Comparing Lidocaine Alone and Lidocaine Plus Magnesium Sulfate for Treating Myofascial Pain Dysfunction Syndrome Using Muscle Activity and Pain Measures

What this Trial Is About

This clinical trial investigates the treatment of Myofascial Pain Dysfunction Syndrome MPDS, a condition involving painful muscle trigger points. Researchers aim to compare the effects of two types of trigger point injections lidocaine alone versus lidocaine combined with magnesium sulfate. The goal is to determine if adding magnesium sulfate improves pain relief and muscle relaxation in patients with MPDS. Participants will be randomly assigned to one of two groups. One group will receive injections of 2% preservative-free lidocaine alone, while the other group will receive injections combining 2% lidocaine with 10% magnesium sulfate. The injections will be given into the most painful trigger points using a specific technique called Fast-in, fast out or peppering. The study will assess pain levels using the Visual Analog Scale VAS and muscle activity through surface electromyography sEMG at baseline, 1 week, and 2 weeks after injection. Throughout the study, participants will be evaluated for pain reduction and muscle function improvement at multiple time points. Pain during and after injections will also be measured. The study involves visits for injections and follow-up assessments to monitor changes in pain and muscle activity. This research may help improve treatment strategies for MPDS by providing evidence on the use of magnesium sulfate as an add-on to lidocaine injections.
