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.

1: Akersberga Health Care Centre, 2: Danderyd University Hospital, Danderyd, and

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.
