The Effect of Combined Neuromuscular Electrical Stimulation and Motor Control Training on Lumbar Multifidus Muscle Activation in Individuals With Impaired Lumbopelvic Control
In Brief
A clinical study evaluating Combined NMES and motor control and Motor control and placebo NMES for Instability; Back. Completed, enrolled 50 participants across 1 site.
Detailed Summary
Phase I, this study aims to:- 1. Establish intra- and inter-rater reliability and minimal detectable change of ultrasound imaging measurement 2. Determine appropriate mode and dose for neuromuscular electrical stimulation on lumbar multifidus muscle 3. Determine feasibility of proposed protocol and physical therapy intervention Phase II, this study aims to:- 1. Determine the difference lumbar multifidus muscle activation based on arthrogenic muscle inhibition model between individuals with and without impaired lumbopelvic control 2. Determine the effect of combined neuromuscular electrical stimulation and motor control training in individual with impaired lumbopelvic control
Study Details
Timeline
Interventions
This group will receive the neuromuscular electrical stimulation using interferential mode (6000 Hz, beat frequency 20-50 Hz, scanning effect) on bilateral lumbar multifidus muscles. The intensity will be set at the subject's maximum tolerance. Stimulation will be set at 10 seconds on and 60 seconds off to minimize muscle fatigue. The total stimulation time is 15 minutes. After that, this group will receive 30 minutes motor control training. This motor control training will focus on the control of the lumbar multifidus muscle in various functional tasks. It is believed to restore the motor units in individuals with arthrogenic muscle inhibition. This motor control training will take approximately 30 minutes. This group will receive intervention twice a week for 8 weeks.
