Altered sensory processing can be assessed with which method?

• A. Goniometry
• B. MRI
• C. EMG
• D. Pressure algometry

Answer: (D)

Assessing altered sensory processing is about measuring how the nervous system perceives sensory input, especially pain. Pressure algometry does this by applying a controllable pressure to a point on the body and determining the pressure level at which the sensation changes to painful. This gives a pressure pain threshold that reflects how sensitively the nervous system responds to noxious input. In states of altered processing, such as central or peripheral sensitization, the threshold tends to be lower, indicating hyperalgesia or allodynia. This approach directly targets sensory perception, unlike goniometry, which only gauges joint range of motion, MRI, which reveals structural anatomy, or EMG, which records muscle electrical activity. So, pressure algometry is the best method for assessing altered sensory processing.
