Ceiling effect in prognosis refers to which concept?

• A. The maximum achievable recovery due to interdependent factors
• B. The floor effect
• C. A plateau in progress without limit
• D. No relation to prognosis

Answer: (A)

The ceiling effect in prognosis means there is an upper limit to how much recovery is realistically achievable, set by interdependent biological and functional factors. In rehabilitation, outcomes are measured on scales, and when a patient approaches the top end or when factors such as age, comorbidities, and neural recovery potential cap further gains, progress appears to stall at that ceiling. This limits how much prognosis can anticipate improvement, because you’ve hit a upper boundary. It’s different from a floor effect, which is about the lower limit of detectable change, and not from a plateau described as having no limit—real limits do exist. Being aware of a ceiling helps clinicians set realistic goals and interpret prognosis accordingly.
