vocalis muscle. The mean contraction time of the vocalis muscle was 24 ms and that of the cricothyroid muscle, 33.5 ms. The mean half relaxation time was 20 ms for the vocalis muscle and 30 ms for the cricothyroid. The twitch contraction and half relaxation times of the vocalis remained independent of strain, whereas those of the cricothyroid showed strong positive dependence on strain level. Differences in the passive properties of the two muscles were also evidenced; the vocalis muscle was found to be stiffer at all levels of strain.

Effects of bolus volume, bolus viscosity, age, and gender were analyzed, and dry and bolus swallows were compared. The duration of the intrabolus pressure, reflecting the pressure exerted by the tongue on the bolus and preceding the generation of the pharyngeal pressure, was significantly affected by bolus volume. The duration of oropharyngeal pressure was affected by age, gender, and bolus type (bolus vs. dry swallow). Peak oropharyngeal pressure was not affected by any of the test factors, although there was a tendency for older subjects to have higher pressures than young subjects.

Two separate portions of the cricothyroid muscle, namely the pars recta and pars oblique, were studied. Samples of the muscle were dissected from dog larynges excised a few minutes before death and kept in Krebs-Ringer solution at a temperature of 37 degrees +/- 1 degrees C and a pH of 7.4 +/- 0.05. Tetanic contraction of the muscle samples was obtained by field stimulation to the muscle through a pair of parallel-plate platinum electrodes and with a train of square pulses of 0.1-millisecond duration and 85-V amplitude. Isometric force responses of the pars recta and pars oblique muscles were obtained electronically with a dual servo system (ergometer). The effect of tissue elongation on the active and passive responses was quantified by stimulation of the sample during cyclic elongation. Both active and passive responses as a function of elongation were obtaine...

Fifteen normal, healthy, young adults (20-29 years of age) were connected to a respirodeglutometer and positioned for simultaneous videofluoroscopic assessment in the lateral plane. Subjects performed three swallows each of a 5-ml and a 10-ml bolus of liquid barium and a 5-ml bolus of paste barium, for a total of nine swallows per subject. Location of the bolus head as identified with videofluoroscopy was associated with eight respirodeglutometric variables. In addition, temporal relations for seven respirodeglutometric variables were calculated as a function of bolus volume and viscosity. Significant temporal differences were found for five of the variables by volume. No significant temporal differences were noted by viscosity. Expiration occurred before 79% and after 96% of the swallows. The number of inspirations preceding...

Larynges were excised from anesthetized dogs, immediately submerged in a Krebs-Ringer solution, and aerated with 95% oxygen and 5% carbon dioxide. The tissue was maintained in the aerated electrolyte solution throughout the experiment. The vocalis muscle was carefully dissected, with attachments to the arytenoid and thyroid cartilages maintained. The preparation was then subjected to isometric (constant length) force-elongation measures, which were converted to stress-strain values. Stage I of the investigation identified the dog model with the least intrastudy variability relative to the age, sex, and breed of the research animal, as well as to the effects of curare. Stage II investigated the effects of different instrumentation, definitions of reference length, methods of elongation, and effects of electrical stimulation. Once the procedure ha...

Samples of the vocalis muscle were dissected from dog larynges excised a few minutes before death and kept in Krebs solution at a temperature of 37 +/- 1 degree C and a pH of 7.4 +/- 0.05. Isometric and isotonic tetanic responses of the vocalis muscle were obtained electronically with a Dual Servo System (ergometer). Isometric tension was recorded at various levels of elongation and stimulation rate. Isotonic shortening was recorded at various levels of force, and shortening velocity was obtained by numerical analysis of recorded data. It was found that fused tetanus occurred at stimulation rates of about 90 Hz, where the isometric tetanic force saturates. Repeated stimulation of the muscle in vitro not only caused nonrecoverable fatigue in the tissue, but also decreased its passive tension. The combined active and passive isometric tension increased with elongatio...

Bipolar hooked wire electrodes were inserted in the superior pharyngeal constrictor muscle of 15 healthy subjects. Electrode placement was controlled. Each subject performed two reflexive tasks, six voluntary tasks requiring phonation, and four nonspeech voluntary tasks. The electromyogram (EMG) was rectified and integrated. The resulting number was then transformed by taking its natural logarithm. An ANOVA was performed and a linear model was estimated. The magnitude of the EMG activity was related to the location of the electrodes. The largest values were recorded in the lateral-superior placement, followed by the lateral-inferior, medial-inferior and medial-superior. The superior pharyngeal contrictor was found to be a muscle activated primarily during refle...

The relationship between vallecular residue and oral-stage dysphagia, reduced hyoid elevation, and movement of the epiglottis was assessed in 330 patients referred to the speech pathology section for evaluation of oropharyngeal swallowing function. Patients with vallecular residue were more likely to have oral involvement or deviant epiglottic function, characterized by an absence of epiglottic inversion or incomplete inversion, than patients without vallecular residue. Although the primary focus of the study was between vallecular residue and the other select variables, the interrelationships among the three other variables were also studied. Patients with deviant epiglottic function were more likely to have oral involvement, reduced hyoid elevation, or vallecular residue than patients without deviant epiglottic function and patients with reduced hyoid elevati...
