Objective:
Myofascial pain syndrome is a disorder characterized by hypersensitive sites called trigger points at one or more muscles and/or connective tissue, leading to pain, muscle spasm, sensitivity, rigor, weakness. The aim of this study was to explore the efficacy of lidocain and steroid in myofascial pain syndrome.
Material and Methods:
One hundred and sixty-four patients with myofascial pain syndrome were recruited into the study. Patients received lidocaine 2% (5ml)+NaCl 0.9% (5ml) onto the trigger points at first day. Lidocaine 2% (5ml)+triamsinolone 40mg (1ml)+NaCl 0.9% (4ml) were injected to the patients at fourth and eighth day. Pain was evaluated with visual analogue score (VAS), palpable muscle spasm scoring (PMSS) and number of trigger point at baseline, first and second month.
Results:
Pain control values with treatment were statistically better compared with pretreatment values. VAS scores, PMSS and number of trigger points significantly reduced 1 and 2 months after lidocaine and triamsinolone injection at the trigger point (p<0.01).
Conclusion:
The local anesthetic and steroid injection at the trigger point seems to be beneficial in myofascial pain syndrome. In conclusion, this therapy may be a alternative to other methods in the management of myofascial pain syndrome.
