The Mulligan technique involves applying sustained pressure or mobilization to a joint while the patient performs a specific movement. The goal is to restore normal joint mechanics and reduce pain and dysfunction. Key techniques include SNAGs (sustained natural apophyseal glides) and SMWLMs (spinal mobilization with limb movement). The technique follows the principle that once a passive glide is pain-free, the physiotherapist progresses the treatment by having the patient perform movements without pain. Contraindications include fractures, dislocations, ligament/tendon tears, joint instability, and acute inflammation.
