Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
66 volunteers were treated with cervical pain, stimuation in trapezius muscles, by electroacupunture divided into 5 groups. Each group was treated with different frequencies stimulatory (2, 100, 1000, 2500 Hz and a group only with acupuncture). 66 volunteers received only one session by 20 minutes each. The electroacupuncture is a electrical
stimulation in the needles acupuncture. The eletroacupuncture was administred to the trapezius muscles in the acupoint denomination tianliao and jianjing.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Have been pre-selected volunteers with cervical tension in accordance with inclusion criteria. The Stimulatory frequency tested (2, 100, 1000, 2500 Hz) or only with acupuncture was choose by drawn randomly tested with numberes containers. The evaluation of clinical response (analgesia) was performed by an external evaluator.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Method of distribution of volunteers in the groups was distributed systematically by simple randomisation. There was a draw of groups (2, 100, 1000, 2500 Hz and only acupuncture) and its correlation with the numbers 1, 2, 3, 4 and 5. As the volunteers went to the treatment session take in a box drawn one of the numbers 1, 2, 3, 4 and 5. An external evaluator conducted the sweepstakes, and adjusted the stimulatory frequencies without the researcher knew which was being used at that time. The correspondence group with the results appeared only after the statistical treatment. Don't was selection of groups by age or gender.
