Actual (reported)Change from Baseline in Pressure pain threshold at 10 minutes after the intervention
To obtain the pressure pain threshold measurements, an electronic pressure algometer was used. With the subject seated, the evaluator placed the pointer on the trigger pint with an approximate angle of 90º and an increasing pressure of approximately 1 kg/cm²/s. Subjects were told to use the word "now" whenever the sensation of pressure was replaced by a sensation of pain. At this point, the evaluator removed the algometer and the equipment recorded the maximum applied pressure.

In each volunteer, the therapist identified the latent trigger point on the upper trapezius. A questionnaire about general information was performed. And the maximum homolateral side flexion of the trigger point was measured. On the following week, the blind assessor performed the pre-intervention measurements of pressure pain threshold, pressure pain perception and cervical range of motions. Next, the therapist performed the muscle energy technique of the upper trapezius muscle. Then, all measurements, before described, were repeated, by the assessor, after 10 minutes, 24 hours and one week.

Then, all measurements, before described, were repeated, by the assessor, after 10 minutes, 24 hours and one week.
The therapist, with one hand on the occipital bone and the other on the shoulder, performed passive side flexion, contralateral to the muscle, taking the subject's head until the end-feel. Then, subjects performed an isometric contraction of 25% of their maximum force, for 5 seconds, while the therapist offered manual resistance. Afterwards the subject was let to relax in this position for additional 5 seconds. Side flexion was now increased until a new end-feel point was reached. This sequence was repeated 3 times. At the end, the therapist passively guided the cervical segment to the neutral position.

The Effect of Soft Tissue Mobilization in Myofascial Neck Pain
To obtain the pressure pain threshold measurements, an electronic pressure algometer was used. With the subject seated, the evaluator placed the pointer on the trigger pint with an approximate angle of 90º and an increasing pressure of approximately 1 kg/cm²/s. Subjects were told to use the word "now" whenever the sensation of pressure was replaced by a sensation of pain. At this point, the evaluator removed the algometer and the equipment recorded the maximum applied pressure.
one week after the intervention
In each volunteer, the therapist identified the latent trigger point on the upper trapezius. A questionnaire about general information was performed. And the maximum homolateral side flexion of the trigger point was measured. On the following week, the blind assessor performed the pre-intervention measurements of pressure pain threshold, pressure pain perception and cervical range of motions. Next, the therapist performed the passive stretching of the upper trapezius muscle. Then, all measurements, before described, were repeated, by the assessor, after 10 minutes, 24 hours and one week.

And the maximum homolateral side flexion of the trigger point was measured. On the following week, the blind assessor performed the pre-intervention measurements of pressure pain threshold, pressure pain perception and cervical range of motions. Next, for the sham technique, the therapist only contacted with his hands the head and the shoulder of the subject, without executing any movement, for 30 seconds. Then, all measurements, before described, were repeated, by the assessor, after 10 minutes, 24 hours and one week.

And the maximum homolateral side flexion of the trigger point was measured. On the following week, the blind assessor performed the pre-intervention measurements of pressure pain threshold, pressure pain perception and cervical range of motions. Next,the subject was lying for 30 seconds, without intervention. Then, all measurements, before described, were repeated, by the assessor, after 10 minutes, 24 hours and one week.
The therapist, with one hand on the occipital bone and the other on the shoulder, performed a contralateral side flexion of the muscle passively until the maximum obtainable amplitude was reached, while subjects were asked to breathe steadily. During the breathing phase the therapist increased the side flexion until the end of the obtainable amplitude, this position was maintained. This procedure was repeated during 30 seconds. Finally the therapist passively guided the cervical segment to the neutral position.
The therapist, with a pincer contact, applied gradual pressure on the latent trigger point of the upper trapezius muscle. Subjects had been previously asked to say when pain was "moderate but bearable", a pain value of 7 in a 1 to 1o scale of pain (in which 1 corresponds to "no pain" and 10 do "unbearable pain"). At this point, pressure was maintained until pain levels were reduced to level 3. The therapist increased once more the pressure until the level of pain was 7 again. This procedure was repeated during 90 seconds.
The therapist was seated at the head of the treatment table, and with one hand on the occipital bone and the other on the shoulder, without executing any movement, for 30 seconds.
