Purpose of the Study:
- To investigate the efficacy of topical lidocaine 5% patches for myofascial pain.
- To assess the impact of lidocaine patch therapy on patients' quality of life.
Main Methods:
- An open-label, one-month trial involving 27 patients with moderate-severe myofascial pain.
- Utilized Brief Pain Inventory-Short Form to measure pain intensity and quality of life changes.
- Included patients with low back pain as a significant subgroup.
Main Results:
- Significant improvements observed in average pain intensity, general activity, mood, and sleep.
- Improvements in walking ability and capacity for work, relationships, and life enjoyment were noted.
- Two patients reported complete pain relief, and three reported substantial relief.
Conclusions:
- Topical lidocaine 5% patches may offer a beneficial treatment option for myofascial pain.
