Establishing force and speed training targets for lumbar spine high-velocity, low-amplitude chiropractic adjustments.

ABSTRACT:

Objective

We developed an adjusting bench with a force plate supporting the lumbar portion to measure loads transmitted during lumbar manual adjustment. It will be used to provide force-feedback to enhance student learning in technique labs. The study goal is to define the learning target loads and speeds, with instructors as expert models.

Methods

A total of 11 faculty members experienced in teaching Gonstead technique methods performed 81 simulated adjustments on a mannequin on the force plate. Adjustments were along 9 lumbopelvic "listings" at 3 load levels: light, normal, and heavy. We analyzed the thrusts to find preload, peak load, duration, and thrust rate.

Results

Analysis of 891 thrusts showed wide variations between doctors. Peak loads ranged from 100 to 140
