Final answer:
Tactile fremitus is assessed by using an oscillating tuning fork and testing the patient's perception of the stimulus movement. Proprioception is also tested by asking the patient if they can sense finger or toe movement.
Step-by-step explanation:
Tactile fremitus is assessed by placing an oscillating tuning fork against prominent bone features on the patient's body, such as the distal head of the ulna on the medial aspect of the elbow. The patient is then asked to perceive the direction in which the stimulus is moving. This test is repeated in different locations and for different dermatomes to assess the spatial specificity of perception. Proprioception, the sense of position and motion, is tested by moving the fingers or toes and asking the patient if they sense the movement.
