Sweet relief? sugar injections tested for stubborn shoulder pain

This study tested whether injections of a sugar-water solution (dextrose prolotherapy) could reduce pain and improve function in people with long-term rotator cuff shoulder problems. 60 patients who hadn't gotten better with standard treatments were randomly assigned to receive either the dextrose injections or placebo saline injections, along with a home exercise program. Researchers measured changes in pain levels, shoulder function, and mobility over three months to see if the dextrose treatment worked better.
