Effects of Extracorporeal Shock Wave Therapy and Low Level Laser Therapy in Myofascial Pain Syndrome
Comparative Study of Shock Wave Therapy and Low Level Laser Therapy Effect in Patients With Myofascial Pain Syndrome of the Trapezius
Study Overview

Conditions
Intervention / Treatment
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.

Active Comparator: Extracorporeal shock wave therapy group
Patients in the shock wave therapy group received 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 by using BTL-6000 SWT Topline Power® 3 times with a week's interval between the treatments.
|
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
|
Active Comparator: Low Level Laser Therapy group
Patients in the laser therapy group received LLLT once a day for three weeks (altogether 15 working days) to the trigger points and around them in the upper trapezius.
The type of laser used: PR999 4 Watt (W) scanning laser; Medical Italia®, around trigger points with 3 Joule /centimeter² (J/cm²), power 800 milliwatt (mW), frequency 2000 Hertz (Hz), on trigger points with 9 J/cm², power 2000mW, frequency 5000Hz for total of 2 minutes on each spot.

Measure Description |
Time Frame |
---|---|---|
change in severity of pain at rest
Time Frame: week 0 and week
|
change from baseline severity of pain at rest recorded on a 100 mm visual analogue scale, where 0 mm represents no pain, 100 mm represents unbearable pain.
|
week 0 and week
|
change in severity of pain at rest
Time Frame: week 0 and week 15
|
change from baseline severity of pain at rest recorded on a 100 mm visual analogue scale, where 0 mm represents no pain, 100 mm represents unbearable pain.
|
week 0 and week 15
|
change in severity of pressure pain
Time Frame: week 0 and week 3
|
change from baseline severity of pressure pain recorded on a 100 mm visual analogue scale, where 0 mm represents no pain, 100 mm represents unbearable pain.
|
week 0 and week 3
|
change in severity of pressure pain
Time Frame: week 0 and week 15
|
change from baseline severity of pressure pain recorded on a 100 mm visual analogue scale, where 0 mm represents no pain, 100 mm represents unbearable pain.
|
week 0 and week 15
|
change in function (percentage of disability)
Time Frame: week 0 and week 3
|
change from baseline Neck Disability Index (NDI) at week 3.
It includes 10 part; pain intensity, personal care, lifting objects, reading, headache, concentration, work, driving, sleeping and entertainments.
There are six presumptions; the first is given 0 and the last presumption has the score of 5.
The total maximum score is 50, that represents 100% disability.
The lower score represents better outcome.
|
week 0 and week 3
|
change in function (percentage of disability)
Time Frame: week 0 and week 15
|
change from baseline Neck Disability Index (NDI) at week 15.
It includes 10 part; pain intensity, personal care, lifting objects, reading, headache, concentration, work, driving, sleeping and entertainments.
There are six presumptions; the first is given 0 and the last presumption has the score of 5.
The total maximum score is 50, that represents 100% disability.
The lower score represents better outcome.
|
week 0 and week 15
|
change in quality of life
Time Frame: week 0 and week 3
|
change from baseline quality of life (36-Item Short Form Health Survey /SF-36/) at week 3.
It consists of eight scaled scores (vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, mental health), which are the weighted sums of the questions in their section.
Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight.
The lower the score the more the disability, i.e. a score of zero is equivalent to maximum disability.

Time Frame: week 0 and week 15
|
change from baseline quality of life (SF-36) at week 15.
It consists of eight scaled scores (vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, mental health), which are the weighted sums of the questions in their section.
Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight.
