SPRING TEST
(PA Glide Test)
• Test positioning
The client lies prone and the therapist stands with the thumb or hypothenar eminence (specifically the pisiform) over the spinous process of a lumbar vertebra.
• Action
Apply a downward "springing" force through the spinous process of each vertebra to assess posterior-anterior motion.
This action should be repeated for each transverse process to assess rotary motion.
• Positive finding
Increases or decreases in motion at one vertebra compared to another are indicative of hypermobility or hypomobility, respectively.
• Special considerations & comments
Rotational accessory movement can be compared at each level by performing this test to the transverse process on each side of one vertebral level.
The Spring Test, also known as the PA Glide Test, is based on the work of Dr. James Cyriax in assessing joint mechanics and segmental mobility in the lumbar spine, with further contributions from Dr. John Mennell in manual therapy techniques.
