Final answer:
The Go-scope or nervoscope is used in the (B) Gonstead technique to detect spinal subluxations by measuring heat variations along the spine.
Step-by-step explanation:
The Go-scope or nervoscope is a device that is commonly used to detect the level of subluxation in the Gonstead chiropractic technique. The Gonstead technique is a method of chiropractic care that involves thorough analysis to detect spinal misalignments, known as subluxations, which can affect nervous system function and overall health.
Uneven heat distributions along the spine can be a sign of nerve pressure and inflammation, as detected by the nervoscope. It is a particular tool used in the Gonstead method; it is not commonly utilized in Activator, Network, or NUCCA chiropractic procedures.
