Magnesium-Based Trigger Point Infiltrations Versus Local Anaesthetic Infiltrations in Chronic Pelvic Myofascial Pain:...

Area of Science:

• Gynecology
• Pain Management
• Pharmacology

Background:

• Chronic myofascial pelvic pain is a debilitating condition often associated with myofascial trigger points.
• Current treatment options for chronic pelvic pain can be limited, necessitating research into novel therapeutic approaches.

Purpose of the Study:

• To compare the efficacy of a novel magnesium-based trigger point infiltration formulation against lidocaine-only infiltration for treating chronic myofascial pelvic pain.
• To evaluate improvements in pain scores, pain with function, and quality of life.

Main Methods:

• A single-center, double-blind, randomized controlled trial was conducted with women diagnosed with chronic myofascial pelvic pain.
• Participants received either magnesium-based infiltration, lidocaine infiltration, or were waitlisted for a chronic pain clinic.
• The study involved 8 trigger point injection treatments over a 12-week period, with regular pain score assessments.

Main Results:

• Both magnesium-based and lidocaine infiltration groups showed a clinically relevant decrease in mean pain scores compared to the waitlist group.
• The magnesium-based group demonstrated a statistically significant improvement in pain scores compared to the waitlist group (P=0.045).
• Improvements in pain with function and quality of life scores were observed in both treatment groups.

Conclusions:

• The study, although underpowered, did not find the magnesium-based infiltrate to be more effective than lidocaine-only infiltration for chronic myofascial pelvic pain.
• Both magnesium-based and lidocaine infiltrations appear to improve pain, pain with function, and quality of life in patients with chronic myofascial pelvic pain.
• The findings support current management recommendations and suggest a potential treatment approach for general gynecologists.
