Reliability of Measuring Geniohyoid Cross-Sectional Area with B-Mode Ultrasound.

B-mode ultrasound is a safe noninvasive procedure that has been used to characterize aspects of the oropharyngeal swallow. The submental suprahyoid muscles are often investigated with ultrasound because of their contributions to hyolaryngeal elevation. There are several techniques for positioning the ultrasound transducer in the coronal plane, however, there is limited research on how reliability of measurement of the cross-sectional area (CSA) of the geniohyoid differs across transducer placement technique.

Association of Tongue Strength and Maximum Incisal Opening with Oral Intake in Persons with Head and Neck Cancer Treated with Radiotherapy: A Retrospective Study.

Persons treated with radiotherapy (RT) for cancer of the head and neck (HNC) may experience limited oral intake at treatment completion. The purpose of this retrospective study was to examine the contributions of tongue strength and maximum incisal opening (MIO) to oral intake in a cohort of veterans treated for HNC. Medical records of veterans diagnosed with HNC treated with RT who were seen by the Speech Pathology Service prior to and throughout treatment per usual care were reviewed for this study; eighty-two records met the inclusion criteria for analysis.

Ultrasonography as Biofeedback to Increase Muscle Activation During the Mendelsohn Maneuver in Healthy Adults.

The Mendelsohn Maneuver (MM) is a therapeutic strategy that targets reduced laryngeal elevation. Both clinicians and clients identify the MM as one of the more difficult interventions to teach and learn. The purpose of this study was to examine the effect of applying real-time ultrasound as visual feedback in teaching the MM to healthy adults.

Using Ultrasound to Document the Effects of Expiratory Muscle Strength Training (EMST) on the Geniohyoid Muscle.

Expiratory muscle strength training (EMST) is an exercise program designed to strengthen the muscles of expiration by increasing expiratory load during breathing exercises using either resistive or pressure threshold devices. Previous research has shown that EMST may increase submental suprahyoid muscle activity as measured with surface electromyography. The impact of EMST on submental muscles is of interest to those who treat dysphagia.

Swallowing Patterns in the HNC Population: Timing of Penetration-Aspiration Events and Residue.

Objective: This study described swallowing patterns in a large head/neck cancer (HNC) cohort.

Study Design: In a retrospective review of data from a randomized controlled trial, we studied timing of penetration events as they related to aspiration and oral/pharyngeal residue.

Setting: Retrospective review of a multicenter randomized controlled trial.
