What is PF-ROM (passive-forced) used for?

PF-ROM, or passive-forced range of motion, is primarily utilized to test the end-feel of a joint. This technique involves the therapist actively moving the patient's joint through its range of motion while providing a gentle force at the end of that motion. By doing so, the therapist can assess the quality of resistance encountered at the endpoint of the joint movement, which helps in determining the structure and integrity of the joint, including whether it is normal, soft, firm, or hard.

Evaluating the end-feel is crucial in clinical assessments as it helps differentiate between different types of joint conditions. For example, a soft end-feel might indicate edema or tissue swelling, while a hard end-feel could suggest bony block or stiffness due to joint degeneration. Understanding the end-feel is also an essential part of formulating an effective treatment plan, helping practitioners decide whether to pursue mobility work, strengthening exercises, or other interventions.

The other choices relate to different functions that are not directly associated with PF-ROM. For example, assessing range limitation could involve measuring how far a joint can move actively or passively but does not specifically involve the examination of the end-feel itself. Evaluating joint stability typically involves dynamic assessments or special tests rather than passive evaluation
