• Status: Not yet recruiting
• Trial end date: 2022-12-31
• Target enrollment: 0
• Participant gender: All

Summary

Patients with an myofascial trigger point (MTrP) in their upper trapezius will be divided into three groups: Group A receiving MTrP injection with normal saline (control group), Group B with hypo-osmolar dextrose (5% dextrose), and Group C with hyper-osmolar dextrose (15% dextrose). Clinical outcomes and morphological changes will be measured before the injection, one hour after, one week after, two weeks after, and one month after the injection to delineate the therapeutic effects of dextrose injection for an MTrP.
