Joint mobilization and manipulation are passive techniques used by physiotherapists to increase range of motion (ROM) and decrease pain in joints. Mobilization involves small, rhythmic movements within a joint's available ROM, while manipulation is a sudden, forceful thrust beyond a patient's control. Both techniques work to move synovial fluid, maintain joint tissue extensibility, provide sensory input, and stimulate mechanoreceptors to reduce pain. Precautions are taken with patients having conditions like hypermobility, inflammation, or bone fractures.
