An area of somatic dysfunction that is responsible for and maintains a total pattern of dysfunction is the

• A. Primary dysfunction
• B. Secondary dysfunction
• C. Tertiary dysfunction
• D. Central dysfunction

Answer: (A)

The concept here is identifying the initiating site of somatic dysfunction that drives the whole pattern. In osteopathic thinking, a total pattern of dysfunction is built around a primary dysfunction—the initial area where tissue texture changes and motion restriction originate. This primary lesion sets off a cascade of compensatory changes in other regions, creating secondary and tertiary dysfunctions that together make up the full pattern. Because the primary dysfunction is driving and sustaining the entire pattern, addressing it is key to resolving the whole sequence. Secondary dysfunction refers to changes in other areas that arise in response to the primary dysfunction, not the starting point itself. Tertiary dysfunction describes additional compensations that develop over time as the pattern persists. Central dysfunction isn’t a standard term used to describe the initiating driver in this framework, so it doesn’t capture the same concept as the primary dysfunction.
