Overview
Brief Summary
To characterize muscle activity through electromyography (EMG) of the lumbar spine during high velocity, low amplitude (HVLA) spinal manipulation according to parameters of practitioner contact (location, applied force) in healthy participants and two categories of low back pain participants.

Outcomes
Primary Outcomes
Muscle Response
Time Frame: During spinal manipulation at the time of testing
Muscle activity of the lumbar spinal musculature as measured by both surface and indwelling electromyography. Total response expressed as a percentage of muscles "on".
Muscle Activity Onset Delay
Time Frame: During spinal manipulation at the time of testing
Muscle activity of the lumbar spinal musculature as measured by both surface and indwelling electromyography. Time delay between the manipulation force and the muscle activity
