Summary

This study evaluates the effects of low level laser therapy and extracorporeal shock wave therapy in patients with myofascial pain syndrome of the upper trapezius. Half of the patients receive laser therapy, half of them receive shock wave therapy for three weeks.

Detailed description

Low Level Laser Therapy (LLLT) inducing photochemical and photothermal effect, increases blood flow and vascular permeability and improves cell metabolism. All these lead to muscle recovery. It also activates somatosensory receptors of the skin and reduces local pain and muscle spasm. The specific mechanisms of extracorporeal shock wave therapy (ESWT) in treating musculoskeletal pain remain unclear. It reduces pain and inflammation by modulating nitrogen-monoxide (NO) and vascular endothelial growth factor (VEGF). It can destroy sensory unmyelinated nerve fibers, and stimulate neovascularization and collagen synthesis in degenerative tissues.

Conditions

• Myofascial Pain Syndrome

Interventions

Type	Name	Description
DEVICE	Extracorporeal Shock Wave Therapy	shock wave therapy once a week for three weeks, total of 1000 shock waves for each treatment at the frequency of 10Hz, with 2 Bar pressure and energy flux density (EFD) of 0.25 mJ/mm2 per minute using a BTL-6000 SWT Topline Power® device
DEVICE	Low Level Laser Therapy	LLLT once a day for three weeks (altogether 15 working days) using a PR999 4W scanning laser device; around trigger points with 3 J/cm2, power 800 mW, frequency 2000Hz, on trigger points with 9 J/cm², power 2000mW, frequency 5000Hz for total of 2 minutes on each spot
