Which tests are used to assess sensation in the UE nerves evaluation?

• A. Tinel's Sign and Phalen's Test
• B. Jebsen-Taylor Test
• C. Grip Strength and Pinch Strength
• D. Semmes Weinstein Monofilament and 2 Point Discrimination

Answer: (D)

Sensation testing in the upper extremity nerves focuses on how well touch and protective sensation are preserved across nerve distributions. The Semmes-Weinstein Monofilament test uses calibrated filaments pressed against the skin to determine the light touch and protective sensation threshold. The 2-point discrimination test measures how finely a person can distinguish two close points of contact, reflecting the density and function of sensory receptors and nerve fibers in a given area. Together, these tests directly assess sensory integrity along peripheral nerves. The other options target different aspects: provocative signs like Tinel’s and Phalen’s identify nerve irritation or compression symptoms rather than precise sensory thresholds; Jebsen-Taylor assesses functional hand dexterity; grip and pinch strength evaluate motor strength rather than sensation.
