What defines the paraphysiological space?

The paraphysiological space is defined as the area that exists between the anatomical barrier of a joint and the onset of pain. This space represents a range of motion that exceeds the normal passive range but is still within a zone where the structures of the joint can be manipulated without causing pain. It is significant in clinical settings, especially in rehabilitation and manual therapy, as it allows practitioners to explore additional joint mobility while remaining mindful of the patient's comfort and safety. Understanding this space helps clinicians to apply techniques effectively and recognize the limits of joint movement during treatment.

The other options do not accurately capture the concept of the paraphysiological space. Instead, they refer to other aspects of joint mechanics or movement that do not encompass the defined area of interest pertinent to this term.
