About

This study aims to compare the effectiveness of blinded versus ultrasound-guided trigger point injections into the trapezius muscle in patients with FMS. Seventy-five patients with FMS will participate in this study. They will be randomly assigned to one of two groups: one group received ultrasound-guided trigger point injections, while the other group received blinded trigger point injections. Both groups will follow 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 post-treatment. The assessment tools will include the Fibromyalgia Impact Questionnaire (FIQ) for function, the Visual Analog Scale (VAS) for pain, the Beck Anxiety Inventory (Beck-A) for anxiety, and the Neck Disability Questionnaire (NDQ) for neck disability.

Full description

The primary objectives in treating Fibromyalgia Syndrome (FMS) 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 and to ensure more effective administration of the treatment.This study aims to compare the effectiveness of blinded versus ultrasound-guided trigger point injections into the trapezius muscle in patients with FMS. Seventy-five patients with FMS will participate in this study. They will be randomly assigned to one of two groups: one group received ultrasound-guided trigger point injections, while the other group received blinded trigger point injections.

20 participants in 2 patient groups

Ultrasound-guided injection

Experimental group

Description:

The skin will be cleaned with a suitable antiseptic solution and a sterile, 25 G, 1.5 inch dental-tipped needle will be used. Patients will be injected with 5 ml 2% lidocaine + 5 ml 0.9% NaCl. The linear probe (PLT-704SBT, 7.5 MHz) of the ultrasound device will be kept parallel to the trapezoidal fibers on the marked trigger point and the dental-tipped needle will be directed to the targeted point in plane with real-time imaging

Treatment:

Other: Ultrasound guided injection

Blinded injection

Experimental group

Description:

The skin will be cleaned with a suitable antiseptic solution and a sterile, 25 G, 1.5 inch dental-tipped needle will be used. Patients will be injected with 5 ml 2% lidocaine + 5 ml 0.9% NaCl. The needle will be directed to the most sensitive point and advanced until it will be reached the trigger point.

Treatment:

Other: Blinded injection
