Outcome Measures

Primary Outcomes (1)

  • Neck Disability Index - NDI

    Recruitment will be determined from the results of the application of the NDI, which is composed of 10 questions addressing general activities and pain. The items are organized by the type of activity and involve six response options expressing progressive degrees of functional disability. Patients who had a score above 10% on the ndi questionnaire answers will be interviewed with the following questions: do you feel any pain often?, have had torticollis? how many times? and as to the time of pain. Those who answer that has intermittent pain for 3 months or more will be selected.

    One Year

Secondary Outcomes (8)

  • Surface electromyography (EMG) of neck extensors

    baseline and 6 weeks

  • Analysis of salivary cortisol

    baseline and 6 weeks

  • Neck extensor endurance test

    baseline and 90 days

  • Evaluation of cervical range of motion

    baseline and 90 days

  • Postural evaluation

    baseline and 90 days

  • +3 more secondary outcomes

Study Arms (2)

Group B & Group C

EXPERIMENTAL

Group B equal to low-level laser therapy dosis 5,9 j per point Group C equal to Placebo group

Other: LaserOther: Placebo

Group A & Group C

NO INTERVENTION

Group A equal to Control (no intervention) Group C equal to Placebo group

Interventions

LaserOTHER

The laser will be used 830 nm, 30 milliwatts twice a week: the initial dosage will be 5.9 J per point. The irradiation will be performed bilaterally on the belly of the trapezius muscle as well as 2 cm to the right and left and 2 and 4 cm below the belly of the muscle.

Group B & Group C
PlaceboOTHER

To provide the "blinding": the laser equipment has two identical application points furnished by the manufacturer - one active and the other a placebo (does not emit energy).

Group B & Group C
