Which of the following techniques assists in joint mobilization?

Passive Range of Motion (PROM) is a technique that involves moving a joint through its full range of motion without the assistance of the patient. This technique is particularly beneficial in the context of joint mobilization because it helps maintain or improve joint function and mobility, especially after an injury or surgery. PROM can be performed by a physical therapist or assistant, using gentle movements to help reduce stiffness and increase circulation around the joint.

In the context of joint mobilization, PROM allows for the delivery of specific, controlled movements that can help restore normal joint mechanics. By repeatedly moving a joint through its available range, PROM can facilitate relaxation of the surrounding muscles and improve the overall joint extensibility, which is essential in rehabilitation processes.

Other options, although beneficial in their own right, do not directly assist in joint mobilization in the same manner as PROM. Cryotherapy focuses on reducing inflammation and pain rather than mobilizing the joint. Strength training aims to enhance muscle strength and stability, which can support joint function but does not directly mobilize the joint itself. Stretching exercises can improve flexibility of muscles and connective tissues but may not effectively address joint stiffness or mobilization on their own in the way that PROM does.
