About this study
Official title: EFFECTS OF SHOCK WAVE THERAPY IN MIOFASCIAL PAIN: RANDOMIZED AND BLIND CLINICAL TEST
The study consisted of 60 women who had pain-point pains in the upper fibers of the trapezius muscle. They had a medical age of 22.8 years, with a body mass index of 22.8 kg / cm2.They underwent an initial assessment, with a visual analogue pain scale, followed by an assessment of pain threshold, and manual muscle strength.Then, they were allocated into three groups: control group with 20 volunteers without intervention, placebo group with 20 volunteers with shock wave simulation and an intervention group with 20 volunteers with shock wave therapy.
All volunteers were evaluated immediately after the protocol (post evaluation) and 48 hours after the intervention protocol (48 hour evaluation). A mixed ANOVA of repeated measurements was used for intra and intergroup comparisons, followed by tukey post hoc. Significance was set at 5% (p <0.05).
Read the detailed description
The objective was to investigate the effects of shock wave therapy on the pain of trigger points in the upper fibers of the trapezius muscle.
A randomized, blinded clinical trial of 60 women (mean age 22.8 years and mean body mass index of 22.8 kg / cm2) with presence of trigger points in the upper fibers of the trapezius muscle. These were submitted to an initial evaluation (AV1), composed of the visual analogical pain scale, followed by an evaluation of the pain threshold, using algometry.
Then, the evaluation of the electromyographic activity of the upper trapezius muscle was performed, as well as of its muscular strength by manual dynamometry. Then allocated randomly in 3 groups: Control (n = 20), without intervention; Placebo (n = 20), simulation of the application of shock wave therapy; And shock wave therapy (n = 20).
Shock wave therapy was performed with the Master Plus 200® Storz Medical equipment, radial emission 2000 pulses, 15 Hz frequency and pressure of 1 Bar. All volunteers were evaluated immediately after the protocol (post evaluation) and 48 hours After the intervention protocol (evaluation 48 hours). A mixed ANOVA of repeated measurements was used for intra and intergroup comparisons, followed by tukey post hoc. Significance was set at 5% (p <0.05).

What is being measured
The primary outcome is the main question the study is designed to answer.
Pain assessment
The subjective pain intensity was evaluated using the Visual Analogue Scale. Which consists of a horizontal line, 10 centimeters long, marked at one end by a rating of 0 - "No Pain" and the other by the classification "Maximum Pain". The patient had to make a line perpendicular to the line, at the point that represents the intensity of his pain.
Measured: five minutes
Evaluation of trigger points
The presence of trigger points was investigated in the upper trapezius muscle on the side that the volunteer reported pain or bilateral.
The evaluation was performed with the volunteers in the ventral decubitus, and bilaterally evaluated the presence of the trigger points in the upper trapezius. The number of trigger points was recorded according to the classification: active PMG, latent PGM and total PGM. The side that presented a larger number of trigger points was the side used to evaluate the experimental procedures. If the number of active trigger points were equal on both sides, the upper limb considered dominant by the volunteer was chosen for the evaluation.
Measured: fifteen minutes
Evaluation of pressure pain threshold
To evaluate the pain threshold, a WAGNER® FDM algometer was used, which is a device consisting of a 1 cm2 rubber disc connected to a pressure gauge, which shows values in N.
The volunteers were previously advised on how the procedure would be performed. And that when when the pressure with the tip of the apparatus began to evoke pain / threshold it was necessary to say loudly the word "Stop"
Measured: ten minutes
Electromyographic Evaluation (EMG) Electromyographic Evaluation (EMG)
Electromyographic signal processing was performed with a TeleMyo DTS Desk Receiver® electromyography channel (Noraxon USA Inc., Scottsdale, USA) with a 20-500 Hz bandpass filter, gain of 1500 times, and a rejection rate of Common mode greater than 100 dB. The electromyographic evaluation was performed using the bipolar technique, with simple double wireless electrodes.
Measured: twenty minutes
Strength evaluation
The muscle strength test was performed with a manual dynamometer (Lafayette® - model 01165), for the force in the shoulder lift movement. For this evaluation the volunteers were seated, with the shoulder in extension position, and consequently the upper limb on the side of the body. The dynamometer was placed in a fixed bulkhead and the shoulder was elevated, resisting the movement and performing an isometric contraction.
Measured: ten minutes
Assessment by the Change Perception Scale
The Patient Global Impression of Change Scale questionnaire was applied in its Portuguese version, Scale of Perception of Change, being an instrument of easy understanding and application. It becomes a useful tool to quantify the perception of change in health status and satisfaction of a treatment of chronic musculoskeletal pain.
Measured: ten minutes

Primary outcome
Pain assessment
Time frame: five minutes
The subjective pain intensity was evaluated using the Visual Analogue Scale. Which consists of a horizontal line, 10 centimeters long, marked at one end by a rating of 0 - "No Pain" and the other by the classification "Maximum Pain". The patient had to make a line perpendicular to the line, at the point that represents the intensity of his pain.
Evaluation of trigger points
Time frame: fifteen minutes
The presence of trigger points was investigated in the upper trapezius muscle on the side that the volunteer reported pain or bilateral. The evaluation was performed with the volunteers in the ventral decubitus, and bilaterally evaluated the presence of the trigger points in the upper trapezius. The number of trigger points was recorded according to the classification: active PMG, latent PGM and total PGM. The side that presented a larger number of trigger points was the side used to evaluate the experimental procedures. If the number of active trigger points were equal on both sides, the upper limb considered dominant by the volunteer was chosen for the evaluation.
Evaluation of pressure pain threshold
