Passive Accessory Intervertebral Movements


Go to the video

Passive accessory intervertebral movements (PAIVM): Patient lies prone and the therapist tests intervertebral motion. The therapist places the hypothenar on the spinous process and moves the spinous process in an anterior-posterior motion. Each segment’s mobility is judged as normal, hypermobile or hypomobile, noting the presence of pain during the movement. Alqarni et al. (2011) suggest a standardization of the test to increase reliability.

Reported to have low sensitivity; 29% (Abbott et al. 2005), to 46% (Fritz et al. 2005), but a high specificity of 81% (Fritz et al. 2005) to 89% (Abbott et al. 2005).
