EFFECTS OF SHOCK WAVE THERAPY IN WOMEN WITH PAIN IN TRAPÉZIO MUSCLE
Condition: Pain; Muscle Tonus
MeSH terms: Shock
Study type: Interventional

Summary: 
      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).
    

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).
