What does passive range of motion involve?

Passive range of motion involves movement that is performed by an external force, such as a therapist or a device, without any effort from the patient. This technique allows the practitioner to assess the range of motion of a joint and evaluate the flexibility of the muscles and connective tissues surrounding it. In passive range of motion exercises, the patient does not actively participate; rather, they remain relaxed while the external force moves their limb through its available motion.

This method can be useful in rehabilitation settings, where patients may not yet be able to perform active movement due to injury or weakness. By evaluating passive range of motion, healthcare professionals can identify limitations, pain, or any restrictions that may be present within the joint or surrounding structures.
