EMG-Triggered Electrical Stimulation for Trunk Balance in Spinal Cord Injury

This study is focused on helping people with complete spinal cord injuries, specifically at the thoracic level, improve their ability to sit and perform daily activities without assistance. Such injuries often lead to weakened muscles in the back, known as paraspinal muscles, which are essential for maintaining balance in the trunk. The study explores the use of a technique called electromyography (EMG) triggered electrical stimulation on two key back muscles—the multifidus and erector spinae—to enhance trunk balance and muscle strength. This research is important because it could lead to better rehabilitation methods, improving the quality of life for those affected by this condition. Participants in this study will receive electrical stimulation treatments targeted at their back muscles. The procedure involves using EMG, which detects muscle activity, to trigger electrical stimulation that helps strengthen these muscles. The study will measure how well this treatment improves the participants' ability to maintain balance while sitting. By monitoring changes in muscle thickness and balance, researchers aim to evaluate the effectiveness of this approach. The goal is to see if this method can offer a safe and beneficial way to support muscle function in individuals with spinal cord injuries.
