Summary

Myofascial pain syndrome (MPS) is one of the most common causes of musculoskeletal pain. Among patients with MPS, the upper trapezius muscle appears to be the common muscle that generates pain in the area of upper extremity. The main target treatment for MPS is to eradicate the painful trigger points by using treatment options, such as ultrasound, laser, and dry needling (DN). In the past decade, focused extracorporeal shockwave therapy (fESWT) has become the well-known treatment for pain relief in various musculoskeletal pain conditions. The main advantages of this non-invasive treatment modality are reducing pain, inflammation and promoting tissue healing. However, there were no previous studies compared effects of fESWT to dry needling. Therefore, the present study aims to compare the efficacy of the two treatments in terms of pain reduction and functional improvement.

Detailed description

* This study is a single-blinded non-inferiority randomized controlled trial that will compare the efficacy of fESWT to DN in terms of pain reduction and functional improvement in patients with MPS of the upper trapezius. * 58 patients will be recruited for the study and randomly allocated to 2 groups, mainly fESWT and DN. * For the fESWT group, the participants will receive fESWT once a week, for a total of 3 sessions, consecutively. While the participants in the DN group will receive DN at the painful trigger point for 1 session. Moreover, both groups will receive the same conservative treatment, for example, education, exercise, and behavioral modification advice. * The primary outcome is Visual Analogue Scale (VAS) and the secondary outcomes are Pain Pressure Threshold (PPT) and Neck Disability Index (NDI) which will be recorded at baseline, 1 week, 3 week, and 6 week from baseline. * Statistical analysis will be performed using Stata to detect statistically significant changes in the same group and differences between the two groups.

Conditions

• Myofascial Pain Syndrome

Interventions

Type	Name	Description
DEVICE	Focused Extracorporeal Shockwave Therapy (fESWT)	fESWT will be done using an energy flux density of 0.20 - 0.25 millijoule (mJ)/mm2, a frequency of 4 Hz, and 1000 shocks per session which will be done one session per week, for a total of 3 sessions, consecutively.
OTHER	Dry needling (DN)	DN will be done by using a sterile technique with a sterile acupuncture needle, a diameter of 0.25 mm, and a length of 30-40 mm. The needle will be applied to the painful active trigger point using fan-shaped movements and the fast-in and fast-out technique until the twitching response disappears.
