During sensory testing for light touch, which statement is true?

• A. You should always test on both sides at the same time to save time.
• B. You should compare bilaterally to the other side.
• C. You should never use a cotton ball or brush.
• D. You should always apply in a patterned sequence.

Answer: (B)

In light touch testing, the important practice is to assess symmetry by comparing one side of the body to the other. This bilateral comparison helps reveal unilateral deficits that might be missed if you test each area without a reference. The true statement emphasizes this approach: you should compare bilaterally to the other side. By testing the same locations on both sides and noting any differences in sensation, you can identify areas of sensory loss or alteration more reliably. Using a cotton ball or brush is a common and appropriate tool for light touch, and testing is typically done side by side to detect asymmetry rather than attempting to test both sides at once. There’s no requirement to follow a fixed patterned sequence; the key is consistency and accurate bilateral comparison to locate deficits.
