This study assesses the effects of dry needling with electrical stimulation to the low back on muscle activity and changes in movement. The investigators hypothesize that dry needling and electrical stimulation will elicit changes in muscle activity as well as changes in movement.
This study will utilize a Vicon motion capture system in conjunction with a Noraxon wireless surface electromyography system to analyze movements and muscle activity of each participant pre and post needling.

Paravertebral dry needling to L3, 4, 5 multifidi. Electrical stimulation will be applied through the needles for up to 10 minutes total or to the participant's tolerance.

Muscle activity changes
activity measured and quantified from the amplitude (mV) of the surface EMG electrodes
Time frame: pre/ post dry needling treatment. Participants' EMG will be recorded over a series of movements of the lumbar spine, will immediately be dry needled with electrical stimulation for up to 10 minutes, then will be immediately reassessed. Total time 2 hours
Kinematic changes
Measurement of lumbopelvic angles during range of motion activities
Time frame: Participants kinematics will be recorded over a series of movements of the lumbar spine, will immediately be dry needled with electrical stimulation for up to 10 minutes, then will be immediately reassessed. Total time 2 hours
