A double-blind, placebo-controlled, random
allocation study. 41 subjects, chronic myofascial trigger points
in the neck and upper trunk region, five treatment sessions over
a two week period, All groups demonstrated significant reductions
in pain over the duration of the study.

Double-blind, pulsed infrared, treatment of
myofascial pain in the cervical region. 27 subjects, 12 LLLT sessions,
alternate days, at each session the four most painful muscular
trigger points and five bilateral homometameric acupuncture points
were irradiated with 1J. Pain was monitored using McGill pain
questionnaire andScottHuskisson visual analogue scale, pain attenuation
in the treated group and a statistically significant difference
between the two groups of patients, both at end of therapy and
at the 3-month follow-up examination.

3: Vaxholm Health Care Centre, Stockholm, Sweden.
A double-blind study, laser therapy for tendinitis
and myofascial pain,176 subjects, 6 treatments during a period
of 3-4 weeks.Pain estimated objectively using a pain threshold
meter, and subjectively with a visual analogue scale. Laser therapy
had a significant, positive effect compared with placebo. Laser
treatment was most effective on acute tendinitis.
