Resumen
Objective: To investigate the effects of extracorporal shock wave therapy (ESWT) on
on triggers point myofascial, pain and performance neuromuscular of upper trapezius
muscle fibers. Materials and methods: A randomized, blinded clinical trial of 60 women
(22.8 ± 2.95 years, mean weight of 55.68 ± 7.35 kg, height of 1.61 ± 0.59 cm and mass
index body weight of 21.37 ± 2.39 kg / cm2) with presence of trigger points in the upper
fibers of the trapezius muscle. They were submitted to an initial evaluation (AV1),
composed of the subjective report of pain (through the visual analogue scale),
evaluation of pain threshold (through algometry), number of active and latent trigger
points and activity electromyography of the upper trapezius muscle at rest and during
contraction.Instead, volunteers were allocated randomly into three groups: Control (n
= 20), without intervention; placebo (n = 20), simulation of the application of ESWT and
ESWT (n = 20). The ESWT was performed with the Master Plus 200® Storz Medical
equipment, radial emission of 2000 pulses, frequency of 15 Hz and pressure of 2 Bar,
tip of 6 mm2
. All volunteers were reassessed immediately and 48 hours after the
intervention protocol (evaluation 48 hours).A mixed ANOVA of repeated measures and
used for intragroup and intergroup comparisons, by Tukey post hoc. Significance was
set at 5%. Results: There was a reduction of pain due to VAS in the placebo group
and ESWT, the after 48 h was lower in all groups when compared to control. In the
variable number of total trigger points, we observed a difference between the ESWT
and placebo groups, also in the 48 h evaluation. No significant difference was observed
in pain threshold, electromyographic amplitude and peak torque analyzes.
Conclusion: A ESWT in the treatment of myofascial pain in women has the same
result as the placebo treatment.
