B.J. Palmer the developer of Chiropractic explained it that simply. To help the boy – we must remove the interference to the current.
Subluxation begins the moment threat is perceived; this develops tension, joint fixation, dysafferentation is a cascade that occurs until improved inputs occurs.
Part of Subluxation is dural meningeal tension. Some consider this bracing. This occurs when the neurobiology/Central Nervous System perceives danger. When this occurs the dural meningeal system tightens or contracts with the fibroblast-to-myoblast conversion. This then creates neural guarding which is demonstrated through increased gamma motor gain. The result of this creates interference of the neural signal by reducing bandwidth. Ultimately compensates creating Subluxation.
