Objectives: After studying the article entitled “Muscle Quality, Measured by Ultrasound-Derived Corrected Echo Intensity, Does not Affect Changes in Cross-sectional Area of the Vastus Lateralis Following Recumbent Rest,” you will be able to:
Discuss the use of ultrasound in muscle assessment
Interpret the effect of recumbent rest on muscles
Explain the importance of cross-sectional area and echo intensity in muscle assessment
Ultrasound assessment of muscle size and shape is typically performed in which position? Trendelenburg Prone Recumbent Fowler’s
With the transition of standing to supine position: Blood relocates from abdomen to legs Muscle size increases in the lower body Muscle cross-sectional area increases Blood relocates from the legs to the abdomen
No change in muscle size after recumbent rest is observed in which individuals? Teenagers Inactive Active Middle-aged
Which content is said to cause the greatest change in muscle size following recumbent rest? Water Fat Fibrous tissue Connective tissue
Echo intensity: Measures refraction of ultrasound waves Uses an invasive approach to measuring muscle composition Analyzes pixels in an area of interest Decreases with age
According to this study, 15 minutes of recumbent rest shows which change to cross-sectional area? Decreases Increases No change Did not discuss
Which of the following is the correct statement regarding this study? Individuals with the lowest and highest muscle quality differ significantly in muscle size Muscle quality is solely dependent on age Subcutaneous fat tissue has no effect on echo intensity of tissues Echo intensity is artificially decreased in deeper tissues
The downfall of using ultrasound in assessing muscle is: Accessibility Affected by confound factors Cost Unable to assess muscle size
The purpose of the study was to determine: Whether the rest-induced decrease in cross-sectional area was due to echo intensity How much intracellular fluid moves out of muscle cells in recumbent position That ultrasound was the best method to determine muscle quality Whether recumbent position decreases blood relocation from the legs to the abdomen
Participants of the study: Drank 72 ounces of water prior to the test Obtained a body composition assessment Exercised vigorously the day of the examination Were older than 35 years of age
