Muscle Activation Characteristics During Spinal Manipulation in Healthy and Low Back Pain Participants

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.

Treatment and study plan

Spinal manipulation

Procedure

HVLA (High Velocity Low Amplitude) spinal manipulation directed at the lumbar spine and sacroiliac (SI) joints

Primary outcomes

  1. 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".

  2. 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
