Brief summary
Low level laser treatments have been used to treat painful trigger points in myofascial pain syndrome (MPS), but the effectiveness of the appropriate laser type and parameters is still uncertain. The aim of this study was to compare the effectiveness of different types of low level laser treatment (LLLT) in reducing pain levels, changing oxygen saturation and bite force in patients with MPS.
Detailed description
A total of 45 patients with MPS were randomly divided into three groups. First group received LLLT with GRR laser over massater muscle region. Patients in the second group were treated with Nd:YAG laser and the same protocol with Nd:YAG laser was performed in the placebo group using sham device. Pain was evaluated by visual analogue scale (VAS), change in oxygen concentration in the massater muscle was measured by functional near-infrared spectroscopy- fNIRS and bite force was measured with Flexiforce sensors before and after treatment.
Interventions
DEVICEGRR laser
A total of 15 sessions were applied to each patient for three weeks, five times per week.
DEVICENd:YAG laser
A total of 10 sessions, five sessions per week, were applied

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| change from baseline in pain on the 10 point visual analogue scale (VAS) at week 3 | baseline and week 3 | Patients were asked to rate the intensity of their pain on a scale from 0 to 10. They were told that a score of 0 meant no pain, a score of 10 meant severe pain and a score of 5 meant moderate pain |
| change from baseline in oxygen concentration in the massater muscle at week 3 | baseline and week 3 | oxygen concentration in the massater muscle was measured by functional near-infrared spectroscopy- fNIRS (ARGES cerebro, Hemosoft Inc., Ankara, Turkey) before and after treatment for each patient. |
| change from baseline in bite force values at week 3 | baseline and week 3 | bite force values were recorded by Flexiforce sensors before and after treatment for each patient. |
