Summary

The aim of the design is to investigate the value of percutaneous microelectrolysis (MEP) as an analgesic technique in myofascial trigger points. This research seeks to evaluate influence of cathode polar effects on the reduction of painful pressure (PPT) threshold and pain intensity (PI) in the myofascial trigger points (MTrPs) of upper trapezius muscle. An assessment with algometry and visual analog scale (VAS) will be made before applying the intervention. The study will evaluate changes in PPT and PI in a group exposed to percutaneous microelectrolysis (MEP) aplication compared to control group. Both groups will be provided with a baseline treatment of therapeutic ultrasound. Treatment will include three evaluation sessions. Subsequently, researchers will proceed to compare PPT and PI obtained from algometry test and VAS in each groups, and between groups, before and after the intervention. Changes obtained between sessions will be compared.

Conditions

  • Myofascial Trigger Point Pain (MTrP)

Interventions

DEVICE

Percutaneous microelectrolysis

284/5000 Application of Direct Current through an acupuncture needle with intensities in microamps (μA) in the PGm of the upper trapezius muscle. The acupuncture needle will correspond to the negative electrode or cathode. The intensity of work will be 610μA at the myofascial trigger point.

DEVICE

Ultrasound therapy

Application of conventional ultrasound (US) on PGm with a frequency of treatment 1MHz, intensity of 1.5W / cm2, ERA 5cm2, Duty Cycle 100%, treatment time 6 minutes.
