This document discusses the concept of mobilization with movement (MWM), as developed by Brian Mulligan. MWM involves applying a sustained accessory mobilization by the therapist while the patient performs an active movement. It is based on the idea that minor positional faults in joints can cause pain and limited range of motion, and that correcting these faults through MWM can provide fast pain relief and improved function. Specific MWM techniques discussed for the spine include natural apophyseal glides, reverse natural apophyseal glides, and sustained natural apophyseal glides, while movement with mobilizations is described as the extremity technique. The principles, indications, contraindications and applications of MWM are outlined.
