Summary
Speech-language pathologists' palpation ratings of hyolaryngeal excursion may predict upward hyoid movement during swallowing. This clinical swallow evaluation finding suggests palpation offers insights into superior hyolaryngeal excursion during assessments.
Area of Science:
- Swallowing disorders
- Clinical audiology
- Speech-language pathology
Background:
- Clinical swallow evaluation (CSE) is crucial for diagnosing dysphagia.
- Hyolaryngeal excursion (HLE) is a key indicator of swallow function.
- Instrumentation-based measures (iHLE) provide spatial data, but palpation (pHLE) is a common clinical assessment tool.
Purpose of the Study:
- To investigate if speech-language pathologists' (SLP) palpated hyolaryngeal excursion (pHLE) ratings predict instrumentation-based hyolaryngeal excursion (iHLE) measures.
- To determine the predictive value of palpation in assessing superior and anterior hyoid movement during swallowing.
Main Methods:
- Adults (18-99 years) underwent CSE with pHLE ratings and videofluoroscopy swallow studies (VFSS) for iHLE.
- Four SLPs rated pHLE during CSE.
- Multiple linear regression analyzed the relationship between pHLE, bolus consistency, swallow number, and iHLE (hyoid peak elevation).
Main Results:
- Palpation, bolus consistency, and number of swallows significantly predicted superior (upward) hyoid peak position.
- No tested factors significantly predicted anterior (forward) hyoid peak position.
- Data from 77 volunteers (44 female, mean age 71.6) were analyzed.
Conclusions:
- Palpation during CSE may offer valuable insights into superior hyolaryngeal excursion.
- Further research is needed to confirm if palpation enhances SLPs' diagnostic accuracy and clinical decision-making in swallow assessments.

1.5K
Physical assessment of the respiratory tract is critical in identifying potential health issues. One key component of this assessment is palpation, a technique healthcare providers use to assess the body for abnormalities. This content explores the method of palpation in evaluating the respiratory tract, focusing on thoracic palpation and tactile fremitus.

01:23Assessment of the Abdomen III: Palpation
3.0K
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...
