Electric boost for back pain? trial tests stimulation plus exercise

This trial tests whether adding a special electrical stimulation treatment to a standard core exercise program can reduce pain and improve function in adults with chronic low back pain. Forty-five people will be split into three groups: one gets core exercises plus a lumbar strengthening stimulation program, another gets core exercises plus a muscle relaxation stimulation program, and the third does core exercises alone. Treatment lasts six weeks, with sessions twice a week. The main goal is to see if pain intensity changes, and the study also looks at disability, daily function, quality of life, and sleep.
