ABSTRACT
Introduction:
The primary objectives of treating fibromyalgia syndrome (FMS), which frequently coexists with myofascial pain syndrome (MPS), are to deactivate trigger points, alleviate pain, and remove factors that exacerbate the condition. Recently, the use of ultrasound (US) has been advocated to reduce potential complications during trigger point injections (TPI) and to ensure a more
effective treatment administration. This study aimed to compare the effectiveness of blinded versus US-guided TPI into the trapezius muscle in patients with FMS and associated MPS.
Methods:
A total of 75 patients with FMS and trapezius muscle trigger points indicative of MPS participated in this study. They were randomly assigned to one of two groups: the US-guided trigger point group and the blinded trigger point group. Both groups followed the same home exercise regimen, which included stretching and posture exercises targeting the trapezius and pectoral muscles.
The effectiveness of the treatments was evaluated one month after treatment. The assessment tools included the Fibromyalgia Impact Questionnaire for function, the visual analog scale for pain, the Beck Anxiety Inventory for anxiety, and the Neck Disability Questionnaire for neck disability.
Results:
Data from 60 patients were included in the final analysis. No statistically significant differences were found between the demographic variables of the two groups (p>0.05). A comparison of US-guided and blinded TPI revealed a significant difference in neck disability (p=0.041). Both groups showed significant improvements in all evaluated parameters from pre-treatment to posttreatment (p<0.05).
Conclusion:
US-guided TPI positively impacted pain, function, anxiety, and neck pain in patients with FMS and associated MPS. This method can be recommended in clinical settings to help alleviate the symptoms of both conditions.
