Muscle Activity and Kinematic Changes With Dry Needling

Not Applicable

Completed

• Conditions: Healthy
• Interventions: Other: Dry needling with electrical stimulation

• Registration Number: NCT04295200
• Lead Sponsor: Louisiana State University Health Sciences Center Shreveport

Brief Summary

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.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
Dry needling with electrical stimulation	Dry needling with electrical stimulation	Use of dry needles (this is the generic name for sterile, solid filament needles) are inserted into the lumbar multifidi. Intramuscular electrical stimulation will then be applied by attaching a six-lead electrical stimulation unit to the needles. Electrical stimulation will be applied through the needles at the participant's desired frequency (between 4-6 Hz) and for up to 10 minutes total.

Primary Outcome Measures

Name	Time	Method
Muscle activity changes	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	activity measured and quantified from the amplitude (mV) of the surface EMG electrodes
Kinematic changes	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	Measurement of lumbopelvic angles during range of motion activities
