Mechanical-Assisted Spinal Manipulation Thrust Profiles. The thrust profiles of mechanical-assisted spinal manipulation using the Activator IV instrumented device for the 3 muscle spindle afferents in this study are shown. Total peak force includes preload which can be influenced by the device operator.

Afferent Number Device Setting Thrust Duration (ms) Preload Force (N) Total Peak Force (N)
1 1 2.0 9.1 116.5
2 1 3.0 6.7 121.8
2 2 2.1 9.7 115.9
3 1 3.0 6.5 106.6
3 1 3.0 4.5 111.2
3 1 3.0 5.7 110.3
3 1 3.0 7.5 107.9
3 2 3.0 10.8 83.9
3 2 3.0 4.9 78.2
