How is the sensation in the lower extremities typically assessed?

• A. By using a monofilament or tuning fork testing
• B. By checking pulse strength in the femoral artery
• C. By conducting a range of motion assessment
• D. By observing skin temperature variations

Answer: (A)

Sensation in the lower extremities is typically assessed using methods that directly evaluate the ability to feel stimuli, including light touch, pain, vibration, and temperature. One common technique used is monofilament testing, where a fine filament is pressed against the skin to determine the patient's ability to feel light touch in specific areas. Tuning fork testing is another method used to assess vibratory sensation by placing a vibrating fork on bony prominences and asking the patient if they can feel the vibration.

These methods are essential for identifying sensory deficits that may result from conditions such as neuropathy, peripheral artery disease, or other neurologic conditions.

While checking pulse strength in the femoral artery is important for assessing blood flow and vascular health, it does not provide direct information about sensory function. Conducting a range of motion assessment evaluates joint mobility and muscle function rather than sensation. Observing skin temperature variations can give clues about blood flow or inflammation but is not a standardized method for assessing sensation itself.
